    Pentagon Is Reviewing Deal to Equip Australia With Nuclear Submarines

    by

    The 2021 pact, meant to help counter China’s ambitions in the Asia Pacific, will be examined to ensure that it meets “America First criteria,” a U.S. official said.The Trump administration is reviewing whether a security pact between the United States, Britain and Australia meant to equip Australia with nuclear submarines is “aligned with the president’s America First agenda,” a U.S. defense official said on Wednesday.When the deal was reached under President Joseph R. Biden Jr.’s administration in 2021, it was billed as crucial for countering China’s growing military influence in the Asia Pacific. Now, its review appears to reinforce President Trump’s skeptical and transactional approach to longstanding alliances, including demands that allies spend more on their own defense.The Pentagon official said the review would ensure that the pact, known as Aukus, met “common-sense, America First criteria,” including ensuring that U.S. forces are at “the highest readiness,” that allies are doing their part, and that “the defense industrial base is meeting our needs.” The review was first reported by The Financial Times.Australia’s defense minister, Richard Marles, said both Australia and Britain had been notified about the review and that all three nations were still committed to the deal.“We’ve been aware of this for some time. We welcome it,” Mr. Marles said in a radio interview with ABC Melbourne on Thursday, Australia time. “It’s something which is perfectly natural for an incoming administration to do.”Australia sees the Aukus agreement as central to its defense strategy in the coming decades in a region increasingly shaped by China’s assertive military posturing. Nuclear submarines can travel much farther without detection than conventional ones can and would enable the Australian Navy to greatly extend its reach.Under the pact, Australia is scheduled to receive secondhand Virginia-class nuclear submarines from the United States in the 2030s while scaling up the capacity to build its own, using a British design. But there has been concern in both Washington and Canberra about whether the United States can build new submarines to replenish its fleet quickly enough for the older ones to be transferred to Australia.Elbridge Colby, the U.S. under secretary of defense for policy, said during his Senate confirmation hearing in March that he was skeptical about the pragmatic feasibility of the deal. The Financial Times reported that Mr. Colby was heading up the Pentagon review.“So if we can produce the attack submarines in sufficient number and sufficient speed, then great,” Mr. Colby said at the hearing. “But if we can’t, that becomes a very difficult problem.”Even before the review was announced, concern and anxiety had been building in Australia over whether it could continue to depend on its longstanding relationship with the United States, given the Trump administration’s treatment of allies.Mr. Marles, the Australian defense minister, said in the radio interview that he was confident the Aukus deal would proceed because “it’s in the interests of the United States to continue to work with Australia.”Michael D.

      This Elusive Antarctic Squid Was Seen for the First Time

      by

      An expedition in the Southern Ocean captured video of a rare species of deep-sea cephalopod. Until now, it had been found only in fishing nets and in the bellies of seabirds.The deep-sea environs of the Earth’s poles are home to mysterious ocean creatures: giant sea spiders, Antarctic sea pigs, phantom jellyfish. Finding and identifying these animals can be difficult, however; some are known only because researchers found their remains in fishing nets or in the bellies of seabirds. But on Christmas Day last year, the crew of the R/V Falkor (Too), the Schmidt Ocean Institute’s research vessel, caught sight of a creature never before seen alive.The team had planned to deploy its remotely operated vehicle, SuBastian, in a site known as the Powell Basin, but the movement of ice blocks forced the group to explore the region’s outer edges instead.When the submersible dropped 7,000 feet, the team unexpectedly spotted a shadow through the live feed, which turned out to be an Antarctic gonate squid, a rare species of cephalopod, three feet long and releasing a green cloud of ink.“It was a beautiful squid,” said Andrew Thurber, a deep-sea researcher at the University of California, Santa Barbara, who was aboard the vessel. “You see beauty all the time in the deep ocean, and this was just one classic example of it.”No Antarctic gonate squid had ever been seen alive before, as far as the team was aware. They followed it for a couple of minutes and made sure to record it on video, capturing the creature’s red coloration and white spots.“Videos like this get me really excited,” said Linsey Sala, a museum scientist who manages the pelagic invertebrate collection at Scripps Institution of Oceanography and was not involved in the expedition. Discoveries of species like this “can be really informative to how they live life at great depths,” Ms. Sala said. Unidentified specimens might be sitting in collections around the world, she added, in which case the video footage could be helpful in revealing what they are.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      North Korea Says It’s Building a Nuclear-Powered Submarine

      by

      The announcement came amid fears that Pyongyang may be receiving crucial military technology from Russia in return for sending troops and weapons for its war against Ukraine.North Korea said on Saturday that it was building its first nuclear-powered submarine to enhance its nuclear weapons abilities, and the state news media showed the nation’s leader, Kim Jong-un, inspecting part of what appeared to be a new submarine larger than any owned by the country.The announcement, made in the state news media, came as United States and South Korean officials feared that the North may be receiving technological help from Russia to help modernize its military in return for sending troops and conventional weapons to help in its war against Ukraine.Mr. Kim “learned about the building of a nuclear-powered strategic guided missile submarine,” the North’s official Korean Central News Agency said in a report on Saturday about his visit to an unidentified naval shipyard. The agency carried photographs showing what appeared to be the hull of a submarine under construction.It was the first time that North Korea claimed that a nuclear-powered submarine was under construction and claimed to show a photograph of it.North Korea has dozens of old Soviet-era submarines, all diesel-powered, which would have to resurface frequently to recharge their batteries during a long-distance trip like crossing the Pacific. A nuclear-powered submarine, which can cover a long distance without resurfacing, would enhance North Korea’s ability to approach a faraway enemy like the United States without being detected, and to strike it with nuclear missiles.The state news media on Saturday quoted Mr. Kim as saying that his country’s naval might would be “fully displayed in any necessary waters without limitation.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Family of Titan Crew Member Sues OceanGate

      by

      Paul-Henri Nargeolet, a French explorer, died along with four other crew members when OceanGate’s Titan craft imploded on its journey to the Titanic.The family of a French explorer who was aboard the Titan submersible, the vessel that imploded last year during its failed mission to explore the Titanic wreckage, killing all five people aboard, has filed a wrongful-death lawsuit against the craft’s manufacturer, OceanGate Expeditions.Paul-Henri Nargeolet, a French explorer whose deep knowledge of the sunken ship earned him the nickname “Mr. Titanic,” was hired to assist OceanGate, a Washington State-based ocean exploration company, during the Titan’s journey to the Titanic.But the company and its founder, Richard Stockton Rush III, who also died aboard the vessel, misled Mr. Nargeolet about how the submersible was built, according to the lawsuit filed in King County, Wash.“Mr. Rush confessed to a ‘mission specialist’ on one Titanic voyage that he had ‘gotten the carbon fiber used to make the Titan at a big discount from Boeing because it was past its shelf life for use in airplanes,’” according to the lawsuit, which the Houston-based law firms Buzbee Law Firm and Schecter, Shaffer & Harris said was filed on Tuesday.The French deep sea explorer and Titanic expert Paul-Henri Nargeolet with a miniature version of the sunken ship.Joel Saget/Agence France-Presse — Getty ImagesThe lawsuit also accuses Mr. Rush of negligence for a variety of reasons, including falsely advertising a “crackling noise” that was said to be an advanced “safety” feature to alert crew members when to abort a mission. In reality, the lawsuit says that sound “is nothing more than the detection of a possibly imminent failure of the carbon fiber hull.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Billionaire Plans Dive to the Titanic in a Newly Designed Submersible

      by

      Larry Connor, 74, who made his wealth in real estate, said he’s building a new acrylic-hulled submersible that will be certified and rigorously tested to show that deep sea exploration is safe.A real estate billionaire in Ohio is planning an underwater voyage to the site of the Titanic shipwreck, where a submersible imploded on its approach to the sea floor a year ago, killing all five passengers on board.Shortly after the OceanGate disaster, Larry Connor, 74, a real estate investor and amateur adventurer, contacted the co-founder of Triton Submarines, Patrick Lahey, imploring him to build a submarine that could reach the depths of the Titanic safely and repeatedly, according to The Wall Street Journal.The two men aim to explore and conduct scientific research at the site, located off the coast of Newfoundland, 12,500 feet under the sea, in a two-person submersible that Triton is designing in the summer of 2026.“Ours is just not a trip to the Titanic,” Mr. Connor said in an interview on Tuesday. “It’s a research mission.”“The other purpose is to demonstrate to people around the globe that you can build a revolutionary, first-of-its-kind sub and dive it safely and successfully to great depths,” he added.The custom sub, which Mr. Connor plans to call “The Explorer — Return to the Titanic,” is still in the design phase and will be based on an existing submarine design that Mr. Lahey had worked on for years. It is listed on the Triton website as the Abyssal Explorer, an acrylic-hulled vessel than can reach depths of 13,000 feet, “the perfect submersible for repeated trips to the deep ocean.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
