AM General
In 1979, AM General began preliminary design work on the M998 Series High Mobility Multi-Purpose Wheeled Vehicle (HMMWV, pronounced Humvee), a 1.25-ton truck intended to replace the M151 and other Light Utility Vehicles. The US Army awarded AM General a prototype contract in 1981 with development and operational testing conducted over a five-month period in 1982. In March 1983, AM General won an initial $1.2 billion contract to produce 55,000 Humvees to be delivered in five basic models and 15 different configurations over a five-year period.
