Armstrong Whitworth F.K.3
![]()
When W G Armstrong, Whitworth & Co received a contract in 1914 to build B.E.2 aircraft for the Royal Flying Corps and the Royal New Zealand Air Service, it offered to design and build a simpler but equally efficient two-seat trainer aircraft instead. Similar in configuration to the B.E. in its initial state, with separated cockpits for pilot and observer, the Frederik Koolhoven designed F.K.3 construction started in August 1915.
