A mere 10 days after World War II concluded in Europe, the Argentine Navy, coastal residents and local fishermen became aware of an approaching German U-Boat convoy. The FBI was overwhelmed with rumors and witness accounts and the NKGB (precursor to the KGB) issued directives to investigate and acquire any information concerning the activities of these submarines. To this day, no party has assumed responsibility, and the U-Boats, crews, passengers, and cargo have eluded discovery. The Argentine State makes no admission and holds a firm position regarding the clandestine arrival of U-boats in Argentina before, during, and after World War II, dismissing the possibility as "highly improbable".
However, in 2010, while returning to the port of Quequén in the coastal town of Necochea, commercial fisherman Captain Enrique Silva, nicknamed "Petete", spotted an uncharted underwater structure. Fast forward to early 2021, Petete agreed to guide team members Nicolas Lanzat and Mariano Di Franceschi to the wreck site, equipped with a basic side-scan sonar. On March 4, 2021, they managed to capture an elementary sonar image of the wreck and informed the Argentine Naval Prefecture. A preliminary examination of the sonar image suggests that the object is not a surface ship and could potentially be a scuttled German U-Boat. However, definitive confirmation requires a thorough on-site examination.
Building upon this extraordinary discovery, an upcoming expedition is planned with the primary objective of collecting and analyzing all remaining evidence to enable irrefutable identification of this wreck. The first survey, scheduled from (timing TBC), will employ a Klein 4K ultra high resolution side-scan and a Norbit 2048 beam multibeam sonar to conduct a comprehensive hydrographic survey of the area. The second survey (timing TBC) will deploy a Blue Robotics remotely operated vehicle (ROV) to generate a precision photogrammetric 3D model of the wreck and a team of professional technical divers to conduct a forensic examination.
An exhaustive exploration and identification of this wreck could rewrite the official historical account and raise intriguing and important questions about the presence of U-Boats along the Argentinian coast, the South Atlantic, and Antarctica.
“The Argentine government must do everything possible to achieve one thing regarding this shipwreck in Necochea: that the whole truth and nothing but the truth be known. Only by clarifying what happened in the dark stages of our past can we have a better future, having contributed to clearing the burdens weighing on the global public opinion regarding our nation and being able to achieve justice.”
