In 2011, researchers off the coast of Brazil discover the remains of the U-513.

History of the wreck
The German submarine U-513 was launched on 29.10.1941 at the Deutsche Werft, Hamburg, and was commissioned on 10.01.1942. The Type IX C submarine had 2 diesel and 2 electric engines in its hull (76.7 x 6.76 x 4.70 m). The diesel engines produced 4400 hp with a maximum speed of 18.2 knots while the electric motors with 1000 hp were allowed to reach only 7.7 kn.

.

First, it was assigned as a training submarine under the 4th U-flotilla where it also made its 1st enemy voyage from August 1942 to October 1942, sinking 2 ships and damaging one. The 2nd enemy voyage was fruitless, while on the 3rd enemy voyage, still under Rolf Rüggeberg as commander, it again sank 2 ships and damaged one. For the 4th enemy expedition, Kapitänleutnant Friedrich Guggenberger took over command of the U-513. In the South Atlantic, he and his crew sank 4 ships and damaged another. Kapitänleutnant Friedrich Guggenberger was an experienced commander and had already been able to sink the British aircraft carrier Ark Royal with the U-81.

Now, when he reported to the BdU off the Brazilian coast during the 4th Enemy Flight, his report was too detailed. Long radio communications enabled him to be located by radio direction finding. The U.S. Navy squadron ordered Mariner VP-74 under Lt. Whitcomb to the supposed location, where he located the submarine and attacked it with depth charges. Although the U-513 replied with anti-aircraft fire, it could not prevent the submarine from sinking. of the 53-man crew, 20 men managed to leave the submarine afloat. Unfortunately, by the time the USS Barnegat arrived, 13 more comrades had drowned in the 5 hours. Among the 7 survivors was Kapitänleutnant Friedrich Guggenberger.

Until the end of the war, the remaining crew members spent time in a prisoner-of-war camp in Arizona.
Guggenberger returned to Germany and initially worked as an architect until he made it to the Admiral of the Navy when the Bundeswehr was formed in 1956. In 1988, Rear Admiral Guggenberger disappeared while walking in the woods. His body was not rediscovered until 5 years later.

Diving into the wreck
The wreck of the U-513 was discovered 120 km east of the Brazilian city of Florianopolis. Researchers from the University of Vale do Itajaí had been searching for the submarine for 2 years. Since the U-513 is located at a depth of 75 meters, it is accessible to tec divers. However, whether it will be cleared for diving will have to be decided by the Brazilian government. Last but not least, the U-513 is a war grave. And your calm should be kept.
