A hybrid 3D-printed rocket system from Firehawk Aerospace has soared past the speed of sound in a live test, marking a step toward potential US Army use in the future.
Dubbed Firehawk Analog, the 3D-printed engine was integrated into a test rocket that climbed to 18,000 feet (5,486 meters) after launching from a mobile platform.
The motor is built to match the Guided Multiple Launch Rocket System (GMLRS) class, meaning it could eventually be tested and swapped into existing army missile bodies.
“This milestone proves that hybrid propulsion systems, when paired with advanced additive manufacturing, have a real place in the future of tactical systems,” said Firehawk Chief Executive Officer Will Edwards.
He added that the test “underscores the strength and innovation” of the company’s engineering team, constructing a system with directional stability and thrust performance.
‘Faster Builds, Lower Costs’
The demo is part of Firehawk’s ongoing Small Business Innovation Research (SBIR) Phase 3 contract with the US Army, aimed at eliminating supply chain risks in rocket motor production.
The effort began two years ago to streamline how the service develops solid rocket propulsions for tactical use.
As part of the agreement, the company will also test its 3D-printed Javelin-class and Stinger-class analogs, which could serve as potential substitutes for current in-service motors.
By using hybrid propellants and 3D-printed components, Firehawk said it can cut production timelines from years to weeks and enable easier testing with reduced costs.
“The Phase III funding reflects our team’s ability to push aerospace technology boundaries, positioning Firehawk at the forefront of innovation in tactical weapon systems,” Edwards stated.
