The Deperdussin TT was a French mid-wing braced monoplane aircraft from 1914 the outbreak of World War I built in small numbers by Société Pour les Appareils Deperdussin or S.P.A.D.. The type's use by the French Air Force (then Aviation Militaire) was very brief due to its frailty and lack of weapons. In February 1914 an experiment was made to install a machine gun in the nose of the craft but it was not followed up.
Made by Société Pour L'Aviation et ses Dérivés.
