The US Navy is pushing its medium unmanned surface vessel ambitions into the water. Live demonstrations under the Medium Unmanned Surface Vessel (MUSV) Marketplace programme begin this month and run through October 2026, with seven companies competing for follow-on production contracts that could reshape how Washington fields its surface fleet.
Who is in the field
Saronic Technologies, Leidos, Sea Machines Robotics, Galliano Marine Services, PacMar Technologies, Birdon and Huntington Ingalls Industries (HII) are participating in the marketplace. Each company is receiving roughly $15 million to support testing, with successful platforms eligible for leasing arrangements or larger production buys. The cohort spans pure-play autonomy startups, naval architects and prime contractors — a deliberate mix the Navy says will surface different cost and capability trade-offs.
The Saronic, HII and Leidos angles
For Saronic, the marketplace builds on a hot streak. The Austin start-up only recently launched its 150-foot Marauder MUSV at its Franklin shipyard, after closing a $1.75 billion Series D at a $9.25 billion valuation. HII brings shipbuilding scale and integration know-how from the same yards that turn out Virginia-class submarines and Ford-class carriers. Leidos contributes pedigree from earlier ONR and DARPA autonomous programmes, including legacy work on the Sea Hunter family.
What success looks like
The MUSV marketplace is part of a broader Pentagon push to make half of the surface fleet unmanned in the long term. The programme builds on Saronic's earlier $392M Corsair production contract and on lessons from the Navy's Replicator initiative. Platforms that complete the demonstrations cleanly become candidates for missions that include intelligence, surveillance and reconnaissance (ISR), distributed maritime sensing, modular logistics and forward-deployed payload delivery.
The Pacific scenario is doing much of the work in shaping requirements. A defensible MUSV that costs a fraction of a destroyer, can absorb attrition and can be produced at scale is the kind of asset the Navy thinks it needs to deter coercion in the Western Pacific without bankrupting the shipbuilding budget.
