Lieutenant Lily-Mae Fisher, 31, from Virginia Water, Surrey. Britain’s only serving female Royal Navy Commando.
Killed in training on 3 June 2026 when a Merlin Mk4 from 846 Naval Air Squadron crashed at Sourton Down, Devon.
The career arc was extraordinary. An MSc in Geology from Imperial College London in 2016. Junior international representative for England in lacrosse and pole vault. Two years as a geologist with British Petroleum before commissioning in 2019 into the Royal Navy.
During a break in flying training she completed the 16 week All Arms Commando Course, earning the green beret as one of only seven women in British military history to do so, and becoming the UK’s only serving female Royal Navy Commando.
She was killed on her final assessment of flying training. Her Pilot’s Wings were to be awarded in June 2026. She died alongside Lieutenant Commander Chris Gayson, 42, and Petty Officer Owen Green, 24.
