Northrop Grumman nabs US Navy SSRM contract

The US Navy has awarded Northrop Grumman with a USD 94.3 million contract to develop and qualify a new 21-inch diameter second-stage solid rocket motor (SSRM) for the Navy’s extended-range missile programs to deter and defeat fast-moving air, surface and hypersonic threats.

The SSRM is a low-risk, rapidly developed design that enables the Navy to quickly and cost-effectively field an extended-range hypersonic defense capability.

The high-performance 21” diameter rocket motor is engineered to significantly extend range and speed across various missions, including air warfare, surface warfare, land strike, and ballistic missile defense.

The Navy has expressed interest for potential deployment of Northrop Grumman’s extended range propulsion technology across various platforms.

Continued design and low-rate initial production of 60 units for testing and delivery will take place at Northrop Grumman’s Propulsion Innovation Center in Elkton, Md.

Gordon LoPresti, senior director, propulsion systems and control, Northrop Grumman, said: ”Being chosen by the U.S. Navy is an honor and a testament to our rapid development capabilities, production capacity and leadership in advanced propulsion solutions. The successful development and demonstration of our SSRM in just 10 months showcases our unique, affordable, and versatile extended-range capabilities that will equip the U.S. Navy to excel in its defense and deterrence missions. We are eager and prepared to rapidly qualify and produce these motors in quantities to meet the needs of the US.”

To meet the growing customer demand, Northrop Grumman has invested nearly $1 billion since 2018 to enhance capacity and capabilities for weapons and missile components, including solid rocket motors.

Propulsion work takes place across six strategic sites in West Virginia, Utah and Maryland, totaling 10 million square feet of manufacturing space. The company said it is tripling capacity for small tactical SRMs at its West Virginia production facility, doubling production capacity for large SRMs in Utah, and increasing by 25% manufacturing capacity in Maryland to accommodate future high-demand programs, including air-breathing hypersonic propulsion solutions.
