5. Supermarine Spitfire
Plane Type: Fighter
Fought For: Allies (Great Britain)
Complex Says: The Spitfire was how Great Britain won the Battle of Britain against the German Luftwaffe forces. It's also how the Royal Air Force fought Germany's V-1 rockets, thwarting and destroying more than 300 of them before they could hit their targets. Considering that the V-1 rockets that weren't intercepted killed 30,000 British civilians, that's quite a record. Four different armament suites existed for Spitfires over the course of the war. Spitfires were equipped with either eight 7.7mm machine guns, four 7.7mm machine guns and four 20mm cannons, or two 20mm cannons and two 12.7mm machine guns.
