Simplify's Take

What believers are saying

  • November 2025 Series E raised $100 million plus $50 million debt commitments.
  • March 2026 Hadley H13 hot fires and Draper flight tests validate production readiness.
  • July 2026 Navy MK 104 and Army hypersonics work expand booked defense demand.

What critics are saying

  • Defense contracting dominates revenue; any Pentagon re-prioritization hits demand fast.
  • Execution risk stays high: MK 104 production and HAVOC fielding need flawless scaling.
  • Anduril, Castelion, X-Bow, and incumbents compress margins; Ursa Major lacks launch dominance.

What makes Ursa Major unique

  • Additive manufacturing powers Hadley, Draper, and Lynx across liquid and solid propulsion.
  • February 2026 HAVOC bundles Draper and Lynx into one hypersonic weapon system.
  • Ursa Major spans engines, missile motors, and full-system integration, not single-product propulsion.

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.

Supported by the UAE Ministry of Defence (MOD) and the Tawazun Council for Defence Enablement (Tawazun), and organised by ADNEC Group, a Modon company, the pavilion serves as a unified showcase of the UAE's defence capabilities, bringing together the leading national defence entities under one roof to engage with global industry stakeholders and explore new avenues for collaboration. Throughout the day, EDGE Group held 19 meetings, Resource Industries held 14 meetings, and Emirates Cable Corporation Interconnect held 12 meetings. The collaboration between UAE national companies and international defence and security leaders at Eurosatory underscores the UAE's commitment to advancing global defence partnerships and fostering innovation. Meanwhile, ADNEC Group, which is participating at Eurosatory 2026 to promote national defence events, held 47 meetings at the pavilion and their stand regarding the 2027 edition International Defence Exhibition (IDEX), the Naval Defence and Maritime Security Exhibition (NAVDEX), the 2029 edition of Unmanned Systems Exhibition (UMEX), the Simulation and Training Exhibition (SimTEX), and the 2029 edition of International Exhibition for National Security and Resilience (ISNR). Several Memoranda of Understanding (MoUs) and agreements were signed at the pavilion. EDGE Group and EM&E Group, a leading Spanish group in defence and security innovation and technologies, signed an agreement to establish a joint venture in the UAE. Additionally, an MoU was signed between EDGE Group and Thermoteknix, a United Kingdom-based innovator in infrared thermal imaging, night vision, and augmented reality vision systems, serving defence and security. EDGE Group also signed an MoU with Ursa Major, an American aerospace and defence company manufacturing rocket engines and hypersonic propulsion systems. The UAE Pavilion welcomed several industry leaders and military delegations, including a delegation from the Brazilian Armed Forces, as well as a visit from Major General (Ret'd) Charles Beaudouin, CEO of COGES Events, the organiser of Eurosatory 2026. Their visits and tours of the pavilion, along with viewings of national products showcased by UAE national defence industries, reflect the quality and growing competitiveness of the UAE's defence sector on the global stage.
