the transportation school wound down, Fort Slocum took on a mission of rehabilitating soldiers who had been court-martialed in Europe and sent home. Late 1940s Following World War II, Fort Slocum was briefly considered as a nuclear research center; what became Brookhaven National Laboratory was chosen instead. From 1946 to 1949, Fort Slocum housed Headquarters First Air Force. It was renamed Slocum Air Force Base in June 1949; this only lasted for a year before being turned back into an Army post in June 1950. From 1955 to 1960, Fort Slocum housed part of Nike Ajax air-defense missile battery NY-15. The missiles were stored on launch rails and in underground bunkers on nearby Hart Island, with the radar and control base situated on Davids' Island. In July 1960, after only five years of operation, Nike Battery NY-15 was closed. 1950-1965 From 1951 to 1962, Fort Slocum was the home of the U.S. Army Chaplain School. From 1951 to 1954, Fort Slocum was home to the joint services Armed Forces Information School. From 1954, this was truncated to the Army Information School; from 1964, this was again reorganized into the joint services Defense Information School, which was later transferred to Fort Benjamin Harrison, Indiana, and then to its current home at Fort Meade, Maryland. Over the course of this time, troops from the various services, officers and enlisted, male and female, American and allied, were trained in applied journalism, oral communication, radio/TV broadcasting, public and world affairs, and photography. In 1965, the information school was moved to Fort Benjamin Harrison, Indiana when Fort Slocum was deactivated. After closure Fort Slocum was deactivated on November 30, 1965. During the decades that followed, the facilities of the former Army post were neglected and deteriorated severely and continued to occupy Davids Island into the beginning of the 21st century. The ruins were among the factors complicating redevelopment of the island. Beginning in 2004, however, Congress appropriated funds to remove the ruins through a Defense Department program that assists communities in reusing former defense facilities. During the summer of 2008, the city of New Rochelle demolished all remaining structures on the island, including the iconic water tower on the northern end of the island, with plans to turn the island into a park.
