HIMARS is a transformational 24 hour, ground-based, responsive General Support / General Support-Reinforcing (GS/GSR) precision indirect fire support system which accurately engage targets at long ranges (60+ Km) with high volumes of lethal fire under all weather conditions throughout all phases of combat operations ashore. HIMARS is C-130 and amphibious transportable and with precision fires, supports both irregular and traditional warfare. One HIMARS system is defined as one launcher, two resupply vehicles / trailers and munitions.
The High Mobility Artillery Rocket System (HIMARS) TD will provide a lightweight, C–130 transportable version of the M–270 multiple launch rocket system (MLRS) launcher. Mounted on a 5–ton family of medium tactical vehicles (FMTV) truck chassis, it will fire any rocket or missile in the MLRS family of munitions [MFOM]. The HIMARS launchers will some commonality with its older and heavier tracked cousins, the M270 and M270A1 launcher systems. The HIMARS design concept will include the familiar launcher module, fire control, and digital command and control systems, and a self-reload capability. The HIMARS uses the same command, control, and communications, as well as the same crew, as the MLRS launcher but carries only one rocket or missile pod. It will roll on and off a C–130 transport aircraft and, when carried with a combat load, will be ready to operate within 15 minutes of landing. The HIMARS will fire either six MLRS rockets or one Army Tactical Missile. Because of the lighter weight of using one pod rather than two, it will have a faster time, compared to the current M270, from the point the fire mission is received to the actual munition firing.
