This is a list of aircraft type numbers allocated by an institution under the direction of Heereswaffenamt (before May 1933) and the Reich Air Ministry (RLM) between 1933 and 1945 for German military and civilian aircraft and in parallel to the list of German aircraft engines. See RLM aircraft designation system for an explanation of how these numbers were used.
