The UK Royal Navy and Leonardo UK have achieved the first flight of the Proteus unmanned helicopter under autonomous control at Predannack Airfield in Cornwall. As the United Kingdom’s first full-size autonomous helicopter, Proteus is intended to operate alongside crewed platforms within the Fleet Air Arm’s future aviation framework.
During the flight, the aircraft navigated its own systems without onboard pilots, while test crews monitored its performance remotely. This flight represents the program’s shift from laboratory and ground-based testing to real-world airborne validation.
Predannack, a satellite site for RNAS Culdrose and home to the National Drone Hub, provided a dedicated environment for autonomous flight testing. The event was attended by engineers and officials from Leonardo, the Royal Navy, and UK Defence Innovation.
Proteus’ development traces back to 2013 with initial MoD funding under the Anti-Submarine Warfare Spearhead program. A £60 million contract awarded in 2022 enabled full-scale development and the creation of roughly 100 skilled UK jobs. The helicopter is among the first global examples of a full-size autonomous rotary-wing platform and will support future UK hybrid air wings and NATO maritime operations.
