Ursa Major has introduced the HAVOC Missile System, a medium-range hypersonic weapon designed to deliver high-speed, maneuverable strike capability at scale while sharply reducing unit costs. Centered on the company’s Draper liquid rocket engine, HAVOC is built for rapid production using advanced additive manufacturing and streamlined design, positioning Ursa Major as a key supplier for U.S. hypersonic inventories.
The system’s throttleable, restartable propulsion enables precise control across all flight phases, reducing reliance on expensive thermal protection and differentiating it from traditional boost-glide and cruise concepts. HAVOC’s modular architecture supports integration with multiple solid rocket boosters and launch from fighters, bombers, vertical launch systems, or ground platforms, giving defense customers multi-domain flexibility for both endo- and exo-atmospheric missions.
Ursa Major’s CEO Chris Spagnoletti emphasized that the system was conceived for speed to delivery, affordability, and volume production, aligning with U.S. defense priorities to lower hypersonic costs and expand industrial capacity. The company leverages more than a decade of hypersonic development and flight experience, including its Hadley engines, which have already flown in hypersonic regimes and validated liquid propulsion performance in operationally relevant conditions.
In parallel, Ursa Major has demonstrated full vehicle design and build capabilities through the Affordable Rapid Missile Demonstrator program with the Air Force Research Laboratory, which is nearing flight and reinforces the firm’s credibility as more than a component supplier. Collectively, HAVOC and these programs position Ursa Major to benefit from rising demand for survivable, maneuverable hypersonic systems and to play a central role in revitalizing the U.S. defense industrial base for next-generation strike and target capabilities.
