Armstrong Whitworth A.W.16

08/31/2010. Remarks by Johan Visschedijk: "The A.W.16, Armstrong Whitworth contender to the N.21/26 (naval fleet fighter) formula, appeared in 1930 and was a well-proportioned biplane conceived by J. Lloyd. The A.W.16 was designed also as a private venture to conform to Specification F.9/26 (day-and-night fighter and interceptor).

S1591 was the naval version, with its 540 hp geared and supercharged Panther IIIA engine surrounded by a Townend ring, the exhausts being of the stub type. Armament comprised two 0.303 in (7.7 mm) Vickers machine guns. Extensive tests were carried out on the machine at the A&AEE for some two years and resulted in modifications being made to S1591 which included (as seen in the photo) deletion of the horn balance on the rudder, the provision of a new fin which extended forwards and was of increased area, and the removal of the inner ring of the Townend cowling from the front of the engine.

The second (private venture) prototype, initially carrying the 'Class B' marking A-2 (c/n A.W.722), was later registered G-ABKF. It had its Panther IIIA replaced by a 565 hp Panther VII during the course of protracted trials at the A&AEE in 1933. Eventually the aircraft went to South Africa in Alan Cobham's circus. In all eighteen aircraft were produced, of which at least six were delivered to the Chinese Kwangsi Air Force, another ten were sold abroad to undisclosed customers."
