Dahlgren might be a better bet. They still had the 18" gun there when I was there (about 30 years ago now but ...) as well as a 16" that was still fired occasionally (although they didn't fire shells very often dropping a 16" round in some ladies front yard in Colonial Beach was a bit of an embarassment).
Are the carrier fly-boy types still called air-dales too? When ships had big guns, the gunners were called cannon cockers, but now with the missiles being the deck weapon of choice, what are the missile shooters guys called?
