## Summary

The [US Navy](/ar/entity/us-navy) has down-selected seven Medium Unmanned Surface Vessel (MUSV) designs into
an at-sea prototype phase: Birdon, Galliano, [Huntington Ingalls](/ar/entity/huntington-ingalls), [Leidos](/ar/entity/leidos), PacMar,
[Saronic](/ar/entity/saronic) and Sea Machines. Each design that completes testing — running through October
2026 — earns $15M and follow-on production eligibility. The Navy plans to procure 36 MUSVs
in FY26 using ~$5B from the 2026 Reconciliation Act set aside for "marketplace"
contracting, all aligned to a "hybrid fleet" doctrine and the Pentagon's [Replicator](/ar/entity/replicator)
goal of thousands of autonomous platforms by 2027. Venture-backed [Saronic](/ar/entity/saronic) launched its
first Marauder [MUSV](/ar/entity/naval-drones) from design to on-water in under a year — a pace it
likens to WWII shipbuilding — directly challenging incumbent primes. The move follows the
Black Sea proof that cheap USVs can defeat conventional fleets.

## By the numbers

- 7 — MUSV designs in the at-sea prototype phase.
- 36 — MUSVs the Navy plans to buy in FY26.
- ~$5B — 2026 Reconciliation Act money earmarked for marketplace contracting.
- $15M — award to each design completing at-sea testing; follow-on production eligible.
- <1 year — Saronic's Marauder design-to-water timeline.

## Why it matters

The competition tests whether venture-backed shipyards can out-build the primes on the
metric that now matters — speed and volume of cheap autonomous hulls. It is the US answer
to both the Black Sea USV revolution and [China](/ar/entity/china)'s maritime-swarm push, and a wager that
[Replicator](/ar/entity/replicator) can field mass before a Taiwan contingency.

## What to watch

- At-sea test results by October 2026 and which firms win follow-on production.
- Whether Saronic's speed survives the move from prototype to scaled output.
- FY27 funding and how MUSVs integrate with crewed ships and counter-EW hardening.
