In response to rising global demand for munitions, Raytheon has been working with domestic and international partners to expand U.S.-based rocket motor manufacturing. The static-fire milestone is presented as more than a pure technical achievement. “It’s about building a more robust and adaptable supply base for solid rocket motors that can rapidly respond to emerging national security needs,” said Colin Whelan, president of Advanced Technology at Raytheon.

The partnership with Anduril broadens the defence-technology ecosystem and tackles critical limitations in the rocket-motor supply chain. The collaboration aligns with Raytheon’s composable weapons strategy, which seeks to create more flexible and adaptable missile systems through strategic alliances.

Highlighting the technical challenge of the work, LTG (ret.) Neil Thurgood, Senior Vice President at Anduril Industries, commented: “Designing and firing a Highly Loaded Grain rocket motor is one of the most technically demanding tasks in the solid rocket motor industry. Achieving this result highlights the strength of Anduril’s engineering team and demonstrates our ability to deliver high-performance propulsion solutions in a domain long defined by a small set of providers.”

The successful static fire underlines both companies’ roles in addressing supply-base resilience and advancing propulsion capabilities for defence applications.
