The Hawker Hurricane was the first British single-engine fighter and the first single wing aircraft with retractable landing gear as well as an enclosed cockpit and 8 machine guns. The Hurricane went into operational service in December 1937 with the RAF 111 Squadron. The Hurricane is usually over looked as a major player in the BoB because of the Spitfire but 80% of the 1,792 German aircraft shot down were because of the Hurricane. There were 14,533 Hurricanes produced in all variants.
