🇺🇸— According to TWZ, the United States’ hypersonic weapons programs are increasingly adopting 3D-printed air-breathing engines, and companies including Aerojet Rocketdyne, Ursa Major, and Lockheed Martin/Velo3D are using additive manufacturing to produce complex parts for scramjet and ramjet engines whose production is difficult and costly by conventional methods. Ursa Major says that AI-enabled metal 3D printing has made it possible to develop the hypersonic missile Havoc and the liquid rocket engine Draper, while also accelerating production of solid rocket engines. The company says its modular manufacturing approach enables rapid changes in design and scalable production, placing it in a position to help address the United States’ critical ammunition shortages and expand affordable hypersonic missile production. 🔴
