The 1915 Blackburn TB was a long-range twin-engined anti-Zeppelin floatplane. Technically a fighter. This was Blackburn's first twin-engined aircraft (TB standing for Twin Blackburn), but the rear fuselages and tails came from the BE.2c, then being licence-produced by Blackburn.
Designed for a pair of 150hp Smith radial engines, the TB was built with 100hp Gnome Monosoupapes giving a third less power. Its war load was 32kg of steel incendiary darts. The TB's were to climb above enemy airships where the observer would throw the darts at them in the hope of causing and igniting a fatal gas leak. The TB had no other armament.
