The Leonardo Proteus is an uncrewed rotorcraft developed by Leonardo Helicopters for the Royal Navy. A technology demonstrator aircraft is currently being developed and manufactured at the company's site in Yeovil, England with a first flight planned for mid-2025. The design features a modular payload bay which can be interchanged to meet different mission requirements, such as at-sea replenishment and anti-submarine warfare.

Overview

In August 2013, the Ministry of Defence (MOD) placed a two-year contract with AugustaWestland (now Leonardo Helicopters) worth £2.3 million to develop its Rotary Wing Unmanned Aerial System (RWUAS) concept, which is funded through its Anti-Submarine Warfare Spearhead programme. An SW-4 Solo uncrewed rotorcraft, a derivative of the PZL SW-4 Puszczyk helicopter, was used for trials and experimentation. The MOD had previously considered the US Navy's MQ-8 Fire Scout but ruled it out as it " not meet any endorsed UK capability need". A phase two contract, worth £8 million, jointly funded by Leonardo and the MOD, was signed in 2017 to continue development. A four-year contract worth £60 million was signed in July 2022 to develop a flyable three-tonne technology demonstrator, named Proteus, with the work to be carried out in Yeovil, England.

The final design of Proteus was revealed in January 2025. Its airframe is derived from the Kopter AW09 single-engine light helicopter and shares its shrouded anti-torque system and five-bladed rotor. It is designed to carry modular payloads which can be interchanged to meet different mission requirements, such as at-sea replenishment and anti-submarine warfare. It was developed through the use of a digital twin and artificial intelligence, with more than 40 components manufactured using advanced composite materials. Whilst it is being primarily developed for the Royal Navy, it will also be focused on exportability.
