German submarine U-530 was a Type IXC/40 U-boat of the German Navy during World War II. She was laid down at the Deutsche Werft in Hamburg on 8 December 1941 as 'werk' 345, launched on 28 July 1942 and commissioned on 14 October 1942 with Kapitänleutnant Kurt Lange in command. He was replaced in January 1945 by Oberleutnant Otto Wermuth.

She served with the 4th U-boat Flotilla while training, then the 10th flotilla from 1 March 1943 to 30 September 1944 and the 33rd flotilla from 1 October 1944 to 8 May 1945. U-530 completed seven war patrols, sinking two ships totalling 12,063 gross register tons (GRT) and damaging another of 10,195 GRT. She surrendered in Mar del Plata, Argentina on 10 July 1945.

Wartime service[]

1st patrol[]

The submarine left Kiel on her first patrol on 20 February 1943. Her route to the Atlantic took her through the gap between Iceland and the Faeroe Islands. On 9 March she sank the Swedish ship Milos in mid-Atlantic, at a point roughly equidistant from the southern tip of Greenland, Iceland and northwest Scotland. She also sank the American Sunoil on 5 April after the tanker had already been hit by U-563. She then made her way to the port of Lorient in occupied France, arriving on 22 April.

2nd, 3rd and 4th patrols[]

These three forays were relatively uneventful, apart from her home port being moved to Bordeaux and then La Pallice.

5th patrol[]

Her fifth patrol took her to the Caribbean Sea where she attacked and damaged the American Chapultepec on 26 December 1943. She was forced to return to France when she was rammed by the tanker Esso Buffalo on 29 December. She arrived at Lorient on 22 February 1944.

6th patrol[]

For her sixth sortie, U-530 departed Lorient on 22 May 1944 ultimately for operations in the Trinidad area. On her outward voyage she was to rendezvous with the Japanese submarine I-52 and supply the larger boat with a Naxos radar detector, a radar operator and a German navigator to help the I-52 complete her journey.

The two submarines rendezvoused on 23 June in mid-Atlantic, 850 mi (1,370 km) west of the Cape Verde Islands. The Allies had been informed of the rendezvous and directed the escort carrier Bogue (CVE-9) to the scene; her aircraft managed to sink the I-52 with an acoustic torpedo.[2] U-530 returned to base, this time Flensburg, after 133 days at sea.

A short journey from Kiel to Horten in southern Norway was her recorded next move, but it did not count as a patrol.

7th patrol and surrender[]

U-530 did not initially surrender at war's end, as ordered by Admiral Dönitz; instead the crew headed for Argentina and ultimately surrendered to the Argentine Navy on 10 July 1945 at Mar del Plata.

Her captain, Oberleutnant Otto Wermuth, had decided to surrender at Mar del Plata. He did not explain why it had taken him more than two months to reach there, nor why the submarine had jettisoned its deck gun, or why the crew carried no identification, nor what had happened to the ship's log.

The unexpected arrival of U-530 started many rumors. Brazilian Admiral Jorge Dodsworth Martins said he believed that U-530 could have sunk the cruiser Bahia, while Admiral Dudal Teixeira, also a Brazilian, believed that the U-530 had come from Japan. An Argentine reporter claimed that he had seen a Buenos Aires provincial police report to the effect that a strange submarine had surfaced off the lower Argentine coast and had landed a high-ranking officer and a civilian who might have been Adolf Hitler and Eva Braun in disguise.[3] U-977 was also accused of sinking the Bahia; an inquiry eventually found that she had been sunk due to a gunnery accident.[4]

The Argentine Naval Ministry issued an official communique in which they stated that U-530 was not responsible for the sinking of the Bahia; no Nazi leader or high-ranking military officers were aboard; and the U-530 had landed no one on the coast of Argentina before surrendering.[3]

The crew of the U-530 were interned, they and the boat were then transferred to the United States. The submarine was sunk as a target on 28 November 1947 by a torpedo from American submarine Toro (SS-422).

Sensors[]

Radar[]

U-530 was one of the few U-boats that was fitted with a FuMO 61 Hohentwiel U Radar Transmitter. It was installed on the starboard side of the conning tower.

Radar Detection[]

U-530 was fitted with the FuMB-26 Tunis antenna.
