Sea Shadow
High speed, covert, multi-domain. Rapidly deploy payloads into contested areas while minimizing the risk of exposure.
Norwegian innovation for maritime defense
Proxflyer AS is a Norwegian defense technology company that develops advanced unmanned surface and sub-surface foiling vessels. With a multi-disciplinary team of engineers and developers, we bring proven experience in taking high-tech innovations from concept to field-ready products.
Our heritage includes developing the technology behind the Black Hornet nano UAS, and we apply that same approach — rapid prototyping, integrated engineering, and relentless field testing — to the maritime domain. Headquartered near Oslo with a US subsidiary in Florida.
Four modes for maximum flexibility
Seamless transitions between foiling, surface, submerged, and waterjet modes give operators unprecedented tactical flexibility.
Hull above water. Minimal wake, maximum efficiency and range.
90% submerged. Extended loiter for persistent surveillance.
Fully underwater. Electric propulsion eliminates acoustic signature.
Foils retracted, thruster as waterjet. Beach access and very shallow ops.
Invisible by design
Biomimetic hull, matte composite finish, minimal wake absorbed by sea state.
Carbon fibre composite hull designed to minimize radar cross section.
Electric propulsion, minimized cavitation, reduced hull-water interaction.
Efficient electric thrusters, low-power electronics, water cooling.
Built for the missions that matter
EO/IR sensors, SIGINT, autonomous target recognition and tracking.
ESM payloads and electronic warfare capabilities in a covert package.
Covert payload delivery and recovery with beach access via waterjet mode.
Relay station for ROVs, subsea sensors, and hydroacoustic systems.
Kinetic payload integration with different attack profiles from all operating modes.
Persistent low-signature tracking of vessels of interest.
Updates
Prototype-3 breaking Ice
Sea Shadow demonstrates ability to cut through thin ice and thicker layers of broken ice during extensive cold climate testing.
Prototype-3 foiling into the dark
First version of Prototype-3 completes initial tests with a completely new 3D-printed titanium foil system.
Testing in large waves
Prototype-2 completes a week of testing in northern waters, proving ability to operate in strong winds and large waves.
Proxflyer LARS
Testing begins on the new Launch And Recovery System, with initial tests using two operators and plans for single-person operation.
Build what others can't imagine
Multi-disciplinary team of engineers and developers in Oslo, Norway. We're growing fast and looking for people who thrive on hard problems.
