The U.S. Navy on May 22, 2026 selected seven contenders in its Medium Unmanned Surface Vessel (MUSV) marketplace to advance into prototype evaluation, accelerating the service's path to fielding a hybrid fleet of manned and unmanned ships.
What The Navy Announced
According to USNI News, the seven selected partners will complete at-sea demonstrations before October 2026, with the most promising designs eligible for Navy leasing or procurement in fiscal year 2027. The MUSV program targets a class of unmanned vessels between roughly 45 and 190 feet in length, intended for missions including intelligence, surveillance, reconnaissance and electronic warfare.
The marketplace structure—where multiple vendors compete to deliver real-world operational data—is part of the Navy's "Golden Fleet" approach to unmanned ships, replacing earlier, slower prototype-only acquisitions.
Why It Matters
Medium unmanned surface vessels are central to the Navy's plan to build a distributed maritime force capable of operating across the Indo-Pacific and other contested theaters. Allied navies, including the French Navy with its DANAE program and Norway in joint U.S.-Norway Arctic exercises, are moving in the same direction.
The MUSV decision lands in the same week as several other major unmanned maritime program announcements, including MARTAC's record-breaking 192-hour T38 mission and HII's delivery of ROMULUS-25 prototypes to the U.S. Marine Corps.
Industry Implications
Selection into the prototype phase typically clears the path to large multi-year defense contracts for at-scale unmanned vessels. Existing players in the broader USV market include incumbents like HII and BlackSea Technologies as well as venture-backed disruptors. The seven selected designs are expected to span a mix of large primes and newer entrants.
If the Navy moves into FY27 procurement on schedule, the program could become one of the largest unmanned naval acquisitions in U.S. history.
