USS Georgetown (AGTR-2/AG-165), was an Oxford-class technical research ship acquired by the U.S. Navy to provide a seaborne platform for global eavesdropping on behalf of the National Security Agency.

Georgetown was a converted "Liberty-type" cargo ship, was laid down as SS Robert W. Hart under a Maritime Commission contract on 4 May 1945 by New England Shipbuilding Corporation, South Portland, Maine; launched 10 July 1945; sponsored by Mrs. Fred W. Woolsey; and delivered under General Agency Agreement from War Shipping Administration (WSA) to Atlantic, Gulf & West Indies Lines, New York, 2 August 1945.

Robert W. Hart sailed in merchant navy service until entering the National Defense Reserve Fleet, Wilmington, North Carolina, in December 1946.

Between 20 July and 13 October she again operated off the eastern coast of South America; and, after returning to Norfolk, she received new electronics equipment, including a Communication Moon Relay System that allowed her to instantly transmit her findings to NSA headquarters in Fort Meade, Maryland.

Besides gathering communications intelligence, she rescued two boatloads of Cuban refugees, transited the Panama Canal four times, passed through the eye of a hurricane, and won the Battle Efficiency "E." She was sold to the Dutch firm of N. V. Intershitra for $185,001 on 24 July 1970 and scrapped about a year later.
