British Navy Unveils Full-Sized Autonomous Helicopter

Proteus will enable British forces to find, track, and, if necessary, take action against adversaries across vast areas of the ocean, the navy said.

The British Royal Navy on Jan. 16 unveiled its first full-sized autonomous helicopter, named Proteus, designed to patrol the seas and conduct anti-submarine warfare missions.

The Royal Navy said in a statement that the Proteus Technology Demonstrator’s successful maiden flight delivers on the commitments of the U.K. government’s Strategic Defence Review, which set out plans for a “New Hybrid Navy” in which manned and autonomous systems operate together and patrol zones, including the North Atlantic.
