MOD Boscombe Down (ICAO: EGDM) is the home of a military aircraft testing site, on the south-eastern outskirts of the town of Amesbury, Wiltshire, England.

An aerodrome opened at the Boscombe Down site in October 1917 and operated as a Royal Flying Corps Training Depot Station.

[5] Known as Royal Flying Corps Station Red House Farm, it trained aircrews for operational roles in France during the First World War.

[6] When the United States entered the war in April 1917, the Royal Flying Corps began training groundcrew and aircrew of Aviation Section of the US Army at the airfield.

[6] At the end of the war in November 1918, the airfield became an aircraft storage unit until 1920 when it closed and the site returned to agricultural use.

[6] The move marked the beginning of A&AEE Boscombe Down and aircraft research and testing at the station, a role which it has retained into the 21st century.

[18] The necessary facilities required for the specialist work carried out by the A&AEE were lacking at Boscombe Down, and its expansion resulted in many temporary buildings being constructed at the station in an unplanned manner.

On 26 September 1994, after an aircraft crashed on landing due to a nosewheel collapse, a USAF C5 Galaxy was redirected to the station.

[30][31] Following the creation of QinetiQ in 2001, a 25-year Long Term Partnering Agreement (LTPA) was established with the MoD, covering 16 sites including Boscombe Down.

[35] In April 2022, the RAF Centre of Aviation Medicine retired its two BAE Systems Hawk T.1 which were based at Boscombe Down.

QinetiQ will build one of Europe’s largest anechoic chambers that will be capable of housing large military assets such as Protector drones, Chinook helicopters, and F-35 fighter jets for testing against electronic warfare threats.
