The Dutch aircraft designer
Frederick Koolhoven joined Armstrong Whitworth in 1914. He designed a series of aircraft that had his initials in their designation. The F.K.3 followed the basic layout of theRoyal Aircraft Factory B.E.2 c, which Armstrong Whitworth were building for theRoyal Flying Corps . It was designed as an improvement, with a simplified structure. Trials atUpavon in May 1916 proved that the F.K.3 had a better performance in some respects than the B.E.2c, although it had a poorer useful load. Armstrong Whitworth were given a contract to build 150 aircraft with another 350 being built by Hewlett & Blondeau Limited atLuton . Production F.K.3s had the pilot's and observer's positions reversed from that of the prototype (and the B.E.2), so that the pilot sat in the front seat and the observer in the rear, thus allowing the observer a much more effective field of fire, although in the event few F.K.3s were flown with armament.Operational Service
The F.K.3 was not adopted for use by operational squadrons of the RFC in
France , as the more capable F.K.8 and R.E.8 were both already in prospect. Only one overseas unit received the F.K.3 (which was 47 Squadron atSalonika ), all the other aircraft were based in theUnited Kingdom . Most of the aircraft were used for training until replaced by theAvro 504 .Military Operators
