As just one example, the German Heinkel He 177A heavy bomber had such a remotely operated twin-MG 131 machine gun Fernbedienbare Drehlafette FDL 131Z (Z - "zwilling"/twin) powered forward dorsal gun turret, with the full translation of the German term comprising the prefix as "Remotely controlled rotating gun mount". The term "lafette" in German actually refers to a gun carriage of nearly any type, with its original use as being for the mounting design for bombard-style siege guns of the Middle Ages.
