A team of US researchers has unveiled a new drone prototype that can lurk hidden under water and take to the sky on command.
A video of the drone in action was posted to the John Hopkins University Applied Physics Laboratory YouTube account on March 17.
The video shows the CRANCUNS (Corrosive Resistant Aerial Covert Unnmanned Nautical System) using its four rotor blades underwater to propel itself to the surface before soaring into the air.
The submersible drone has been built not only to be waterproof, but also to withstand water pressure and corrosive salt.
With its components housed in a dry-pressure vessel, CRANCUNS can remain submerged at depths of up to several hundred feet for at least two months, researchers said.
While the drone’s stealth and flying abilities lend itself to potential military applications, the technology could also be used to provide emergency aid to those stranded at sea.
CRANCUNS’ designers are yet to reveal when they expect it to be ready for public deployment, or whether they intend to make it available for commercial use.
