AM General has received a $126.5 million contract modification from the U.S. Army for continued production of the M1165A1B3 High Mobility Multipurpose Wheeled Vehicle (HMMWV), or Humvee, according to a Department of Defense announcement.
The modification increases the total contract value to just over $3.05 billion.
The contract, identified as modification P00023 to contract W912CH-24-F-0229, funds additional deliveries of the upgraded M1165A1B3 variant. The work will be performed at AM General’s facility in South Bend, Indiana, and is expected to be completed by August 28, 2027.
Army Contracting Command at Detroit Arsenal, Michigan, is overseeing the acquisition. Fiscal Year 2025 procurement funding in the full amount of $126,531,778 was obligated at the time of award. The contract was formally awarded on June 28, 2025.
The M1165A1B3 is a mission-configurable variant of the Army’s long-serving HMMWV platform, designed for command and control, communications, and general transport missions in forward-deployed environments. According to Army documentation, this variant includes a 30,000 BTU air conditioning system, as well as the B3 armor kit, which features perimeter armor, overhead protection, and a rear ballistic bulkhead.
The modular armor configuration allows field units to tailor the vehicle’s protection level based on mission threat assessments. Depending on the selected armor and fragmentation kit, the M1165A1B3 can carry payloads ranging from 2,230 to 4,950 pounds.
The vehicle is also fully compatible with Army mobility and deployment requirements. The M1165 is both air transportable and airdroppable, and it can be sling-loaded by helicopter, allowing rapid forward deployment in expeditionary operations.
AM General, based in Indiana, has been the primary HMMWV manufacturer since the vehicle’s initial adoption in the 1980s. Though the Army has moved toward newer platforms like the Joint Light Tactical Vehicle (JLTV), the HMMWV remains in widespread use across the force and with U.S. allies, particularly in configurations adapted for command, reconnaissance, and light logistics.
