M142 HIMARS

The United States' wheeled, C-130-transportable precision rocket artillery system — battlefield-proven in Ukraine and known as the "sniper of artillery," firing GMLRS, ATACMS, and the future PrSM.

Overview

The M142 High Mobility Artillery Rocket System is a wheeled, shoot-and-scoot multiple-launch rocket system (MLRS) that fires the same Family of Medium-calibre Ordnance (MFOM) as the tracked M270 but on a lighter, more mobile 6×6 truck chassis. Designed to provide brigade-and-above commanders with rapid, long-range precision fires, a single launcher swaps between pods holding six 227 mm guided rockets, one ATACMS ballistic missile, or two next-generation Precision Strike Missiles (PrSM). Because it fits inside a C-130, HIMARS can deploy to austere strips that the heavier M270 cannot reach, a feature proven decisive in the system’s extensive combat career.

Development

Lockheed Martin began developing HIMARS in the late 1990s as a lighter, more deployable complement to the tracked M270 MLRS. The first prototype appeared in 1999, and Army Technology notes that the U.S. Army took delivery of its first operational launchers in 2005, with the U.S. Marine Corps following in 2007. Early production focused on replacing towed howitzers in rapid-deployment units, and a series of incremental upgrades—most notably the integration of the Universal Fire Control System—allowed the launcher to fire the full MFOM suite, including the longer-range ATACMS. The U.S. Army continues to fund multi-year procurement contracts, with production sustained by both domestic and foreign orders.
