Colorado Hypersonics Startup Ursa Major Going Public in $2.3B SPAC Merger

Ursa Major, a Colorado-based defense startup specializing in hypersonics and solid rocket motors, announced plans to go public in a $2.3 billion deal. The agreement involves a merger with the publicly traded Bleichroeder Acquisition Corp., a special purpose acquisition company (SPAC) backed by Inflection Point Asset Management, which works to take companies public. The transaction is expected to close in the first quarter of 2027.

Company Background and Capital Trajectory

Since its founding in 2015, Ursa Major has raised more than $380 million in private capital while also garnering investment from the Defense Department to develop technology for solid rocket motors, space systems and hypersonics. The company has grown substantially, with more than 360 people across six facilities.

The company's 11-year trajectory reflects sustained investment in what CEO Chris Spagnoletti characterized as foundational work. "For eleven years, Ursa Major has invested in the hard work behind that outcome: propulsion, manufacturing, testing, qualification and flight. This transaction will help us turn that foundation into the production capacity our customers need," Spagnoletti said in a statement.

Strategic Motivation and Public Company Rationale

The shift to public ownership addresses a critical need for the defense industrial base: scaled production capacity for propulsion systems. Spagnoletti emphasized that "Becoming a public company aligns with our high standard of transparency and accountability, strengthening our ability to deliver responsibly for the warfighter over the long term." This framing positions the SPAC merger as more than a capital raise—it represents a strategic move to gain the balance sheet strength and governance infrastructure necessary to fulfill growing Defense Department procurement ambitions.

The timing reflects broader market conditions in defense technology. Public capital markets can provide sustained, substantial funding flows that private rounds, while substantial, cannot match. The $2.3 billion enterprise valuation signals investor confidence in Ursa Major's market position within the hypersonics and propulsion ecosystem, even as the company remains pre-profitability or in early revenue phases typical of advanced defense contractors.

Recent Contract Wins and Technical Achievements

Last month, the company announced a $10 million award from the US Navy to advance its MK 104 solid rocket motor through critical design review and static fire. This Navy contract represents a step forward in the qualification pathway for solid rocket systems, a category essential for both maritime propulsion and kinetic weapons applications.

On the liquid propulsion front, Ursa Major conducted its first flight test of its Draper liquid rocket engine this year as part of the Air Force Research Laboratory's Affordable Rapid Missile Demonstrator effort. This milestone in the ARMD program aligns with Air Force goals to accelerate the development and fielding of hypersonic munitions at reduced cost per unit.

The HAVOC Hypersonic System

In February, Ursa Major unveiled a new hypersonic missile system named HAVOC that the company plans to mostly manufacture in-house and could be built for around $3 million per unit. The HAVOC system exemplifies Ursa Major's approach to cost reduction through vertical integration—manufacturing most components internally rather than relying on a complex supplier network. This strategy, if executed successfully, could address a persistent challenge in hypersonic weapons: unit cost reduction that makes large-scale production feasible for military budgets.

The publicly stated per-unit cost of approximately $3 million represents a significant competitive advantage in an emerging market segment. As hypersonic systems transition from research and development into operational inventory, affordability becomes central to procurement decisions. Ursa Major's manufacturing-forward approach contrasts with traditional defense contractors that rely more heavily on integrators' roles.

Market Context and Defense Industrial Demand

The merger reflects sustained and growing Defense Department demand for domestic propulsion capabilities. The U.S. military is prioritizing both hypersonic weapons development and assured access to solid and liquid rocket motors for space launch and missile applications. Ursa Major operates at the intersection of these priorities, positioning itself as a supplier capable of delivering across multiple platforms.

Defense spending on hypersonics has accelerated over the past five years, driven by both operational requirements and strategic concerns about peer-competitor capabilities. Similarly, the Pentagon's emphasis on assured access to propulsion manufacturing—particularly solid rocket motors—reflects concerns about supply chain vulnerability and dependence on international suppliers. Ursa Major's Colorado-based operations, multiple facilities, and demonstrated production capability align with these policy priorities.

The SPAC merger also reflects the maturation of the defense tech financing ecosystem. While SPACs faced significant skepticism and regulatory scrutiny in consumer and tech sectors, defense-focused SPACs continue to attract institutional capital, particularly when backed by firms with established relationships in the sector. Inflection Point Asset Management's backing signals confidence that a public Ursa Major can satisfy both institutional growth expectations and Defense Department procurement requirements.

Path Forward and Production Scaling

The first quarter 2027 close date provides approximately 12 months for deal completion and integration planning. During this period, Ursa Major will need to prepare for the governance, compliance, and transparency requirements of public ownership while simultaneously ramping production on Navy and Air Force contracts. The CEO's emphasis on "production capacity" suggests the company views capital from the SPAC merger as directly enabling manufacturing expansion—potentially new facilities, equipment, or workforce growth across its six existing locations.

The success of this merger will be measured not only by stock performance but by the company's ability to deliver contracted systems on schedule and budget while improving per-unit costs as production volumes increase. For the Defense Department, Ursa Major's transition to public ownership represents a consolidation of emerging propulsion capabilities into a company with sufficient scale and capital to serve as a reliable, long-term supplier across multiple mission areas.
