16" guns were also transported to the US Army Aberdeen Proving Ground on the shores of upper Chesapeake Bay in Maryland, where they were quite often fired for years (even now?) for very high altitude, high trajectory testing. They could have been originally delivered by rail (PRR or B&O), or by water (the waters around the grounds are very, very shallow, however). I never figured out whether these guns were surplused from coastal defense duties, or were from Naval sources.
