Family of Heavy Tactical Vehicles

Abstract

This Program Element (PE) aligns system development and demonstration of Heavy Tactical Vehicles (HTV) with Multi-Domain Operations (MDO) requirements to support combat and combat support missions to include line haul, local haul, and unit resupply. HTV trucks transport water, ammunition, and general cargo over all terrains and throughout the battle-space. Systems include the Heavy Expanded Mobility Tactical Truck (HEMTT), Palletized Load System (PLS), Heavy Equipment Transporter System (HETS), Enhanced Heavy Equipment Transporter System (EHETS), Line Haul, Heavy Dump Truck (HDT), medium tactical trailers including the Medium Equipment Trailer (MET), the family of flatbed semitrailers to include but not limited to the 40-Ton M870, 34-Ton M872 and the 25-Ton M172 that support multiple Army missions and the development and demonstration of enablers. Recovery systems such as the Modular Catastrophic Recovery System (MCRS) that rescue large wheeled vehicle platforms in severe off-road conditions are also included. The Common Tactical Truck (CTT) is the next generation of tactical trucks to meet the Army's Tactical Wheeled Vehicle (TWV) Modernization Strategy to take full advantage of economies of scale and commonality with the objective to procure a commercial based Family of Vehicles to replace HEMTT, PLS and Line Haul tractors and leverage best commercial practices at lower procurement costs that are autonomy ready. Periodic evolutionary upgrade of survivability and crew protection as described in the Long Term Protection Strategy (LTPS) is supported by this PE for both the HTV family of vehicles and the Family of Medium Tactical Vehicles (FMTV). The Tactical Wheeled Vehicle - Leader Follower (TWV-LF) program provides transportation units with the capability for Tactical Wheeled Vehicles (TWVs) to operate in an unmanned mode, initially for the Palletized Loading System (PLS) vehicles, while operating in a convoy. This is accomplished by integrating technology to the PLS vehicles which enables them to follow a manned leader or unmanned follower vehicle. This is done in a March Unit of up to (10 - squad length) TWVs, with (1) manned Lead vehicle and up to (9) unmanned Follower vehicles. This capability provides increased Soldier Force Protection and increased convoy logistics throughput by giving Commanders more options on Soldier utilization, removing Soldiers from threat zones and/or utilizing vehicle operators for convoy security, and allowing supply convoys to run more often. The PLSA1 is the initial tactical vehicle used to support By-Wire Active Safety which provides the foundation for autonomous capabilities such as Leader/Follower taking Soldiers out of harm's way. Funding also supports modernization of the current Tactical Wheeled Vehicle fleets by investigating technology insertions including, but not limited to: predictive based maintenance, vetronics, Victory Architecture, vehicle electrification, autonomous operations and other emerging technologies. Funding also supports developing initial prototypes to enable refinement of Operational Requirements and early user feedback to support future sustainment and operational movement operating concepts. In accordance with Section 1815 of the FY 2008 National Defense Authorization Act (P.L. 110-181), this item is necessary for use by the active and reserve components of the Armed Forces for homeland defense missions, domestic emergency responses, and providing military support to civil authorities.

• Change Summary Explanation: FY 2022 increase of $19.108 million covers EHETS Developmental and Operational Test requirements and test of MET prototypes between two vendors. It also starts acquisition planning and analysis for the Common Tactical Truck modernization effort. Additionally, the TWF-LF program effort is continued through extension of Operational Technology Demonstration (OTD) to further mature software and design. These efforts align program requirements with Army modernization priorities in support of the National Defense Strategy.
