An A-5 (Werknummer 550 002, bearing Stammkennzeichen of KM+TB) – documented use was as testbed for FuG 200 Hohentwiel ASV maritime patrol radar with flexible MG 131Z nose gun installation. It is speculated to have been intended for the installation of an enlarged bomb bay to be used in the Junkers Ju 287. It is also speculated that the V38 was the prototype for a German "atomic bomber" (purportedly capable of carrying a fission device as a droppable weapon). Remains found at Prague's Rusiye field on V-E Day.
