Simplify's Take

What believers are saying

  • November 2025 funding added $100 million equity and $50 million debt for scaling.
  • The July 2026 Navy MK 104 award extends Ursa Major deeper into SM-2 and SM-6 supply chains.
  • The July 2026 Army hypersonics partnership expands near-term demand beyond the Navy and AFRL.

What critics are saying

  • Federal customers dominate bookings, so one program loss hits revenue immediately.
  • MK 104 still needs critical design review and static fire before production revenue arrives.
  • A Draper or SRM test failure in 2026 could kill contracts and crush the $600 million valuation.

What makes Ursa Major unique

  • Ursa Major’s Lynx manufacturing standardizes solid rocket motors across multiple Navy programs.
  • On August 20, 2026, Longmont expanded avionics, in-space propulsion, and hypersonics capacity.
  • Draper’s 2026 supersonic flight validated storable, throttleable liquid propulsion for rapid missile development.

Ursa Major opens Longmont facility for 125+ employees, expands hypersonics and solid rocket motor production

Ursa Major has opened a new manufacturing facility in Longmont, Colorado, with capacity for more than 125 employees. The facility will produce avionics and in-space propulsion systems, featuring dedicated welding and manufacturing labs, an ISO 7 clean room, and an environmental test lab. The expansion allows Ursa Major to increase production of liquid engines, vehicle integration, and solid rocket motors at its Berthoud headquarters. CEO Chris Spagnoletti said the move addresses urgent customer demand, noting that the company's in-space propulsion delivers orbital maneuverability faster than legacy suppliers. Colorado Governor Jared Polis attended the ribbon-cutting ceremony on 20 August. Ursa Major now operates six sites across Colorado, Ohio, and Washington, D.C., following a Phase 1 manufacturing expansion completed in March.

Pentagon missile buildup changing the factory floor.

Pentagon missile buildup changing the factory floor. Startups are bringing software, robotics and manufacturing methods developed around commercial space into a defense industry under pressure to produce weapons faster HUNTSVILLE, Ala. - The Pentagon's push to replenish missile inventories is creating an opening for a new class of manufacturers that say the problem isn't simply a shortage of factory space. It is how those factories are built. Startups such as Machina, Hadrian and Freeform are applying software, robotics and highly automated production techniques to aerospace and defense manufacturing, challenging a model that has long relied on dedicated machinery, specialized tooling and skilled labor to make relatively small numbers of complex parts. Some of the new manufacturing technology grew out of the commercial space industry. At this year's Space and Missile Defense Symposium, Los Angeles-based Machina is displaying a 16-foot fuselage for a hypersonic vehicle that it manufactured for Ursa Major, a company that is expanding from rocket propulsion into complete hypersonic missile systems. Machina co-founder and chief executive Edward Mehr, who previously worked at SpaceX and Relativity Space, says the hardware is an example of how AI can be applied not to designing weapons, but to controlling the machines that manufacture them. "Missile programs are not constrained by design. They are constrained by production," Mehr told SpaceNews. Machina recently received a qualification contract from Lockheed Martin supporting the Joint Air-to-Surface Standoff Missile, or JASSM, a long-range cruise missile built for the Air Force. The agreement is significant for Machina because it puts an assembly made with the company's manufacturing process through qualification for an operational missile program. Lockheed is also an investor in Machina through Lockheed Martin Ventures. Mehr said manufacturing fuselage structures for hypersonic missiles has become "a big area of growth for us." Machina's manufacturing platform, called RoboCraftsman, uses robotic arms to progressively shape sheets of metal into aerospace structures. The company uses artificial intelligence to give robotic equipment more autonomy over how it performs a physical task. "Our use of AI and robotics allows us to build flexible manufacturing systems that can switch between processes and geometries while reducing the need for dedicated tooling," Mehr said. Mehr said traditional programs can require tens of millions of dollars in dedicated equipment and long setup periods before the first production hardware is available for testing. Machina's argument is that a programmable factory can compress that transition because much of the change resides in software rather than in a new set of dies and machinery. Equipment previously producing automotive hardware, for example, could be reprogrammed to begin making a missile structure after receiving the digital design, he said. "Under the traditional model, a significant design change or a new missile component can require another investment in tooling, equipment and production setup," Mehr said. "With our system, much of that change can happen through software rather than by building another dedicated manufacturing line." Machina is looking to demonstrate that its approach can consistently meet the tolerances, quality requirements and production rates demanded by major weapons programs. The company is preparing to scale. Machina raised $124 million earlier this year to help finance a new 200,000-square-foot U.S. factory intended to move the technology from lower-volume work into larger production runs. Its customers also include NASA and Toyota.

US Navy awards Ursa Major $10M to advance MK 104 rocket motor.

US Navy awards Ursa Major $10M to advance MK 104 rocket motor. The US Navy has awarded Ursa Major a $10-million contract to advance development of the MK 104 solid rocket motor as part of efforts to strengthen the country's missile propulsion industrial base. The award will fund the motor's progress through critical design review and static fire testing, bringing the program closer to production. To support the effort, the Colorado-based company will use its Lynx manufacturing approach, which is designed to produce adaptable solid rocket motors at a rate of hundreds of units annually. Jason Meredith, president of Solid Missile Systems at Ursa Major, said this development emphasizes scalability and faster processes as "solid rocket motor production has become the bottleneck in missile manufacturing." MK 104 program. The contract builds on a series of recent milestones for the MK 104. In September 2025, Raytheon awarded Avio USA a purchase order worth up to $26 million to perform engineering work supporting the Standard Missile program. Earlier, in 2024, the navy broadened its supplier base by awarding X-Bow contracts to produce MK 104 solid rocket motors using its proprietary manufacturing processes. In April of the same year, Ursa Major also partnered with the US Navy to develop a 3D-printed replacement for the MK 104 motor used in the SM-2, SM-3, and SM-6 missile families.

Ursa Major completes $25M solid rocket motor programme with US Navy and OSC

Ursa Major has completed its Solid Rocket Motor Manufacturing Pathfinder Program with the US Navy and Office of Strategic Capital. The cost-share programme concluded in February 2026 and represented a $25 million joint investment. During the programme, Ursa Major designed, manufactured, and successfully static-fired an HLG 10-inch SRM prototype. The company also developed a proprietary propellant for the motor, which met all performance objectives and burn duration requirements. The programme enabled Ursa Major to expand its SRM production capabilities through facility scaling and process improvements. The company refined its common, modular manufacturing process called Lynx, which uses Highly Loaded Grain technology to reduce tooling costs and lead times whilst increasing flexibility across multiple motor variants.
