Rectangular plan, covering an area of approx 5,704 square metres. Contemporary steel buttresses. West
elevation has continuous glazing below eaves, and 3 sets of sliding double doors. East elevation has

Historical note: The largest hangar built in Britain for use by fixed-wing aircraft during World War 1,
comprising 3 of the "F" type hangars which were introduced in 1917. Forms part of the most
outstanding group of early aircraft structures of this type in the British isles, ranging in size from the
1914 Belfast truss Canoe Hangar (qv) of 720 square metres in area, to the type "G" hangar (qv) of 1917
(972 square metres) and this example. Consequently, they manifest as a group the great advances made
in aircraft technology in the 1914-18 period. The base is also associated with the development of RJ
Mitchell's Merlin engine (used in the Spitfire), having been used for RAF speed trials in the inter-war
period and to accommodate British and Italian teams for the Schneider Trophy contest in 1929 and the
Supermarine and Gloster racers in 1931.
