A small, submersible drone developped at John Hopkins’ research institute’s Applied Physics Laboratory (APL) can stay submerged for months, and instantly surface and launch on command without leaving a trace.
Watch this video describing APL’s Corrosion Resistant Aerial Covert Unmanned Naval System (CRACUNS).
The drone is fabricated from composite materials and coatings that prevents salt water corrosion. 3D printing enables production of complex, low cost structures necessary to endure the pressure at depths of hundreds of feet, yet be light enough for flight.
CRACUNS can carry various payloads to support different missions.
