Between 1917 and 1996 the site was RNAS Lee-on-Solent (HMS Daedalus), a Royal Naval Air Station that trained crews and engineers as part of the
Royal Navy's
Fleet Air Arm and earlier as part of the
Royal Air Force and
Royal Flying Corps. In 2003 it was the subject of much controversy over the proposal to use a small part of it as a refuge for asylum-seekers. In March 2006 the site was split, with ownership of the central area including the runways transferred to the
Maritime and Coastguard Agency (MCA) who have continued to use it as a base for their air sea rescue helicopters.
Hampshire Constabulary's fixed wing aircraft also continued to use the airfield. The outlying areas, including the former accommodation and technical area and surrounding land, hangars, and dispersals, were transferred to the South East England Development Agency (SEEDA). In April 2006, Gosport and Fareham Borough Councils issued a joint Planning Statement for Daedalus stating that "There should be provision of leisure and community facilities which could complement existing facilities to the benefit of local residents" and "Future development should seek to maximise the benefit of the existing runways for general and
private aviation use." In April/May 2006, whilst conducting repairs to the runway, building crews discovered a giant unexploded
land mine over 60 feet long that had been placed underneath the runway in the 1940s to cripple the airfield's operational capabilities in the event of a German invasion. The bomb (along with 19 others subsequently discovered) was scheduled to be removed in September 2006. The work was completed on 24 October 2006. During its RN ownership the airfield had been used for a variety of groups, including the Portsmouth Naval Gliding Club (PNGC). The Lee Bees Model Flying Club, The Tigers Children's Motorcycle Display Team and two flying schools, and a number of privately owned aircraft were based at the airfield. When the RN moved out in 1996, operational management of the airfield was taken over by Hampshire Police Air Support Unit (HPASU). This management continued until October 2010, with HPASU being tenants of the MCA, which is an Executive Agency of the
Department for Transport. In October 2010 Hampshire Police Air Support Unit was closed and its tasks taken over by the newly formed
South East Air Support Unit covering Hampshire, Sussex and Surrey from bases at RAF Odiham and Shoreham Airport. On acquiring their land SEEDA stated "The lack of availability of serviced employment land and new business space has been identified as an important requirement in South Hampshire. Our intention is that development of the site will focus on new aviation and marine related businesses, exploiting access to the existing runways and the Solent. Plans are to create a quality business location that will attract inward investment and provide accommodation for start-up, growing and established businesses". Aviation-related businesses, including an aircraft maintenance organisation, a microlight aircraft manufacturer and a flying school, became tenants of SEEDA in 2006, as did the owners of around 50 aircraft based on the site. The aerodrome is strategically important. The growth of commercial air transport at
Southampton Airport some years ago left it with no capacity for
general aviation (GA) aircraft. This leaves Lee-on-Solent as the only airfield in southern Hampshire with a hard runway available for general aviation, the nearest alternative in Hampshire being
Farnborough Airfield. On 18 October 2007, users were given 30 days notice by the Airfield Manager that the aerodrome would be closed to all existing users except MCA, HPASU and PNGC from 16 November 2007. The closure was successfully challenged by Lee Flying Association which worked with other agencies such as the
Civil Aviation Authority and
AOPA to develop new operating procedures, an Airfield Manual and an air-to-ground radio service and the airfield is now operating as a licensed
general aviation airfield. In May 2008 the closure decision was reversed. From 1 April 2011, the airfield was leased to the British aircraft manufacturer, Britten-Norman under its airfield operations subsidiary, Fly BN. Britten-Norman established corporate offices at the Daedalus Airfield site as well as a manufacturing base for its subsidiary Britten-Norman Aircraft and MRO facilities for two other subsidiaries, BN Defence and BN Aviation. In 2010 the
Regional Development Agencies were abolished and ownership of the land owned by
SEEDA was transferred to the Homes and Communities Agency Now managed by Fly BN on behalf of the airfield's new owner, the
Homes and Communities Agency, the airfield was prepared for licensed operations. In August 2011 the government announced that the airfield would host an
enterprise zone named the Solent Enterprise Zone. ==Current use==
