Royal Navy’s Proteus Autonomous Helicopter Makes Maiden Flight

A one-off Leonardo demonstrator now enters trials to shape uncrewed anti-submarine roles within a future hybrid air wing.

Overview

  • The full-size aircraft lifted off from Predannack Airfield in Cornwall’s National Drone Hub after ground testing at Leonardo’s Yeovil site.
  • During two short sorties, it controlled its own flight systems autonomously under the safety supervision of test pilots on the ground.
  • Built under a roughly £60 million program, the prototype is intended for experimentation rather than immediate production or service entry.
  • Designed for maritime missions such as anti-submarine warfare and patrol, it offers a payload over one tonne with a modular bay sized for NATO pallet loads.
  • Leonardo and the Royal Navy say the program supports about 100 skilled UK jobs and places Britain among a small number of nations developing full-size autonomous rotorcraft.
