Northrop Grumman has conducted another successful precision strike missile (PrSM) rocket motor static test at its facility.

The test was performed to prove and confirm the design of the rocket motor before it is moved into production.

During the test, the motor fulfilled performance requirements for ‘extremely cold temperatures’.

Northrop Grumman missile products vice-president Rebecca Torzone said: “With another successful rocket motor test complete, we are one step closer to providing the US Army with next-generation, long range fires capability.

“Our new motor delivers enhanced performance that translates to increased weapon load out and standoff for our warfighter.”

The rocket motor will be put through more qualification tests prior to its initial fielding in 2023.

The PrSM is a next-generation precision-strike, surface-to-surface weapon system, developed by Lockheed Martin, to replace the US Army’s army tactical missile system (ATACMS).

The missile is designed to enhance the army’s ability to neutralise a range of enemy threats on the battlefield.

When compared to ATACMS, PrSM, upgraded with the new Northrop Grumman rocket motor, provides extended range and load out with two missiles per launch pod.

Work on the PrSM propulsion system is carried out at Northrop Grumman’s manufacturing facility at the Allegany Ballistics Laboratory in Rocket Centre.

The tactical solid rocket motor production facility is equipped with several digital technologies to increase affordability.

In October last year, Lockheed Martin completed the fifth test-firing of the long-range PrSM.
