What German Submarine Was Repaired In The Port Of San Juan At The Beginning Of Second World War?

ARA San Juan SSK - TR-1700

The wreckage of the Argentine navy submarine that exploded and disappeared one year ago was located in the Atlantic Ocean on 16 Nov 2022, said the navy, crushing the last hopes for relatives of the 44 crew. There has been "positive identification of the ARA San Juan," at a depth of 800 metres, a statement on Twitter from the navy said. The Seabed Constructor, a vessel owned by Usa search business firm Body of water Infinity, which set out in September 2022 on the latest attempt to find the San Juan, made the discovery.

The send "Seabed Constructor" arrived at Expanse i / Subarea 15a and fabricated the descent of the ROV (remotely operated vehicle) in order to investigate signal of interest No. 24 reported by Sea Infinity. As a result it was verified that it was the submarine ARA "San Juan" which is at a depth of approximately 900 meters, beingness its exact location very close to the hydroacoustic bibelot detected by the CTBTO (Organisation of the Comprehensive Nuclear-Examination-Ban Treaty) , near the concluding known position of the submarine.

The area where it was located had been raked past all the participating navies that intervened in the search tasks, but did non accept the technology used by the company Body of water Infinity. Although the visibility was reduced by virtue of the turbulence and salinity that exists in that depth, some constituent parts of the submarine could be identified so far.

A larger department, comprised of the pressure level hull, is in one piece at 907 meters. This pressure hull, of special steel of 33 millimeters of thickness, is the habitable sector where are the batteries and all the systems and equipment that the submarine has, and that owns a size of betwixt 25 to 30 meters of length past vii of width. Besides, other parts of the submarine of smaller dimensions and forms were identified, congruent with the bow department, the stern and the sail. To the East and Northeast of the expanse there is an important field of debris that was plant scattered on a surface of 80 ten 100 meters.

The hydroacoustic anomaly reported on November 23, 2022 by the Argentine Ambassador in Vienna (Republic of austria), where the Organisation for the Comprehensive Nuclear-Test-Ban Treaty (CTBTO) works, allowed the identification of an area with the eye 27 km away from the last known position of the ship. In this sector, located in front of Golfo San Jorge, is the continental slope that is made up of three terraces. The upper part is the narrowest, with a steep slope. The second is formed by a lighter gradient that is between 700 and 800 meters deep. This is where the submarine canyons and their tributaries (ramifications) begin to form. Finally, a stepped surface continues until reaching the lower gradient, which reaches 3,000 meters deep, leading to the continental emersion (also called abyssal plains).

According to the investigations carried out by the Training and Arming Control of the Argentine Navy (Search and Rescue Authority, SAR), together with the Naval Hydrography Service under the Ministry of Defense, an area was projected where the event would have occurred that produced the wreck of the submarine ARA "San Juan". At that place is the starting betoken (caput) of the canyon chosen "Almirante Brown".

The canyons tin exist graphed and understood as submarine rivers that in their head are between 60/70 meters deep and 800 meters wide. Its constitution dates back millions of years and is made up of sand, clay, silt and other agglomerates. In add-on, they have small coral formations that are constituted by the presence of natural gas deposits. According to the studies carried out on the seabed, at greater depth the speed of the currents decreases. Therefore, when something is deposited there, the aforementioned currents generate "sinkholes" around it. Thus, the object will non be eroded and then quickly and the aggregating of sediments will exist gradual.

The international search for the 44 crew of the missing ARA San Juan submarine was officially called off past the Argentine Navy, although the search for the vessel continued in shallow waters. The announcement was made 15 days after an explosion was believed to accept sent the sick-blighted vessel to the depths of the Atlantic ocean off the coast of Patagonia. More than 28 ships, nine planes and iv,000 people from 18 countries were involved in the search covering 557,000 nautical miles; more than, including radar monitoring.

Luis Taglapietra, whose son Dami�due north was a 27-yr-sometime trainee, told the TN news channel: "This is perverse and impossible to empathise. They�re playing word games. What they are actually saying is that they�re non going to be looking for it whatever more than." Speaking separately to the Guardian, Taglapietra, a lawyer who has been asked to correspond several of the coiffure�due south families, said: "They lied to u.s. from the get-go. We don�t know what happened and information technology�south impossible to tell the truth from fabrication."

"Argentina missing submarine" (El submarino desaparecido en Argentina). "Sous-marin argentin disparu" ((in French, "Argentine submarine disappeared") "Argentinisches Marine-U-Kick im Atlantik verschollen" (in High german, "Argentine naval submarine lost in the Atlantic").

Relatives of the 44 crew members on board a submarine were told 24 November 2022 they �are all dead� following reports of an explosion on the 24-hour interval it vanished. Argentine Navy officials phoned to tell them the sailors had been killed in a blast betwixt 600 and iii,000 feet underwater, co-ordinate to families. Officially, the authorities had not speculated on the status of the crew and vowed to proceed to search for the vessel.

An investigation by the Ministry building of Defense warned about "irregularities" in the direct purchase of the batteries of the ARA San Juan, , according to the copy of those actions that came secretly to three official offices, and which LA NACION agreed to . The information coincides with an inspect of the General Syndicature (Sigen), which too questioned the process.

The investigation, developed by defense experts between 2022 and 2022, determined that the Navy would have breached regulatory and operational standards for the repair of one-half-life and the replacement of batteries; that information technology was sought to straight the purchase of supplies to benefit certain suppliers, and that, in this process, they would accept acquired supplies with overdue guarantees and committed crimes.

"The information nerveless is conclusive at least to back up not only that these contracts did non accommodate to the regulated administrative procedure, but also that the military personnel in charge of them may accept engaged in unlawful conduct that benefited the awarded companies, Bell-ringer Gmbh and Ferrostaal AG ", said the defense force researchers.

According to La Naci�n newspaper published today , an investigation carried out past defense experts between 2022 and 2022 concluded that the Navy would have breached "normative and operational standards" to carry out the repair and replacement of submersible batteries, and that in that process "We sought to direct the buy of supplies to benefit certain suppliers" and "we would take acquired supplies with expired guarantees". The companies that would have benefited from the armed services personnel in charge of the authoritative procedure would be Bell-ringer Gmbh and Ferrostaal AG.

Luisa Rodr�guez, mother of non-deputed officeholder Ricardo Gabriel Alfaro, criticized the lack of investment in the Armed Forces. "The fault lies with the bad governments after the Malvinas, who did not requite the budget to recover the equipment," she said. "You tin not send people with something that is not in status to a place where you practice non know if they are going to come back," the woman added. Regarding the ARA San Juan, Rodriguez recalled that although it was repaired, information technology is far from being a modern vessel. "They said 'duck on the water' and a submarine can not be dislocated with a duck," said Andrea, Alfaro's wife, in reference to the judgement that Cristina Kirchner released when the send returned to activity afterward its half-life repair. "They are onetime, very onetime ships, and I tell President Macri to be aware of how this is," Rodr�guez insisted.

Assuming that the submarine remained intact after the blast and settled to the ocean flooring, the ship had only a seven-day supply of oxygen, which might accept run out Wednesday 22 Nov 2022. Obvously, the exact location of the submarine was un-knowable at that time, but the waters in the general vicinity of the last reported location of the gunkhole ranged from about 300 feet [several times less than the submarine's crush depth] to peradventure 3,000 feet [several times greater than the submarine'south trounce depth].

But furious relatives forced the navy to confirm there had been a massive explosion near to where the sub was in the hours before its last transmission on Wed, November 15. Itati Leguizamon, whose husband was one the coiffure members blasted the navy, calling them �perverse bastards�. She said: �According to them, they but found out about the explosion now, but who is and so stupid to believe that? They are a disgrace, they lied to united states of america.�

The U.S. Navy and an international nuclear exam ban monitoring organisation said the "hydroacoustic anomaly'' was produced just hours afterward the navy lost contact with the submarine. The Argentine navy described the explosion that followed near the sub'due south location as an "anomalous, short, violent." [there is evidently a disharmonize as to whether the explosion occured before or subsequently the final transmission from the boat]

The Argentine Navy confirmed 23 November 2022 that there was an explosion in the area where the lost submarine was terminal seen on Nov. 15, Clarin reported. Navy spokesman Enrique Balbi mentioned that this would explain why the crew didn't apply any of the emergency mechanisms. Balbi added that information suggested that the submarine could have experienced an implosion, explaining why they hadn't institute any pieces of the submarine in the body of water. They said a sound was detected four hours after the last contact was made with the submarine, which had an electric fault. The Argentine navy lost contact with the ARA San Juan submarine presently after the vessel'due south captain reported a failure in the battery organisation while the sub was submerged off Argentina's South Atlantic coast.

The search for the Argentine submarine "ARA San Juan" that lost contact with the base on Wednesday fifteen November 2022, continued for days without results. In a written message, Pope Francis, also an Argentinian, said that he prayed for the 44 sailors and assured the families of the crew members, the armed services and civilian authorities of "his closeness in these difficult times". Previously, Navy spokesman Balbi said one possibility was that the submarine couldn't become afloat and was stranded in the bottom of the sea, or that it could have been navigating on the surface.

The submarine had recently [in 2022] completed an extensive overhaul, offset in 2007, that had entailed extensive repairs, including cutting the boat in half to supercede the propulsion system. All this work was done by a workforce that had never worked on a submarine, or had not done such work in over 2 decades. President Fernandez de Kirchner historic the completion of the repairs in 2022, but in reality three more years were needed before the piece of work was washed. It might be speculated that the limited competence of the workforce, or political pressure from the President, could have introduced flaws in the gunkhole that created problems in 2022.

The first information indicated that a power failure had generated a burn in the battery bank of the transport, just this was denied by the Navy since no emergency warning was received earlier the communication was lost. "At the moment we have no news of communication liaison or visual or a fire in the battery area, if something important had happened, a special signal would have been issued and that did not happen," the Navy spokesperson added, denying the versions that circulated well-nigh what could happen to teh gunkhole.

The authorities launched a "search and rescue" state on Friday in accord with international maritime maritime conventions to intensify efforts to find the vessel. The "ARA San Juan", with 44 crew onboard, sailed from the port of Ushuaia and the Mar del Plata, 400 km south of Buenos Aires, when it lost contact on Wed.

"Nosotros believe that at that place has been a difficult communication problem, perchance because of power supply, and nosotros hope information technology is on the surface, but the detection is difficult," Navy spokesman Enrique Balbi said. All the ships in the zone were summoned to inform nigh whatsoever sighting or indicate of communication of the submarine, likewise every bit the bases of the declension. The head of the naval base of operations of Mar del Plata, Gabriel Gonzalez explained that " waves of 7 or viii meters and winds of 40 knots were recorded " that make the search hard and stressed that international aid continues to go far.

Argentine spokesman Enrique Balbi said on November 18, that the primary reason for the lack of contact with the submarine was considered to be "serious communication problems" that could exist associated with malfunctions in the power supply system. "We believe that it is on the surface," he added.

The crew of Argentina's lost ARA San Juan submarine endured an excruciating ii hours battling fires aboard the stricken vessel before it imploded at depth and sank, an official investigation revealed 06 April 2022. On xv November 2022, fire broke out in the battery tank located in the San Juan's bow. Water had entered through the sub'due south snorkel, triggering what was swiftly to become a fatal incident. Despite the influx of water, the vessel dove to a greater depth and attempted to continue the journey to its domicile naval base Mar del Plata, 400 kilometers due south of the majuscule Buenos Aires.

Investigators told the Nacion newspaper that the fires almost likely spread throughout the stricken submarine, forcing the crew to boxing the blaze in ferocious conditions. According to their report, the vessel eventually imploded � killing the 44 coiffure virtually instantly and sinking into the depths. The investigating commission was formed by Rear Admiral Adolfo Trama and Alejandro Kenny, along with Captain Jorge Bergallo, male parent of crew fellow member Jorge Ignacio Bergallo. The commission besides ruled out maintenance issues, rejecting claims the submarine was not seaworthy when it embarked on its ill-blighted final voyage.

Lawyers prosecuting the case of Argentina'due south missing ARA San Juan submarine, which disappeared from radars on xv Nov 2022 last year with all 44 crew on board, claimed 26 May 2022 that the vessel lacked sufficient food and oxygen supplies necessary to survive an emergency. Prosectur Valeria Carrera reached the conclusion based on a report presented in Congress past the current head of the Cabinet of Ministers, Marcos Pe�a.

The vessel needed to carry sufficient supplies to last 7 days for all 44 crew members, but the supplies on board were not enough for everyone, according to the report. The written report concluded that the submarine had "240 units of mixed preserves, emergency rations, in thermosealed flavors;" 240 half-liter bottles of Gatorade free energy beverage, and two cereal bars plus two chocolate bars for every crew member. Based on the documents submitted in the case, Carrera estimated that although the supplies covered seven days, they were adequate to feed "only 34 crew members � x less than the missing coiffure," said the lawyer.

Air and escape suits likewise failed to encounter the minimum requirements, Carrera connected. There were 600 fewer canister filters � used to avoid contamination by carbon dioxide � than the minimum recommended by the transport's manufacturer, and nigh had already expired. In add-on, "they also carried 24 OR 3000 oxygen devices (unremarkably chosen candelas), for the provision of six days of emergency oxygen, when the manufacturer of the submarine stipulates 100," said Carrera.

Months earlier the submarine's ill-blighted final voyage, San Juan Commander Pedro Martin Fernandez put in a serial of claims with the Argentine Navy, including for canned food and boned chicken. Commander Fernandez also raised the fact that coiffure members had to purchase drinks themselves to compensate for the brusk supply.

After having released moorings on 09 September 2022 from the port of Comodoro Rivadavia to requite continuity to the scientific search of the submarine ARA "San Juan", the send of the company Bounding main Infinity began operating in the expanse ane of exploration, where it arrived at fifteen:45, positioning itself at the southeast stop of it at Latitude 46� xiii.half dozen Southward, Longitude 59� 35.2 West.

The company estimated that in ten days information technology will sweep an area of 3200 km2 corresponding to the three areas defined by them based on the data received from the Argentine Navy and from other international sources that were consulted for the planning of the performance. Upon arriving at each of them, they will launch the five AUVs (Autonomous Underwater Vehicle) at bounding main with two hours difference between them (total ten hours), mapping the submarine bed with South / N full general direction for 42 consecutive hours. After the recovery of the same (10 hours), the information collected by the side scan sonar, multibeam probe and magnetometer (4 hours) will be downloaded, and finally processed (12 hours).

The AUV take an immersion chapters of 6000 mtrs. of depth. Two types of ROV (Remotely Operated Vehicles) equipped with high definition cameras will be used to identify the objects establish in the search. If the search in those three areas is unsuccessful, the visitor will expand to a circle of 25 nautical miles of radius centered on the concluding reported position of the submarine on November fifteen, 2022. By contract, the visitor Ocean Infinity does not have any geographical limitations for the search and take a minimum of lx operating days and a maximum of 120, and must make a photographic and audiovisual record in case of the discovery of the wreck.

Authorities accept opened a criminal investigation into the San Juan's disappearance. The approximate heading the case has so far heard testimony from 70 people but says she is no closer to knowing what happened.
