Northrop Grumman has announced the acquisition of a substantial contract exceeding $200 million to manufacture the XM1211 High Explosive Proximity rounds for the United States Army. This medium-caliber munition will play a crucial role in the Army’s efforts to enhance its short-range capabilities against small unmanned aerial systems (UAS).
The XM1211 shell, designed to be fired from the XM914 and M230LF Bushmaster 30-millimeter chain guns, features an advanced proximity sensor. This sensor triggers detonation to maximize fragmentation effects when the shell is near its intended target, providing a tactical advantage on the battlefield.
The development of the XM1211 involved collaboration with multiple Army entities, including the Joint Program Executive Office for Armaments and Ammunition, PM Maneuver Ammunition Systems, and the Combat Capabilities Development Command. The shell was expedited for production in 2021 to address an urgent operational requirement, showcasing Northrop Grumman’s ability to respond rapidly to military needs.
To meet increased demand from both the US military and allied forces, Northrop Grumman is ramping up production across its facilities in Minnesota, West Virginia, and Virginia. “As the only qualified producer of the XM1211 proximity round, Northrop Grumman is uniquely positioned to deliver this urgent need for advanced munitions with speed,” stated the vice president of armament systems at Northrop Grumman. He emphasized the company’s commitment to innovation in partnership with the US Army, underlining the importance of supporting soldiers engaged in active operations.
In addition to the ammunition project, Northrop Grumman is also making strides in rocket technology. The company recently completed a static test of a new solid rocket motor as part of its Solid Motor Annual Rocket Technology Demonstrator (SMART Demo) program, which promotes innovation in military solutions through collaboration with industry partners.
The test involved the 22-inch diameter Solid Motor Adaptable, Scalable, Half Time/Cos, or “SMASH!22.” Focused on evaluating manufacturing processes and materials, the test aims to enhance production speed, effectiveness, and cost-efficiency. The data collected will inform the subsequent development of a second rocket motor, the 29-inch Bombardment Attack Missile Motor 2.0, or “BAMM!29 2.0,” expected to undergo testing in early 2026.
Both rocket motors leverage insights gained from prior Northrop projects and include 3D-printed components alongside updated tooling aimed at streamlining manufacturing timelines. This comprehensive approach underscores Northrop Grumman’s dedication to delivering advanced defense capabilities while maintaining agility in production processes.
