The Marine Corps is turning to three commercial boatbuilders to deliver a cheaper, faster autonomous resupply craft, and one of them has never worked for the Pentagon before. The Defense Innovation Unit has picked Rudder Industries, Saronic Technologies and Sea Machines Robotics to prototype the Autonomous Low Profile Vessel (ALPV), a semi-submersible drone boat meant to haul supplies to Marine units scattered across contested coastal waters. DIU announced the three prototype contracts on Monday, November 9, after a competitive solicitation earlier in the year.
DIU did not disclose dollar values for any of the three awards, and it has not said how many boats each company will build. According to Autonocion, the announcement went out on DIU's X account; Ocean News & Technology published its text.
Why the Marines Want a Faster Path to a Low-Profile Resupply Boat
The ALPV concept is not new to the Corps. DIU's announcement says the Marines "previously prototyped several ALPV variants, but we must move faster while reducing costs." The unit framed the project as a way to bring in commercial autonomy and vessel designs.
"The DIU ALPV project opens the aperture to best-in-class commercial autonomy solutions and vessel designs while delivering superior capability to Marine operators," the announcement states. It sums up the objective in one line: "The ultimate goal: Rapid prototyping and fielding at scale."
The design lineage is unusual for a military program. Low-profile vessels ride so low in the water that radar and lookouts pick up little of the hull, the same trait that made them popular with drug smugglers. Brig. Gen. Simon Doran, then the Corps' director of strategy and plans, acknowledged the resemblance. "Truth be told, this is just a narco boat," he said, in remarks Autonocion reported DefenseScoop resurfaced in March.
Several Marine Corps and Navy organizations are involved. According to the DIU text, government counterparts include PAE Marine Corps' Capabilities Development and Force Integration Directorate (CDFi), the Marine Corps Warfighting Laboratory/Futures Directorate, DRPM RAS, and the Naval Sea Systems Command (NAVSEA) Combatant Craft Division.
What the ALPV Solicitation Demands: 18,000 Pounds, 2,000 Nautical Miles
The performance bar set in DIU's March solicitation is well above what the Corps fields today. According to Autonocion's reading of the solicitation, each boat must carry at least 18,000 pounds of supplies, including bulk liquids such as fuel or water. It must cover 1,000 to 2,000 nautical miles fully loaded in sea state 5, hold at least 12 knots loaded in sea state 4, and survive sea state 6. It should also be able to loiter for up to 96 hours at slower speeds. Autonocion notes these are requirements, not specifications any of the winners has yet demonstrated.
Several requirements reflect the contested environment the boats will operate in. DIU wants operators to be able to scuttle the vessels remotely so a captured boat does not fall into enemy hands. Each company must also prove its boat can determine its position when GPS is jammed or unavailable, and show that before prototyping ends. Navigation must handle busy waterways and ports using the military's M-Code GPS and active sensors, with a fallback to passive sensors under emissions control.
Logistics drive one more line in the spec: each boat must come with a trailer that a regular commercial semi truck can pull. That requirement suggests a vessel the Marines could move by road and launch from wherever they need it, rather than one tied to a ship or a specific port.
Autonocion reports that the solicitation gives each company 180 days from its award to demonstrate a working boat. If the clock started at the November 9 announcement, that puts demonstrations around early May 2027, although DIU has not said when the clock started for each company.
How Sea Specter Sets the Baseline for Saronic, Sea Machines and Rudder
The Corps' current low-profile boat is the Sea Specter, a semi-submersible designed by Leidos and its Gibbs & Cox subsidiary. Autonocion, citing WorkBoat, says the Sea Specter is rated for about 10,000 pounds of cargo and cruises at 8 knots. The ALPV targets nearly double that payload and a 12-knot loaded speed.
The three selected firms bring different track records:
- Sea Machines Robotics already has a foothold in the program. Its SM300 autonomy system drives the Marine Corps' current low-profile boat, according to WorkBoat as cited by Autonocion.
- Saronic Technologies has been winning naval autonomy work. In September, the Navy picked Saronic as one of three builders for its medium drone ships, Military Times reported, per Autonocion.
- Rudder Industries is the newcomer. DIU describes it as a first-time DoD partner. Autonocion, citing Defense WarRoom, reports it is a marine manufacturer based in Portland, Maine; the DIU text itself does not say where the company is located.
The mix gives the government three different starting points: an incumbent autonomy provider, a Navy drone ship builder and an entrant with no prior defense work, all working to the same requirements.
What It Means for Contractors
The ALPV awards show DIU continuing to pull Marine Corps logistics programs toward commercial vendors and prototype agreements. Rudder Industries' selection matters most for firms outside the defense base: a company with no prior DoD work won a slot alongside an established autonomy provider and a Navy drone ship builder. Small marine manufacturers that can meet hard performance specs should watch DIU solicitations closely.
The requirements also suggest where subcontracting demand may land. GPS-denied navigation, M-Code receivers, passive sensing under emissions control, remote scuttling and tamper resistance all call for specialized suppliers. Builders of trailers, bulk-liquid cargo systems and semi-submersible hulls fit the spec as well. Prime vendors will likely need partners in each area to close the gap between today's Sea Specter and an 18,000-pound, 12-knot boat.
The phrase "fielding at scale" is the signal to track. DIU has made scale the stated objective, so the 180-day demonstrations could shape who supplies the Marines' autonomous resupply fleet. With no dollar values disclosed, the size of that opportunity remains unknown, but the program now has three vendors working against the same clock.
