Northrop Grumman has achieved a significant milestone in two new solid rocket motor technologies developed under the SMART Demo program. The company successfully conducted a static fire test for the first of the SMASH!22 and BAMM!29 2.0 motors, designed and manufactured in 2025.
SMASH!22 Rocket Motor: Advanced Manufacturing and Cost Optimization
The SMASH!22 is a 22-inch diameter motor with a “Solid Motor Adaptable, Scalable, Half Time/Cost” configuration. This test was conducted to analyze the effects of advanced manufacturing methods, new materials, and innovations in production processes on the motor’s performance, cost, and timeline. With the comprehensive data package obtained from this test, Northrop Grumman has deepened its expertise in solid rocket motor technologies.
BAMM!29 2.0: Next Static Test Planned for Early 2026
The BAMM!29 2.0 is a 29-inch diameter motor referred to as the “Bombardment Attack Missile Motor.” The static test for this critical motor is planned for early 2026.
The core objective of the SMART Demo program is to rapidly adapt and tailor solid rocket motors to the evolving requirements of the defense and space sectors. Northrop Grumman developed the SMASH and BAMM motors using data from previous projects, significantly accelerating production processes through the use of advanced machine tools, additive manufacturing components, and a diversified supplier network.
This recent achievement stands as strong evidence that Northrop Grumman can meet its ambitious goals in both development time and cost.
