Predannack, Cornwall, UK – Aviation history was made as the UK’s first fully autonomous full-size helicopter, the Proteus Technology Demonstrator, completed its maiden flight above Predannack airfield.

Designed and built by Leonardo for the Royal Navy, Proteus can operate autonomously while also working alongside crewed aircraft such as the Merlin Mk 2. The successful flight marks a key milestone in developing uncrewed aerial systems for future hybrid air wings.

The aircraft’s systems, sensors, and engines were thoroughly tested during weeks of ground running trials at Leonardo’s Yeovil facility before it lifted off. Engineers, technicians, and representatives from Leonardo, the Royal Navy, and UK Defence Innovation observed the flight, witnessing a new chapter in British aviation.

Proteus demonstrates the potential for autonomous helicopters to operate safely alongside traditional crewed aircraft, unlocking new capabilities for naval aviation.
