M142 HIMARS

Also known as
  • M142
  • High Mobility Artillery Rocket System

The M142 HIMARS is a U.S.-built wheeled rocket and tactical missile launcher produced by Lockheed Martin for mobile precision fires. It carries one six-rocket pod, two PrSM missiles, or one ATACMS missile, uses a five-ton truck chassis with an armored cab, and can deploy by C-130-class airlift. Lockheed Martin reported the 750th launcher delivery in November 2025, while its combat record spans U.S. operations and Ukrainian long-range fires against Russian forces.
