Like many early monoplanes, the Deperdussin TT placed the observer in the forward seat, directly over the shoulder-mounted wings where visibility was at its worst. The type equipped two escadrilles but did not last long in service, re-equipping with Caudron G.3s in March 1915. When the war started, two of France's twenty-three escadrilles were based on the Deperdussin TT.
Experiments gun fittings were carried out with a couple of TTs by mounting a machine gun on the top of the cabane struts where a standing observer could fire over the propeller.
Sixty-three were produced in Russia by Dux and used as late as 1917. Belgium, Serbia, Turkey, and the UK each used a couple of TTs near the beginning of the war. The UK had a handful but most were removed from service before the war began.
