While it was developed by Fairey as a reconnaissance fighter for the Royal Air Force, the only orders placed were for three for the Imperial Japanese Navy.
The Pintail was designed by F. Duncanson of Fairey Aviation to meet the requirements of the RAF Type XXI Specification, which was issued in 1919 for an amphibian reconnaissance fighter, competing with the Parnall Puffin.
In order to give a clear upwards field of view for the crew, the Pintail was fitted with an unusual tail unit, with the tailplane lying across the top of the rear fuselage and the rudder below the tailplane.
While the Pintail was not adopted by the RAF, three examples, similar to the Mark III, were sold to the Imperial Japanese Navy.
