The Polish Minister Mariusz B?aszczak published that Poland signed a Letter of Request (LOR) to the US government regarding the purchase of more M142 High Mobility Artillery Rocket System (HIMARS) mobile rocket launchers. In November 2018, Poland has requested to buy twenty (20) High Mobility Artillery Rocket System (HIMARS) M142 Launchers, thirty-six (36) Guided Multiple Launch Rocket System (GMLRS) M31 Unitary, nine (9) Guided Multiple Launch Rocket System (GMLRS) M30A1 Alternative Warheads, thirty (30) Army Tactical Missile System (ATACMS) M57 Unitary, twenty-four (24) Advanced Field Artillery Tactical Data Systems (AFATDS), twenty (20) Multiple Launcher Pod Assembly M68A2 Trainers, twenty-four (24) M1151A1 High Mobility Multi-purpose Wheeled Vehicles (HMMWVs), and nine (9) M1151A1 High Mobility Multi-purpose Wheel Vehicles (HMMWVs).
The M142 HIMARS is a wheeled Multiple Launch Rocket System that can fire up to six rockets at a time. The rockets depending on the model can carry submunitions for area suppression or a single unitary blast warhead. It also uses the Army Tactical Missile System, a long-range battlefield missile with a range of over 190 miles. Previous versions were capable of carrying submunitions, but current models use a single blast-fragmentation warhead due to international concern over the effects of unexploded cluster munitions on civilian populations. The HIMARS is a light multiple rocket launcher developed jointly in the late 1990s by the Companies BAE Systems and Lockheed Martin for the United States Army. The truck chassis is produced by BAE Systems Mobility & Protection Systems while the he rocket launching system is produced by Lockheed Martin Missiles & Fire Control.
