Proxflyer

Proxflyer is a Norwegian defense technology company specializing in the development of advanced unmanned surface and sub-surface foiling vessels, headquartered in Oslo and with a US presence in Florida.

We design and manufacture the Sea Shadow SSX-300, a revolutionary platform offering unparalleled covertness, speed, and operational flexibility for maritime defense.

Proxflyer combines decades of experience in operator-focused unmanned systems – including the Black Hornet – with disciplined engineering and continuous improvement to deliver ready-to-deploy capabilities to allied defense customers. Our commitment to signature management – visual, radar, acoustic, and thermal – ensures near-invisibility in contested environments.

Sea Shadow’s four operating modes – foiling, surface, submerged, and waterjet – provide unmatched tactical adaptability for a wide range of mission profiles, from ISR and electronic warfare to covert resupply and offensive operations.
