Alligators. The initial 200 LVTs were built at FMC's factory in Dunedin, Florida, where most of the improvement work had been done as well. The first production LVT rolled out of the plant in July, 1941. Later, wartime LVT production was expanded by FMC and the Navy to four factories, including the initial facility in Dunedin; the new facilities were located in Lakeland, Florida, Riverside, California, and San Jose, California. The LVT-1 could carry 18 fully equipped men or of cargo. Originally intended to carry replenishment from ships to shore, they lacked armor protection and their tracks and suspension were unreliable when used on hard terrain. However, the Marines soon recognized the potential of the LVT as an assault vehicle. A battalion of LVTs was ready for 1st Marine Division by 16 February 1942. The LVTs saw their first operational use in Guadalcanal, where they were used exclusively for landing supplies. About 128 LVTs were available for the landings. LVT-2 Buffalo and other developments As early as January 1940, Roebling had prepared preliminary sketches of an LVT with a gun turret to provide fire support to the landing waves. The concept languished until June 1941, when USMC recommended development of an LVT armed with a 37mm gun and three machine guns and armored against 0.50 (12.7mm) machine gun fire. Development was slow and ultimately involved a complete redesign of the LVT, the LVT-2 Buffalo. Armored versions were introduced as well as fire support versions, dubbed Amtanks, which were fitted with turrets from Stuart series light tanks (LVT(A)-1) and Howitzer Motor Carriage M8s (LVT(A)-4). Among other upgrades were a new powerpack (engine and cooling accessories), also borrowed from the Stuarts, and a rubber "torsilastic" suspension which improved performance on land. After Borg-Warner evaluated the LVT-1, Borg-Warner and FMC began work on new designs. FMC was assisted by faculty from Caltech and the University of California and developed the designs that became the LVT-2 and the LVT(A)-1. Interest in the LVT was enough that the Secretary of the Navy formed the Continued Board for the Development of the Landing Vehicle Tracked on 30 October 1943. Production continued throughout the war, resulting in 18,616 LVTs delivered. 23 US Army and 11 USMC battalions were equipped by 1945 with LVTs. British and Australian armies also used LVTs in combat during World War II. In the late 1940s, a series of prototypes were built and
