Shahed-136 prototype was created in 1980s Germany, and it was called DAR

"DAR (Die Drohne Antiradar)." -- as if that would make any sense...

Obviously not, because it's name was: _D_rohne-_A_nti-_R_adar_ (Drohne-Anti-Radar / like: drone, anti radar -- typical German military buerocratic phrasing)

German abbreviations are as sensible as in other languages. "Die" is just the feminine article to "Drohne" (Die Drohne).
