Anduril Rocket Motor Systems (RMS) has officially opened its full-rate solid rocket motor (SRM) facility in McHenry, Mississippi, the company announced on 5 August. The milestone comes 18 months after ground was broken in January 2024, according to an Anduril blog post, which noted that the Mississippi Solid Rocket Motor Complex has grown from 40 to 100 employees and test-fired more than 700 motors in that timeframe.

The new site is expected to reach annual production of around 6,000 tactical SRMs by the end of 2026, the blog post said. Anduril's original facility at McHenry will continue to focus on low-rate production and advanced research and development (R&D), prototyping new designs, testing novel materials, and refining manufacturing processes, the blog post added.

The company highlighted two successful Standard Missile live-fire tests for the US Navy in April 2025 following a “rapid and iterative design phase … [that] positions Anduril to quickly transition to full-scale production”.

“Anduril [RMS] is working [on] rocket motor programmes directly with the military services and the Department of Defense [DoD]… The preponderance of what we're doing is supporting other teammates across the industrial base with the design, development, and now the capacity for full-scale production of solid rocket motors of various different classes,” Chris Brose, president and chief strategy officer for Anduril, told journalists during a briefing on 1 August.
