RTX and Anduril complete successful test of advanced solid rocket motor

Recent test demonstrates collaborative innovation in rocket motor development

ARLINGTON, Va., Oct. 7, 2025 /PRNewswire/ -- Raytheon, an RTX (NYSE: RTX) business, and Anduril have successfully conducted a static fire test of an advanced solid rocket motor under a contract with the Air Force Research Laboratory Munitions Directorate.

In response to the increasing global demand for munitions, Raytheon has been working with domestic and international partners to enhance U.S.-based rocket motor manufacturing capacity.

"This test demonstrates more than just a technical achievement," said Colin Whelan, president of Advanced Technology at Raytheon. "It's about building a more robust and adaptable supply base for solid rocket motors that can rapidly respond to emerging national security needs."

By partnering with Anduril, Raytheon is expanding the defense technology ecosystem and addressing critical limitations in the rocket motor supply base. This collaboration exemplifies the company's composable weapons strategy, which aims to create more flexible and adaptable missile systems through strategic partnerships.

"Designing and firing a Highly Loaded Grain rocket motor is one of the most technically demanding tasks in the solid rocket motor industry," said LTG (ret.) Neil Thurgood, Senior Vice President, Anduril Industries. "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."
