Raytheon, an RTX business, and Northrop Grumman have successfully conducted four tests of Highly Loaded Grain (HLG) solid rocket motors for the U.S. Army’s Next-Generation Short-Range Interceptor (NGSRI). This solid propellant technology enables longer burn time and increased energy output, extending the range of the interceptor compared to existing systems.

Raytheon, an RTX business, and Northrop Grumman have successfully conducted four tests of Highly Loaded Grain (HLG) solid rocket motors for the U.S. Army’s Next-Generation Short-Range Interceptor (NGSRI). This solid propellant technology enables longer burn time and increased energy output, extending the range of the interceptor compared to existing systems.

 

The NGSRI is a new short-range missile designed to outperform current interceptors in speed and effectiveness against aerial threats. It is versatile in deployment, capable of being launched from a tripod, vehicle, or shoulder.

In recent testing, the teams completed three static firings in varied environments, followed by a successful ballistic flight demonstration. More flight tests are planned in the coming months to further validate the system.

 

 

“These tests demonstrate our ability to rapidly develop this transformational air defense capability, which can defeat a variety of airborne threats at far greater ranges than legacy systems,” said Tom Laliberty, president of Land and Air Defense Systems at Raytheon. “Alongside Northrop Grumman, Raytheon is delivering cutting-edge technology to protect our warfighters.”

Development of the extended-range motor has been supported by collaborative research at Northrop Grumman’s Allegany Ballistics Laboratory in West Virginia. The project transitioned from concept to first flight in under six months.

“Northrop Grumman continues to push the boundaries on next-generation propulsion technology, and we’re excited to work with Raytheon to bring this advanced solution for warfighters at record pace,” said Frank DeMauro, vice president and general manager, Weapon Systems, Northrop Grumman. “Developed and demonstrated in five months, this innovative HLG motor provides increased speed, range, effectiveness and mission flexibility in a very small package.”

 

 

Raytheon’s NGSRI design benefits from more than 60 years of air defence expertise, offering what the company describes as the world’s most advanced shoulder-launched air defence missile for the U.S. Army and Marine Corps. A modular system design and automated manufacturing approach have helped accelerate both development and production.
