Over the past five months, Northrop Grumman has demonstrated its engineering excellence by executing three company-funded static tests, proving that high-performance, affordable motors can be conceived, built, and validated in under one year.
Driving Innovation at the Edge of Physics
Solid rocket propulsion operates at the edge of physics, transforming extreme technical complexity into dependable performance for missions ranging from deep-space exploration to national defense. The motors used in all three static tests — completed in less than one year — demonstrate the company’s ability to push the boundaries of power, affordability, and innovation.
The most recent static test utilized a Northrop Grumman large solid rocket motor as a test bed to demonstrate design improvements, analytical models, and a new propellant that will enhance current and future solid rocket motors across the company’s portfolio. Northrop Grumman’s propulsion teams employ advanced manufacturing, new materials, and analytics to build rockets that power both defense missions and deep-space projects.
Jim Kalberer, Vice President of Propulsion Systems at Northrop Grumman, stated:
“We see solid-rocket propulsion as a driver of the future — using disciplined testing and rapid manufacturing cycles for both defense and deep-space missions. These critical tests set a new industry standard, giving our customers confidence in every mission.”
Driving Cost-Effective, High-Performance Solid Rocket Motors
A new propellant used in recent demonstration solid-rocket tests delivers the same or more energy than current fuels in a lower-cost formulation and can power new space-launch or hypersonic rockets. This propellant can be manufactured across multiple sites, providing consistent performance and meeting increased demand across various applications. When rocket performance is more consistent, it expands the range of missions the motor can handle, boosts reliability, and allows the company to produce larger numbers of solid-rocket motors for launch vehicles.
Alongside material advancements, the company is advancing large solid-rocket motors through updated designs, new material-making processes, and advanced computer models. These models accurately predict how hot gases, heat, material behavior, and surface wear will perform, enabling engineers to fine-tune performance and durability. The team rigorously tests these models to ensure they consistently forecast ballistic, mechanical, and structural results — demonstrating the company’s dedication to engineering excellence, cost-effective reliability, and high-performance propulsion.
Jim Kalberer added:
“Our latest breakthroughs are not just about making solid rocket motors better — they are about redefining what is possible. Faster production, smarter design, and cost-saving innovations mean we are delivering cost-effective, unstoppable propulsion power for today’s toughest missions.”
Category Leadership and Future Commitment
As the propulsion foundation of critical space and defense programs, Northrop Grumman embraces its responsibility to engineer with precision and test with discipline. The company’s SMART Demo program — now in its third year — has driven advances in solid rocket motor technology, delivering new capabilities that reduce development time and cost without sacrificing performance. Over the past seven years, the company has invested more than $1 billion to expand and modernize its Utah facilities — a strategic effort to meet growing customer demand and achieve the goal of doubling production capacity before 2030.
