Lieutenant Lily-Mae Fisher, 31, grew up in Virginia Water, Surrey, competing for her regional netball team and representing England in junior lacrosse and pole vault.
She attended Imperial College London to study for a master's in geology, graduating in 2016, when she joined the Officer Training Corps and University Air Squadron, where she discovered a passion for flying.
Upon completing her MSci, she worked as a geologist at British Petroleum for two years before commissioning into the Royal Navy in 2019.
She represented Great Britain at the European Age Group Triathlon Championships in September 2021 whilst also completing Elementary Flying Training.
During a break in flying training, she attended the All Arms Commando Course, becoming Britain's only serving female Royal Navy Commando.
Following this achievement, she worked as a Watch Keeper on Op ISOTROPE, the UK military's response to the Channel Migrant Crisis, coordinating Naval assets to find, secure, and recover vessels, with the primary aim of preventing loss of life.
Her death has been described as a "huge loss" to the Royal Navy, Force, and Squadron, and she was said to have thoroughly enjoyed her initial flying training, with a particular interest in the tactical elements, which led her to want to fly the Merlin Mk4 and join 846 Naval Air Squadron in 2025.
The Ministry of Defence added she had "been an inspiration to countless people, particularly young women, encouraging them to achieve their dreams, and it is clear that she had a very bright future as a naval aviator ahead of her."

Petty Officer Owen Green, 24, joined the Royal Navy in January 2022, beginning initial training at HMS Raleigh.
He demonstrated a consistently high level of professional competence and dedication throughout his career as an Aircrewman with 845 Naval Air Squadron.
Following initial training at HMS Raleigh and advanced aircrew courses at RNAS Yeovilton, RAF Shawbury, and RNAS Culdrose, he rapidly progressed through the ranks, achieving Leading Hand status in September 2025 before achieving his Aircrewman Wings in June 2025.
He completed his embarked aviation qualification aboard HNLMS Johan De Witt in October 2025, reflecting his operational readiness and adaptability in multinational environments.
He played a key role in major exercises such as Hades Warrior and Wyvern Tor 26, contributing to force tactical validation and operational preparedness.
His deployment on Operation Clockwork 26 was particularly notable as he logged the highest flying hours among his peers in demanding Arctic conditions.
This earned him his Arctic environmental qualification and established him as one of the squadron’s most experienced operators in extreme environments.
The MoD said throughout his service, he consistently demonstrated technical proficiency, operational effectiveness, and a commitment to continuous professional development, making a significant contribution to squadron capability and mission success.
