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
