The Hawker Hurricane was a combat aircraft of the 1930s and 1940s, designed by the British aircraft manufacturer Hawker Aircraft Ltd. The Hurricane was one of the principal combat aircraft that defended the United Kingdom during the Battle of Britain. This fighter plane played a pivotal role in the Second World War, primarily serving with the Royal Air Force, Royal Navy, Royal Canadian Air Force and Soviet Air Force. The Hurricane was mass-produced, with over 14,000 examples manufactured from 1937 to 1944. The Hurricane was produced in the United Kingdom and in Canada, with 1,451 examples built at the Canadian Car & Foundry plant, which was located in Fort William (now Thunder Bay), Ontario. Hurricane production in Canada lasted from 1938 to 1943 and was overseen by Elsie MacGill, the first woman in Canada to earn a master’s degree in aeronautical engineering. MacGill was popularly known as the “Queen of the Hurricanes” for overseeing the rapid production of the aircraft. At the height of production, the Canadian Car & Foundry plant produced 15 new aircraft each week.
