Deperdussin TT

The Deperdussin TT was a French monoplane built by Société Pour les Appareils Deperdussin, later to become S.P.A.D. Introduced in 1912, the type was one widely used by the French Air Force (then Aviation Militaire) before the First World War. 

In February 1914, an experiment was made to install a machine gun on the aircraft, but this did not see service.

A number were used by the Naval Wing of the British Royal Flying Corps, one being fitted with floats and flown from Lake Windemere.
