Bit offtopic: As well as general use, a lot of thesed are used to classify Soviet/Russien submarines from a NATO point of use.
Even more off topic:This is quite interesting (to me at last) in that NATO has used prefix schemes for bombers, fighters etc. (for example Bear (bomber), Fishbed (fighter)) rather than their makers names. As far as I know, in WW2 the Germans always referred to RAF fighters by their RAF names.
