The test was conducted at the Naval Industrial Reserve Ordnance Plant at the Allegany Ballistics Laboratory and validated the reliability and consistency of the propulsion system powering the Army’s newest tactical strike missile. According to the company, the event marked another milestone in the PrSM program’s progression toward full operational capability.
“This test is our 16th consecutive, successful, PrSM production acceptance test,” said Erik Buice. “This string of successes reinforces the strength of our tactical propulsion portfolio and the teams who make it possible.”
Buice added: “We’re building rocket motors that don’t just meet performance targets — they redefine what’s possible for range, responsiveness and reliability when needed most.” Northrop Grumman stated that the PrSM Increment 1 motor was designed, cast and tested by the company using modernized facilities, advanced materials, new hardware designs and a robust supplier network.
The company noted that PrSM is one element of a broader tactical propulsion portfolio that includes rocket motors and boosters supporting air defense interceptors, guided munitions and missile defense systems across land, air and sea domains. Teams at Allegany Ballistics Laboratory also support programs such as the Guided Multiple Launch Rocket System and the Integrated Air and Missile Defense portfolio.
With rising demand across the defense industrial base, Northrop Grumman said it has invested heavily in manufacturing and test infrastructure to scale production while maintaining performance. “Our teams are proving that readiness isn’t a future goal; it’s a standard we meet every day,” Buice said, adding that “every successful test, like this one for PrSM, demonstrates that our propulsion is ready when the mission calls.”
