After a bit of a wait, here is my Westland Whirlwind Fighter.
This hefty twin engine was fast, by 1938 standards, hitting 136 mph. The cigar shaped body and framed tear drop canopy made it quite agile, earning the nick name 'Cricky'.
In 1936, when the RAF was looking for a fighter that was armed with four 20mm cannons, Westland jumped at the chance but had to go agains three other companies to win the contract; Supermarine, Hawker, and Gloster.
Both Westland and Gloster made twin engine design, while Supermarine had three designs. Westland and Gloster were given the go ahead, with Gloster dropping out soon afterwards. Westland's design had four cannons in the nose rather then on the wings, making it easier to shot down the enemy and had one other trick up it's sleave, it's range.
On a full tank, the Whirlwind had an approximate range of 800 Nautical Miles, far more then any other fighter in the RAF.
However due to the weak engines, rated at 880 HP each, the slow productions and the high landing speed, being 80 mph, only 116 were ever made.
Only two squadrens were ever equipped with this aircraft and they were removed from service in 1943, replaced by the Hawker Typhoon.
