URSA MAJOR IS ON A MISSION
TO SOLVE HYPERSONICS AT
SCALE
Ursa Major provides highly-capable and affordable hypersonic and long-range systems, with flight-proven performance across sustained Mach 5+ missions.
The Ursa Major HAVOC Missile System
Building the company’s work as an all-up-round provider and vehicle integrator on the on the Affordable Rapid Missile Demonstrator with the Air Force Research Laboratory, the company presents the Ursa Major HAVOC Missile System. This complete hypersonic missile system is powered by Ursa Major’s Draper liquid rocket engine and boosted by our in-house solid rocket motors. This introduces new class of affordable, maneuverable hypersonic munitions powered by our throttleable liquid rocket engine that eliminates the need for costly thermal protection and scramjet propulsion. This innovative capability enhances mission flexibility and unpredictability, establishing U.S. hypersonic arsenals across domains while complicating adversary missile defense strategies.

Affordable Rapid Missile Demonstrator
In 2026, Ursa Major flight tested its Draper-powered Affordable Rapid Missile Demonstrator as the lead vehicle integrator under a $28.6 million AFRL contract.
This mission validated Draper’s role as a storable, throttleable, and flight-ready solution for responsive space, on-orbit maneuver, and hypersonic strike. Learn more about our program with AFRL in the news.
Draper: Tactical, Storable, and the Future of Defense Propulsion
Developed in partnership with AFRL based on the flight-proven Hadley architecture, Draper is Ursa Major’s flexible liquid rocket engine, engineered for tactical hypersonics, missile defense, in-space propulsion, and space-based interception. With the storability of a solid motor and the maneuverability of a liquid system, Draper is reusable, throttleable, and safe. It operates on non-toxic, storable propellants – hydrogen peroxide and kerosene – using a closed catalyst cycle. Designed from the ground up for additive manufacturing, Draper went from concept to TRL6 in just three years, accelerating mission timelines and reducing cost. Whether intercepting a threat, maneuvering in orbit, or powering hypersonic flight, Draper delivers rapid response and unmatched flexibility across domains.
Hadley: Flight proven hypersonic propulsion
Hadley is a liquid rocket engine powering hypersonic and small launch missions. Delivering 5,000 lbf of sea-level thrust, and up to 6,500 lbf in its vacuum variant, Hadley runs on liquid oxygen (LOX) and kerosene using an oxygen-rich staged combustion cycle for exceptional performance.
It’s the first American engine of its kind to reach sustained Mach 5+ speeds and return, flying successfully with Stratolaunch’s Talon-A vehicle.
Built with 80% additive manufacturing, Hadley enables rapid iteration, reduced part count, and accelerated production timelines—setting a new standard for agile, affordable propulsion in contested and commercial environments.
