Humvee
The High Mobility Multipurpose Wheeled Vehicle (HMMWV; colloquial: Humvee) is a family of light, four-wheel drive military trucks and utility vehicles produced by AM General. It has largely supplanted the roles previously performed by the original jeep, and others such as the Vietnam War-era M151 Jeep, the M561 "Gama Goat", their M718A1 and M792 ambulance versions, the Commercial Utility Cargo Vehicle, and other light trucks. Primarily used by the United States military, it is also used by numerous other countries and organizations and even in civilian adaptations.
The Humvee saw widespread use in the Gulf War of 1991, where it navigated the desert terrain; this usage helped to inspire civilian Hummer versions. The vehicle's original unarmored design was later seen to be inadequate and was found to be particularly vulnerable to improvised explosive devices in the Iraq War. The U.S. hastily up-armored select models and replaced frontline units with the MRAP. Under the Joint Light Tactical Vehicle (JLTV) program, in 2015 the U.S. Army selected the Oshkosh L-ATV to replace the vehicle in frontline U.S. military service.
Since World War II, the "Willys MB 1⁄4-ton Truck, Command and Reconnaissance", and its evolutions, were used for mass-deployment, and became known as "jeeps". The United States military had continued to rely heavily on jeeps as general utility vehicles and as a mass-transport for soldiers in small groups. Although the U.S. Army had let Ford redesign the jeep from the ground up during the 1950s, and the resulting 1960 Ford M151 jeep incorporated significant innovations, it firmly adhered to the original concept: a very compact, light enough to manhandle, low profile vehicle, with a folding windshield, that a layman could barely distinguish from the preceding Willys jeeps. The jeeps were more than two feet shorter than a Volkswagen Beetle and weighed just over one metric ton, seating three to four, with a 800 lb (360 kg) off-road payload rating. During and after the war, the very light, 1⁄4-ton jeeps were complemented by the 3⁄4-ton Dodge WC and Korean War Dodge M37 models.[citation needed]
By the mid-1960s, the U.S. military felt a need to reevaluate their aging light vehicle fleet. From the mid-1960s, the U.S. Army had tried to modernize, through replacing the larger, purpose-built Dodge M37s by militarized, "commercial off the shelf" (COTS) 4×4 trucks — initially the M715 Jeep trucks, succeeded in the later 1970s by several "CUCV" adapted commercial pickup series, but these did not satisfy newer requirements either. What was wanted was a truly versatile light military truck, that could replace multiple outdated vehicles. When becoming aware of the U.S. Army's desire for a versatile new light weapons carrier/reconnaissance vehicle, as early as 1969 FMC Corporation started development on their XR311 prototype and offered it for testing in 1970. At least a dozen of these were built for testing under the High Mobility Combat Vehicle, or HMCV program, initially much more as an enhanced capability successor to the M151 jeep, than as a general-purpose vehicle.[citation needed]
The HMMWV program had its origins in the Combat Support Vehicle (CSV) program. The XM966 CSV was a proposed platform for the TOW missile launcher. Congress ended the program in 1977 due to the relatively small requirement of 3,800 vehicles. Adjusting to Congress's expectations, the Army increased the scale of the program, then called the XM966 High Mobility Weapons Carrier (CSVP), to replace multiple other trucks. Congress, interested in a larger joint services truck program, removed the CSVP from the 1979 budget. The Army restructured the program, which was then called High Mobility Multipurpose Wheeled Vehicle.
In 1979, the U.S. Army released draft specifications for the High Mobility Multipurpose Wheeled Vehicle (HMMWV), which was to replace all U.S. Army tactical vehicles in the 1/4-ton to 5/4-ton range, As well as select vehicles in the U.S. Marine Corps and U.S. Air Force. Namely these were the M151 quarter-ton jeeps, M561 Gama Goats, and the CUCVs, as one uniform "jack-of-all-trades" light tactical vehicle series, to better perform the roles of the impractically mixed fleet of outdated existing vehicles.[unreliable source?] The specifications called for a diesel engine, excellent on and off-road performance, the ability to carry a large payload, and improved survivability against indirect fire. Compared to the jeep, it was larger and had a much wider track, with a 16 in (410 mm) ground clearance, double that of most sport-utility vehicles. The new truck was to climb a 60 percent incline and traverse a 40 percent slope and ford 5 ft (1.5 m) of water and electronics waterproofed to drive through 2.5 ft (0.76 m) of water were specified. The radiator was to be mounted high, sloping over the engine on a forward-hinged hood.[citation needed]
Out of 61 companies that showed interest in the contract, five companies submitted proposals before the deadline in April 1981. In July 1981, the Army awarded contracts to three companies—AM General, Chrysler Corporation, and Teledyne Continental—to build eleven HMMWV prototypes each. The vehicles (six weapon carriers and five utility vehicles) were delivered by May 1982.
The Teledyne HMMWV was based on the rear-engined XR311 Cheetah. Chrysler's HMMWV was based on the Expanded Mobility Truck. Chrysler Defense was sold mid-competition to General Dynamics Land Systems. The AM General HMMWV was developed as a private venture to meet the HMMWV requirement. The first prototype (a weapons carrier variant) was completed in August 1980 and sent to the Nevada Automotive Test Center for testing. AM General nicknamed the prototypes it delivered for the Army competition "Hummer," which AM General had the foresight to trademark.
