HitchAI read

U.S. Army requests $43.0M in FY2027 — the program's peak. In the FY2027 defense authorization, the House funded it in full; the Senate added 23% (to $53.0M); House appropriators funded it in full. TACOM LCMP leads the industry work, though an unusually large share flows to government labs and warfare centers.

Program detail

Mission & acquisition strategy

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.

The Leader Follower (Autonomous Transport Vehicle-System (ATV-S) program) strategy utilizes the Middle Tier of Acquisition (MTA) Rapid Prototyping pathway to compete multiple contractor solutions through a three phased competitive selection process. Phase 1 concluded with the evaluation of the three contractor solutions through a demonstration event and transitioned to Phase 2 with two vendors selected to continue into performance test and evaluation. The ATV-S program has entered Phase 2, Prototype Testing and Operational Demonstration with two awarded contractors.

What project EZ8 buys

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 total cost of the Autonomous Transport Vehicle-System (ATV-S) Middle Tier of Acquisition Rapid Prototyping (MTA-RP) effort is $93.214 million from FY 2023 to FY 2027. The ATV-S MTA-RP program is fully funded across the Future Years Defense Program. FY 2027 RDTE in the amount of $22.232 million funds Phase 3 contract milestone completion of prototypes in support of First Unit Issued (FUI), technical support, software development and program support.

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 Initiatives are also supported by this PE. Funding supports modernization of the current Tactical Wheeled Vehicle fleets by investigating technology insertions including, but not limited to: Predictive Logistics, vetronics, transportability of tactical wheeled vehicle equipment, vehicle electrification, fully 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), 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.
