LVTP-X2 Prototype on trials 1952-54- SRC snafu-solomon
Development of the LVTP-6The latter was the rival project designed by the BorgWarner company in 1947. It had some engine modifications plus four types of transmissions tested as a total of five prototypes were produced. The LVTP-X2 (I) had a Cadillac Co. Model331 V-type 8-cylinder engine (187.5 hp). The LVTP-X2 (II) had the same GMC Inc. Model 302 series six-cylinder engine as the M59 prototype (127 horsepower, 3,350 rev/146 hp/3,600 rotation) which equipped with prototypes of the 2 groups. Only two have been manufactured. The LVTP-X2 (III) wad given the Chrysler Corp. V-type 8-cylinder engine (197 hp) and another of the same serie tested the Chrysler "Powerflyte" automatic transmission. The LVTP-X2 (III-2) had the Chrysler Corp. V8 (197 hp) which was eventually selected for mass production vehicle and became the LVTP-6. The LVTP-X2 (III) was also given the same General Motors FS-301MG automatic transmission than the M59 prototype. The LVTP-6 will eventually be FMC's unsuccessful paralleled development for Borg-Warner's LVTP-5 Based on the Army M59 APC, but never entered mass production.
The LVTP-6The LVT-6 developed by Borg Warner, part of Ingersoll (Ingersoll), Inc. was a crawler-type amphibious armored vehicle, prototype first completed by 1951. FMC Corporation's more compact model was as described on the tests and eval reports "there was a need for an inexpensive amphibious instrumentation". This Development led to the LVTP-X2, medium weight Amtrac. This became its provisional name, was offered again for trials. The Marine Corps also instructed the "LVTP-X2" development should continue. Its basis, the T59, became the prototype of the M59 armored personnel carrier. Various engines were tested from 1952 ended with a Chrysler engine, selected for production. The same Chrysler prototype also had good mobility and better seaworthiness compared to lumbering LVTP-5. It was stable in waves up to 10 feet high, and motricity on slopes was excellent.
Fire support version SRC
Further evaluations preconised the adoption of the "LVT-6" whereas was initiated the development variants. The basic troop transport in 1956 was at last adopted as the LVTP-6, whereas the LVTP-5 was just gaining mass production. However when the much improved LVTP-5A1 was ready for production, the Marine Corps staff concluded that there was no need for two models, and the LVTP-6 production was never started, ordered never came; Development was aborted, however it was further developed into the fire support type LVTH-X4, and prototype for the surface-to-air carrier LVTAA-X2, another cancelled program. The LVTH-X4 ptototypes were kept since at the California-based San Bernardino group of same name County, and in Barstow City, at the United States Marine Corps Barstow Depot (Marine Corps Logistics Base Barstow).
