The Hawker Hurricane is a British single-seat fighter aircraft that was designed and predominantly built by Hawker Aircraft Ltd for the Royal Air Force (RAF). Although largely overshadowed by the Supermarine Spitfire, the aircraft became renowned during the Battle of Britain, accounting for 60% of the RAF's air victories in the battle, and served in all the major theatres of the Second World War. The 1930s design evolved through several versions and adaptations, resulting in a series of aircraft which acted as interceptor-fighters, fighter-bombers (also called "Hurribombers"), and ground support aircraft. Further versions known as the Sea Hurricane had modifications which enabled operation from ships. Some were converted as catapult-launched convoy escorts, known as "Hurricats". More than 14,000 Hurricanes were built by the end of 1944 (including about 1,200 converted to Sea Hurricanes and some 1,400 built in Canada by the Canada Car and Foundry).
Finland bought 12 Mk I Hurricanes at the end of the Winter War, but lost two during the transit flight. The aircraft did not have much success (only 5½ kills). When hostilities began again on 25 June 1941, their use was quite limited, partially because they were worn out due to the scarcity of replacement parts available during the Interim Peace (13 March 1940- 25 June 1941) and subsequent combat flying. One Hurricane Mk IIB was captured from the Soviets during the war and flown by the Finnish Air Force.
