Proxflyer is a Norwegian defense technology company developing unmanned surface and subsurface vessels designed for reconnaissance, surveillance, electronic warfare, and covert maritime operations. Its flagship platform, Sea Shadow, can transition between foiling, surface, submerged, and shallow-water modes, giving operators flexibility in environments where conventional vessels and aircraft face limitations. The company’s leadership team draws on experience from the development of the Black Hornet nano drone, and Proxflyer has received support from both private investors and the Norwegian Ministry of Defense. With operations in Norway and Florida, it is part of a growing group of defense startups focused on autonomous maritime systems.
