Deperdussin TT

The Deperdussin TT was a French two-seat monoplane built by Société Pour les Appareils Deperdussin, the firm that later became SPAD. Introduced in 1912, it was widely used by the French military aviation service before the First World War, and in February 1914 a machine gun was trialled on one, although that installation did not enter service. A number flew with the Naval Wing of the British Royal Flying Corps, one of them fitted with floats and flown from Lake Windermere. Air arms listed as operators include those of Belgium, France, Paraguay, Portugal, Russia, Serbia, Spain, Turkey and the United Kingdom. Published specifications give a length of 7.92 m, a wingspan of 10.97 m, a gross weight of 725 kg and an 80 hp Gnome rotary engine for a top speed of about 114 km/h.
