Digital Trends: Dubbed the Corrosion Resistant Aerial Covert Unmanned Nautical System — or CRACUNS for short — Johns Hopkins’ drone has the ability to reside for months underwater without deteriorating or decaying. by Rick Stella
'Once given the signal, the CRACUNS would then rise to the water’s surface and begin flight, capable of undertaking a variety of missions.
'Citing transforming desires from its backers, Johns Hopkins said it was compelled to manufacture a drone that could feasibly function underwater and in the air. To accomplish this, the APL worked closely with fabrication specialists at the university’s Research and Exploratory Development Department to develop a UAV body that wouldn’t require structural metal parts or machined surfaces.
'“Engineers at APL have long worked on both Navy submarine systems and autonomous UAVs,” said CRACUNS project manager Jason Stipes in a published press release. “In response to evolving sponsor challenges, we were inspired to develop a vehicle that could operate both underwater and in the air.”'
