The Army selected five companies on September 29 to develop prototype extended-range missiles for PrSM Increment 4, targeting ranges exceeding 1,000 kilometers. The awards use Other Transaction Authority agreements to accelerate next-generation precision strike capability.
What's happening
- Anduril, Castelion, Lockheed Martin, Mach Industries and RTX received OTA agreements for PrSM Increment 4 prototype development on September 29, 2026.
- Each company will develop prototype missiles capable of launching from the M142 High Mobility Artillery Rocket system with ranges exceeding 1,000 kilometers.
- Lockheed Martin completed a key ground test demonstrating booster-to-ramjet handoff for its PrSM Increment 4 offering.
Why it matters
- PrSM Increment 4 extends U.S. ground-based precision strike range to 1,000 kilometers, significantly increasing Army artillery reach against near-peer threats.
- Competitive prototype phase with five contractors reduces technical risk and accelerates fielding of extended-range capability from mobile platforms.
- OTA agreements bypass traditional acquisition processes, enabling faster development and prototype evaluation cycles.
Going deeper
- The M142 HIMARS launcher will remain the baseline platform, constraining motor size and airframe dimensions for extended-range designs.
- Ramjet propulsion technology, demonstrated in Lockheed Martin's ground test, offers sustained thrust advantage over conventional solid-rocket boosters for extended range.
The intrigue
- Five concurrent prototype contracts suggest the Army views extended-range missile architecture as unsolved; competing booster versus ramjet approaches may emerge.
The fine print
- Contract ceiling value and obligated funds are undisclosed.
- Specific performance period and prototype maturity milestones not disclosed.
- Down-select to production program not confirmed.
