Solid Rocket Motors Highlight Additive Manufacturing's Role in US Defense
Written with artificial intelligence.

The additive manufacturing (AM) sector is focusing on solid rocket motors (SRMs) as a key area for defense advancements. Companies like Ursa Major and Northrop Grumman are investing significantly in SRM production, emphasizing the need for a robust domestic manufacturing capability.
Focus on Solid Rocket Motors
While the additive manufacturing (AM) industry has turned its attention to drones, solid rocket motors (SRMs) remain a vital area for defense applications. The US defense sector is prioritizing SRMs, which have seen substantial investments and development efforts over the past few years.
Industry Investments
Companies such as Northrop Grumman have invested over $2 billion in SRM capacity, largely through AM technologies. Recently, Ursa Major secured $137 million in contracts from the US Navy for SRM development, which includes projects for the Compact Air-to-Air Missile and the Naval Modular Missile programs. These contracts follow Ursa Major's successful completion of earlier projects funded by a joint investment involving the Navy and the Office of Strategic Capital.
Importance of Propellant Production
The production of SRMs, particularly the propellant grain geometry, is critical for optimizing performance. Additive manufacturing not only allows for improved efficiency in burn rates and thrust but also enhances safety in the manufacturing process. The interest in AM from companies like Hanwha Defense highlights the growing recognition of these advantages.
Conclusion
The current emphasis on SRMs in the US military’s procurement strategy signals a pivotal moment for the AM industry. With significant investments and a focus on domestic production capabilities, the future of SRMs could reshape defense manufacturing priorities and practices.
