INTRODUCTION T h e Landing Craft, Infantry (Large) - L C I ( L ) - w a s a large beaching craft intended to transport and deliver an infantry rifle company to a hostile shore once the beachhead w a s secured, or as one soldier claimed: " T h e L C I was a metal b o x designed by a sadist t o move soldiers across the water." T h e L C I and its larger vehicle-delivery counterpart, the Landing Ship, Medium ( L S M ) , were important and widely used World W a r II amphibious-warfare ships. They were intermediate-size beaching craft, filling the gap between the much larger Landing Ship, T a n k ( L S T ) and the m a n y types o f smaller, bow-ramped, open cargo compartment landing craft. 1

T h e L C I was strictly a passenger carrier and could not transport vehicles. Lacking b o w doors or a ramp, cargo had to be hand-carried off the ship. T h e L C M , by contrast, could carry up t o five tanks and other large vehicles as well as bulk c a r g o . It lacked the a c c o m m o d a t i o n and sanitary facilities for large numbers o f t r o o p s , other than for a short ship-to-shore haul. (Passenger accommodations were only for transported vehicle crews.) T h e matter o f designations as " c r a f t " and " s h i p " must be addressed. Seagoing amphibious beaching vessels over 2 0 0 f t in length were designated ships. T h e L S M w a s 2 0 3 f t 6in long while the L C I ( L ) w a s 1 6 0 f t . T h e L C I , nevertheless, was a seagoing vessel given moderate conditions and reasonable ranges. T h e type was redesignated Landing Ship, Infantry (LSI) on February 2 8 , 1 9 4 9 , although few were still operational. T h e L C I and L S M were the smallest landing vessels assigned Bureau o f Ships (BuShips) hull numbers rather than names. Official names, for example, would be USS L C I ( L ) - 3 5 1 or USS L S M - 3 6 . Those provided to the Royal Navy retained the US BuShips hull numbers, but were designated H M L C I ( L ) - 2 , for example ( H M = H i s Majesty's). T h e Soviet N a v y designated them " D S " (desantnoye sudno - assault ship) and assigned n e w numbers (e.g. D S . 1 0 ) , though they retained US hull numbers up until December 1 9 4 5 . T o the sailors manning these a w k w a r d craft, they were k n o w n as the "Elsie I t e m " - " E l s i e " representing " L C " and " I t e m " being the phonetic alphabet word for " I . " Their boxy shape also led t o their being called the "Floating B e d p a n , " perhaps influenced by the close troop quarters and limited toilet facilities, while destroyer crews working with them as radar pickets called them "small b o y s . " In 1 9 4 3 / 4 4 , the L C I a n d L S M b o t h provided the hulls for n e w types o f rocket-firing g u n b o a t s , k n o w n as " b a z o o k a b o a t s . " A n o t h e r type based on 1 See Osprey New Vanguard 115, Landing Ship, Tank (LST)

the LCI's hull was the Landing Craft, Support (Large) M k 3 , the L C S ( L ) ( 3 ) . T h e L C S ( L ) was variously k n o w n as the " W h o o f u s " and " M i g h t y M i d g e t . " These were all specialized fire support craft intended to place suppressive fire on landing beaches using guns, automatic c a n n o n s , rockets, and m o r t a r s .

LANDING CRAFT, INFANTRY - DEVELOPMENT In late 1 9 4 1 and early 1 9 4 2 , development was u n d e r w a y for t w o large beaching vessels vastly different in size and capabilities, but designed as companion amphibious vessels. T h e L S T and Landing Craft, Tank ( L C T ) were both based on British requirements and versions were built on both sides o f the Atlantic. T h e L S T was a big ship, almost 3 3 0 f t in length and capable o f carrying 2 0 medium tanks, while the 1 1 4 f t L C T possessed a b o w ramp and an open c a r g o c o m p a r t m e n t c a p a b l e o f carrying five medium t a n k s . L S T vessels were c a p a b l e o f t r a n s - o c e a n i c m o v e m e n t , but the L C T was n o t so seaworthy and one of the LST's m a n y roles was to transport L C T s overseas either as deck cargo or disassembled and carried in the copious tank deck. T h e British had a n o t h e r r e q u i r e m e n t , w h a t they initially referred t o as a " g i a n t raiding c r a f t " ( G R C ) . T o keep the G e r m a n s in o c c u p i e d E u r o p e o f f balance, and to c o n d u c t some f o r m o f offensive o p e r a t i o n s , the British were executing m i n o r c o a s t a l raids. Small landing c r a f t were used in this r o l e , such as the Landing C r a f t , Assault ( L C A ) , a 4 1 f t b o a t carrying 3 5 t r o o p s . T h e s e l a c k e d the c a p a c i t y f o r t r a n s p o r t i n g m o r e t h a n just small d e t a c h m e n t s , and their e n d u r a n c e , speed, r a n g e , a n d c r o s s - C h a n n e l capabilities w e r e poor. W h a t w a s desired w a s a 1 5 0 f t b e a c h i n g vessel

LCS(L)(3)-3 clad in a navy green and pale green camouflage scheme. All LCSs were fitted with radar for surface search, air warning, and also positioning in order to fire their rockets accurately.

The pilothouse of LSM-34 was similar in design to that on LCI(L)-31 class boats, with "castle bridges" but taller, the height necessary in order to provide vision over the high forecastle and elevated bow ramp. The canvas awning over the conn was removed in combat zones to provide full overhead observation to detect aircraft.

T h e l o w - s i l h o u e t t e d vessel needed adequate air defense features and p r o t e c t i o n f r o m small a r m s fire, as it w a s e x p e c t e d t o discharge its raiders directly a s h o r e a n d n o t have to wait o f f s h o r e and c a r r y smaller landing craft t o deliver and retrieve the t r o o p s . It w o u l d also provide a c c o m m o d a t i o n for t r o o p s for up to t w o days. L o o k i n g into the f u t u r e , it w a s realized t h a t such a vessel w o u l d be valuable for the planned invasion o f the C o n t i n e n t .

LCI(L)-412 under construction at the George Lawley & Sons Shipbuilding Corp., Neponset, MA, in January 1944. The LCI's box-like hull design can readily be seen.

The stern of LCI(L)-443 provides a view of the large foot-like skegs protecting the props forward of the rudders. The kedge anchor and rack are on the transom and the engine exhaust and coolant water ports, emitting spray, can be seen on the side just above the waterline. To the right of the three stacked fog oil drums is the Besler smoke generator.

As an interim m e a s u r e , the British h a d c o n v e r t e d c r o s s - C h a n n e l ferries, m i n e s w e e p e r s , and o t h e r vessels into L a n d i n g Ships, Infantry, M e d i u m and Small - L S I ( M ) and L S I ( S ) . T h e s e vessels were a l m o s t 4 0 0 f t long a n d carried between 2 0 0 and 4 0 0 t r o o p s , depending on the particular ship. T h e y typically carried eight L C A s or similar landing craft - they were n o t beaching vessels. B y the time the d e v e l o p m e n t o f w h a t w o u l d b e c o m e the L C I was underway, the British h a d begun to c o n d u c t fewer c o a s t a l raids as the G e r m a n s strengthened the Atlantic Wall. Development continued, though, as the L C I w o u l d be an ideal c r a f t to deliver f o l l o w - o n infantry during the projected summer 1 9 4 3 invasion of France. It was not conceived as an initialw a v e assault c r a f t . T h e British c o m m i s s i o n hoping t o find a builder in A m e r i c a discovered that private builders such as Higgins were not only fully c o m m i t t e d t o c o n t r a c t s , but were running behind. British building capacity w a s unable to handle any additional projects. T h e US N a v y was none t o o interested in such a raiding craft and had little faith in larger landing craft, feeling they were t o o vulnerable to air a t t a c k . As with the LST, the British a p p r o a c h e d the US Army. In order for the US to construct Lend-Lease ships for the British, the design also had to be intended for use by the US armed forces. T h e US A r m y was indeed interested in the L C I , realizing the need to land larger f o l l o w - o n units t h a n w a s feasible by Landing C r a f t , Personnel ( L C P ) or Landing C r a f t , Vehicle ( L C V ) carrying a p l a t o o n - m i n u s . T h e British needed 3 0 0 craft by April 1 9 4 3 , a year away, and the design was little m o r e than a sketch. T h e r e were no shipping capabilities for vessels this size, so it had to be capable o f trans-oceanic crossings. It needed a 5 0 0 n m (575-mile) endurance and required a speed of at least 1 5 knots, 2 0 preferred. To save space and weight, and speed up production, a b o w r a m p and doors were forfeited. Instead the troops would disembark using three or four 2 f t 6in-wide g a n g w a y ramps f r o m weather-deck level. T h e r e was no capability to deliver even light vehicles,

wheeled crew-served weapons such as antitank guns, or bulk c a r g o . BuShips revised the design in M a y . It was hoped to be capable o f better than 1 5 k n o t s , beach on a 1 : 5 0 ratio gradient, and provide limited small arms fire protection. A r m a m e n t w o u l d be four 2 0 m m guns. Early p r o p o s a l s f o r e s a w it being unarmed when carrying troops, instead relying on the passengers' a r m a m e n t s , with 2 0 m m guns m o u n t e d w h e n n o t r o o p s were e m b a r k e d , t o prevent overloading. T h i s set-up, o f c o u r s e , w a s i m p r a c t i c a l as o n c e the t r o o p s debarked the vessel, in the forefront o f the action, the vessel was unable to protect itself from aircraft attacking the beachhead and shipping. T h e final design emerged as 1 6 0 f t long with a 2 3 f t b e a m , and h a d a forward beaching draft o f 2 f t 6in and 4 f t 5in at the stern. It could carry three weeks' stores for a crew of three officers and 2 1 enlisted men and six t r o o p officers and 1 8 2 enlisted men. Instead o f t r o o p s it could also carry 7 5 tons of cargo, but only in containers that a single stevedore could carry. It w o u l d be propelled by eight General M o t o r s engines, four per shaft. T h e design was kept simple, with as few curves as possible to speed up production. T h e result was a b o x y - l o o k i n g c r a f t with a blunt bow, flat b o t t o m , and a l o w rectangular deckhouse with an u n h a n d s o m e " s q u a r e b r i d g e " f o r w a r d o f the d e c k h o u s e . T h i s design w a s initially called the T r o o p T r a n s p o r t (ShortRadius) ( A P Y ) . P r o d u c t i o n began in J u l y 1 9 4 2 and the design w a s s o o n redesignated the Landing Craft, Infantry (Large) - L C I ( L ) . In this b o o k the " ( L ) " is not always included and does n o t refer to a different craft.

LCI(L) CONSTRUCTION T h e first A P Y c o n t r a c t w a s signed on J u n e 3 , 1 9 4 2 . T h e first c o n t r a c t e d yards were G e o r g e Lawley 8c Sons Shipbuilding C o r p . , N e p o n s e t , M A , and N e w Y o r k Shipbuilding C o r p . , C a m d e n , N J . N e w Jersey Shipbuilding C o r p . , Barber, N J , would be the m o s t prolific o f the ten builders. T w o p r o t o t y p e LCI(L)s were launched, L C I - 1 and L C I - 2 0 9 (the latter actually the first t o be completed), and were tested in September and O c t o b e r 1 9 4 2 , respectively. It was found that they could beach and retract very well, but they c o u l d n o t maneuver in reverse. O n e b o a t had been built without prop skegs, the guards protecting the propellers, and turned in a 7 5 y d radius. T h e b o a t with skegs required a 1 0 0 y d radius. Regardless, since the props were so vulnerable t o beaching d a m a g e it was directed that all b o a t s have skegs. T r a n s - A t l a n t i c crossing w a s c r i t i c a l , and eight L C I s a c c o m p a n i e d by three tugs sailed from N o r f o l k , VA, to B e r m u d a in late 1 9 4 2 . T h e y w e a t h e r e d F o r c e 4 winds ( 1 3 - 1 8 m p h ) and 8ft seas, proving they were c a p a b l e o f such a passage in m o d e r a t e weather. T h e b o a t s m a d e 1 1 k n o t s , but rolled and yawed badly, and heavy b o w - o n w a v e s a c t u a l l y rippled the hull p l a t e s . A redesign increased the d i s p l a c e m e n t , however, so t h a t they drew s o m e 6 f t o f w a t e r when fully loaded for o c e a n t r a n s i t , with a speed just shy o f 1 4 k n o t s in fair weather. T h e y were t o o s l o w t o accompany attack transport groups and h a d t o depart p o r t a h e a d o f the faster ships along with the L S T s .

LCKU-351, the lead ship of the 351 class, was commissioned in May 1943. It was converted to an LCI(G) in December 1944 and to an LCI(M) in April 1945. The boat was struck from the Naval Register in 1946 and sold for scrap in 1948. Such was the typical life of an LCI.

T h e 2 9 9 L C I ( L ) - 1 class boats ( 1 - 4 8 , 6 1 - 1 3 6 , 1 6 1 - 1 9 6 , 2 0 9 - 3 5 0 ) were built largely according to British plans owing to Britain's urgent need. Various changes were m a d e to the original British design to a c c o m m o d a t e American c o n s t r u c t i o n m e t h o d s . O t h e r changes eliminated the bench-type main deck t r o o p seats (behind the b u l w a r k and alongside the deckhouse), changed the bicycle ( x l 2 ) stowage c o m p a r t m e n t to general storage, and added a level to the bridge to provide the c o n n with better vision over the bow. Construction time varied and improved with experience, but on average c o n s t r u c t i o n t o o k 5 - 6 weeks f r o m laying d o w n the keel to launching and a b o u t another 5 - 6 weeks for fitting before the vessel was commissioned. T h e craft were constructed in sections, essentially end-to-end b o x e s , which were simply welded together on the slip. At the height of construction, in some yards a new L C I was sliding down the ways at the rate of one every day or t w o . Although the L C I was considered a f o l l o w - o n landing craft, it was still provided with some armor. T h i s was 1 5 l b per square foot special treatment steel (STS) protecting the bridge and c o n n . T h e forward third of the hull sides a n d the b u l w a r k f o r w a r d o f the d e c k h o u s e were 101b S T S . T h e b u l w a r k , t w o parallel l o w steel walls on the f o r w a r d w e a t h e r deck, protected t r o o p s preparing t o d e b a r k as well as the egress hatches f r o m the t r o o p c o m p a r t m e n t s . T h e bridge, c o n n , and gun tubs were additionally protected by 2 % i n plastic armor. Lessons were learned and flaws were uncovered in the L C I - 1 class and it w a s n o t long before a redesign was underway. Forty-five L C I - I s were canceled so that an improved design could be built sooner. T h e deckhouse o f the n e w L C I - 3 5 1 class was extended f o r w a r d and widened to the hull sides. T h e egress hatches f r o m t r o o p c o m p a r t m e n t s N o . 2 - 4 were n o w enclosed by the deckhouse, reducing problems troops had coming topside in foul weather; only N o . 3 was so protected on the L C I - 1 class. T h e hatches were enlarged t o a c c e p t litters. Previously there was deck space on either side o f the d e c k h o u s e allowing free p a s s a g e . N o w one had to pass through the deckhouse when moving fore and aft. T h e enlarged deckhouse provided more messing, troop officer a c c o m m o d a t i o n , and crew w o r k areas necessary for the v o y a g e s , w h i c h were longer t h a n originally envisioned. Galley space, r e f r i g e r a t i o n units a n d the n u m b e r s o f toilets and w a s h r o o m s were also

LCKU-1 CLASS AND LCKD-351 CLASS 1: LCI(L)-1 CLASS This early production boat retains the seldom-used steadying sail mast on the aft end of the deckhouse. These masts were later removed. It also features the "park bench" seats along the port inboard side of the bulwark, but similar seats on the outside of the bulkheads of the deckhouse were deleted. The early boats were armed with four 20mm guns. This boat is painted haze gray, but once in the Pacific was repainted in a green camouflage scheme. Gray was often retained in the Mediterranean and the English Channel. Small white hull numbers were used to limit the vessels' visibility. It was soon found that larger numbers were necessary for control purposes and this necessity overruled low visibility. 2: LCKD-351 CLASS The much redesigned and improved 351 class offered accommodations for lengthier cruises and added a fifth 20mm gun. The hull did not change, but the deckhouse was enlarged and there was some internal compartment redesign. The Pacific dapple camouflage scheme was designed to blend into the vegetated shoreline of islands in the background (from water level). This scheme was especially effective in the Solomons, with its many closely gathered islands. In daylight the vessels would moor at the shore's edge to blend into the trees. The round "castle bridge" is apparent as opposed to the "square bridge" on the earlier class.

T h e first L C I ( L ) - 3 5 1 class w a s laid d o w n on M a r c h 5 , 1 9 4 3 , launched on April 8 , and c o m m i s s i o n e d on M a y 1 4 . This lead ship and others w o u l d be converted to g u n b o a t s and then m o r t a r boats. A t o t a l o f 5 9 5 L C I ( L ) - 3 5 1 class were built: 3 5 1 - 7 1 6 , 7 3 1 - 7 8 0 , 7 8 4 - 8 2 1 , 8 6 6 - 8 8 4 , 9 4 3 - 1 0 3 3 , and 1 0 5 2 - 1 0 9 8 (inclusive o f the L C I - 4 0 2 subclass). M a n y o f the users called for a centerline b o w r a m p and doors similar to those on an LST. Such features w o u l d allow troops to debark faster and at b e a c h level rather than being e x p o s e d while descending the n a r r o w ramps. B u l k i e r c a r g o c o u l d also be o f f l o a d e d faster by h a n d . T h e p r o t o t y p e was L C I ( L ) - 4 0 2 . B o w doors were installed on craft built after J u n e 1 , 1 9 4 4 , to include: 4 0 2 , 6 4 1 - 6 5 7 , 6 9 1 - 7 1 6 , 7 6 2 - 7 8 0 , 7 8 2 - 8 2 1 , 8 6 6 - 8 8 4 , 1 0 2 4 - 1 0 3 3 , and 1 0 6 8 - 1 0 9 8 . O t h e r changes to this subclass were minor. A total o f 2 1 1 L C I ( L ) s were transferred to the R o y a l N a v y under LendLease f r o m 1 9 4 3 , with the crews trained in the States. In early 1 9 4 5 , 2 5 more were transferred to the U S S R , with the crews trained by C o a s t Guardsmen at C o l d Bay, A l a s k a . N o fire support types were transferred to either navy.

Armament LCIs were provided with only light anti-aircraft armament, four or five 2 0 m m guns. Later versions substituted a 4 0 m m for the b o w 2 0 m m . T h e various fire support craft had a much varied armament, with combinations of 2 0 m m and 4 0 m m cannons, 3in or 5in guns, 4.2in mortars, and 4.5in or 5in barrage rockets. T h e O e r l i k o n 2 0 m m M k 4 a u t o m a t i c c a n n o n was the standard armament o f L C I s and L S M s . Fed by 6 0 - r o u n d snail drum m a g a z i n e s , it rattled out shells at 5 5 0 r p m with a 2 , 0 0 0 y d range and was m a n n e d by a crew of five. M k 2 4 twin m o u n t s w e r e fitted on later L S M ( R ) s and added t w o men. N u m b e r s o f . 5 0 c a l M 2 B r o w n i n g air-cooled m a c h i n e guns were mounted on L C I g u n b o a t s and L S M ( R ) s , mostly on the fantail, as were Browning . 3 0 c a l M 1 9 1 9 A 4 m a c h i n e guns on L S M ( R ) s . T h e s e served as last-resort weapons against air a t t a c k , but were also useful against small attack boats. T h e British usually m o u n t e d t w o . 3 0 3 i n Lewis M k I m a c h i n e guns for air defense on their L C I ( L ) s . Heavier anti-aircraft w e a p o n s were provided in the form o f 4 0 m m Bofors guns on the g u n b o a t s . T h e s e were also used against targets ashore. T h e dual M k 1 m o u n t was usually on the stern and/or b o w and consisted of a M k 1 right gun a n d M k 2 left gun. T h e s e were US N a v y w e a p o n s employing p o w e r e d m o u n t s a n d were w a t e r - c o o l e d , m a k i n g t h e m c a p a b l e o f a high sustained rate o f fire. T h e single-barrel 4 0 m m M k 3 gun was a US Army M l on a US N a v y M k 3 m o u n t ; often A r m y M l m o u n t s were simply welded to the deck in the rush to convert L C I s to g u n b o a t s , plus the m o u n t was smaller and lighter. T h e s e were air-cooled and manually trained. Single and dual guns had four- and seven-man crews, respectively. T h e " f o r t y - m i k e - m i k e " was fed by four-round clips and fired at 1 2 0 - 1 8 0 r p m to 5 , 0 0 0 y d .

T h e L S M ( R ) boasted the heaviest a r m a m e n t in the f o r m o f the 5in ( 3 8 c a l ) M k 1 2 gun in a fully enclosed M k 3 0 turret, as used on destroyers. T h i s gun threw a 5 5 l b shell to a range o f 1 7 , 0 0 0 y d . T h e 1 2 - m a n crew, using ready rounds in the turret, could h a m m e r out 2 5 r p m . W i t h a steady supply o f a m m u n i t i o n f r o m the m a g a z i n e , they c o u l d m a i n t a i n 1 5 r p m . W h i l e the vessel's rocket a r m a m e n t (see below) saturated the target area, the 5in was an accurate and potent w e a p o n against point targets with high-explosive (called " c o m m o n " by the N a v y ) , a n t i - a i r c r a f t , a r m o r - p i e r c i n g , a n d i l l u m i n a t i o n (called " s t a r " by the N a v y ) shells.

A little-used w e a p o n found on some g u n b o a t s and L C S ( R ) s was the 3in (50cal) M k 2 2 dual-purpose gun. T h i s was often m o u n t e d in lieu o f a twin 4 0 m m . T h e outdated M k 2 2 was moderately effective against aircraft but t o o light for surface targets, and the high rate o f 4 0 m m fire w a s m u c h preferred over the 3in's 1 8 r p m . It had a 1 4 , 0 0 0 y d r a n g e , w a s m a n n e d by seven men, and used the same type o f a m m u n i t i o n as the 5in gun. L C I ( M ) s and L S M ( R ) s also m o u n t e d four US A r m y 4 . 2 i n M 2 m o r t a r s . These w e a p o n s , relatively small c o m p a r e d to other naval a r m a m e n t , had a 6 0 0 - 3 , 2 0 0 y d range - further than the 4 . 5 i n r o c k e t - but they could n o t be fired to their full 4 , 4 0 0 y d range because o f the stress inflicted on the deck. While the barrage-launch o f 4 8 0 rockets was an impressive display, reload time was considerable and demanding on manpower. A 4 . 2 i n m o r t a r could fire 4 0 rounds in the first t w o minutes and 1 0 0 rounds in the first 2 0 minutes. T h e four mortars together could each keep up a steady barrage o f 6 0 rounds an hour indefinitely. Ammunition included high-explosive, white phosphorus, and illumination. T h r e e types o f b a r r a g e r o c k e t s w e r e l a u n c h e d f r o m fire s u p p o r t c r a f t . These rockets were developed and fielded in a r e m a r k a b l y short time. T h e 11

4 . 5 i n " O l d F a i t h f u l " beach barrage r o c k e t was quickly designed using the m o t o r o f the 2 . 2 5 i n M o u s e t r a p anti-submarine rocket fitted with a 201b general-purpose b o m b . It was first fired in late J u n e a n d t h o u s a n d s were launched during the N o r t h Africa invasion in N o v e m b e r 1 9 4 2 , but f r o m L C T s , not L C I s . T h e 4 . 5 i n r o c k e t was fin-stabilized with only a 1 , 1 0 0 y d range, and was none t o o accurate. Both high-explosive and white phosphorus warheads were provided. A slightly longer-ranged model with a longer rocket m o t o r was provided in 1 9 4 4 . T h e barrage rockets ( B R ) were fired f r o m several types o f launcher racks: M k 1 - 1 2 rockets in four layers, elevatable, but non-trainable. M k 7 - 1 2 - r o c k e t gravity-fed r a c k s . Preset elevations, but nontrainable. Fired 1 2 rockets in four seconds. M k 8 - 1 2 r o c k e t s , modified M k 1 with fixed elevation, nontrainable. M k 11 - Improved M k 7 capable o f jettisoning misfires. M k 2 2 - 1 2 r o c k e t s . Elevatable, fixed train. 2

Because o f the inadequate range and accuracy o f the 4 . 5 i n , development o f a new r o c k e t began in M a y 1 9 4 3 . T h e 5in high-velocity spinner rocket ( H V S R ) began to be fitted on r o c k e t boats in late 1 9 4 4 . T w o m o t o r variants w e r e available offering 5 , 0 0 0 y d and 1 0 , 0 0 0 y d ranges with various highexplosive, semi-armor-piercing, and white phosphorus warheads. T h e M k 5 1 was a single rail launcher similar to the M k 7 capable o f automatically firing 1 2 rockets in 4 . 5 seconds. T h e M k 1 0 2 was a trainable, automatically loaded (from below deck) twin-tube launcher capable of firing 3 0 rockets per minute. 3

As an interim measure owing the non-availability of the new 5in H V S R , the first L S M ( R ) s were fitted with racks for the much longer fin-stabilized 5in forward-firing aircraft r o c k e t ( F F A C ) . Fitted with high-explosive and white phosphorus warheads, it had only a 1 , 7 0 0 y d range. T h e late-war launchers required long rails: the M k 3 0 had six rails and the M k 3 6 four. Both were fixed in train, but the M k 3 0 was elevatable while the M k 3 6 was fixed at 4 5 degrees. A Type C r a c k for a single 3001b M k 6 depth charge was fitted on either side o f the fantail on the L C I ( L ) - 1 class, the idea being that the L C I s could 2 M k 1 M o d 0 was port, M k 1 M o d 1 was starboard. 3 These are often identified as " S S " rockets, which means "spin-stabilized," but are sometimes misidentified as "ship-to-shore."

LCKD-402 CLASS AND LCS(L)(3) 1: LCKD-402 CLASS From June 1944, LCIs began to be built with a bow ramp and doors and a redesigned forecastle. Some vessels of this LCI(L)-402 class were converted to LCI(R)s, with rocket launchers on the forward deck and a 40mm gun on the forecastle, and LC(FF)s. The pale blue upper hull and deckhouse and navy blue lower hull scheme were often used in the English Channel. 2: LCS(L)(3) While the hull was the same, with some modification of the bow, and the "castle bridge" was used, the LCS(L) bore little resemblance to the LCI(L) on which it was based. Ten rocket launchers were fitted just forward of the deckhouse and No. 2 gun tube, but it was foremost a gunboat, with twin 40mms forward of the pilothouse and on the fantail. The bow featured a 3in or single 40mm gun, or a twin 40mm. A common camouflage scheme was for the hull to be painted black from the stern to a point at the forward gun and angled to appear as a vessel's bow. The forward position of the hull, deckhouse, gun tubes, other fittings, and the bulwark from the No. 2 gun mount (3in gun in this case) forward to the bow were haze gray. Some vessels had a broad black waterline band and red hull bottom.

help protect convoys from submarines. These were often later removed and were n o t installed on the L C I ( L ) - 3 5 1 class. M o s t L C I s had a Besler fog oil smoke generator on the fantail and were also provided with M 3 or M k 2 smoke pots, which could be burned in o n b o a r d racks, or M 4 A 2 floating pots dropped over the side.

LCI(L) DESCRIPTION T h e L C I ( L ) was the third-largest o f the beaching craft, being outsized by the L S T and L S M . While not intended as an assault c r a f t , it w a s a c o m b a t a n t built to beach itself on a hostile shore where it could be under artillery, m o r t a r , a n d small a r m s fire as well as e x p o s e d to air attack. In the fire support role, while operating offshore, it was also exposed to and drew heavy fire.

F r o m the keel up, an L C I had four or five levels. T h e hold w a s divided into dozens o f c o m p a r t m e n t s including ballast t a n k s , fuel oil tanks, fresh water tanks, 8,000 miles and voids. T h e L C I ( L ) - 1 class held 1 2 0 t o n s o f fuel, 2 4 0 g a l o f lubricating oil, and 3 6 t o n s o f fresh water, while the L C I ( L ) - 3 5 1 class carried 1 0 tons less fuel and one ton m o r e water. T h e first p l a t f o r m contained four t r o o p c o m p a r t m e n t s , engine r o o m , crew quarters, storage, and steering gear. T h e main or weather deck forward o f the d e c k h o u s e c o n t a i n e d only the b u l w a r k sheltering t r o o p s on deck.

Aft of the d e c k h o u s e w a s the fantail. T h e deckhouse was divided into numerous c o m p a r t m e n t s to a c c o m m o d a t e the crew, passengers, and vessel operations. T h e bridge was at the deckhouse's f o r w a r d end and included the raised conn. O n e or four guns, depending on the class, were atop the deckhouse. 15 / knots 1

T h e engine r o o m was b e l o w the aft end of the deckhouse. Propulsion was provided by eight G e n e r a l M o t o r s D e t r o i t 6 - 7 1 t w o - s t r o k e , six-cylinder, 2 2 5 h p diesel engines. T h e s e collectively developed l , 8 0 0 h p . M o s t ships had one large engine per shaft, but a suitably sized and powered engine did not exist f o r the L C I . It w o u l d have required far t o o long to develop such an engine and engine factories were already overloaded. An ingenious solution w a s f o u n d by linking four engines together t o p o w e r each shaft. T h e G M 6 - 7 1 was a tried and proven design used for buses, t r u c k s , t a n k s , t u g b o a t s , and g e n e r a t o r s . N o r m a l l y , linking four engines to a c o m m o n r e d u c t i o n gear w o u l d develop h a r m o n i c oscillations capable o f breaking crankshafts. T h i s p r o b l e m w a s o v e r c o m e by using dry disc clutches with just enough plate tension t o a l l o w the clutch t o slip w h e n a b n o r m a l vibrations o c c u r r e d . T h e oscillations would then go out o f phase with one another. Individual engines could be taken offline

while underway (with a slight speed reduction) for servicing. T h e r e were instances when L C I s limped into p o r t on one t o three engines that were kept running on parts cannibalized f r o m the others. Each engine had an exhaust line with a small port just above the waterline, four on each side. Seawater b o t h c o o l e d the engines' heat exchangers and quietened the wet-type M a x i m silencers. H o t coolant water and exhaust fumes were discharged through the same exhaust p o r t s . T h i s system enabled an L C I t o a p p r o a c h a hostile shore in comparative silence. T w o G M 2 - 7 1 two-cylinder versions o f the main engines powered the t w o 2 0 k W p o w e r generators for the 1 2 0 - v o l t D C electrical system. T h e r e were dozens o f small electric m o t o r s to operate water, fuel, and bilge pumps, fire fighting systems, etc. T h e engines were n o t c a p a b l e o f running in reverse, w h i c h w a s o f c o u r s e essential for d o c k i n g m a n e u v e r s a n d e x t r a c t i n g f r o m a b e a c h . T w o b r o n z e 4ft-diameter variable-pitch propellers were provided for this p u r p o s e . T h e y were always turning in the same direction, but w h e n reverse w a s required an electric servo m o t o r , l o c a t e d b e t w e e n the f o r w a r d t w o engines, reversed the angle o f the t h r e e b l a d e s t o the a s t e r n p i t c h . T h e p r o p e l l e r s t u r n e d constantly, even w h e n the ship c a m e to a rest, w h e n the blades were pitched t o the f e a t h e r i n g p o s i t i o n w h e r e they i m p a r t e d n o m o v e m e n t . T h e p i t c h m o t o r o p e r a t e d f r o m 2 4 - v o l t b a t t e r i e s in the event t h a t b o t h p o w e r generators were lost. T w o additional electric m o t o r s p o w e r e d the steering, which was p e r f o r m e d by t w o rudders. If the p o w e r g e n e r a t o r s were lost, there was a m a n u a l steering s t a t i o n o n the f a n t a i l . A s o u n d - p o w e r e d telephone provided steering instructions f r o m the c o n n t o the wheel station, which was blind f o r w a r d .

Below decks In the narrow b o w beneath the forecastle were voids and stores compartments. T h e layout was similar on both the L C I ( L ) - 1 and 3 5 1 classes. T r o o p compartment capacity for each compartment is parenthesized, the first number for the LCI(L)-1 class, second for the 3 5 1 class, and the third for the 4 0 2 class: troop compartment N o . 1 (46/48/47); N o . 2 (58/62/62); and N o . 3 (67/67/63). Doghouse hatches to the main deck for N o . 1 and 2 were within the f o r w a r d b u l w a r k , while N o . 3 exited into the d e c k h o u s e on the L C I ( L ) - 1 . O n the L C I ( L ) - 3 5 1 b o t h N o . 2 and 3 gave access into the d e c k h o u s e . T h e c r e w quarters a c c o m m o d a t i n g all enlisted m e n was aft o f t r o o p c o m p a r t m e n t N o . 3 and forward of the engine r o o m , while the engine r o o m was below the aft end o f the deckhouse and also housed the p o w e r generators. N o . 4 t r o o p c o m p a r t m e n t (28/23/26) was aft of the engine r o o m with a ladder leading to a c o m p a n i o n w a y nnected to the deckhouse on the 3 5 1 and 4 0 2 classes. O n the L C I ( L ) - 1 class it was protected only by a d o g h o u s e hatch on the fantail. T w o provisions compartments were to the aft o f the N o . 4 t r o o p c o m p a r t m e n t with a c o m p a n i o n w a y separating them and connecting the t r o o p c o m p a r t m e n t and the steering gear compartment in the lazarette (aft-most compartment).

LCKD-419 beached on Utah Beach, Normandy. Engine coolant intakes were on the hull bottom on most ships, but since the LCI was by nature frequently run aground, they were on the sides where they would not suck up sand. In the English Channel, US vessels bore a large "US" while British vessels lacked identifying letters.

Q ANATOMY OF AN LCI(L)-351 CLASS

The LCI(L) consisted of three levels. The "first platform" contained various storage spaces, four troop compartments, crew quarters, and engine room. Beneath this was the "hold," divided into many small compartments for ballast, fuel, water and serving as voids. The "main deck" included the forward deck with the bulwark and the fantail aft of the deckhouse. The "deckhouse" contained a surprising number of compartments and facilities to serve the crew and passengers and operate the vessel. The "forecastle and deckhouse" topside mounted the armament and the pilothouse.

Deckhouse T h e m a j o r difference between the 1 class and 3 5 1 class was the deckhouse. T h e 1 class had a comparatively small rectangular deckhouse with the bridge f o r w a r d . O f t e n called the " s q u a r e b r i d g e , " it was actually trapezoid in shape with a radio m a s t positioned a b a f t . T h e antenna wire ran forward to a short m a s t a b a f t the forecastle gun. T h e l o w e r p o r t i o n o f the bridge was the

Originally a tall m a s t w a s fitted a b a f t the d e c k h o u s e , intended to rig a triangular steadying sail. T h i s was to reduce rolling in rough seas, but did little to steady the ship, and was usually removed.

ABOVE LEFT Details of an LCI's 2ft 6in-wide troop ramp. On the LCI(L)-1 class it was 28ft long and 32ft on the LCKD-351 class. The longer ramp provided a less steep incline for equipmentladen troops. Cable handrails and tread slats aided the troops on a wet ramp. The I-beam cathead supporting the ramp's block-and-tackle was pivoted inboard when not in use.

T h e 3 5 1 class deckhouse was considerably larger in length and breadth. It extended further forward and aft and occupied the full width o f the deck. R a t h e r than being rectangular, its corners were rounded with a 2 0 m m tub on each. T h e m o s t notable feature was the high r o u n d bridge called a " c a s t l e bridge" set one-third o f the w a y b a c k a t o p the deckhouse. T h e r e w a s a h a t c h on both sides, with ports all r o u n d , and a ladder to the aft for access to the conn, beside which was a radio and signal mast. Ladders on the f o r w a r d and aft ends o f the deckhouse accessed its topside. A central passageway ran the length of the deckhouse. O n the starboard side was a mess, small w a r d r o o m , galley, and refrigerator r o o m s . O n the port side were t r o o p and ship's officer quarters, chart and radio r o o m , captain's cabin, officer's head and w a s h r o o m , and crew head and w a s h r o o m .

ABOVE RIGHT Here we can see the design differences between the LCI(L)-351 class with two troop ramps (right) and the LCI(L) 402-subclass with bow doors and a 4ft 6in-wide single ramp (left).

Forecastle and ramps T h e raised forecastle platform housed toilets and a w a s h r o o m for the troops plus the b o w anchor winch. M o r e facilities were added to the 3 5 1 class, which also had a slightly raised overhead platform. A t o p the forecastle was a 2 0 m m tub and a spare anchor was stowed there. T h e main anchor was housed on the forepeak. A very few 3 5 1 class lacked the b o w 2 0 m m . A 2 f t 6in-wide r a m p was fitted on either side of the forecastle, 2 8 f t long for the 1 class and 3 2 f t for the 3 5 1 class. Stanchions with cable handrails were fitted on both sides o f the ramps. Retractable catheads (arms supporting block-and-tackle) were fitted to the forepeak to support the tackle lowering and raising the r a m p s . T h e y were lowered by hand on the 1 class and by the a n c h o r winch on the 3 5 1 class. 19

Some boats had alternate debarkation ladders stowed on the o u t b o a r d bulwark sides. These were placed almost vertically on either side of the forepeak forward of the ramp catheads. T h e ramps, w h a t the British called " b r o w s , " were sometimes torn off by heavy surf or fouled in w r e c k a g e . T h e 4 0 2 class, with an internal b o w r a m p , had a m u c h rearranged f o r e c a s t l e . T h e single centerline g a n g w a y r a m p angled d o w n w a r d to the drop r a m p . T h e r a m p was accessed from the weather deck and not the f o r w a r d t r o o p c o m p a r t m e n t . A wide d o u b l e h a t c h was provided in the forecastle's aft bulkhead to access the r a m p . T h e b o w r a m p only extended 4 f t and was 4 f t 6in wide. A 2 0 f t extension ramp o f the same width could be slid out to reach 1 6 f t beyond the ramp's end. T h e b o w doors were secured by turnbuckle dogs. D o o r s and r a m p were operated by cables via a heavy winch fitted in the center o f the main deck. T h e bulwarks were moved outboard t o the side o f the hull t o provide m o r e unrestricted deck c a r g o s p a c e . T h e interior o f the forecastle n o w served as storage with the head and w a s h r o o m in the deckhouse. The closed bow doors of LCI(L)-402. This craft is painted haze gray, as were most LCIs destined for the Mediterranean and Europe. Those for the Pacific were usually colored green in the yard and sometimes even painted in a camouflage scheme. This also provides details of the bow anchor.

LCI VARIANTS T o serve as c o m m a n d ships for landing craft flotillas, 4 9 LCIs were converted in late 1 9 4 4 to Landing Craft (Flotilla Flagship) - L C ( F F ) . These served as flotilla leaders not only for L C I units, but L S M and L S T units also. (It was impractical to convert these larger landing ships to c o m m a n d ships due to the loss o f cargo capacity.) Externally the L C ( F F ) appeared no different than a standard L C I other than having a small radar dome atop the mast and a long whip antenna aft of the pilothouse. T h e troop compartments were converted to a c c o m m o d a t e the increased complement, with N o . 1 compartment becoming the enlisted staff quarters, N o . 2 the staff w o r k s p a c e , N o . 3 being divided into t w o - m a n cabins for up to eight staff officers, and N o . 4 serving as 4

4 Flotilla staff officers included communications and engineering officers, paymaster, and doctor.

LCI FIRE SUPPORT CRAFT The various fire support craft based on the LCI(L) were converted from LCI(L)-1 class, LCI(L)-351 class, and even the LCI(L)-402 class with a bow door and ramp. As well as being converted while under construction in US yards, they were also converted overseas in advance naval bases. Armament configurations varied between craft of the same type, sometimes drastically. 1: LCI(G)-397 was converted to a Type B gunboat in June 1943. Besides the early Pacific theater gunboat conversions, those converted in the United States had one of six battery configurations. The types A, B, and E were built on LCI(L)-351 and 402 class vessels and the Types C, D, and F on the LCI(L)-1 class. Only the 20mm, 40mm, and 3in guns are depicted on the plan diagrams for the LCI(G)-351 class gunboats. The rocket launchers were mounted in place of the troop ramps. Full armament is described in the text. 2: LCI(R)-73 was a 1 class boat outfitted with 12 x 4.5in Mk 1 rocket launchers. 3: LCI(M)-265 mounted a 40mm on the bow, 4 x 20mm in the usual LCI(L)-351 class manner on the deckhouse, and three 4.2in mortars, one on the centerline between the bulwarks and two immediately forward, either side of the deckhouse.

provisions storage. T h e former t r o o p officers' quarters was converted into the flotilla commander's cabin. There were t w o 3 0 k W generators instead of 2 0 k W and a water evaporator was installed as well as additional radios. Besides c o m m a n d , operational planning, and coordination, the flotilla relied on the L C ( F F ) to guide the other craft to their destination. Some of these craft were in action at O k i n a w a and proved to be too slow and small to provide the necessary a c c o m m o d a t i o n s and workspace and they were retired at the war's end. Conversions to L C ( F F ) were: 3 6 7 - 3 7 0 , 3 9 9 , 4 2 3 - 4 2 7 , 4 8 4 - 4 8 6 , 503, 504, 531-533, 535, 536, 569, 571, 572, 575, 627, 628, 656, 657, 679, 775, 782, 783, 788-793, 9 8 8 , 9 9 4 , 9 9 5 , 9 9 8 , 1 0 3 1 , and 1 0 7 9 - 1 0 8 3 .

Earlier s o m e L C I s were converted locally to flagships in the M e d i t e r r a n e a n and k n o w n unofficially as L C I ( H ) H e a d q u a r t e r s . T h e s e were also used at N o r m a n d y and in late 1 9 4 4 a d d i t i o n a l c o m m u n i c a t i o n s capabilities were added to 1 1 L C I s as L C I ( L ) ( C ) s - C o m m a n d - to support the southern F r a n c e landing. T h e r e were t w o other unofficial conversions, produced with only m i n o r internal m o d i f i c a t i o n s m a d e in-theater. T h e L C I ( A ) s - A m m u n i t i o n - were standard L C I s with the N o . 2 t r o o p c o m p a r t m e n t bunks removed to store 1 , 2 0 0 rounds o f 4 . 2 i n m o r t a r ammunition. These craft supported L C I ( M ) s , with an enlarged c r e w to pass ammunition. T h e L C I ( D ) s - Diver - t r a n s p o r t e d a n d served as m o t h e r ships for 1 0 0 - m a n u n d e r w a t e r d e m o l i t i o n t e a m s ( U D T s ) . T h e L C I ( D ) vessels were numbered 2 9 , 4 4 , 2 2 7 , and 4 4 8 . W h e n the c o n c e p t o f the fire support craft was developed, the L C I ( L ) was considered ideal f o r c o n v e r s i o n . It was large enough to m o u n t substantial a r m a m e n t , h a d sufficient space for a m m u n i t i o n and a larger crew, could operate in shallow inshore w a t e r s , was capable o f seagoing operations (thus allowing it t o self-deploy t o objective islands), and c o n v e r s i o n w a s at a relatively l o w cost. In addition, there was a surplus o f L C I s being built, so conversion w o u l d n o t limit the availability o f dedicated troop-carrying L C I s . T h e gun-, r o c k e t - , and m o r t a r - a r m e d craft were o f similar layout, but with different m i x e s o f a r m a m e n t . T h e y were n o t armed purely with the stated a r m a m e n t : m o r t a r and r o c k e t b o a t s had guns and m o s t of the gunboats also had r o c k e t s . T h e internal c o m p a r t m e n t arrangement was changed, with N o . 1 f o r w a r d t r o o p c o m p a r t m e n t b e c o m i n g a stores c o m p a r t m e n t , N o . 2 troop c o m p a r t m e n t converted t o a m a g a z i n e , the amidships t r o o p c o m p a r t m e n t n o w being for the additional crew, and the aft t r o o p c o m p a r t m e n t serving as a n o t h e r magazine. T h e superstructure changed little (both square and round bridge classes were used), except for the addition o f fire-control systems. T h e t r o o p r a m p s were usually r e m o v e d , as often were the bulwarks. A r m a m e n t a r r a n g e m e n t varied greatly, even between craft o f the same type.

L C I ( G ) - 2 2 , 2 4 , 6 8 , a n d 6 9 were c o n v e r t e d at N e w C a l e d o n i a in August 1 9 4 3 , m o u n t i n g l x 3in, 1 x 4 0 m m aft, 4 x 2 0 m m , and 6 x . 5 0 c a l 22

Some o f these craft were in turn converted to L C I ( M ) s . 5

Landing Craft, Infantry (Rocket) In April 1 9 4 4 , L C I ( G ) - 3 1 , 3 4 , and 7 3 were converted in-theater to r o c k e t boats with 2 4 x 4 . 5 i n M k 1 or M k 8 launcher racks with 6 0 0 rockets and 5 * = Later converted to LCI(R). t = Later converted to LCI(M).

LCI(G)-346 and 348 were Type A gunboats armed with 2 x 40mm, 3 x 20mm, and 6 x .50cal guns and 10 x 4.5in Mk 7 rocket launchers. The troop ramps were removed from gunboats. While there were standardized camouflage schemes, it was not uncommon for crews to apply their own - note the differences in the two boats' patterns. 23

storage for 1 , 0 0 0 m o r e . A 4 0 m m gun was mounted on the forecastle and two 2 0 m m guns on the fantail. Additional boats were temporarily converted in time t o be used in the M a r s h a l l s at the beginning of 1 9 4 4 and unofficially designated L C I ( F S ) - Fire Support: L C I ( F S ) - 7 7 - 8 0 , 3 6 5 , 3 6 6 , and 4 3 7 - 4 4 2 . T h e s e boats were armed with 6 x 4 . 5 i n r o c k e t racks each firing 7 2 rockets plus 3 x 4 0 m m , 2 x 2 0 m m , and 5 x . 5 0 c a l guns. Stateside, rocket boats were converted f r o m L C I ( L ) - 3 5 1 class boats and from three L C I ( G ) s , with 3 6 built in t o t a l . A r m a m e n t was the same as the L C I ( M ) , but 6 x 5in rocket launchers replaced the three mortars. T h e craft were fitted with a modified aircraft H 2 C r a d a r to a l l o w t h e m to position themselves precisely. T h e y were also used as radar pickets outside the main fleet area to w a r n o f approaching aircraft. T h e L C I ( R ) had the smallest c r e w o f the fire support L C I s : three officers and 3 1 men. L C I ( R ) s included: 3 1 * , 3 4 % 7 1 * - 7 4 , 2 2 3 - 2 2 6 , 2 3 0 , 3 3 1 , 3 3 7 , 3 3 8 , 340-342, 6 4 2 - 6 5 1 , 704-708, 762-767, 769-772, 1024, 1026, 1028-1030, 1 0 6 8 - 1 0 7 0 , 1 0 7 7 , and 1 0 7 8 . 6

Landing Craft, Infantry (Mortar) In 1 9 4 2 , the US Army Chemical Warfare Service experimented with mounting 4 . 2 i n chemical m o r t a r s on L C I s and L C T s at Amphibious Training Center, Carabelle, F L . T h e " f o u r - d e u c e " m o r t a r was intended to deliver chemical and s m o k e r o u n d s , but since chemical rounds would not be used, high-explosive shells were approved. Able to fire close to shore, the mortars would be able t o continue suppressive fire w h e n the naval and aerial b o m b a r d m e n t s ceased and right up to m o m e n t the assault troops c a m e ashore. T h e m o r t a r induced a heavy recoil and a robust timber frame filled with sand and sawdust was developed to hold the baseplate. T h e first c o m b a t of seaborne mortars saw them mounted on L C T s during the J u l y 1 9 4 3 Sicily landing. It was then decided to modify some LCIs specifically as m o r t a r b o a t s , and they saw their first action during the September 1 9 4 4 Peleliu assault. L C I ( M ) s were subsequently employed in most other landings in the Pacific, as well at N o r m a n d y in J u n e 1 9 4 4 . Forty-two L C I ( M ) s were built, with m a n y being converted from L C I ( G ) s . They possessed a single 4 0 m m gun, four 2 0 m m guns, and three 4.2in mortars (two immediately f o r w a r d o f the deckhouse near the gunwales and another on the centerline further forward. A total of 1 , 2 0 0 x 4 . 2 i n rounds were carried in what had been the N o . 2 troop c o m p a r t m e n t . T h e crew was four officers and 4 9 men. T h e mortar crews were usually trained by US Army chemical mortar battalions and on some boats the mortars were manned by similarly trained Marines. 6 * = Converted from LCI(G).

C o n s t r u c t i o n started at the end o f April 1 9 4 4 and ran through the end of the year. Vessels were built in a r e m a r k a b l y short t i m e , s o m e t i m e s in three w e e k s plus a n o t h e r 2 - 4 w e e k s f o r pre-commission fitting. T h e 1 5 8 f t L C S ( L ) w a s based on the L C I hull, but was greatly reconfigured internally, with an entirely different superstructure and deck a r r a n g e m e n t .

T h e L S M w a s 4 0 f t longer t h a n its LCI troop-carrying counterpart and l i f t broader - 2 0 3 f t 6in long, 3 4 f t 6in beam. Speed though was 2 - 3 knots less than an L C I . It could carry five light or three medium t a n k s , or six amphibious Landing Vehicle, Tracked (LVT) vehicles (better k n o w n as " a m t r a c s " ) , or nine D U K W ( " D u c k " ) a m p h i b i o u s trucks plus 5 4 passengers; later a c c o m m o d a t i o n was for 4 8 passengers. Alternatively, it could carry 1 5 0 tons o f bulk cargo. T h e LVTs and D u c k s could be launched and retrieved at sea via the b o w r a m p . T h e complement was four officers and 4 8 men, later increased to 5 4 m e n . A vehicle well deck ran the entire length, f r o m the double b o w doors and 16ft 2in long r a m p to the stern plate, which could be r e m o v e d . T h i s facility allowed any n u m b e r o f L S M s to be m o o r e d e n d - t o - e n d t o serve as a causeway, allowing vehicles to be driven f r o m LSTs to the b e a c h . T h e deck's width varied. T h e opening to the r a m p was 1 4 f t wide, but then widened out to 2 2 f t 8in for a b o u t a third o f the deck's length and then n a r r o w e d again t o 18ft for almost 9 0 f t . T h e aft-most portion w a s 1 2 f t wide for 1 7 f t . O n either side were high c o m p a r t m e n t e d b u l k h e a d s . O n the p o r t side, f r o m b o w t o stern, were machinery, storage, hospital, galley, engine access hatches, and w o r k s h o p c o m p a r t m e n t s ; the c o m p a r t m e n t s were only 5 - 7 f t wide. O n the well deck's port side in the immediate stern was the stern a n c h o r winch under a platform. T h e b o w a n c h o r was on the f o r w a r d p o r t side. O n the s t a r b o a r d side were machinery, head, w a s h r o o m , heating boiler, and o r d n a n c e stores c o m p a r t m e n t s . Beneath the t a n k deck were ballast t a n k s ; crew, officer and troop quarters; storage, refrigerator and m a c h i n e r y c o m p a r t m e n t s ; engine r o o m , fuel t a n k s , and m o r e t r o o p and storage c o m p a r t m e n t s , with steering

L S M - 1 6 1 w a s the last o f the type in service, finishing its days in 1 9 6 5 as a logistics support ship in the Aleutians: U S S Kodiak. L S M - 5 4 9 a n d 5 5 0 - 5 5 2 w e r e reclassified as salvage lifting vessels ( A R S D - 1 - 4 ) before they were laid down at the war's end. M u c h redesignated, they were c o m m i s s i o n e d in D e c e m b e r 1 9 4 5 as USS Gypsy, Mender, Salvager, and Windlass, respectively. T h e y were decommissioned in the 1 9 4 0 s through the 1 9 6 0 s .

L S M ( R ) vessels were also LSM AND LSM(R) 1 : All LSMs served in the Pacific and while usually painted haze gray with blue decks, including the well deck, they were often painted in green camouflage schemes. While the ideal bow armament was twin 40mm guns, many were armed with a single 40mm on a platform over the ramp compartment and even more had a 20mm tub just abaft the forecastle (see insert). Regardless of the forward armament, all LSMs had two more 20mm guns amidships and two on the fantail. 2: The LSM(R)-188 class was a relatively quick conversion of an LSM to a rocket and gunboat vessel accomplished by decking over the well deck and dividing the interior into numerous compartments. There were two variations of 5in rocket armament. LSM(R)-188-195 had 75 x Mk 36 and 30 x Mk 30 rocket launchers, while LSM(R)-196-199 had 85 x Mk 51 launchers, shown here. Both types had a bow 40mm gun, another forward of the pilothouse, a 5in gun on the fantail, and three 20mm guns. The small elevated tub forward of the 5in gun mounts the fire director. 3: Most 401 class rocket boats were painted a dark gray with a black bottom side. This was a complete redesign, still based on the LSM hull, but it had a completely different superstructure on the stern, with the 5in gun just forward and 10 x twin 5in Mk 102 rocket launchers forward. Other armament included twin 40mms on the bow and fantail, 4 x twin 20mms and 4 x 4.2in mortars, plus two .50cal and two .30cal machine guns. Pacific Fleet 1944 directives stated that the bow and stern quarter hull number of large landing craft and landing ships would be 4ft high. On LCIs and LSMs the stern quarter number height was 4ft, often extending to 6ft. 28

This picture of LSM-32 moored alongside LCI(L)-992 provides an idea of the size difference between the two vessels. They are moored inside ABSD-6, a large auxiliary floating dry dock (ten-section, non-selfpropelled) at Guam.

BELOW LEFT LSM(R)-193 rocket ship with its six-rail Mk 36 and four-rail Mk 30 5in rocket launchers empty. It required 216 hours to reload the second barrage and 4 /2 hours for a subsequent barrage owing to the less convenient stowage, as rockets had to be manhandled to deck through multiple compartments further aft. 1

BELOW RIGHT The differences between the LSM(R)-401 class and the LSM(R)-188 class are apparent. The deckhouse was on the fantail with the 5in gun turret forward and it mounted 10 x 5in automatic-feed Mk 103 twin rocket launchers.

T h e L S M ( R ) - 1 8 8 class retained the L C M ' s s t a r b o a r d superstructure. T h e s e were built b e t w e e n August and O c t o b e r 1 9 4 4 . T h e r e was a single 4 0 m m on the bow, an elevated 4 0 m m tub forward of the pilothouse, a 2 0 m m a b e a m the superstructure on the port side and t w o 2 0 m m s near the stern. A 5 i n ( 3 8 c a l ) gun in a destroyer-type turret w a s m o u n t e d on the fantail. L S M ( R ) - 1 8 8 - 1 9 5 m o u n t e d 7 5 four-rail M k 3 6 and 3 0 six-rail M k 3 0 5in r o c k e t r a c k s . L S M ( R ) - 1 9 6 - 1 9 9 m o u n t e d automatic-feed 5in M k 5 1 rocket launchers and were 4 0 tons heavier. T h e c r e w was five officers and 7 6 men. F o u r o f the 1 2 L S M ( R ) - 1 8 8 class were lost at O k i n a w a . T h e 4 8 L S M ( R ) - 4 0 1 class ships were of a m u c h different arrangement, with the lower deck reconfigured with r o c k e t magazines and a different crew q u a r t e r s l a y o u t . T h i s class included L S M ( R ) - 4 0 1 - 4 1 2 and 5 0 1 - 5 3 6 built b e t w e e n early 1 9 4 5 a n d the summer. T h e last 3 6 o f the 5 0 1 subclass had m i n o r differences f r o m the 4 0 1 class. T h e second deck was also rearranged, with r o c k e t assembly and handling r o o m s and additional crew quarters for the six officers and 1 3 7 m e n . A s o m e w h a t larger centerline deckhouse was

built just f o r w a r d o f the fantail. It held a r a d a r and r o c k e t c o n t r o l r o o m , w a r d r o o m , galley, and mess at main deck level. A b o v e these w a s the radio and chart r o o m , over which was situated the bridge, on t o p o f w h i c h was a tub for a 2 . 5 m optical rangefinder and r o c k e t director. A r m a m e n t was m u c h changed as well, with a twin 4 0 m m on the bow, twin 2 0 m m tubs just t o the aft on either side, plus t w o m o r e o n either side o f the d e c k h o u s e . A 5 i n turreted gun was immediately f o r w a r d of the deckhouse. T h e fantail 5in gun o f the L S M ( R ) - 1 8 8 class required the ship t o turn broadside to shore to fire and so presented a broadside target. M o u n t i n g a 5in forward o f the deckhouse on the L S M ( R ) - 4 0 1 class allowed this to be fired as the vessel advanced t o w a r d shore. M o u n t e d a t o p the w i n c h r o o m o n the fantail was a twin 4 0 m m t u b . F o u r 4 . 2 i n m o r t a r s were provided, t w o forward of the deckhouse and one on either side. T w o . 5 0 c a l m a c h i n e guns were m o u n t e d on the forecastle and t w o . 3 0 c a l m a c h i n e guns on bridge wings. Ten 5in M k 1 0 2 twin a u t o m a t i c r o c k e t launchers were m o u n t e d on the forward deck. T h e goal was to provide an all-purpose fire support vessel with rockets, guns, and m o r t a r s . N o n e saw action in W o r l d W a r II, but they would have been employed for the invasion o f J a p a n . After the war, some L S M ( R ) s were rearmed with twin-tube continuous-feed 5in M k 1 0 5 launchers. T h e s e were fed by a u t o m a t i c hoists with a load o f 3 8 0 improved r o c k e t s , and the m o r t a r s were removed f r o m all the vessels. These modifications allowed the c r e w to be reduced to five officers and 7 6 men. After the w a r m o s t were mothballed. Eight saw service in the K o r e a n War with R o c k e t Division 3 2 - L S M ( R ) - 4 0 1 , 4 0 3 , 4 0 4 , 4 0 9 , 4 1 2 , 5 2 5 , 5 2 7 , and 5 3 6 - and were returned to mothballs after the war. O n O c t o b e r 1 , 1 9 5 5 , the 4 8 remaining ships were named after rivers (exclusive of rivers bearing state names, to prevent confusion with battleships). In 1 9 6 5 L S M ( R ) - 4 0 9 , 5 2 5 , and

5 3 6 were recommissioned - USS Clarion River, Saint Francis River, and White River, respectively - for Vietnam service with Inshore Fire Support Division 9 3 . L S M ( R ) - 4 0 1 , 4 0 4 , 4 0 5 , 4 0 9 , 4 1 2 , 5 1 2 , 5 1 3 , 5 1 5 , 5 2 2 , 5 2 5 , 5 3 1 , and 5 3 6 were reclassified as inshore fire support ships ( L F R ) on J a n u a r y 1 , 1 9 6 9 - a m o o t point as all had been decommissioned by 1 9 7 0 , never to serve again. 31

OPERATIONAL HISTORY L C I s , L S M s , and their fire support variants played important but often unheralded roles in the new form of large-scale amphibious w a r f a r e . LCIs of all types fought in all major theaters. In the Pacific they served from the Aleutian Islands to the Netherlands East Indies, and were prepared to strike at Japan. T h e y operated in far northern waters with the R e d Fleet and in the Mediterranean and English Channel with the US Navy and Royal Navy. Their missions were varied and often dangerous, as can be seen in the summary below. 10

LCI and LSM units

LSM-14 wearing dapplepattern camouflage. Most LSMs had a pair of 20mm guns on the bow. Later ships had a bridged-over forecastle mounting a 40mm gun. With the ramp raised and the doors closed, the space between the ramp and the V-shaped space of the outer doors could be flooded to waterline level and used by the crew for bathing.

Landing vessel units were organized into flotillas, groups, and divisions in descending e c h e l o n s usually c o m m a n d e d by a c a p t a i n , c o m m a n d e r , and lieutenant-commander, respectively. (It was n o t u n c o m m o n for the various c o m m a n d e r s t o be a r a n k l o w e r t h a n t h o s e here given.) An L C I F l o t of 2 4 boats was organized into t w o groups of t w o divisions, each with six boats. As an e x a m p l e , L C I F l o t 4 with L C I ( L ) s 8 3 - 9 6 , 3 1 9 - 3 2 6 , 3 4 9 , and 3 5 0 consisted o f L C I G r p s 7 and 8 with L C I D i v s 1 3 - 1 6 . T h e L C I F l o t 4 flagship was L C I - 8 7 and the t w o L C I G r p flagships were L C I - 8 9 and 3 2 1 . T h e division c o m m a n d e r was simply the senior L C I skipper in each division and had no additional staff. L S M flotillas were organized the same. L C I ( G ) , L C I ( M ) , and L C S ( L ) flotillas had three groups of t w o divisions each, six boats per division for a total o f 3 6 in the flotilla. T h e L C I ( R ) flotilla could be under this organization or have only t w o groups for a total o f 2 4 r o c k e t b o a t s . T h e y usually operated as groups or divisions when conducting fire missions and even in pairs or single ships w h e n patrolling or providing post-landing fire support. H o w L C I s were i n c o r p o r a t e d i n t o the landing force varied f r o m o p e r a t i o n to o p e r a t i o n . T h e flotilla organization was mainly administrative in n a t u r e . W h e n a landing force w a s o r g a n i z e d , L C I flotillas were b r o k e n up and the ships assigned to task groups and task units. Flotilla, group, and division c o m m a n d e r s might be assigned as task group and unit 10 See Osprey Elite 117: US World War II Amphibious Tactics: Pacific Theater and Elite 144: US World War II Amphibious Tactics: European and Mediterranean Theaters.

LCI(R) ROCKET FIRING LCI(G)-73 was first converted to a gunboat and then a rocket boat along with LCI-31 and 34 in the Pacific. She participated in 14 operations, first as a troop-carrier and then as a fire support boat. Here she bears a locally created camouflage scheme. In her early Type F LCI(G) gunboat configuration she mounted more rocket launchers than most rocket boats: 24 x 4.5in Mk 1 racks, each holding 12 rockets. The aft six launchers on each side are being fired in the first barrage about 1,000yd from shore and the forward launchers will be fired a few hundred yards closer to the beach to impact in the same area just behind the dune line. Additional armament included a bow 40mm and three 20mm guns. 32

LCI(L)-1 class boats en route to Normandy with very-lowaltitude (VLA) barrage balloons tethered. After they were moved ashore upon landing, it was found that the Germans used the balloons as artillery aiming points and they were all eventually cut loose.

/I LCIs were notorious for rolling and yawing in even moderate seas, which made them no friend of their passengers. This view is looking forward on an LCI(L)-1 class boat.

c o m m a n d e r s as well as c o m m a n d elements a n d divisions within the task organization, w h i c h might m e a n c o m m a n d i n g other types o f landing craft in the m i x e d o r g a n i z a t i o n , including L S M s , L C T s , and L C M s . Such organizations might be called attack groups, landing and control craft groups, landing craft groups, beach groups (preceded by the beach color designation), assault groups, or reserve groups. As an e x a m p l e , for the Sicily landing, the L i c a t a A t t a c k F o r c e ( T F 8 0 ) c o n t a i n e d the G a f f i A t t a c k G r o u p ( T G 8 6 . 2 ) with 7 x L S T s , 1 5 x L C I s , and 2 1 x L C T s , plus the F a l c o n a r a A t t a c k G r o u p ( T G 8 6 . 5 ) with 1 0 x LSTs, 1 6 x L C I s , and 9 x L C T s . T h e r e were also four other task groups assigned to T F 8 0 with additional LSTs, landing craft, fire support ships, transports, etc. Such groups were divided into waves, with L C I s coming in after the i m m e d i a t e b e a c h h e a d w a s secure to deliver reserve battalions and c o m b a t support units. N o t all missions were c o m b a t assaults. L C I s and L S M s w e r e c o m m o n l y used for various m u n d a n e tasks: shuttling passengers, vehicles, and cargo from base to base; lightering personnel, cargo and vehicles a s h o r e f r o m t r o o p and c a r g o ships; resupplying units as they advanced along the c o a s t ; and simply providing ferry services.

Fire support missions T h e primary mission of L C I gunboats, mortar boats and r o c k e t b o a t s , L C S gunboats, and L S M rocket boats was to provide preparatory and suppressive fire support to amphibious tractor and landing boat groups making the initial assault. T h e y would continue to provide fire support throughout the later phases of an amphibious operation. 34

T h e o p e r a t i o n a l duties o f the fire s u p p o r t vessels during an a m p h i b i o u s landing included: •

•

Protecting the a m t r a c or b o a t group f r o m enemy a u t o m a t i c w e a p o n s fire from the beach and from enemy aircraft while in the rendezvous area, en route to the landing zone, and at the line o f departure. Supporting the landing o f the assault waves with rocket, mortar, and/or automatic weapons fire in order to neutralize the enemy beach defenses. Supporting the troops after landing and during the b o a t shuttle m o v e m e n t by directing fire against e n e m y p o s i t i o n s o n the b e a c h and against enemy aircraft. Laying such smoke screens as may be ordered to hinder enemy observation and fire control, by means of s m o k e rockets and fog generators. Assisting U D T s by covering t h e m with supporting fire or s m o k e (when ordered) in order t o p e r m i t the a c c o m p l i s h m e n t o f r e c o n n a i s s a n c e and demolitions. M a k i n g false demonstrations when ordered, using gunfire, rocket fire, and smoke in order to divert the enemy a w a y f r o m the main landing or m a k e him suspect another landing will occur elsewhere. Performing direct support and harassing missions in support o f the troops after the landing and until the completion o f the operation. This included direct fire support for troops operating along the shore. Providing antiaircraft screens for radar pickets.

• •

Providing " f l y c a t c h e r " screens against suicide boats and swimmers. Performing radar countermeasures, when ordered (when so equipped).

Other missions c o m m o n l y assigned to fire support craft included: search and interdiction patrols for enemy barge traffic attempting resupply, counterlandings, and casualty evacuation; rescuing crews from sinking landing vessels and ships; recovering d o w n e d a i r m e n , b o t h friendly and e n e m y ; patrolling the perimeter o f ship anchorages; conducting reconnaissance patrols up navigable rivers and along remote coastlines; and other odd missions. T h e tactics employed by fire support craft depended on multiple factors: the width of the landing beach; available craft and their types (rocket, gun, m o r t a r ) ; types and dispersion of enemy fortifications; expected enemy

A kamikaze slammed into this LCI(R), but the explosion failed to detonate the hundreds of 5in spin-stabilized rocket warheads. LCIs were not known for their ability to sustain and survive such catastrophic damage. This one was fortunate. 35

Rocket Boat Fire Plan This example of a firing plan for4.5in rocket-armed boats depicts six LCI(R or G) or LSM(R) commencing fire at 2,000yd with 40mm guns, firing ranging rockets at 1,800yd, launching the first salvo set at 45 degrees, elevation at 1,600-1,800yd, the second salvo set at 30 degrees at 1,130yd, and turning to the flanks at 960yd. The Line of Departure is where the amtracs/assault boats assembled. M.P.I. = Mean Point of Impact.

The design, development, operation and history of the machinery of warfare through the ages

LANDING CRAFT, INFANTRY AND FIRE S U P P O R T Described by o n e soldier as "a metal box designed by a sadist to m o v e soldiers across the water,"the Landing Craft, Infantry was a large beaching craft intended to deliver an infantry c o m p a n y to a hostile shore, once the beachhead was secured. The LCI and its vehicle-delivery counterpart, the Landing Ship, M e d i u m were widely used by the Allies during World War II, a n d later, the hulls of these ships were used as the basis for fire s u p p o r t ships. While the landing ships were phased out after the Korean War, s o m e fire support craft remained in use throughout the Vietnam War. This b o o k tells the developmental and operational history of this important tool of American a m p h i b i o u s military strategy that s p a n n e d three wars.
