German submarine U-2513 was a Type XXI U-boat of Nazi Germany's Kriegsmarine, that was operated by the United States Navy for several years after World War II.

Design

Like all

kilowatts; 3,900 shaft horsepower), two Siemens-Schuckert GU365/30 double-acting electric motors each providing 5,000 PS (3,700 kW; 4,900 shp), and two Siemens-Schuckert silent running GV232/28 electric motors each providing 226 PS (166 kW; 223 shp).[3]

The submarine had a maximum surface speed of 15.6 knots (28.9 km/h; 18.0 mph) and a submerged speed of 17.2 knots (31.9 km/h; 19.8 mph). When running on silent motors the boat could operate at a speed of 6.1 knots (11.3 km/h; 7.0 mph). When submerged, the boat could operate at 5 knots (9.3 km/h; 5.8 mph) for 340 nautical miles (630 km; 390 mi); when surfaced, she could travel 15,500 nautical miles (28,700 km; 17,800 mi) at 10 knots (19 km/h; 12 mph).

2 cm (0.79 in) C/30 anti-aircraft guns. She could carry twenty-three torpedoes or seventeen torpedoes and twelve mines. The complement was five officers and fifty-two men.[3]

Service history

Kriegsmarine

Her keel was

Blohm & Voss of Hamburg. She was commissioned on 12 October 1944 with Kapitänleutnant Hans Bungards in command. Bungards was relieved on 27 April 1945 by Fregattenkapitän Erich Topp
, who commanded the boat for less than two weeks.

U-2513 conducted no war patrols. On 9 May 1945, Topp surrendered his command at Horten Naval Base, Norway. U-2513 was taken to Oslo on 18 May, then to Lishally, Northern Ireland, which she reached on 9 June. In August 1945, the U-boat was transferred to the United States.

United States Navy

A year later, August 1946, U-2513 began an extensive overhaul in

Key West, Florida. The following day, she began six months of duty which included both evaluation tests of the U-boat's design and duty in conjunction with the development of submarine and antisubmarine tactics. The Greater Underwater Propulsion Power Program
(GUPPY) would be initiated because of the results of these tests.

On 21 November 1946 President Harry S. Truman became the second American President (after Theodore Roosevelt[4]) to travel on a submarine when he visited U-2513. The sub went 440 feet (130 m) below the surface with the President on board, and a demonstration was made to him of the German schnorchel (a specialized submarine snorkel).[5]

On 15 March 1947, U-2513 headed north from

Key West, Florida, bound for the New England coast, and arrived at Portsmouth, New Hampshire, on 22 March. She remained there until 8 September when she began six weeks of operations from Portsmouth and New London, Connecticut
, under the auspices of the Commander, Submarines, Atlantic Fleet. She concluded that duty on 15 October and departed New London to return to Key West. U-2513 resumed her old duties at Key West five days later and continued them until the summer of 1949.

In mid-June 1949, the submarine moved from Key West north via

on 7 October 1951.

The final resting place of U-2513 is about 23 nautical miles (43 km; 26 mi) northwest of the

Dry Tortugas, 70 nautical miles (130 km; 81 mi) west of Key West) in about 213 feet (65 m) of water at 24°52.015′N 83°18.594′W / 24.866917°N 83.309900°W / 24.866917; -83.309900.[6]
She is reachable only by divers experienced in decompression diving at that depth. The site is rarely dived on due to its depth and remote location.
