The CRACUNS submarine Drone Can Swim For Months And Then Fly Away--Drone inayoweza kukaa ndani ya maji kwa muda wa mwezi mmoja na kuweza kuruka tena

The CRACUNS can hide in waiting at the bottom of the sea, ready to strike at a moment's notice.​

CRACUNS is the James Bond-esque spy drone of the future, a waterproof UAV that can survive two months in briny water intact. While fully submergible, CRACUNS can rise from the depths and take to the air. 

The vehicle, which carries the full name Corrosion Resistant Aerial Covert Unmanned Nautical System, is intended to be placed outside submarines where it can be deployed to the sea floor, lying in waiting for two months with a suite of surveillance gear. When it needs to be retrieved, it can re-surface and make its way back to the ship. 

CRACUNS was built by the Johns Hopkins University Applied Physics Laboratory, the same lab that built the New Horizons Pluto probe for NASA. The instrument payload is kept in a submergible container inside the drone body, while the exterior drone is protected by off-the-shelf parts, driving down the cost.
