US Defense Department cultivates new solid rocket motor suppliers

In an era defined by rapid technological advancements and escalating global tensions, the U.S. Department of Defense is strategically diversifying its solid rocket motor suppliers to mitigate risks associated with a concentrated supply chain. This move aims to revitalize domestic production capabilities for solid rocket motors, essential components in the arsenal of hypersonic weapons, conventional weapons, and nuclear missiles.

Historically, the production of solid rocket motors in the U.S. has been dominated by Northrop Grumman and L3Harris, following the latter’s acquisition of Aerojet Rocketdyne. These motors, which utilize a pre-mixed solid propellant, are pivotal in powering a broad spectrum of military applications, from tactical missiles to the country’s formidable nuclear-armed intercontinental ballistic missiles. 

However, the ongoing conflicts in Eastern Europe and the Middle East have underscored the existing production capacity’s limitations for tactical solid rocket motors, prompting the Defense Department to seek alternatives. 

New entrants emerge on the horizon 

One such newcomer making significant strides is Albuquerque-based X-Bow Systems. 

In the past year, X-Bow Systems has clinched nearly $100 million in contracts, a testament to the burgeoning demand for solid rocket motors. Notably, the company has entered into agreements exceeding $35 million with the Air Force Research Laboratory and secured a separate $64 million contract to furnish large solid rocket motors to the Navy and Army. 

Lockheed Martin Ventures’ investment in X-Bow underscores the importance and confidence in the company’s potential to contribute to national defense capabilities. 

X-Bow CEO Jason Hundley said the industrial base’s expansion for solid rocket motors is the first since the Cold War. He envisions the company spearheading the production of multiple solid rocket motor programs by year’s end, signifying a pivotal shift in the sector’s dynamics. 

Colorado’s Ursa Major is another emerging entity poised to disrupt the industry with innovative solutions. The company recently announced a collaboration with the Naval Energetics Systems and Technologies program, NEST, to develop and test a prototype solid rocket motor. 

Although the contract’s value remains undisclosed, Ursa Major’s endeavor reflects a broader ambition to rejuvenate the solid rocket motor industry with additive manufacturing techniques and a deep expertise spanning both solid and liquid rocket engines.

Anduril Industries steps into the arena 

Anduril Industries’ acquisition of Adranos, a niche solid rocket motor manufacturer, marks another critical development in this strategic diversification. 

Founded in 2015, Adranos’s integration into Anduril’s portfolio and the planned investments in its Mississippi manufacturing facility underscore the defense sector’s momentum toward enhancing solid rocket motor production capabilities. 

A new chapter for US defense 

The Defense Department’s investment in new entrants like X-Bow Systems, Ursa Major, and Anduril Industries reflects a concerted effort to address the dual challenges of supply chain concentration and surging demand for solid rocket motors. 

As these companies chart a new trajectory for the solid rocket motor industry, their innovative approaches and strategic partnerships herald a new chapter in U.S. defense, ensuring readiness and resilience in the face of evolving global threats.
