The MJ-1 is a standard lift truck used to transport, load and unload a wide variety of munitions and other stores. A 25-hp engine powers the drive wheels and cantilever lift arm, which has a capacity of 3,000 pounds.
The MJ-1 (also called a "jammer") has served as the standard USAF bomb load vehicle since the 1950s. It was used extensively during both the Vietnam War and the Persian Gulf War. The MJ-1 can lift stores to a maximum height of 78 inches and uses side fork adapters and extension lift arms for increased flexibility. Controls at the rear of the lift table allow the load crew to make small adjustments for precise positioning of stores during loading. The MJ-1 was received from the Flightline Support Equipment Branch at Kelly Air Force Base, Texas, in 1991.
