In April 1961 flying was halted and the unit reassigned to McGuire Air Force Base in New Jersey. With the reassignment of the 514th, Mitchel AFB was subsequently closed on 25 June 1961. The property was turned over to Nassau County.
The former base is home to Hofstra University, Nassau Community College, and Nassau Veterans Memorial Coliseum. The main runway, however, can still be seen in the northeast and southwest corner of this image.
