On the Axisside,it'svery few, Japan had a few sample airplanes from Germany,
at least one Bf-109E, Fw-190 and one Ju-87. Plans for both Me 163 and Me 262
are also stated to have been send there, the Me 163 clone is a Mitsubishe
Allied forces uded more planes in both theatres, Wildcats, Hellcats,
Spitfires, Hurricanes, Airacobras, Warhawk/Tomahawks, Mohawks, Lightnings,
Mustangs, Thunderbolts and Fireflys. The one important fighter I can't
remember being use in Europe is the Corsair, and the Hellcat was very
limited but the rest can fight both Zeros and Messerschmitts.
The Royal Navy's Fleet Air Arm used Corsairs to provide top cover during
Operation Mascot, the attack on the Tirpitz.
Grumman Avengers were also used by the FAA in Europe, so that's another
aircraft which can be added to the list.
British aircraft used in both theatres include the Blenheim, Beaufort,
Beaufighter, Barracuda, Mosquito, Fulmar and Seafire. The Blackburn Skua
was used the Far East, but was withdrawn from operations shortly before the
war started in the Pacific. The Fairey Swordfish was used on anti-shipping
patrols off the coast of Australia.
