# Army Awards PrSM Prototype Agreements

On September 29, 2026, the U.S. Army awarded separate Other Transaction Authority (OTA) agreements to Mach Industries, Anduril, Castelion, Lockheed Martin Missiles and Fire Control, and RTX to prototype missiles for the Precision Strike Missile (PrSM) Increment 4 competition. The Army is seeking HIMARS-compatible weapons able to engage moving maritime and relocatable land targets at ranges of 1,000 kilometers or more; Mach says its offering is based on its Pike long-range strike platform. Competitive flight demonstrations and a down-select are planned for FY2027, followed by another demonstration and potential follow-on agreements in FY2028.

- The five prototype efforts create near-term opportunities for suppliers supporting missile development, testing, and HIMARS integration; no agreement values or solicitation numbers were reported.
- Companies considering participation should align potential contributions with the stated range, target-engagement, and HIMARS-compatibility objectives.
- FY2027 demonstrations and down-selection are the next identified competitive milestones, with potential follow-on agreements planned for FY2028.
