X‑Bow Launch Systems Secures $105M Series B Led by Lockheed Martin and Top Aerospace Investors to Scale Advanced Rocket Technologies

X‑Bow Launch Systems, the Albuquerque, New Mexico–based aerospace and defense technology company specializing in advanced manufactured solid rocket motors (SRMs) and small launch vehicles, has secured substantial capital commitments through multiple funding rounds, including a major Series B closing in 2025 that underscores strong investor confidence in its trajectory.

In May 2025, X‑Bow announced the final closing of its Series B funding round, raising over $105 million in private capital to expand its production capacity, accelerate innovation efforts, and strengthen its role as a critical independent supplier within the U.S. defense and aerospace industrial base. The round was strategically led by Lockheed Martin, a global aerospace and defense leader, with significant participation from Razor’s Edge Ventures, Crosslink Capital, Balerion Space Ventures, Boeing Ventures, Bravo Victor Venture Capital, Upsher Management Company, Capital Factory, Arkenstone Capital, and Event Horizon Capital.

This Series B represents a continuation of X‑Bow’s success in attracting capital from both strategic corporate investors and venture partners who see promise in the company’s additive manufacturing‑based energetics technology and lean production model. Under the leadership of founder and CEO Jason Hundley and a growing executive team, X‑Bow is positioned to meet rising demand for domestically produced solid rocket motors used across defense programs and emerging commercial launch markets.

X‑Bow’s funding history stretches back several years and includes a mix of venture capital and strategic investments. In 2024, X‑Bow announced a Series B round raising more than $70 million, led by Razor’s Edge Ventures with participation from Lockheed Martin Ventures, Boeing Ventures, Crosslink Capital, and Balerion Space Ventures. That capital was aimed at accelerating growth of its hypersonic‑capable vehicles, strategic and tactical scale solid rocket motor programs, and the development of a “gigafactory” campus in Luling, Texas—designed to facilitate rapid, cost‑effective production of SRMs—along with expanded engineering capabilities.

Earlier rounds helped X‑Bow lay the foundation for these later expansions. In 2022, the company raised $27 million in a Series A round co‑led by Crosslink Capital and Razor’s Edge Ventures, with participation from Lockheed Martin Ventures and Broom Ventures. That financing supported development in additively manufactured energetics and the growth of its solid rocket motor and launch vehicle capabilities.

X‑Bow has also engaged in interim co‑investments to support specific strategic milestones. In 2023, it closed an interim funding round led by Lockheed Martin Ventures with involvement from Crosslink Capital, Razor’s Edge Ventures, Balerion Space Ventures, Bravo Victor Venture Capital, and Capital Factory. These funds helped X‑Bow satisfy matching requirements for a $60 million STRATFI award with AFWERX and the U.S. Air Force, enabling further development of its solid rocket motor technology and production infrastructure.

Taken together, X‑Bow’s funding reflects a blend of venture capital, strategic corporate backing, and defense‑aligned partnerships that have propelled its growth in a capital‑intensive sector. Investors such as Lockheed Martin and Boeing Ventures bring not only financial resources but strategic alignment with X‑Bow’s mission to diversify and strengthen the SRM industrial base in the United States—a priority underscored by government awards and collaborative efforts.

With more than $105 million raised in its latest Series B and participation from an array of high‑profile aerospace and venture investors, X‑Bow Launch Systems is building momentum as it scales production, enhances its technology portfolio, and positions itself at the intersection of national security requirements and next‑generation launch capabilities.

The company continues to leverage its technological strengths in additive manufacturing and modular rocket design to address evolving defense and commercial needs. X‑Bow’s funding success signals strong investor confidence in its ability to deliver innovative propulsion solutions and scale production to meet demand, at a time when the U.S. prioritizes resilient and competitive aerospace supply chains.
