Lee-on-Solent (HMS Daedalus)

Lee-on-Solent (HMS Daedalus) is a former Royal Naval Air Station located at Lee-on-the-Solent on the south coast of England in Hampshire. Established during World War I and developed through World War II and the Cold War, the site served as a key aviation, training and maintenance facility for the Royal Navy and Royal Air Force before its closure and transition to civilian uses. The station's long association with Fleet Air Arm aviation, experimental trials and anti-submarine operations made it a focal point for naval aviation policy, aviation engineering and coastal defence.

History

Originally requisitioned in 1917 during First World War expansion of naval aviation, the site became one of several Royal Naval Air Service and later Royal Air Force establishments created to support seaplane and shore-based aviation. In the interwar period the base expanded under programmes influenced by leaders such as Winston Churchill and implemented technologies emerging from organisations like the Aeronautical Research Committee and firms including Supermarine and Short Brothers. During Second World War operations the station contributed to coastal patrols, Air-sea rescue and convoy protection tasks coordinated with Admiralty strategy and the Home Fleet. Post-war restructuring saw Daedalus host Fleet Air Arm training and engineering units during the Cold War era alongside NATO exercises involving the Royal Canadian Navy and United States Navy. The 1960s–1980s period included shifts following reforms like the 1957 Sandys Defence Review and later defence cuts under successive Prime Ministers. The base closed to military flying in the 1990s amid Options for Change defence reviews and was progressively sold for redevelopment.

Facilities and Infrastructure

The air station featured runways, hangars, workshops and a Marine Engineering centre supporting aircraft such as the Supermarine Seafire, Fairey Barracuda, Hawker Sea Hawk and later rotary types like the Westland Wessex and Westland Sea King. Technical infrastructure included an Admiralty-run control tower, Royal Naval Air Engineering and Survival School facilities, a fire station, and a covered aircraft maintenance complex used by contractors such as British Aerospace. The site contained slipways and foreshore installations for seaplane operations, and fuel storage, ordnance depots and cold-weather stores for NATO interoperability. Adjacent accommodation and married quarters reflected service-family provision models similar to those at HMS Sultan and RN Air Station Yeovilton. During modernization phases, avionics and radar workshops integrated systems developed at Royal Aircraft Establishment and training ranges used equipment from Marconi and other defence suppliers.

Military Units and Operations

Daedalus hosted an array of units including Fleet Air Arm training squadrons, No. 1 Naval Airship School successors, and rotary conversion flights supporting carrier air group readiness with detachments to HMS Ark Royal and other carriers. It supported anti-submarine warfare squadrons, target-towing flights, and experimental trials linked to Admiralty Research Establishment programmes. Units based or embarked at Daedalus participated in operations during the Battle of the Atlantic, Operation Overlord support tasks, and Cold War NATO exercises like Exercise Mainbrace. Visiting units included Royal Air Force Coastal Command detachments and allied squadrons from the Royal Netherlands Navy and Royal Australian Navy during joint drills. The station also accommodated the Fleet Requirements and Aircraft Direction Unit and served as a hub for pilot conversion courses that prepared aircrew for service on ships including carriers and helicopter platforms.

Civilian Use and Development

Following military drawdown and final closure, parts of the airfield were transferred to civilian authorities and developers. The site was repurposed for mixed-use development including an aviation business park, leisure facilities, residential housing and small-scale industry, echoing redevelopment patterns seen at former bases like RAF Northolt and RNAS Yeovilton. Aviation heritage enterprises, flight training schools and light aircraft operators established operations in retained hangars; commercial tenants have included aerospace suppliers and restoration specialists connected to firms such as Rolls-Royce and BAE Systems. Local governance by Gosport Borough Council and planning decisions involving the Department for Communities and Local Government guided conservation and redevelopment, while transport links to Portsmouth and the M27 motorway influenced economic regeneration strategies.

Heritage and Memorials

The legacy of the station is commemorated by memorials and preservation groups; local museums and trusts document its role alongside exhibits on aircraft like the Fairey Swordfish and naval aviators who served at the base. Heritage initiatives involve organisations such as Historic England and local history societies cooperating with veterans' groups including the Fleet Air Arm Association to preserve artefacts, photographic archives and oral histories. Annual remembrance events and plaques mark connections to wartime operations and notable personnel linked to the site, while interpretive panels and conservation of surviving hangars contribute to the public record of naval aviation history in Hampshire and the wider Solent region.
