Print Friendly, PDF & Email


The High Mobility Multipurpose Wheeled Vehicle (HMMWV) is a lightweight, highly mobile, high-performance, diesel-powered four-wheel drive, air-transportable and air-droppable family of tactical vehicles. The HMMWV supports combat and combat service support units with a versatile, mission-configurable, tactical wheeled vehicle.

The Army recognizes the tactical importance of the HMMWV fleet and the enduring requirement to maintain a relevant, capable fleet to support the Army enterprise. Congressional funding has enabled the modernization of the U.S. Army National Guard (NG) and Reserve HMMWV fleets.

The NG and Reserve modernization program consists of recapitalizing M1152A1 and M1165A1 Up-Armored HMMWV (UAH) Shelter and Troop Carriers; converting M1151A1 UAH Armament Carriers to M1167 UAH Tube-Launched, Optically Tracked, Wireless-Guided Missile Carriers; and purchasing new M997A3 ambulances. The recapitalization efforts involve a Public-Private Partnership (PPP) between AM General and the Red River Army Depot (RRAD). The M997A3 effort is a joint effort with the chassis built by AM General and furnished to Rock Island Arsenal (RIA) for installation of an RIA-built box.


With configurations to meet multiple mission types and roles, the HMMWV is well-suited to meet the needs of Soldiers in several situations. Its high power-to-weight ratio, high ground clearance and four-wheel drive are designed for agility and mobility in difficult terrain.
