First World War submarine lost with 35 British and Allied crew on board is finally found – ending 103-year mystery

First World War submarine lost with 35 British and Allied crew on board is finally found - ending 103-year mysteryThe wreck of the first allied vessel lost in the First World War has been discovered 103 years after it vanished off the coast of Papua New Guinea following a search that has finally ended Australia’s oldest naval mystery. HMAS AE1, Australia’s first submarine, which had 35 British, Australian and New Zealand crew members aboard, disappeared near the Duke of York Islands during a patrol for German warships on September 14, 1914.  The submarine, which had only been in service for seven months, was captained by Lieutenant Commander Thomas Besant, a 30-year-old British officer who had been seconded from the Royal Navy. Despite at least twelve search operations over the decades, no trace of the vessel was found. But the wreck was finally found more than 1,000 feet underwater after an underwater survey captured an image of the vessel during a search involving the government and private backers.  Following the survey, searchers aboard the Furgro Equato dropped an underwater camera to the seabed to confirm that the vessel was AE1. The team of maritime surveyors, marine archaeologists and naval historians scoured the search area with a multi-beam echo sounder and side-scan technology in an underwater drone Credit:  REUTERS "Australia's oldest naval mystery has been solved," said Marise Payne, Australia’s defence minister. “The boat and her crew, who've been on eternal patrol since 1914 … have now been found. I truly trust that this discovery will bring peace of mind to the descendants of the families of the crew who lost their lives.” The cause of the sinking has not been confirmed but it is believed to be related to a technical failure during a practice dive. Peter Briggs, a retired rear admiral who led the search, said the loss was probably  due to a sudden “diving accident”, noting that the fin guardrails were stowed and the upper conning tower hatch appeared to be shut. He told The Australian newspaper that the submarine appeared to suffer a “high energy event” – possibly due to an explosion involving one of its torpedoes or a high pressure air cylinder – which may have occurred after it began to sink but caused it to quickly flood and accelerate towards the seabed. The search led by Find AE1 Limited, and was funded by the Royal Australian Navy and the Silentworld Foundation, with assistance from the Submarine Institute of Australia Credit:  REUTERS “When the end came for the men of AE1 it would have been very fast, they may well have not known what hit them,” said rear admiral Briggs, president of the Submarine Institute of Australia. “The submarine appears to have struck the bottom with sufficient force to dislodge the fin from its footing, forcing it to hinge forward on its leading edge, impacting the casing.” The location of the wreck has been kept secret to prevent salvage attempts. Timeline | Submarine accidents Following the discovery, the crew aboard the search vessel held a memorial for the dead officers and sailors. Australian and Papua New Guinean officials will consider ways to preserve the site and establish a lasting memorial. Rear Admiral Briggs said the discovery “opens the next chapter: learning exactly what happened to it”. “It will be quite a detective puzzle,” he added.

Argentina sacks navy chief over submarine tragedy

Argentina sacks navy chief over submarine tragedyArgentina dismissed its naval chief on Saturday, the most high-profile officer to be fired a month after a submarine went missing with 44 crew members on board. "The defense minister asked him to retire. It's a political decision," a navy officer told AFP on condition of anonymity about the decision to remove Admiral Marcelo Srur during an ongoing investigation into the sub's disappearance. Srur is the fifth senior officer to have been relieved of his functions so far over the ARA San Juan's disappearance. Military sources say President Mauricio Macri is willing to retire most of the naval leadership. The government is also creating an internal investigative commission that will be headed by retired captain Jorge Bergallo, father of the ARA San Juan's second commander, Jorge Ignacio Bergallo, government sources told state news agency Telam. Friends and family of missing submarine crew members place a flag on the fence of the naval base in Mar de Plata, Argentina An international search operation has so far failed to locate the vessel. The 43 men and one woman who were aboard are believed to have died in the tragedy. But families of the missing have pressed the government to continue the search, which has not yet been officially closed. Some relatives claim the navy has been hiding information, and have called for a parliamentary investigation. On Friday, they protested in Mar del Plata, where the submarine was based, and Buenos Aires. Relatives have focused their anger on the condition of the three-decade-old sub, which had undergone a seven-year refit to extend its service, and the navy's guardedness since the start of the search operation. The navy has a poor reputation in Argentina. During the 1976-1983 military dictatorship, some navy units served as detention and torture centers, and an estimated 30,000 people disappeared.

America's P-8 Poseidon Submarine Killer: The Plane North Korea, Russia and China Hate

America's P-8 Poseidon Submarine Killer: The Plane North Korea, Russia and China HateAs trans-Pacific relations assume new prominence in the twenty-first century, the P-8 will remain one of a number of means by which the United States and other operators assert their presence over international waters. In the event of conflict, they would also serve a vital role hunting down marauding submarines and tracking the movements of surface adversaries. There is a decent chance you have already flown on one of the U.S. Navy’s key new aircraft—or rather, the 737 airliner it is based on.

Last memo from missing Argentine submarine reveals start of a battery fire

Last memo from missing Argentine submarine reveals start of a battery fireThe last communication from the missing Argentine submarine ARA San Juan revealed a leak of sea water had caused a short circuit and “the beginnings of a fire” in the batteries, according to a copy of the message published by Argentine television. “Entry of sea water through the ventilation system into battery tank No. 3 caused a short circuit and the beginnings of a fire in the battery room. Bow batteries out of service. At the moment in immersion propelling with split circuit. No updates on personnel, will keep informed,” the document obtained by the channel A24 said. The message was purportedly sent by the commander of the ARA San Juan by radio and received as a transcription. A24 did not say how it had obtained the document, on which the Argentine Navy has not commented. The communication appears to contradict some of the information released by the Navy. It was sent at 8.52am on the morning of the sub’s disappearance on Wednesday, November 15, while the authorities have said the vessel’s last message was received at 7.30am.  Search and rescue mission for Argentinian submarine It also goes into greater detail regarding the faults allegedly suffered by the ARA San Juan. The Navy waited five days to confirm rumours the submarine had suffered a battery fault, and then insisted it was unrelated to the disappearance.  On Monday, before the leaked document was broadcast, Captain Enrique Balbi, the Navy spokesperson, told a press briefing that the sub had reported “the entry of water through the snorkel, a short circuit and the beginnings of a fire, which for us is smoke without flames. It was corrected, they isolated the battery and navigated with another circuit, it was being propelled with the circuit of the stern”. Timeline | Submarine accidents Almost two weeks after it disappeared, the only trace of the sub and its 44 crew members has been the reports of an apparent explosion close to its last known location at approximately 11am that morning.  The message is also likely to raise further questions over the Navy’s decision to wait two days to begin a physical search for the ARA San Juan. While the force has insisted this was in accordance with protocol for a submarine that had lost communication, the existence of such faults has generated doubts over that decision.

Pressure grows on Argentina's navy over missing submarine, as hopes fade for its crew of 44

Pressure grows on Argentina's navy over missing submarine, as hopes fade for its crew of 44Argentina’s Navy faces multiple investigations over the disappearance of the submarine ARA San Juan and the possible dismissal of its entire top brass, amid a swelling controversy over the accident and search efforts. A day after the Navy confirmed an apparent explosion close to the submarine’s last known position, the internal war that has been raging between the force and the government in Buenos Aires spilled out across Argentine media. Oscar Aguad, the defence minister, incensed by a succession of alleged failings by the force – which left him to learn of the ARA San Juan's disappearance from the media and then delayed revealing it had suffered a battery fault – is reported to have opened more than 40 probes to determine responsibility. Any dismissals would be unlikely to happen until the sub is found. The newspaper Clarin cited “high level” officials as saying that President Mauricio Macri wanted all efforts to remain focused on the search, though changes were “surely” ahead. On Friday, amid the growing furore, Mr Macri publicly cautioned against "taking risks in assigning blame". "This is going to take a serious, deep investigation that yields certainties about why what we are seeing happened," he told a news conference. Timeline | Submarine accidents Despite a fleet of US underwater vehicles scouring the area of the explosion, Captain Enrique Balbi, the Navy spokesperson, yesterday said they still had no trace of the ARA San Juan. There was some confusion over the scale of the explosion, as the head of the Vienna-based Comprehensive Nuclear Test Ban Treaty Organisation – one of the sources of Thursday's report – suggested it could have been "very small” and may not have destroyed the San Juan. But Captain Balbi said the report Argentina had received “did not say a small explosion”. Amid angry complaints from families that Navy officials had “lied” to them and withheld information, Captain Balbi acknowledged that mistakes may have been made. “We are not infallible,” he said. “If there were errors, the Navy will not hesitate to say sorry.” But he defended the force against claims of delays in the operation, insisting protocol had been followed in waiting two days to begin a physical search. He also insisted the submarine had been in good condition. Relatives have raised doubts about the seaworthiness of the ARA San Juan, built in 1985. On Thursday, Itati Leguizmon, wife of radarist Germán Oscar Suárez, said that the submarine had suffered a “serious fault” in 2014 – the year that its mid-life renovation was completed. Ms Leguizmon, a lawyer, claimed an incident had occurred in which the submarine found itself unable to surface: the situation was so grave that the crew “said goodbye to each other”. Family members finally abandoned a vigil by the Mar del Plata naval base on Friday Credit:  Esteban Felix/ AP Questions are now being asked about that 2014 renovation, in particular, the decision to replace all internal elements of the batteries but retain the old casings. But, naval sources told La Nacion, the process was supervised by the submarine’s German builder, Thyssen Nordseewerke, and checked by Argentina’s National Institute of Industrial Technology, and was deemed satisfactory. Previous claims by the then-president, Cristina Fernandez de Kirchner, that the repaired vessel could go to sea for another 30 years is also coming under scrutiny. As the government itself faces increasing pressure, party politics is likely to enter the blame game. The head of the congressional defence committee – a former defence minister under both Kirchner presidencies – will reportedly request an appearance by Mr Aguad.  Submarine rescue mission Federico Pinedo, the Senate’s provisional president, admitted publicly that Mr Macri was “angry at the situation”, but cautioned against premature conclusions over the tragedy. “It could have been an accident or it could have been have been because of lack of maintenance," he told the channel Todo Noticias. "There has to be a serious investigation.” But he could not resist a shot at the Kirchner governments, which he categorized as “anti-military”. “The neglect of defence hardware was a terrifying thing,” Mr Pinedo said. Families of the 44 crew members of the submarine on Friday gave up hope and went home after a days-long wait at the Mar del Plata naval base, saddened and angered. Jésica Gopar, wife of Mendoza Fernando Santilli, who was aboard the sub, told local reporters: "My husband missed my son's first birthday."
