On Friday, January 16, 2026, the United Kingdom’s Royal Navy and Leonardo UK (part of the Italian Leonardo Group) announced the first flight of the Proteus unmanned helicopter technology demonstrator. It is the first autonomous helicopter to have taken to the air in the United Kingdom.

The helicopter took off from Predannack Airfield, located near Mullion on the Lizard Peninsula in Cornwall. The flight was preceded by comprehensive ground tests completed a few weeks earlier at Leonardo UK’s facility in Yeovil, where the rotorcraft’s systems, sensors, and propulsion were tested.
During its first flight, Proteus was tasked with carrying out a short test in which it autonomously operated its own control systems, independently of the operator, all under the constant supervision and control of test pilots on the ground to ensure flight safety.
Predannack serves as a satellite airfield for helicopters based at the nearby RNAS Culdrose air station near Helston, but it is also a key site for the development of unmanned and autonomous systems, such as the National Drone Hub.
The Royal Navy has already introduced several types of unmanned aerial vehicles, including the BAE Systems/Malloy T-150 octocopters and the Peregrine (Schiebel Camcopter S-100) unmanned reconnaissance helicopter—but Proteus outshines them in terms of size, complexity, and, above all, autonomy.
The approximately three-ton unmanned helicopter, with a one-ton payload capacity, can carry various types of equipment thanks to an innovative modular payload bay and is made up of more than 40 components manufactured from advanced composite materials. It can operate in the maritime environment and in challenging weather conditions, such as high sea states and strong winds.
The UK Minister of State at the Ministry of Defence for the Armed Forces, Luke Pollard, said:
“This maiden flight is a proud moment for British innovation. Designed and built in Yeovil, Proteus supports skilled UK jobs while helping deliver the hybrid navy outlined in our Strategic Defence Review. Autonomous systems like this will be vital in protecting our seas without putting personnel in harm’s way.”
Commodore Steve Bolton, Royal Navy Deputy Director Aviation Future Programmes said:
“The successful first flight of Proteus is a significant step in delivering the Royal Navy’s maritime aviation transformation vision, and to demonstrating our steadfast commitment to investing in autonomy as part of a hybrid air wing. This milestone signals our intent to lead technological innovation, to enhance the fighting effectiveness of the Royal Navy in an increasingly complex operating environment, and to maintain operational advantage against evolving maritime threats.”
Nigel Colman, Managing Director Helicopters UK, Leonardo added:
“Proteus represents a step-change in how maritime aviation can deliver persistence, adaptability and reach – conducting the dull, dirty and dangerous missions in challenging environments without putting human operators at risk. As the UK’s only end-to-end rotary wing manufacturer it has been a pleasure working with the Royal Navy and seeing Proteus take off for the first time after being designed, developed, and manufactured at Leonardo’s Yeovil site is a fantastic milestone.”
The Proteus project was unveiled by Leonardo UK on January 7, 2025. It was developed in cooperation with the Future Capability Innovation (FCI) team of the Defence Equipment & Support (DE&S) logistics agency at the UK Ministry of Defence, as well as the Royal Navy. A 71 million GBP contract for the development of the helicopter was awarded in June 2022, and the first flight of the technology demonstrator was originally planned for mid-2025.
It was designed to carry out a range of missions, including support for anti-submarine warfare tasks, maritime patrol, and the use of information provided by a network of allied ships, helicopters, submarines, and detection systems tracking hostile underwater units. Its development program supports the Maritime Aviation Transformation (MATx) strategy, which covers the evolution of Royal Navy maritime aviation through 2040, including anti-submarine warfare capabilities.

This is aviation history.
The UK’s first pilotless helicopter, Proteus, has made its debut in the skies. 🚁
Designed by @Leonardo_UK, the autonomous helicopter made 2 short flights in Cornwall. It will serve as a testbed for future hybrid air wings.https://t.co/wauUT9petY pic.twitter.com/W9083fpf4C
