Anduril secures $43 million in US funding for solid rocket motor production

The US has awarded Anduril an additional $43.7 million in DPA funding to scale up domestic production of solid rocket motors. The announcement comes as the US is taking some big steps to increase its missile production.

Anduril has been awarded $43.7 million in additional funding under the Defence Production Act to increase its production of solid rocket motors. The funding, awarded on 2 October 2025, but announced February 19 this year, is intended to expand production capacity at Anduril’s factory in Mississippi. 

It follows an initial investment of $14.3 million (£11 million/€13.24 million) provided by the government in December 2024. Combined with Anduril’s own $75 million (£57.8 million/€69.43 million) investment, the capital will be used to increase the efficiency of the facility through:

• Expanded test fire infrastructure for complex motors.
• Increased storage capacity for finished units.
• Acquisition of production tooling required for manufacturing-level quantities.

The investment aims to address critical supply chain constraints in the American munitions base. Before Anduril set up its own production line, through the 2023 acquisition of company Adranos, there were only two rocket motor manufacturers in the US, the Anduril press release states. When full-rate production started at the Mississippi facility in August 2025, Anduril became the third. 

Solid rocket motors are essential components for both legacy weapon systems and future modernization programmes. By funding Anduril, the US government and Congress seek to diversify the industrial base to meet the demands of conventional deterrence and potential large-scale conflicts.

Calibre comment: Increasing America’s missile output

Since receiving its initial government funding, Anduril has secured several key contracts, including:

• A full-rate production contract with a European ally for a tactical air defence system.
• A partnership with Saab to supply the rocket motor for the Ground Launched Small Diameter Bomb
• Cooperated with Raytheon to test a new extended range rocket motor for air-to-air missiles. 
• And won a US Army contract to produce new rocket motors for the HIMARS. 

However, the company’s products are part of a much larger ecosystem. The US defence industrial base has signed a raft of announcements and frameworks designed to dramatically increase missile production. That demand, which includes quadrupled production of some missiles, will be a significant driver for solid rocket motor production.

• Anduril selected to develop new rocket motor for US Army 

Production of rocket motors is a known bottleneck in missile output. It is an intensive and time-consuming process. The current output reflects demand over the past 30 years, and reshaping that for future scenarios is going to take time and money.
