Future Tactical Truck System

M939 series of 2.5 and 5 ton trucks. The FTTS-UV (Utility Vehicle) was to replace the HMMWV, while the FTTS-MSV (Manoeuvre Sustainment Vehicle) was to replace all other types.^[1]

Future Combat System (FCS)) with just two variants would eventually replace virtually all of the current tactical wheeled vehicle fleet. In a more realistic approach, the current FTTS-MSV/UV Advanced Concept Technology Demonstration (ACTD) efforts (with input from other efforts) will now be used ‘to define requirements’ for future U.S.

pdf stated that the ACTD for FTTS was taking a two phase approach; the first phase involved modeling and simulation (M&S) efforts in which multiple vendors presented concepts for technologies to be incorporated into designs for the UV and MSV variants of FTTS. The second phase included awards to three of the M&S contractors to manufacture prototype designs: two contractors to produce their UV version with trailer, and one contractor to produce two MSVs with companion trailers. All vehicles and trailers were to be evaluated in a Military Utility Assessment (MUA) at Fort Lewis
