of Battery Barbour, and the 3-inch M1898 guns of Battery Bacon, all in 1920. These were not replaced. By 1924, Fort Wadsworth had become an infantry post, with the coast artillery batteries in caretaker status, with only a few soldiers garrisoned for maintenance. The construction of long-range 12-inch gun batteries at Fort Hancock, New Jersey and a 16-inch gun battery at Fort Tilden had relegated Fort Wadsworth to the second line of defense for Greater New York. World War II Although Fort Wadsworth was an important mobilization center, it received little new armament in World War II. New defenses for Greater New York in that war centered on Fort Tilden, the long-range 12-inch batteries at Fort Hancock, and a new 16-inch gun battery at the Highlands Military Reservation in Navesink, New Jersey. Fort Wadsworth's heavy guns were gradually scrapped during the war. Battery 218, a magazine bunker for a pair of 6-inch guns, was built but not armed. A 16-inch gun battery (Battery 115) was proposed for Fort Wadsworth but not built. Four 3-inch guns of Battery Turnbull were relocated to Battery New Turnbull, still at Fort Wadsworth.

Post World War II through 1990s Following World War II all US coast artillery guns were scrapped. From 1948 to 1952 Fort Wadsworth was the Headquarters of the 102nd Antiaircraft Artillery Brigade (New York National Guard) for the air defense of New York City. From 1952 until 1960 it was the Headquarters of the 52nd Antiaircraft Artillery Brigade, until the Brigade moved to the Highlands Air Force Station. Although Fort Wadsworth was a Nike missile headquarters 1952-1964, no missiles were stationed at the fort. However, a 120 mm M1 gun battery was at the fort 1952-55. It then was the site of the United States Army Chaplain school, while also hosting the Fort Wadsworth Museum within Fort Tompkins, which displayed free exhibits depicting the history of the fort and the U.S. Army. The base was turned over to the United States Navy in 1979, which used it as the headquarters of Naval Station New York. As a result of the Base Closure and Realignment Commission process, the Navy left and the
