An industry analysis published by 3DPrint.com on October 10 points out that solid rocket motors (SRMs) are becoming the first real-world validation scenario for whether additive manufacturing can achieve true scale in the US defense sector: driven by both the need to replenish munition stockpiles and domestic supply shortages, the US missile and munitions procurement budget has grown from $9 billion in 2015 to $30.6 billion in 2024. Leading players are accelerating their positioning: Northrop Grumman has invested over $2 billion in SRM production capacity over the past few years, and its SMART validation program used Titomic's cold spray additive manufacturing (CSAM) technology to complete a hot-fire test of a 3D-printed thrust chamber; Ursa Major received two US Navy contracts totaling $137 million (CAAM program: $91 million + NMM program: $46 million), with its Lynx process capable of printing motors ranging from 2 to 22 inches in diameter; a long-range SRM developed by Raytheon (RTX) in partnership with Ursa Major completed US Army flight tests; Firehawk Aerospace achieved milestones in 3D-printed propellant motors at the Javelin and Stinger class, reducing the cast-cure cycle from 15–60 days to 3–6 hours. The ramping up of SRM production will drive demand for metal additive manufacturing and cold spray metal powders for nozzle throat inserts and casings, and superalloys, titanium alloys, and cold spray metal powders are expected to see sustained volume growth alongside the expansion of US arms production.
