AM General receives a contract from the Pentagon to develop the high-mobility multipurpose wheeled vehicle, or HMMWV, on March 22, 1983.
Nicknamed the Humvee and designed to transport troops and cargo, the wide, rugged vehicle gained fame when it was used by U.S. military personnel during the 1989 invasion of Panama and the Persian Gulf War in the early 1990s.
The initial contract was worth $1.2 billion for 55,000 Humvees.
The Humvees were to be delivered in five basic models and 15 configurations over five years.
The U.S. Army later increased the order to 70,000 Humvees valued at $1.6 billion.
Preliminary design work for the Humvee began in 1979 and in 1981, the Army awarded AM General a prototype contract. The development and operational testing took place over five months in 1982.
