Surrender Details: Surrendered from sea at Mar del Plata, Argentina on 17 August 1945. Moved to Buenos Aires in late August and handed over to the US Navy.
Time in US Navy: In company with U-530, and escorted by the fleet tug Cherokee (ATF-66), U-977 left the Rio Santiago Naval Base in Buenos Aires on 11 September 1945. The two U-Boats stopped at Rio de Janeiro in Brazil from 16 to 20 September and, after having to repair the engines of both U-Boats whilst at sea, they then stopped at Trinidad in the British West Indies from 2 to 5 October, where they were inspected by the Allied Tripartite Naval Board on 3 October. They left Trinidad on 5 October and arrived at the US Navy's Submarine Base at New London on 12 October 1945.
U-977 was allocated to the US Navy as a war prize, and in November and December 1945 it took part in a 5-week tour of seven US East Coast ports in company with the destroyer Baker (DE-190), starting in New London on 5 November. Baker and U-977 visited Albany (6 to 12 Nov), Poughkeepsie (12 to 15 November) and Newburgh (15 to 17 November) in New York State, Wilmington (18 to 22 November) and Lewes (22 to 25 November) in Delaware, Richmond (26 November to 2 December) in Virginia, and Washington, DC (3 to 10 December). After arriving back at New London on 13 December 1945, U-977 was declared out of service and to be retained for explosive tests.
Final Disposal: Sunk on 13 November 1946 by Atule (SS-403) off Cape Cod, Mass.
