The Nazi U-boat that sailed into legend after the war ended

In short: When Germany surrendered in May 1945, the crew of the U-530 did not stop. Instead, they embarked on a mysterious voyage to Argentina, sparking decades of conspiracy theories involving Nazi gold, secret Antarctic bases, and even the survival of Adolf Hitler.

The U-530, a Type IXC/40 German submarine, completed seven war patrols before its final, enigmatic journey. Under the command of Oberleutnant zur See Otto Wermuth, the vessel surfaced near Puerto Rico in May 1945, roughly 1,000 miles east-northeast of the island. Despite orders to surrender at the nearest United Nations port, Wermuth—fearing an enemy trick—steered the submarine toward South America, eventually surrendering to the Argentine Navy in Mar del Plata on 10 July 1945.

The crew's arrival in Argentina fueled a whirlwind of apocryphal stories. Rumors suggested the submarine had transported escaping Nazi leaders, such as Adolf Hitler, or vast quantities of Nazi gold. Some even alleged the vessel had visited Antarctica. While an Argentine reporter once cited a police report claiming Hitler and Eva Braun had landed off the coast, the Argentine Ministry of the Navy officially denied that any high-ranking Wehrmacht officials or high-profile Nazis were aboard.

The submarine's true history was marked by documented combat and technical specifics. During its service, U-530 sank the Swedish freighter Milos in March 1943 and the American tanker Sunoil in April 1943, totaling 12,063 gross register tons (GRT) in sunk tonnage. The vessel was equipped with specialized radar technology, including the FuMO 61 Hohentwiel transmitter. After its surrender, the crew and the boat were transferred to the United States, where the U-530 was eventually destroyed as a target by a torpedo from the USS Toro on 28 November 1947.
