Westland Whirlwind
No.263 Sqn, RAF Exeter, 1941
This was a request from Nigel, which I was happy to do, being a fan of the type myself and I've drawn a fair few Westland types now.
This overlooked fighter was designed by W.E.W. Petter to meet Spec F.37/35 ( I've already drawn some of the competitors). Westland won the contract and 200 were ordered. The first of two prototypes flew on 11 October 1938. The armament was four 20mm Hispano cannon in the nose, at the time the heaviest firepower of any fighter (600lb, 272kg, per minute). It was powered by two 885hp Rolls-Royce Peregrine V-12 engines, a development of the successful Kestrel line. Deliveries began in July 1940 to 263 squadron. Production was delayed due to a shortage of engines (the Peregrine eventually being cancelled to concentrate on Merlin production) and only 8 were received by the end of 1940. The first 'kill', a Ar 196, came on 8 February 1941, although a Whirlwind was also lost. In September 1941, 137 Squadron was formed with the type and these were the only two squadrons to use them. A good low level performer, but poor at higher altitudes, it was soon used for fighter sweeps and light bombing carrying up to 1,000lbs. Only 112 of the 200 ordered were completed and the last was delivered in January 1942. 137 Sqn converted to the Typhoon in June 1943, 263 following in December. Only one Whirlwind survived the war, a hack with Westland which was scrapped in 1947. Today, a team is hoping to rebuild a Whirlwind using the original plans.
Trials included night-fighter use with 25 Sqn in May-June 1940, and the first prototype underwent tests with 12 Browning .303in MGs in the nose, and later a single 37mm cannon.
