Proteus, the Royal Navy's first full-size crewless helicopter, is one step from its maiden flight after successful ground trials at Leonardo Helicopters in Yeovil. The aircraft will serve as a demonstrator for the potential of autonomous helicopters in the Royal Navy's planned Hybrid Air Wing of tomorrow, utilising crewed and crewless air power. | Royal Navy
