Westland Whirlwind Heavy Fighter / Fighter-Bomber Aircraft
Impressive when it appeared in the late 1930s, the Westland Whirlwind was all but outmoded by 1943 and primarily doomed by its choice of engine.

The Westland Whirlwind became a capable twin-engined, heavy fighter design that might have seen even better service numbers were it not for its selection of Rolls-Royce Peregrine engines. Originally slated to utilize the Rolls-Royce Merlin, the Whirlwind platform was instead relegated to using the underpowered Peregrine for nearly all Merlin stocks were directed to Supermarine Spitfire and Hawker Hurricane fighter production. As a result, the Whirlwind would break into military aviation with much promise but become an obsolete design as soon as June 1944 - replaced by the more capable Hawker Typhoon types in service. Total production of Whirlwinds netted just 116 units.
The Whirlwind was given an identifiable design with two underslung engine nacelles mounted under low-wing monoplane assemblies. While this elevated cockpit viewing for improved situational awareness, the pilot's vision was still obstructed by the wings and engine housings while also seated aft of a long nose assembly. The fuselage was tubular in its general shape with the tail unit of a T-style arrangement fitting a pair of horizontal planes to either side of a single rudder. Space in the nose section was reserved for a battery of 4 x 20mm cannons. The undercarriage continued the accepted "tail-dragger" three-point form featuring two main landing gear legs and a tail wheel. All were retractable into the airframe.
