Royal Naval Air Station Lee-on-Solent (HMS Daedalus) was one of the primary shore airfields of the Fleet Air Arm. First established as a seaplane base in 1917 during the First World War, it later became the main training establishment and administrative centre of the Fleet Air Arm. Situated near Lee-on-the-Solent in Hampshire, approximately four miles west of Portsmouth on the coast of the Solent at , the airfield closed for military use in 1996 and passed through several owners until 2014 when the current owners Fareham Borough Council bought the airfield and re-branded as Solent Airport. The airfield hosts the Solent Enterprise Zone. History Naval aviation began at Lee-on-Solent on 30 July 1917 when the Royal Naval Air Service (RNAS) opened the Naval Seaplane Training School as an extension to the seaplane training station at nearby Calshot. The school's first commander was Squadron Commander Douglas Evill. Initially, aircraft had to be transported from their temporary hangars to the top of the nearby cliff, then lowered by crane onto a trolley which ran on rails into the sea. Permanent hangars, workshops, accommodation and a new double slipway were soon constructed, however. Royal Air Force use On 1 April 1918, the RNAS combined with the Royal Flying Corps (RFC) to form the Royal Air Force (RAF) and the Lee-on-Solent Naval Seaplane Training School became an RAF station. Naval aviation training continued throughout the 1920s under the RAF with both Calshot and Lee-on-Solent providing training in operating seaplanes - initially using the wartime Short Type 184s and, from late 1921, the new Fairey IIID. On 1 April 1924, the Fleet Air Arm of the Royal Air Force was formed, encompassing those RAF units that normally embarked on aircraft carriers and fighting ships (including those at shore bases such as Lee-on-Solent). In 1931 the first grass airstrip at Lee was constructed to the west of the town, Lee-on-Solent became HQ RAF Coastal Area, and a major rebuilding programme ensued. On 14 July 1936, an expanded RAF Coastal Area became RAF Coastal Command, with the HQ remaining at Lee-on-Solent. Royal Navy use With the expansion of the RAF during the 1930s, however, Parliament decided that the Fleet Air Arm should transfer to the Admiralty. As a consequence, on 24 May 1939, HQ RAF Coastal Command moved to Northwood and Lee-on-Solent was commissioned as HMS Daedalus, becoming Headquarters of Flag Officer Air (Home). Second World War
