The F4U Corsair is another most famous fighter and fighter-bomber of WWII, although it saw action mostly against the Japanese in the Theatre of the Pacific, therefore being primarily used by the US Navy and the Marines. This airplane in particular was specifically designed for aircraft carriers, being a naval aircraft in essence, although initial doubts over its performance on-board an aircraft carriers made it to serve initially as a land-based asset. It saw also action during the Korea War as a ground attack and Close Air Support (CAS) aircraft, and with the French in the Indochina, Algeria, and Suez Canal crisis. It also saw some service in the Atlantic during WWII, mainly with the British Fleet Air Arm, where reportedly provided air cover to the airplanes attacking the battleship Tirpitz, and served in the Indian and Pacific Oceans. The Corsair contributed to change the balance over the skies of the Pacific by shooting down many Mitsubishi A6M Zeros, although not as much as the Grumman F6F Hellcat.
