The Landing Craft, Mechanized Mark 2 or LCM (2) was a landing craft used for amphibious landings early in the United States' involvement in the Second World War. Though its primary purpose was to transport light tanks from ships to enemy-held shores, it was also used to carry guns and stores. The craft was designed by the Navy's Bureau of Construction and Repair and the initial production contract was let to the American Car & Foundry Company. A total of 147 were built by this company and Higgins Industries. Because of its light load capacity and the rapid production of the superseding LCM (3), the LCM (2) quickly fell out of use following the Allied invasion of North Africa in 1942.

Constructed of steel, this shallow-draft, barge-like boat could ferry a small armored vehicle to shore at 7.5 knots (17 km/h). The craft was generally carried on the deck of a transport ship and then lowered into the water, a few miles from its objective, by crane or derrick. The cargo was then placed into the craft by crane or derrick. Once the LCM (2) had touched down on shore, the hinged ramp at the bow of the craft was lowered and the tank left the craft over the ramp under its own power.

Origins
As early as 1930, the United States Marine Corps was interested in landing tankettes on beaches along with assaulting infantry. By the mid-1930s, Marine planners had settled on a beach assault procedure that involved a purpose built craft for the initial assault wave, ships' boats and cutters for follow-on troops, and a purpose built tank lighter for vehicles, guns, and supplies.[1] Nevertheless, progress was difficult and slow due to lack of funding. Also, the Navy placed restrictions on such craft – considering transportation and deployment of them from available ships.[nb 1] By 1940, prototypes, of 38-foot to 40-foot long vessels,[2] had been built and tested. The positive attributes of these were recognized and, by September 1940, the USMC had made known their requirements for a tank landing craft. The Navy's Bureau of Construction and Repair produced a 45-foot lighter capable of carrying the 15 ton Army model tank the Marines anticipated using.[3] What evolved became the LCM (2),[4] although at the time it was referred to using the Marine Corps designation of YL.[5][nb 2]

Service history

The war time US Navy publication Allied Landing Craft and Ships describes the operational use of the LCM (2) as "To land one light tank or motor vehicle."[6]
In early August 1942, when the US Navy expedition arrived at Guadalcanal, it contained 48 LCM (2)s; almost the Navy's entire inventory of LCMs.[7] The force also had a small assortment of earlier designs of barges and ponts, plus 116 Landing Craft Vehicle (LCV)s, each able to hold 10,000-pounds of cargo,[8] such as a 75 mm pack howitzer, a 105 mm howitzer, or 1-ton truck, but heavier equipment (90 mm and 5-inch guns, heavy trucks, and the Marines' tanks) would have to be carried in the LCM (2)s.[9]
In early November 1942, these craft operated with the Western Task Force, landing in the Casablanca area during Operation Torch. In July 1943, they saw limited service during the Sicily landings and a few still served as late as the Salerno landings in September 1943.[10]
