M142 HIMARS
WesternHigh Mobility Artillery Rocket System
The M142 HIMARS is a self-propelled rocket artillery system mounted on a wheeled 5-ton truck chassis. It fires the same rockets as the M270 MLRS but with a single six-round pod. Its long range, high precision, and rapid shoot-and-scoot capability made it a gamechanger when supplied to Ukraine from June 2022.
Primary Role
Long-range precision fires against HVTs — ammunition depots, command posts, bridges, artillery positions
First documented use in Ukraine: 2022-06-25

✓ Strengths
- •Extreme precision with GPS/INS-guided GMLRS rockets
- •Very long range — can strike well behind enemy lines
- •Rapidly relocates after firing (shoot-and-scoot)
- •Wheeled chassis — faster road movement than tracked MLRS
- •Can fire ATACMS ballistic missiles if permitted
⚠ Limitations
- •Only one pod (6 rockets) vs M270's two pods (12 rockets)
- •Dependent on US munitions supply chain
- •GPS jamming can reduce accuracy (mitigated by alternative guidance)
Notable Use
Ukraine used HIMARS to destroy over 400 Russian ammunition depots, command posts, and bridges in summer 2022 — fundamentally degrading Russia's logistics east of the Dnipro river and enabling the Kherson liberation.
Ukraine War Context
Ukraine received its first HIMARS systems from the US in June 2022. As of 2024, Ukraine had received 39+ HIMARS launchers. They were used to target high-value Russian logistics nodes, including railway junctions at Berdyansk, Melitopol, and Novoazovsk.
