The list of aircraft of World War II includes all the aircraft used by those countries which were at war during World War from the period between their joining the conflict and the conflict ending for them. Aircraft developed but not used operationally in the war are in the prototypes section at the end. Prototypes for aircraft that entered service under a different design number are ignored in favour of the service version. The date the aircraft entered service – or was first flown if the service date is unknown or it did not enter service – follows the name, followed by the country of origin and major wartime users. Aircraft used for multiple roles are generally only listed under their primary role unless specialized versions were built for other roles in significant numbers. Aircraft used by neutral countries such as Spain, Switzerland and Sweden (or countries which did no significant fighting such as most of those in South America) are not included.

Fighter aircraft

Biplane fighters

Fighters and fighter bombers

This table includes single-engined and single-seat fighters and ground attack aircraft

Heavy fighters (multi-engined or multi-seat), night fighters, dive bombers and torpedo bombers

Jet- and rocket- propelled fighters

Bomber and attack aircraft

Heavy and strategic bombers

Medium bombers and maritime patrol

Carrier-based naval bombers

Strategic and photo-reconnaissance aircraft

Strategic and photo-reconnaissance aircraft were frequently specially modified variants of high performance aircraft, usually fighters or bombers.

Seaplanes

Flying boats

Floatplanes

Transport aircraft

Transport planes

Transport gliders

Trainers

Primary trainers are used for basic flight training while advanced trainers were used for familiarization with the more complex systems and higher speeds of combat aircraft, and for air combat training. Multi-engined trainers were used to prepare pilots for multi-engine bombers and transports, and to train navigators, bombardiers, gunners and flight engineers. Most nations used obsolete combat types for advanced training, although large scale training programs such as the British Commonwealth Air Training Plan (BCATP) required more aircraft than were available and aircraft were designed and built specifically to fulfill training roles. Intermediate trainers were used in several countries but additional hours at the primary stage made them redundant.

Glider trainers

Primary trainers

Advanced trainers

Bomber trainers, target tugs and misc. trainers

Rotorcraft

Lighter than air

Rockets and drones

Prototypes

Prototypes were aircraft that were intended to enter service but did not, either due to changing requirements, failing to meet requirements or other problems. They may not have reached production before the end of the war but may have entered service post-war. If the aircraft was deployed to regular squadrons or used in an operational capacity other than evaluation, it should be listed above under its appropriate type. Napkinwaffe - paper projects and aircraft that first flew after the war are not included.
