| The F.K.9 two-seat fighter-reconnaissance quadruplane
was built by Sir W G Armstrong Whitworth & Co
Ltd as a private venture, and was initially flown in the
summer of 1916. Initial trials dictated a number of modifications,
including new wings with enlarged ailerons,
an enlarged fin, a redesigned engine cowling and increased
undercarriage track. In this form, powered by a
110hp Clerget 9Z rotary engine, and with a designated
armament of one fixed 7.7mm Vickers gun
and one free 7.7mm Lewis gun, the F.K.9
was officially tested in November-December 1916 at the
Central Flying School. A production contract for 50
examples of an improved version, the F.K.10, was
awarded.
