CRACUNS sinks to new depths for sneaky snooping

cracuns topCRACUNS is a new drone that has been created by the John Hopkins University and it has some very particular stealth skills.

Just as nuclear submarines can lurk beneath the waves for months on end, laying in wait, the CRACUNS (Corrosion Resistant Aerial Covert Unmanned Nautical System) can do the same. I am guessing that it’s no mistake that the drone’s name is pretty close to that of the mythical sea creature, the Kraken.

One of the problems a submarine has it that it tends to give its position away when it sends up its periscope. Using a submersible drone could do away with that sort of behaviour.

The researchers at Johns Hopkins University have created a waterproof drone that can float up from the murky depths and then take to the skies to provide an aerial view.

The waterproof drone could be mounted to the outside of a submarine and deployed as needed for additional intelligence gathering — without putting the billion dollar vessel and its crew at risk.

Built using custom 3D-printed parts, the electronic components of the CRACUNS are either protected inside waterproof housings or, like its four electric motors, treated with a cheap off-the-shelf coating that keeps H2O at bay.

During testing the researchers at Johns Hopkins University’s Applied Physics Lab left the CRACUNS submerged in salt water for as long as two months without affecting its ability to take flight whatsoever.

This also means that the drones could be secretly dropped from passing planes into coastal areas and left underwater for months before being deployed to fly inland to gather intelligence.
