The most famous fighter aircraft used in the Battle of Britain were the British Hawker Hurricane and Supermarine Spitfire Mk I and the German Messerschmitt Bf 109 E variant ("Emil") single-engined fighters. Although the Spitfire has attracted more attention, the Hurricanes were more numerous and were responsible for most of the German losses, especially in the early part of the battle. The turn-around time (re-arm and refuel) for the Spitfire was 26 minutes, while the Hurricane's was 9 minutes, which increased its effectiveness.
