Hawker Hurricane [SEP] Introduction
The Hawker Hurricane is a British single-seat fighter aircraft of the 1930s–40s that was designed and predominantly built by Hawker Aircraft Ltd. for service with the Royal Air Force (RAF). It was overshadowed in the public consciousness by the Supermarine Spitfire's role during the Battle of Britain in 1940, but the Hurricane inflicted 60 per cent of the losses sustained by the Luftwaffe in the engagement, and fought in all the major theatres of the Second World War. The Hurricane originated from discussions between RAF officials and aircraft designer Sir Sydney Camm about a proposed monoplane derivative of the Hawker Fury biplane in the early 1930s.
