Saab Chooses Anduril Rocket Motor Systems to Design and Produce SRM for the GLSDB Weapon System

Saab, Inc. has selected Anduril Rocket Motor Systems as a supplier to design, develop, qualify, and eventually produce Solid Rocket Motors (SRM) in support of the Ground-Launched Small Diameter Bomb (GLSDB) system, delivered in partnership with Boeing. Anduril was selected for our ability deliver propulsion systems quickly, at scale, and more affordably than competitors.

Anduril is delivering a modern, high-performance replacement motor which will meet the existing performance and mass properties of the M26 MLRS solid rocket motor currently powering GLSDB. Leveraging an improved design optimized for safety and affordability, new sub-tier suppliers, and Anduril’s novel manufacturing technologies, Anduril brings significant capacity, enabling the delivery of GLSDB systems in larger quantities for customers. Anduril has already commenced work to develop and qualify the system with plans to transition it to full rate production in 2026.

Affordable long range precision fire weapons are fundamental to the United States and allied nations’ security interests. Challenged by an oversaturated supply base, the SRM industry has struggled to keep up with the increasing demand for motors. The GLSDB system is combat-proven and uniquely flexible—offering a more affordable alternative to legacy precision strike systems. Saab’s decision to partner with Anduril reflects confidence in our ability to meet this moment with speed, innovation, and reliability.

Anduril is investing $75 million of private capital for a facility expansion in McHenry, Mississippi to ultimately deliver critical technology to warfighters faster. Once the expansion is completed in July 2025, the facility will bring significant additional capacity to the U.S. and allied industrial base, helping to close a critical gap in the supply of affordable rocket motors for long range systems. Compounded with a recent $14.3M Defense Production Act award, we are applying single-piece-flow manufacturing, bladeless high-speed mixer, and automation new to the SRM industry to efficiently and affordably produce and qualify these propulsion systems. Most recently, Anduril Rocket Motors successfully completed a static test fire of its 21-inch hypersonic rocket motor for the U.S. Navy's STANDARD Missile Program.

In 2022, Anduril set out to become an independent, merchant supplier of SRMs; our support of the GLSDB weapon system is proof of progress. We are committed to delivering the speed, scale, and affordability required for credible deterrence.
