Future Tactical Truck System

The Future Tactical Truck System (FTTS) was a United States Armed Forces program for which the Operational Requirements Document was drawn up during 2003. FTTS was a proposed two vehicle modular family that was to replace the AM General High Mobility Multipurpose Wheeled Vehicle (HMMWV (the Humvee)), Family of Medium Tactical Vehicles (FMTV), Oshkosh M977 Heavy Expanded Mobility Tactical Truck (HEMTT), Palletized Load System (PLS) (in certain echelons), and all remaining M35, M809 and M939 series of 2.5 and 5 ton trucks.
