1 German Aircraft Designation System Between 1919 and about 1930 most major German aircraft manufacturers used sequential numbering systems to designate their models, with various types of prefixes. This led of the development of the baby 18 DFS to many duplications of numbers, e.
The list of numbers was maintained by the Technical Department, Division for Devolopment and Procurement of the RLM. Numbers were often allocated in blocks of five or more sequential numbers to the manufacturers, who were then free to use them for their new designs. For gliders, which used model numbers in a separate series, the prefix number was 108. BV in 1937 He – Ernst Heinkel A. Ju – Junkers Flugzeug- und Motorenwerke A. Upper-case suffix letters were used to designate major versions. The letters were normally assigned alphabetically, the first production version being model “A”.
Of course there were some exceptions, e. Additional numerical suffixes were used to designate subtypes of a version, with number 0 frequently being used for pre-series production runs. In some cases, this was not enough, and lower-case suffix letters were appended to distinguish between configurations of a subtype. Both suffixes were used for one-off and small series alterations to production models.
Rn for field or maintenance depot modifications, but there were numerous exceptions. The number following the V designated individual aircraft and not models, i. Me 262V3 was the third prototype of the Me 262 and not the third experimental model. The Vn suffixes are sometimes written with a dash, as V-n. The usage of “popular names” for aircraft was not very common in Germany, other than in Britain or the USA. C lists in sources , , and . Therefore there are often other more or less well known German aircraft with the same number, which are nevertheless not included in the official list.
