Experimentally equipped with three narrow-chord wings and a more powerful engine, the Pup led to the Triplane, which was used by just four squadrons of the RNAS during 1917, but became well known for its startling fighting qualities, put to best use by Raymond Collishaw's famous 'Black Flight' of 'Naval 10' (No. 10 Squadron RNAS). This flight was so called due to the black identification colour of the flight's aircraft, which in turn led to their naming as Black Maria, Black Prince, Black Death, Black Roger and Black Sheep. Such was the impact of this type that it spawned a large number of experimental triplane designs from manufacturers on all sides, although only the Fokker Triplane achieved any subsequent success.
