The Landing Craft Infantry (LCI) were several classes of seagoing amphibious assault ships of the Second World War used to land large numbers of infantry directly onto beaches. They were developed in response to a British request for a vessel capable of carrying and landing substantially more troops than their smaller Landing Craft Assault (LCA). The result was a small steel ship that could land 200 troops, traveling from rear bases on its own bottom at a speed of up to 15 knots. Some 923 were built starting in 1943, serving in both the Pacific and European theaters, including a number that were converted into heavily armed beach assault support ships. Commonly called "Elsie Items," the LCI(L) supplemented the small LCAs/LCVPs as a way to get many troops ashore before a dock could be captured or built. As such, they were the largest dedicated beachable infantry landing craft (the larger Landing Ship Infantry (LSI) was a transporter for troops and small craft such as the British LCA) in the allied inventory.

Development[edit | edit source]
The LCI(L) was designed to carry 200 troops at up to 15 knots and be as capable at landing as the LCA. Since a steel hull would be needed and steel was already earmarked for building destroyers at home the U.S was approached. There the plans were developed into the LCI(L) - Landing Craft Infantry (Large). The original British design was envisioned as being a "one time use" vessel which would simply ferry the troops across the English Channel, and were considered an expendable vessel. As such, no troop sleeping accommodations were placed in the original design. The troops were provided benches (similar to a ferry) upon which to sit while they were transported across the channel. This was changed shortly after initial use of these ships, when it was discovered that many missions would require overnight accommodations. The US was able to come up with an easily-built and mass-produced design by using non-traditional shipbuilding facilities and equipment. The US established LCI building yards at ten different locations.
Construction[edit | edit source]
There were 3 major types of LCI(L) which differed mostly by the location of the ramps and by the shape of the conning tower. All of these ships had similar hulls. The hull of all LCI(L) were 158 ft (48 m) long with a 23 foot beam, making them relatively long and narrow. All LCI(L) were similarly powered with two Detroit Diesel 6-71 "Quad" Diesel Engines. These engines were a wartime expedient design that utilized existing and readily available engines (GM 6-71) adapted to create a propulsion source. Each propeller shaft was powered by 4 engines joined together using individual drive clutches hence the name "Quad Diesel". If a single engine were to fail, the broken engine could be disconnected from the unit via its clutch and repaired while still operating the other 3 engines. Each of the two propellers was a reversible pitch propeller, which allowed the propeller shaft to spin only in one direction for either ahead or astern operation. This, coupled with the use of a stern anchor which was dropped as the ship approached the beach, was used to pull the ship off the beach after the troops had disembarked.
The 3 major LCI(L) types are normally referred to as: a) Square Conning tower, Side Ramp (the original style) b) Round Conn, Side Ramp c) Round Conn, Bow Ramp
On LCI(L)1-349 class, (Square Conn, Side Ramps) the deck was wider than the prow and two gangways on either side of the bow led onto a pair of ramps that were lowered, and down which troops would disembark. The LCI 350 class had a single enclosed bow ramp with 2 bow doors that swung open. The reason for moving the ramp to the inside was to provide some protection for the troops as they disembarked to the beach, if only by concealing them from enemy sight. Also, the low, squared-off conning tower was upgraded on later models (LCI(L)350 and higher) with a taller, round conning tower which afforded slightly more visibility from the bridge.
The steepness and narrowness of either type of bow ramps made the LCI impractical for landing troops as part of an initial assault against a defended beach, and they were sometimes reserved for the follow-up waves, after the LCA or LCPL boats had landed. However, they were included in the first waves at numerous invasions such as Anzio, Normandy, Southern France, Elba, Saipan, the Philippines, Iwo Jima, Guam, and Okinawa.
Armament[edit | edit source]
LCI(L) were armed originally with four to five 20mm Oerlikon automatic cannons. Each gun was mounted inside of a round gun tub with an integral splinter shield. As the war progressed, several LCI(L) were modified into LCI Gunboats. These gunboats, called LCI(G) had three of their forward mounted 20mm Oerlikon cannons removed and replaced with heavier single barrel 40mm Bofors cannons. Also, several LCI(L) had various types of Rocket Launcher racks added in place of their side ramps and inside their well decks. These ships were sometimes designated as LCI(R) for Rocket Ships. Still other LCI(L) were modified to carry three 4.2 inch Heavy Mortars. These were designated as LCI(M).
Service history[edit | edit source]
The first LCI(L)s entered service in 1943 chiefly with the Royal Navy (RN) and United States Navy. Early models were capable of carrying 180 troops, this was increased to 210 later. Craft in service with the two navies had some variation according to national preferences. Some 923 LCI were built in ten American shipyards and 211 provided under lend-lease to the Royal Navy. In Royal Navy service they were known as "HM LCI(L)-(pennant number)". During Project Hula, the United States in June and July 1945 secretly transferred 30 LCI(L)s to the Soviet Navy, which designated the type as desantiye suda ("landing ship") or DS; they saw action against the Japanese after the Soviet Union entered the war against Japan in August 1945, and five – DS-1 (ex-USS LCI(L)-672), DS-5 (ex-USS LCI(L)-525), DS-9 (ex-USS LCI(L)-554), DS-43 (ex-USS LCI(L)-943), and DS-47 (ex-USS LCI(L)-671) – out of 16 involved were lost on 18 August 1945 during the landings on Shumshu. The Soviet Union eventually returned 15 of the surviving LCI(L)s to the United States, all in 1955.
In use, the LCI fleet was used for numerous missions. One important use was for smoke laying to obscure the invading fleet from enemy artillery or aircraft. Still others were used to provide close-in gunfire support to the troops who had just landed on the beach. In one such episode, eight LCI(G) were used two days prior to the invasion of Iwo Jima to protect Underwater Demolition Team insertion and beach mapping teams. They were mistaken by the Japanese defenders as the main invasion, and were fired upon by numerous previously hidden large caliber coastal defense artillery, (up to 8 inch). Three of these LCI(G) were sunk and all were damaged. Lt.(j.g) Rufus G. Herring (CO LCI Force) received the Medal of Honor for this action.
In another instance, Lt. Alec Guinness RNVR made numerous trips as the Commanding Officer of HMS LCI(L)-124 delivering troops to the beach near Cape Passero lighthouse on 9 July 1943 during the Allied invasion of Sicily. He missed the call from his commander to delay the landing and went on to land 25 minutes ahead of the rest of the LCI Flotilla. As he was returning from the beach empty, he was rebuked by his Flotilla Commander, who thought he was deserting from the fight, when he informed the Commander he was on his way back to get more troops after having already landed once.
Most LCI(L)s were struck from service by both the Royal Navy and the U.S. Naby in 1946, and were put into reserve, sold, scrapped, or used as target ships. In addition to the 30 LCI(L)s, transferred to the Soviet Union in Project Hula, the United States also transferred LCI(L)s to Argentina (15), the Republic of China (13), France (14), Indonesia (7), Chile (6), the Dominican Republic (3), the Philippines (3), Israel (2), Thailand (2), and the Republic of Korea (1).
In February 1949, the U.S. reclassified the remaining LCIs as "Landing Ship Infantry" (LSI). Landing Ship Infantry was a term that had been used during the war since around 1941 by the British for various vessels such as converted ferries and passenger ships that could carry 800–1,800 troops close to shore, the final transfer being by smaller boats.
Variants[edit | edit source]
As with the Landing craft tank, the LCI(L) was used as the basis of a number of conversions into specialist vessels.
LC(FF) - Flotilla flagship[edit | edit source]
Equipped to carry flag officers and crew.
LCI(G) - Gunboat[edit | edit source]
Two or sometimes three 40 mm guns, six .50-caliber (12.7mm) machine guns and ten Mk.7 rocket launchers were added to the existing armament to provide close-in fire support for landings. This variant was used for the basis of the LCS(L) class of Landing Craft Support ships. The same hull was used and more armament was added, but the troop carrying capability was removed.
LCI(M) - Mortar[edit | edit source]
Equipped with a dismountable 4.2 in mortar for naval use and amphibious deployment.
LCI(R) - Rocket[edit | edit source]
A platform for six 5-inch rocket launchers. This platform was rather unsophisticated as the rocket launchers were fixed to the deck, and so the ship had to be maneuvered to aim them. When fired the crew had to take shelter below decks to escape the blast of the rocket engines.
Fairmile Type H landing craft[edit | edit source]
LCI(S)[edit | edit source]
At the same time as the LCI(L) was handed over for US development and production, the British reworked their need for a raiding vessel into something that could be produced natively without making demands on limited resources. Fairmile Marine had already designed a number of small military vessels that were built in wood and they produced the Fairmile Type H which was another prefabricated wooden design. This was taken on as the Landing Craft Infantry (Small) or LCI(S). One Fairmile "H" still survives a veteran of D-Day and the costly assault on Walcheren, it is a houseboat on the River Adur, Shoreham by sea West Sussex,England.
LCS(L)[edit | edit source]
The Landing Craft Support (Large) ("LCS(L) Mark 1" or "LCS(L) Mark 2") was based on the LCI(S) hull, and were built by the United Kingdom, intended for use as a support vessel providing additional firepower. The Mk.1 carried a tank turret complete with its QF 2 pounder gun (40 mm), but for the Mk.2 this was replaced with a turret mounting the QF 6 pounder gun (57 mm). To this was added two Oerlikon 20 mm cannon and two 0.5 inch Vickers machine guns. Ten were built in all.
LCS(L) Mk.3/LSSL[edit | edit source]
The Landing Craft Support (Large) or "LCS(L) Mark 3" was built by the United States. These ships were built on a standard LCI hull, but were modified to add gunfire support equipment and accommodation. They were armed with a single 3"/50 caliber gun and/or two twin 40 mm cannon and numerous 20 mm cannon. These ships were prevalent in most major Pacific Theater invasions beginning in late 1944. The type was reclassified as Landing Ship Support, Large (LSSL) in 1949. One hundred and thirty of this type were built.
Surviving LCIs[edit | edit source]
There are several LCIs that still survive and are available to be seen by the public.
The LCI(L)-713, (a round conn, bow ramp) is located in Portland, Oregon near the I-5 Bridge over the Columbia River. It is currently owned and being restored by a non-profit 501c3 group, the "Amphibious Forces Memorial Museum". Built in 1944 in Neponset, Massachusetts, the ship was transferred to the Pacific Theatre where it saw action in making two assault landings: Zamboanga, Philippines in March 1945 and Brunei Bay, Borneo in June 1945 (as part of the Battle of North Borneo). Purchased as war surplus initially for use as a log hauling tugboat, the engines were removed and it was relegated to a floating storage hulk in Stephenson WA until the late 1950s when it was abandoned and sank into the river mud on the shore of the Columbia river. In the late 1970s the ship was refloated and restoration began on the ship. LCI(L)713 has changed ownership until finally sold to the AFMM in 2003. The LCI(L) 713 has been continually restored with the goal of becoming a historically correct operating museum vessel. Another survivor is LCI(L)-1091 (also a round conn, bow ramp). Moored in Eureka, California, she is owned and operated by the Humboldt Bay Air & Sea Museum. The ship was used in the Korean War in 1951-1953 as an "Infectious Disease Control Ship". Her interior was modified to accommodate a larger crew that included ten Medical Doctors and Lab Technicians. In the late 1950s the ship was sold as surplus for use as an Alaskan fishing vessel. 30 years later, the 1091 was purchased and brought to Eureka, California, in the 1990s by Ralph "Doc" Davis for use as a private fishing vessel. Doc Davis sold the ship to the museum, headed by Mr Leroy Marsh, and they are working together to restore the LCI-1091 to an operating museum vessel.
Several former LCI hulls were obtained and modified for use as sightseeing vessels after World War II by the New York City "Circle Line". The Circle Line 7 (ex-LCI-191), Circle Line 8 (ex-LCI 179) are all now retired. Circle Line X is currently on active duty with Circle Line 42nd Street on New York City's Pier 83.
Several other LCI hulls have been located around the world. The Argentine Navy has at least three, which were being used as of 1998. The ex LCI(L)-653, renamed Husky II, was used as a pilot boat and then a fisheries tender in Alaska before being broken up at Homer, Alaska in 2010. Three derelict LCI hulls remain at Staten Island, New York, in the Witte Marine salvage yard.
Only one LCS(L) Mk.3, the former LCS-102, still survives in original configuration. She is moored at Mare Island, California, where she is being restored to her WWII appearance by volunteers.
