Book excerpt: The Hurricane Pocket Manual collates authentic period sources including pilot's notes and other Air Ministry publications to provide a unique guide to this iconic aircraft. The Hawker Hurricane was a British single-seat fighter aircraft that was designed and predominantly built by Hawker Aircraft Ltd for the RAF. Although overshadowed by the Spitfire, during the Battle of Britain the Hurricane accounted 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 that acted as interceptor-fighters, fighter-bombers (also called 'Hurribombers'), and ground support aircraft. Further versions known as the Sea Hurricane had modifications that enabled operation from ships. Some were converted as catapult-launched convoy escorts, known as 'Hurricats'. More than 14,583 Hurricanes were built by the end of 1944 (including at least 800 converted to Sea Hurricanes and some 1,400 built in Canada. The book collates a variety of pamphlets and manuals on the plane that were produced throughout the war for the benefit of pilots and others associated with the aircraft.
