4. Vought F4U Corsair

Plane Type: Fighter
Fought For: Allies
Complex Says: Claiming an 11-to-one kill ratio, the Corsair is widely considered to be the most successful fighter of WWII. The Japanese nicknamed it “Whistling Death,” due to its distinct engine noise. The Corsair's inverted gull-wing design ably accommodated both the gigantic propeller and the short, stout landing gear that was an integral part of its design. To improve its aerodynamic efficiency, flush riveting and the new technique of spot-welding were used so that the plane's body was as smooth as possible, with nothing interrupting air flow. The armament suite included six .50-cal Colt-Browning M2 machine guns and either two 1,000-pound bombs or eight 5-inch rockets.
