US' interceptor with solid motor can perform better against threats

The U.S. Army’s Next-Generation Short-Range Interceptor (NGSRI), developed by Raytheon and Northrop Grumman, has successfully undergone multiple tests of its solid rocket motor technology, known as Highly Loaded Grain (HLG). This advanced solid propellant offers longer burn times and greater energy output than conventional motors, enabling the missile to fly faster, extend its range, and perform more effectively against advanced aerial threats. The program has completed three static firings in varied environments and a successful ballistic flight demonstration, with further tests planned soon. The missile’s design allows it to be launched from various platforms, including tripods, vehicles, and shoulder launchers. Raytheon and Northrop Grumman’s collaboration has rapidly transitioned the HLG motor from concept to flight-ready status in under six months, leveraging modular design and automated manufacturing techniques. This propulsion innovation enhances speed, range, and mission flexibility in a compact form factor, marking a significant advancement over legacy air defense systems. The NGSRI builds on over 60 years of air defense expertise to deliver a highly capable shoulder-launched missile for the U.S. Army and Marine Corps, aiming to protect warfighters against evolving airborne threats with cutting-edge technology.
