When did naval terminology shift from batteries to weapon systems?
Short answerThe transition became common as ships mixed guns, missiles, torpedoes, and ASW launchers, especially from the 1970s into the 1980s, though individual missile and Hedgehog groups could still be called batteries.
NotesA gun-centered ship naturally described its armament as batteries, and early missile ships could extend the same term to groups of launchers. The language of weapon systems became more useful once guns, missiles, torpedoes, and ASW launchers had to be discussed as a combined combat suite. The approximate period given for the shift in everyday usage is the 1970s and 1980s, later than the first guided missiles. Older technical usage persisted, as multiple Hedgehog launchers could formally constitute a battery even when sailors simply called them launchers.
