Ursa Major

What Ursa Major does

Ursa Major Technologies, Inc. is a privately held, venture-backed aerospace and defense company founded in 2015 and headquartered in Berthoud, Colorado. The company designs, manufactures, and tests advanced propulsion systems for hypersonic missiles, solid rocket motors (SRMs), and in-space satellite applications, with more than 80% of engine and motor mass produced via additive manufacturing. Its product portfolio spans storable liquid rocket engines (Draper), oxygen-rich staged combustion engines (Hadley, Ripley), a methane full-flow staged combustion engine (Arroway), the Lynx mixed-model SRM manufacturing process capable of producing motors from 2 to 22 inches in diameter on a single line without retooling, the Highly Loaded Grain (HLG) propellant technology, hydrazine-based in-space propulsion systems, and the HAVOC all-up-round hypersonic missile system unveiled in February 2026.

The company's vertically integrated production footprint spans six U.S. locations including a headquarters with machining and integration capabilities in Berthoud, Colorado; a 400-acre SRM test and qualification site in Weld County, Colorado; SRM production in Galeton, Colorado; a $14.5 million additive manufacturing R&D facility in Youngstown/Boardman, Ohio (expanded 10x); programmatic operations in Huntsville, Alabama; and a government relations office in Washington, D.C. Revenue is generated through firm-fixed-price contracts, IDIQ awards, and joint investments from U.S. DoD customers (AFRL, U.S. Navy, U.S. Army, Missile Defense Agency, U.S. Army Space and Missile Defense Command), subcontracts with defense primes (RTX/Raytheon, BAE Systems), direct hardware sales of engines and SRMs (Stratolaunch, Sirius Technologies), and emerging prime-contractor sales of the HAVOC missile system with a target unit cost under $3 million. As of November 2025, Ursa Major had raised over $300 million in cumulative capital, including a $100 million Series E led by Eclipse Ventures at a $600 million post-money valuation with $50 million in additional debt commitments.

Direct peers

• Aerojet Rocketdyne (L3Harris): Aerojet Rocketdyne, now part of L3Harris, is the most direct competitor to Ursa Major in liquid and solid rocket propulsion for defense and space launch. Both companies supply SRMs and liquid engines to U.S. DoD primes and the government, and L3Harris is one of the two legacy SRM suppliers Ursa Major is positioning against.
• Northrop Grumman: Northrop Grumman (via the legacy Orbital ATK business) is one of the two remaining U.S. solid rocket motor suppliers and a major propulsion integrator. Ursa Major is explicitly positioning Lynx and its SRM portfolio as an alternative to Northrop Grumman's franchise, including on standard missile-class motors.
• RTX (Raytheon): Raytheon is both a Ursa Major customer (co-developing long-range 3D-printed SRMs for the U.S. Army) and a broader propulsion and missile systems competitor. Both companies field integrated solid rocket motors and hypersonic-class systems, with Raytheon acting as integrator on multiple Ursa Major-supported programs.
• Rocket Lab: Rocket Lab designs and manufactures its own liquid rocket engines (Rutherford, Archimedes, Neutron) and in-space propulsion systems. It competes with Ursa Major in the small-to-medium launch and satellite propulsion markets and shares a vertically integrated, privately held propulsion development model.
• Relativity Space: Relativity Space builds 3D-printed rockets (Terran 1, Terran R) using large-format additive manufacturing, making it one of the closest analogues to Ursa Major's AM-first propulsion approach. Both companies bet on additive as the path to faster, cheaper aerospace hardware.
• Firefly Aerospace: Firefly develops its own in-house liquid rocket engines (Reaver, Lightning) for small-to-medium launch and is also a participant in U.S. DoD space and defense work. It competes with Ursa Major in the small launch propulsion market and shares a similar customer mix across commercial and government launch.

Broad incumbents

• SpaceX: SpaceX develops reusable liquid rocket engines (Merlin, Raptor) and is one of only two other U.S. companies to have proven and reflown a hypersonic-class liquid engine. While SpaceX focuses on commercial launch, the underlying propulsion and additive manufacturing heritage directly overlaps with Ursa Major's engineering DNA, and several Ursa Major leaders are SpaceX alumni.
• Blue Origin: Blue Origin is the second U.S. company (alongside SpaceX and now Ursa Major) to have proven and reflown a reusable liquid rocket engine. Its BE-series engines and large-scale liquid propulsion compete with Ursa Major's Arroway and Hadley lines for the same engineering talent pool and DoD/launch customers.

Emerging players

• Anduril Industries: Anduril is the peer most often cited alongside Ursa Major as a new entrant addressing solid rocket motor and broader defense industrial base gaps. Both are venture-backed, software- and manufacturing-centric, and building new categories of capability for the U.S. DoD.
• Hadrian: Hadrian builds additive-manufactured precision parts for aerospace and defense and has been publicly grouped with Ursa Major as a scaling U.S. AM supplier for national security hardware. While Hadrian focuses on machined components rather than propulsion, it shares the same industrial-base thesis and customer set.
