| The first design by Frederick (Frits) Koolhoven after
joining the British Aerial Transport Company (B.A.T.),
the private-venture F.K.22 single-seat fighter flown in
September 1917 was of wooden construction with a
monocoque fuselage. Powered by a 120hp A.B.C. Mosquito
six-cylinder radial engine, it displayed sufficient
promise to win an official contract for a batch of six development
aircraft. The first and third of these were
powered by the 170hp A.B.C. Wasp seven-cylinder
radial (F.K.22/1) and the second by a 100hp Gnome
Monosoupape nine-cylinder rotary (F.K.22/2), the remaining
three eventually being completed as prototypes
for the F.K.23. The F.K.22/2, retroactively named
Bantam II, was the first to fly, commencing its trials in
December 1917 and being delivered to Martlesham for
official trials on 19 January 1918. Armament comprised
two synchronised 7.7mm Vickers guns, and
this prototype, later re-engined with a 110hp Le Rhone 9J nine-cylinder rotary, was eventually assigned to the
Central Flying School at Upavon.
