STARK
Country: Germany | Funding: $647.7M
STARK manufactures a bunch of drones for NATO countries. It's flagship drone Virtus is a long-range VTOL loitering munition, which can deliver precision strikes up to 130km in GNSS-denied environments. The company also produces Cascade (a tube-launched, man-portable loitering munition with a range of up to 100km), Gambit (a 6kg man-portable quadcopter designed for ISR and short-range strikes), Vanta (an unmanned surface vessel that comes in 13 and 20-foot variants. It’s primarily designed for ISR, but can be configured for go-boom missions). STARK also develops Minerva - C2 software that helps coordinate unmanned systems across all domains from a single ground station.

Saronic Technologies
Country: USA | Funding: $2.6B
Saronic develops advanced unmanned surface vehicles (USVs) that provide maritime security and situational awareness by combining best-in-class hardware, software, and artificial intelligence into a single, scalable, fully integrated platform. The company produces the Corsair (a 24-foot autonomous surface vessel), Mirage (a 40-foot vessel), and Marauder (a 180-foot cargo boat). Artificial intelligence and cross-platform data fusion enable multi-asset teaming. Digital twins accelerate learning and reduce risk prior to system validation in the physical world. Saronic operates its own shipyard in Franklin and plans to build another mega-factory.

HavocAI
Country: USA | Funding: $97.2M
HavocAI is an artificial intelligence company that offers maritime autonomy solutions to the defense and commercial markets.
5
Arc Boat Company
Country: USA | Funding: $150M
Arc Boats builds hybrid electric vessels: tugs, ferries, and electric motors for autonomous defense boats (ensuring stealth). Its integrated electric systems combine the propulsion system, energy storage, and software into a single, coherent platform. The electric motor delivers high instantaneous torque and flexible speed control for precise control in port, reducing downtime and lowering operating costs. They ensure efficient charging and more environmentally friendly operation for busy, repetitive schedules. Without fuel systems or complex transmissions, the electric propulsion system minimizes maintenance and downtime.
