Bristol T.T.A.

The Bristol Type 6 T.T.A was a British two seat, twin engine biplane designed in 1915 as a defence fighter, with two prototypes built but no production. The initials stood for twin tractor, and the Type 6 number was added retrospectively in 1923. It was designed to a War Office requirement for a local defence aircraft around compactness and a wide field of fire from both cockpits. The wings were three bay with the engines in rectangular nacelles between them, the gunner sat in the nose with two Lewis guns and the pilot behind the wing trailing edge had a rear pointing gun. Beardmore 120 hp engines were fitted; the first prototype was completed on 26 April 1916 and the aircraft were not liked.
