Listed roles are those for which the aircraft were being used during the war – many obsolete pre-war combat aircraft remained in use as trainers rather than in their original more familiar roles. Captured or acquired aircraft are listed separately as many were used only for evaluation while those available in large enough numbers were commonly used as trainers, while a small number were used for special operations, with exception of some Italian aircraft used sometimes in large numbers mostly as transports. A full list of aircraft from 1933–1945 can be found in the Reich Aviation Ministry's list of aircraft at list of RLM aircraft designations and a full explanation is at RLM aircraft designation system.
