The M142 High Mobility Artillery Rocket System (HIMARS) is a light multiple rocket launcher developed in the late 1990s for the United States Army and mounted on a standard U.S. Army M1140 truck frame.
The M142 carries one pod with either six GMLRS rockets, or two PrSM missiles, or one ATACMS missile on the U.S. Army's new Family of Medium Tactical Vehicles (FMTV) five-ton truck and can launch the entire Multiple Launch Rocket System Family of Munitions (MFOM). M142 ammunition pods are interchangeable with the M270 MLRS; however, it is able to carry only one pod rather than the standard two for the M270 and its variants.
