Editing Triplane (section)

===Zeppelin killers===
A few British designers pursued the triplane configuration in the anti-[[Zeppelin]] role. From 1915, [[Armstrong Whitworth]] developed the [[Armstrong Whitworth F.K.5|F.K.5]] and [[Armstrong Whitworth F.K.6|F.K.6]] prototypes. These were large three-seat types with twin engines and the middle wing of noticeably longer span than the others. Then in 1917 Blackburn produced [[Blackburn Triplane|their single-seat triplane]]. It was something of a throwback, featuring a pusher propeller and boom-mounted empennage in the manner of an earlier era. The arrangement was intended to allow fitting of an upwards-firing 2-pounder recoilless gun in the forward fuselage. Neither type progressed beyond the prototype stage.
