Development
The Hawker Hawfinch fighter aircraft was designed in 1925 as a replacement for both the Armstrong-Whitworth Siskin and the Gloster Gamecock fighters. The Armstrong Whitworth Siskin was a British Biplane single-seat Fighter aircraft of the 1920s produced by Armstrong Whitworth Aircraft. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout It participated in the competition to meet Specification F9/26, together with other aircraft manufacturers, that included nine different designs, of which five were built [1]. This is a partial list of the British Air Ministry (AM specifications for Aircraft. The Hawfinch first flew in March 1927 [2]. The Bristol Bulldog and the Hawfinch were considered to be the best of the aircraft evaluated, and were selected for more detailed evaluation. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The contract was finally awarded to the Bristol Bulldog, because of its slightly higher maximum speed.

Please see WikipediaWikiProject Aircraft/page content for recommended layout After the completion of the competition, the prototype Hawfinch was used for experimental purposes, being tested with single bay wings and with a twin float undercarriage.
Only one prototype was built.
Description
Twe Hawfinch was a two bay biplane with staggered wings. A biplane is a Fixed-wing aircraft with two main Wings The first powered heavier-than-air Aircraft, the Wright brothers' Wright Flyer The structure was the patented Hawker metal tube & "fishplate" system, with fabric covering. This article relates to the connection bar used in railways For the type of Greek pottery see Fish plate. It was the first all-metal fighter to be built by Hawker. The powerplant was initially a Bristol Jupiter VI engine, but this was changed to a Jupiter VII (450 hp) before the performance trials. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The armament consisted of two Vickers machine guns synchronised to fire through the propeller. The Vickers machine gun or Vickers gun is a name primarily used to refer to the water-cooled.
