About MetalCraft Marine
MetalCraft Marine designs welded-aluminium vessels around the speed, payload, seakeeping and launch requirements of patrol, firefighting, rescue and workboat customers. Its unmanned Over the Horizon Interceptor is a 25-foot waterjet vessel capable of approximately 43.5 knots, with an optionally crewed configuration for harbour transit and a hull-and-trailer package sized for shipment in a standard 40-foot container. Payload spaces support surveillance and other mission equipment.
The company supplies the vessel engineering and construction while autonomy can come from specialist partners. The first OTH-USV used a US Coast Guard research autonomy suite, while later configurations incorporated Huntington Ingalls Industries perception and autonomy software. MetalCraft is also producing ROMULUS-25 prototypes with HII for US Marine Corps evaluation, maintaining the same division of responsibility: MetalCraft builds and integrates the high-speed marine platform, while HII contributes its Odyssey autonomy architecture and mission software.

Timeline
Events
- 2026-08-11 - Demonstration - DIU recognizes successful completion of HII and MetalCraft ROMULUS-25 prototype programme
MetalCraft Marine supplied the 25-foot Watcher hull while HII integrated its Odyssey autonomous-control software, creating the ROMULUS-25 configuration evaluated through the programme. The two prototypes were delivered in December 2025 and subsequently demonstrated autonomous mission behaviours during at-sea testing for the U.S. Marine Corps. Successful prototype completion allows the Department of War to consider follow-on production through an Other Transaction Agreement without reopening a conventional competition.

HII said the two ROMULUS-25 autonomous USVs were delivered in December 2025 and supported sea testing. The vessels were awarded under a Defense Innovation Unit contract for smaller form-factor autonomous boat prototypes for the U.S. Marine Corps. HII said ROMULUS-25 is powered by its Odyssey autonomy suite and is designed for up to 1,000 pounds of payload and up to 1,000 nautical miles of range.

The 16.7-metre FireStorm 55 was manufactured at MetalCraft's Kingston, Ontario facility and entered Toronto waterfront service. Twin diesel engines and jet propulsion support rapid responses to fires, medical incidents, rescues and hazardous-materials events. The two new vessels expanded access to shallow and narrow waterways around Toronto's waterfront and islands.

The final Kingston 30 in the eight-boat contract departed MetalCraft Marine's U.S. facility for Virginia. The vessels were commissioned to support Navy spill recovery, vessel support and salvage missions worldwide. The aluminum tow boats paired an Iveco NEF 450 engine with an UltraJet 305HT waterjet and achieved 3,800 pounds of bollard pull in sea trials.
