Chinese submarine crews are training to operate farther into the Western Pacific. AdvertisementChina is forcing its submarine crews to endure more intensive and realistic training exercises. Ironically, while rigorous training is intended to create a more skilled and aggressive submarine force, these changes could backfire. "What the literature does suggest is that the PLAN submarine force is simultaneously incorporating a wide range of new operational guidance, platforms, and technologies that are pushing the crews and equipment of the PLAN submarine force in ways they have not been stressed before." "But it still must improve further to be capable of supporting what is expected of the submarine force."

Named, JS Raigei (“Thunder Whale” in Japanese), the diesel-electric attack sub is the fourth boat of the Taigei-class , which translates to “big whale.”Its launch comes almost exactly one year after the launch of the third Taigei-class sub, JS Jingei (or “Swift Whale”). With a building time of about two years each, Japan has launched a new Taigei-class sub every year since 2020. China’s current sub fleet, numbering some 59 boats, includes approximately 10 improved Kilo-class , 12 Type 039-class , and 21 Type 039A-class diesel-electric attack subs. Japan is building a larger submarine fleet but it is still only about a third the size of China's. AdvertisementJapan has so far launched four Taigei-class submarines since 2018; JS Taigei, JS Hakugei, JS Jingei, and JS Raigei.

CNN —Former President Donald Trump allegedly discussed potentially sensitive information about US nuclear submarines with a member of his Mar-a-Lago resort in Palm Beach, Florida, following his presidency, ABC reported Thursday. The member is Australian billionaire Anthony Pratt, sources told ABC. He added that he heard Pratt sharing potentially sensitive information minutes after his meeting with the former president, sources told ABC. But Pratt told investigators that he was not shown any government documents, the sources said. Similarly, we share weapons technology.”However, even if submariners in Australia knew the information Trump relayed to Pratt, if the information was classified, then it was illegal to share publicly.

A riddle haunts the Titan disaster. It’s the presence on the doomed craft of Paul-Henri Nargeolet, 77. The Frenchman was one of the world’s great submariners. So why was he, of all people, diving repeatedly to the Titanic on a submersible that many experts saw as a catastrophe waiting to happen? “It’s a source of great puzzlement,” said Victor L. Vescovo, a sea explorer who hired Mr. Nargeolet to oversee a series of unusually deep dives.

☆ Secretive and highly paid submariners are behind some of Russia's most worrying undersea operations

Known as GUGI, the directorate is responsible for conducting sabotage and surveillance against critical maritime infrastructure, including undersea cables and energy pipelines. NATO's intelligence chief warned this year that Russia could attempt to sabotage undersea cables in retaliation for Western support of Ukraine. Yantar, the special-purpose survey ship, was spotted lingering near undersea cables west of Ireland in 2021. "We know that Russia has the capacity to map but also potentially to conduct actions against critical infrastructure," NATO Secretary General Jens Stoltenberg told reporters on June 16. "That's also the reason why we have, for many years, addressed the vulnerability of critical undersea infrastructure."

☆ Stalled Sister City Plan Reveals New German Wariness of China

City officials in the northern German port of Kiel were flattered this year when the Chinese port of Qingdao — about 40 times its size — proposed partnering up as a sister city. The two cities had a history of cooperation dating to when the Germans helped their Chinese counterparts develop a sailing venue for the 2008 Olympics in Beijing. Almost too good, in fact, for security experts, who noted other, less innocent similarities. Kiel, home to about 250,000, hosts much of Germany’s Baltic naval fleet, Germany’s equivalent of the Navy SEALs, military research facilities and big shipbuilders making, among other things, six brand-new, state-of-the-art submarines. Qingdao, a city of more than nine million, is home to China’s North Sea fleet, a marine research academy and China’s main submariners school, which specializes in submarine hunting.

☆ Here's why Rolex watches are so expensive and how the brand gained its luxury status
▼ + stars: | 2023-04-29 | by ( Dominick Reuter | ) www.businessinsider.com time to read: +6 min

With their precision manufacturing, specially sourced materials, and exceptional craftsmanship, Rolex watches have never come cheap, but neither were they out of financial reach for 1960s working professionals in search of perfect timekeeping and technical innovation. "Back then, anybody could afford a Rolex," Hess told Insider. Dealers would buy luxury watches in Switzerland to carry across the border and sell in Italy. That reputation has helped Rolex crush the competition with a quarter of the luxury watch market — more than double that of runner-up Omega. "They all buy the little wannabe Rolex brands in the beginning and finally, when they achieve success, they buy that Rolex."

☆ Why is the US sending a nuclear submarine to South Korea?
▼ + stars: | 2023-04-27 | by ( Brad Lendon | ) edition.cnn.com time to read: +6 min

Seoul, South Korea CNN —When the presidents of the United States and South Korea this week announced a landmark deal to deter North Korean aggression, one element of the pact stood out. Here’s what you need to know about the submarine and why it’s heading to South Korea. The Nuclear Threat Initiative at the James Martin Center for Nonproliferation Studies estimates that each Trident missile can carry four nuclear warheads, meaning each US ballistic missile submarine could be carrying about 80 nuclear warheads. One arriving in South Korea on a port visit – which must be arranged 24 to 48 hours in advance – would be far more visible, giving North Korea an advantage, Schuster said. Kim’s threats have prompted some in South Korea to call for Seoul to become a nuclear-armed power itself.

The assessment of China's military said China's fleet of six Jin-class ballistic missile submarines were operating "near-continuous" patrols from Hainan Island into the South China Sea. Equipped with a new, longer-range ballistic missile, they can hit the continental United States, analysts say. Communications are crucial and complex for ballistic missile subs, which must remain hidden as part of their mission. The Chinese military has emphasised that the Central Military Commission, headed by President Xi Jinping, is the only nuclear command authority. Russia is thought to keep most of its 11 ballistic missile submarines largely in bastions off its Arctic coasts, while U.S., French and British boats roam more widely, three analysts said.

☆ The loser of a rare submarine vs. submarine battle was found 80 years after being sunk

In July 1941, a British submarine sank an Italian submarine in the Mediterranean Sea. It was against this backdrop that the Royal Navy submarine HMS Torbay and the Italian submarine Jantina squared off in the Aegean Sea near the island of Mykonos. The first two passed in front of the Italian sub, but the next struck it and exploded. The Italian sub sank quickly, and only six of the 48-man crew survived, swimming to a nearby island. By the end of the war, Torbay had sunk more than 40 German, Italian, and Japanese warships, merchant ships, and other vessels.

KCNA via REUTERSSEOUL, March 13 (Reuters) - Nuclear-armed North Korea test-fired two strategic cruise missiles from a submarine on Sunday, state news agency KCNA said on Monday just as U.S.-South Korea military drills were due to begin. DPRK stands for North Korea, officially the Democratic People's Republic of Korea. North Korea has a large submarine fleet but the 8.24 Yongung (August 24th Hero) is its only known experimental ballistic missile submarine. North Korea has said it is building an operational ballistic missile submarine.
