Siskin Click the name above to see prints featuring Siskin aircraft. Manufacturer : Armstrong Whitworth Production Began : 1919 Retired : 1932 Number Built : 485	Siskin The Siskin first flew in May 1919, powered by a Dragonfly engine delivering 270 hp (200 kW), rather than the promised 320 hp (240 kW). Despite the expectations piled on it, the Dragonfly proved to be a disaster, far less powerful than expected and very unreliable, being prone to overheating and catastrophic vibration, that would normally cause crankshaft failure within a few hours. Despite the engine problems, the Siskin displayed good performance and handling, outmatching its Dragonfly-powered contemporaries. In 1919, Siddeley-Deasy merged with Armstrong Whitworth, with the aviation interests becoming Armstrong Whitworth Aircraft. Siddeley-Deasly had inherited the design of the RAF.8 fourteen-cylinder radial engine and its designer Sam D. Heron, and by 1920 this engine, now known as the Jaguar, had been developed sufficiently to be a possible replacement for the Dragonfly. One of the prototype Siskins was fitted with a Jaguar, flying in this form on 20 March 1921. In 1922 Air Ministry Specification 14/22 was issued for an all-metal single-seat high performance landplane and one Jaguar-powered prototype was ordered from Armstrong Whitworth. As well as re-engining with the Jaguar, Major Green redesigned the Siskin with an all-metal structure, as the Siskin III. A contract for three production aircraft was placed on 13 October 1922 with a further six ordered on 26 January 1923 including one as a prototype of a two-seat variant. The Siskin III first flew on 7 May 1923,[11] with first deliveries to the RAF (six for evaluation) taking place in January 1924. The fighter was the first all-metal fighter in the British Royal Air Force. he first Siskin IIIs were delivered to No. 41 Squadron RAF at RAF Northolt in May 1924, quickly followed by No. 111 Squadron RAF. The Siskin III was popular in service, being highly manoeuvrable, although slightly underpowered. The improved Siskin IIIA was first delivered to No. 111 Squadron in September 1926. The Siskin was used by 11 RAF squadrons. The last operational RAF Siskins were replaced in October 1932 by Bristol Bulldogs. .
