The fort was decommissioned after WW2 and the property was sold to the town and to private owners beginning in about 1947. The fire control tower indicated on the map was used as part of the Army/Lincoln Labs Nike program-related radar research and development during the late 1940s and early 1950s and at one point had a large radar antenna on its roof. A Nike target tracking radar was also erected on Bayley's Hill (the eastern edge of the fort) during the 1950s.
