Can the Navy Finally Mass-Produce Autonomous Warships?
The Navy has spent years proving that unmanned ships can cross oceans and operate with minimal human control. The next test is different: can American yards repeatedly build them in useful numbers?
On September 29, the Navy moved its Medium Unmanned Surface Vessel effort from competition into production. Galliano Marine Services, HII and Saronic Technologies each received agreements covering 10 vessels. The Navy says the average procurement cost is approximately $40 million per vessel, placing the implied value of the 30-ship production tranche at roughly $1.2 billion.
The first deliveries are scheduled before the end of fiscal year 2027. That does not mean all 30 vessels arrive by then. It means the first production boats are expected to begin entering Navy hands within roughly a year of the award.
The harder question begins after that first delivery. The Navy's own long-range plan envisions a recurring MUSV production pipeline that could eventually require approximately 12 new vessels every year simply to sustain the planned force. Thirty hulls can establish a fleet. Sustained serial production determines whether that fleet can remain large.
The Navy did not pick one winner
Traditional naval acquisition often converges on one prime contractor and one standardized ship design. The MUSV marketplace is taking a different path. Three companies survived the first production competition, and all three received orders for the same number of vessels.
Saronic Technologies
Saronic's publicly disclosed MUSV is Marauder, a 180-foot autonomous vessel already in production and testing.
HII
HII received an order for 10 ROMULUS unmanned surface vessels and is using a distributed Louisiana production network.
Galliano Marine Services
The Edison Chouest-affiliated company won the third production agreement. Its selected configuration has not been publicly detailed.
The three-way split changes the industrial problem. Instead of requiring one yard to jump immediately from prototype work to a 30-vessel backlog, the Navy has created parallel production streams and retained competing designs.
That may also reduce dependence on a single hull, a single autonomy architecture or one shipyard's schedule. The tradeoff is configuration management. Multiple vessels can satisfy a common mission requirement while still using different machinery, software, maintenance procedures and supply chains.
The acquisition strategy changed almost as quickly as the vessels
The significance is not merely acquisition speed. The government deliberately shifted much of the early technical and production risk to companies willing to build real vessels before receiving large production orders.
The Navy's May shipbuilding plan stated that government payments under the marketplace model would follow demonstrated operational success rather than financing bespoke prototype design and fabrication. That approach favors companies capable of investing private capital before the government commits to serial procurement.
The autonomy had to survive more than a harbor demonstration
Phase I was designed around a demanding combination of speed, range, payload and autonomous navigation. Publicly reported requirements called for 2,500 nautical miles of travel at 25 knots in Sea State 4 while carrying as much as 25 metric tons of payload across at least two 40-foot-container positions.
The Navy also evaluated whether the boats could perceive surrounding maritime traffic, navigate in accordance with international collision-avoidance rules and conduct long-duration missions without continuous operator control.
At-sea gate
Six of the seven Phase I companies ultimately met the threshold needed to complete their prototype agreements. The three production winners received 10-vessel awards, while Leidos, PacMar and Sea Machines are receiving the $15 million success payment and joining the wider maritime marketplace. Birdon did not complete the required evaluation during the Phase I window.
This is as much a Gulf Coast production experiment as an autonomy program
The three awardees sit inside a maritime manufacturing region that spent decades building offshore crew boats, supply vessels, fast support vessels and other commercial workboats. The Navy is attempting to use that production culture rather than force every MUSV through the country's traditional large-combatant shipyards.
Saronic: build the factory around the vessel
Saronic acquired the former Gulf Craft yard in Franklin and is investing approximately $300 million in its expansion. The project adds more than 300,000 square feet, three new slips and a dedicated large-vessel production line.
Its Marauder is approximately 180 feet long. Saronic publishes a 25-knot-plus sprint speed, up to 5,400 nautical miles of range at a 25-metric-ton base load and payload capacity as high as 150 metric tons in other configurations.
Three Marauders were already under construction in Franklin shortly before the Navy production decision, while the first had moved into on-water testing.
HII: distribute the manufacturing network
HII has taken a different approach. Rather than concentrating every fabrication step at one major HII shipyard, it has paired its autonomy and systems business with Gulf Coast builders and suppliers.
As of September, four ROMULUS 151 vessels were under construction at Breaux Brothers and another was being built at Halimar Shipyard in Morgan City. Bayou Metal Supply & Manufacturing in Slidell also opened a dedicated production line to cut, bend, weld and assemble structural components for ROMULUS.
Breaux Brothers has publicly discussed a potential cadence of approximately one vessel every two months if demand supports the investment, equivalent to roughly six hulls annually from that yard alone.
Galliano: commercial workboat capacity enters the autonomous fleet
Galliano Marine Services, affiliated with Edison Chouest Offshore, represents the third production stream. The company comes from a Gulf Coast commercial maritime network with extensive offshore-service-vessel experience.
The Navy has not publicly disclosed the detailed configuration selected for Galliano's 10-vessel production tranche. That makes public comparison with Marauder and ROMULUS incomplete.
Its inclusion nevertheless reinforces the acquisition model: the Navy is buying from multiple existing industrial teams rather than waiting for one government-designed MUSV to mature through a conventional ship-development sequence.
A 30-ship order is not yet the same thing as a 30-ship production line
Serial manufacturing depends less on the number appearing in the contract announcement than on what happens to build intervals after hull one.
The final stage matters particularly for unmanned vessels. A conventional boat can be structurally complete while its autonomy stack, perception sensors, communications or software still prevent delivery.
Saronic has established a separate testing and commissioning location at Gulfport, Mississippi, for Marauder. HII is similarly separating portions of structural fabrication across several Gulf Coast facilities. These approaches attempt to keep final integration from blocking the physical shipbuilding line.
Long-term Navy planning requires recurring production, not one large batch
The May 2026 shipbuilding plan provides a much more demanding industrial picture than the September award alone.
The September 29 announcement covers 30 vessels, while the May plan showed 36 vessels funded in fiscal year 2026. Public Navy material available at the time of this report does not explain how the remaining six in that earlier planning quantity will be handled.
The more consequential number appears later. The notional shipbuilding plan buys 12 MUSVs annually beginning in fiscal year 2030 and continues using 12-per-year production assumptions through its long-range projection.
A different kind of fleet cycle
The same planning table reaches a peak MUSV inventory of 95 vessels in fiscal year 2032, then retires a large first cohort and eventually settles around 72 vessels.
From that point, the notional profile repeatedly purchases approximately 12 vessels while retiring approximately 12 vessels in the same year.
This implies that the Navy's planning model is built around continuous replacement rather than keeping individual MUSVs in service for the several-decade lifespans typical of major crewed warships.
The exact long-range quantities remain notional and the Navy explicitly says later-year figures can change. But the structure of the plan demonstrates why manufacturing cadence matters. An expendable or comparatively short-lived unmanned fleet only works economically if replacement vessels can keep moving through yards.
36 became 30, at least for this production announcement

September production awards
Ten vessels each awarded to Galliano Marine Services, HII and Saronic.
The difference should not automatically be characterized as a six-ship cut. The documents describe different moments in the acquisition process. The May figure was a planning and funding profile. The September announcement identifies the first specific production tranche after at-sea testing.
Until the Navy explains the remaining quantity, the defensible description is that 30 vessels are currently covered by the announced Phase I production agreements while 36 appeared in the earlier FY2026 procurement plan.
The Navy is already loosening the gate to bring more suppliers in
Only six days before the Phase I production awards, the Navy opened the second MUSV marketplace round.
Phase II broadens the allowable designs. Public solicitation material permits vessels up to 295 feet long and up to 5,000 metric tons displacement. It requires at least 10 days of unmanned operation, operation in Sea State 4 and survival in Sea State 6.
The Navy also removed two particularly restrictive Phase I features: the specific 25-knot high-speed requirement and the underway-refueling requirement.
| Requirement area | Phase I | Phase II direction | Industrial effect |
|---|---|---|---|
| Speed | 25-knot requirement | No equivalent fixed high-speed threshold publicly specified | Allows a wider range of commercial hull forms to compete. |
| Refueling | Underway-refueling requirement included | Requirement removed from the second marketplace round | Reduces integration complexity for new entrants. |
| Vessel size | Phase I clustered around medium commercial-derived vessels | Up to 295 ft and 5,000 metric tons | Creates room for substantially different hull designs. |
| Endurance | Long-range high-speed requirement | At least 10 days unmanned | Emphasizes sustained operation rather than one specific speed-range combination. |
| Sea state | Operational testing included Sea State 4 requirement | Operate Sea State 4, survive Sea State 6 | Maintains open-ocean survivability as a key threshold. |
| Competition | Seven Phase I selections | Rolling evaluations over several years | Keeps the supplier base open instead of permanently closing after one award. |
This may prove as consequential as the first 30-vessel order. A recurring marketplace gives the Navy a way to buy later production blocks from new suppliers or updated vessel designs without forcing every future MUSV into the exact Phase I configuration.
Five things can still prevent 30 orders from becoming sustained production
Configuration churn
Serial production depends on repeatability. If autonomy hardware, payload interfaces, machinery or Navy requirements continue changing faster than hulls move through the yards, each production vessel can begin behaving like another prototype.
Testing throughput
Three yards may be able to fabricate vessels faster than the Navy and industry can commission, certify and accept autonomous systems. Software and autonomy validation can therefore become a production constraint even when physical hull capacity is available.
Common support
Three suppliers increase competition and resilience but can also create separate spare-parts, training, software and maintenance ecosystems. The value of a family-of-systems model depends on how much commonality exists beneath the different hulls.
Demand continuity
Commercial-scale production investment requires predictable orders. A yard designed around 10 or 12 MUSVs per year can become inefficient if annual procurement repeatedly moves between surge buys and long gaps.
Acquisition litigation
Blue Water Autonomy and Saildrone filed separate Court of Federal Claims cases after being excluded from the first MUSV competition. Both allege the Navy failed to apply its own evaluation criteria correctly. The Navy has continued the program while the litigation remains unresolved.
The milestone is not hull 30
Several measurable conditions would indicate that the MUSV experiment has moved beyond a large initial order into repeatable serial manufacturing.
| Measure | Early production | Sustained serial production | Why it matters |
|---|---|---|---|
| Build cadence | Individual hull milestones dominate schedule | Predictable launch intervals measured in weeks or months | Shows the line is repeating rather than improvising. |
| Labor hours | High first-of-class learning load | Hours per vessel stabilize or decline | Indicates production learning is reducing effort. |
| Supplier flow | Parts expedited for specific hulls | Standard kits arrive to takt or station schedule | Prevents suppliers from setting the production rate. |
| Autonomy testing | Every vessel requires extensive bespoke troubleshooting | Software and sensor validation follow a repeatable acceptance process | Keeps commissioning from backing up completed hulls. |
| Annual output | Initial 30-ship tranche | Capacity capable of sustaining approximately 12 vessels annually under the current notional plan | Connects industrial capacity to long-range force structure. |
| Replacement | Fleet grows through new procurement | New hulls replace retiring cohorts without shrinking inventory | Tests whether an attritable fleet model can remain numerically stable. |
Three builders change the arithmetic
If one yard produced six MUSVs annually, a 30-vessel tranche would represent five years of output before accounting for testing or delays.
If three independent production streams each sustain four effective deliveries annually, the combined industrial base reaches 12 vessels per year, matching the Navy's current notional procurement rate for fiscal years 2030 and 2031.
The Navy therefore does not necessarily need one giant autonomous-warship factory. It needs enough independent, repeatable production lines whose combined output remains above annual fleet demand.
MUSV Serial Production Stress Test
This model tests whether a distributed production base can sustain a selected Navy procurement rate. It does not predict the actual performance of Galliano, HII or Saronic. It converts simple production assumptions into annual effective capacity and estimated time to complete a 30-vessel tranche.
