Firehawk

Firehawk Aerospace develops solid and hybrid rocket motors using additive manufacturing, with a focus on tactical defense applications and small launch. Its 3D-Ultra propellant technology lets engineers print grain structures directly, which means thrust profiles can be tuned per mission and motors can move from design to test in weeks rather than years. The hybrid line uses a 3D-printed solid fuel grain paired with liquid nitrous oxide as the oxidiser, giving operators the ability to throttle a large engine down by roughly 5x in flight. The company has worked closely with the US Army Applications Laboratory under a Phase III SBIR contract and completed flight tests of additively manufactured Javelin-class and Stinger-class motors. A first flight test of a 3D-printed Guided Multiple Launch Rocket System analogue followed in 2025. Headquarters are in the Dallas area, with a propulsion test site in McGregor, Texas.
