Family of Heavy Tactical Vehicles

Mission — Family Of Hvy Tac Veh source

No mission requirements for Project 659 in FY 2025 and FY 2026. Funds were transferred to Project DG7 / Common Tactical Truck, for execution. In accordance with Section 1815 of the FY 2008 National Defense Authorization Act (P.L. 110-181), these items are 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.

Mission — Family of Heavy Tactical Vehicles source

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) and other heavy wreckers, that rescue large wheeled and track vehicle platforms in severe off-road conditions are also included. 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). Arctic and Demand Reduction Initiatives are also supported by this PE. The Common Tactical Truck (CTT) program is a Family of Vehicles (FoV) that will replace the M915 Line Haul Tractor (LHT), Palletized Load System (PLS), and Heavy Expanded Mobility Tactical Truck (HEMTT) by leveraging best commercial practices and mature commercially available technology, including Predictive Logistics, Advanced Driver Assistance Systems (ADAS), and autonomy ready, resulting in lower procurement costs through economies of scale. The FY 2026 cost of the Common Tactical Truck (CTT) Middle Tier of Acquisition effort is $11.3 million, including RDT&E and procurement of prototype units. The Department will certify FYDP funding in a future budget submission. The Leader Follower (LF) funding line supports the Autonomous Transport Vehicle-System (ATV-S) effort that equips Tactical Wheeled Vehicles with autonomous behaviors. Additionally, the capability gives convoy commanders flexibility to leverage the six levels of automated driving that range from Level 0 (Fully Manual) to Level 5 (Fully Autonomous), and any combination therein to conduct convoy operations. Autonomous driving behaviors enable increased operational efficiency of tactical wheeled vehicles resulting in an increase of sustainment throughput while reducing Soldier exposure to hostile threats. The FY 2026 cost of the Autonomous Transport Vehicle-System (ATV-S) Middle Tier of Acquisition effort is $16.8 million, including RDT&E and procurement of prototype units. The Department will certify FYDP funding in a future budget submission. 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. The FY 2026 request was reduced by $0.277 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative." The FY 2026 request was reduced by $0.209 million for civilian personnel to optimize the workforce in compliance with Executive Order 14210, "Implementing the President's Department of Government Efficiency Workforce Optimization Initiative."
