On display in East Willard Park, Washington Navy Yard, D.C., in October 1972. This gun is Number 111, built at the Washington Navy Yard in 1922 for planned installation on the abortive South Dakota (BB 49-54) class battleships and Lexington (CC 1-6) class battle cruisers. Note railway trucks supporting the gun barrel. The two sixteen-inch projectiles displayed alongside the gun are inert shells fired by USS New Jersey into San Clemente Island, California, during shore bombardment practice in 1968.
