    The Navy's new stealth submarines might not be so stealthy after all. A top executive at the company building the subs has thrown doubt on whether cutting-edge pump-jet propulsion technology will be used as planned. The ultra-quiet technology was a key selling point for the French design that won the Government's competitive evaluation process to build the new submarines at a cost of $50 billion. Jean-Michel Billig, Executive Director of Naval Group, was asked at a naval conference in Sydney earlier this month whether pump-jet propulsion "remained viable" for the Australian submarine. He said it "could" be viable, but also...

    An Akula-class Russian submarine of the Northern Fleet on the surface. Russian MoD. In late 1984, when the first Akula submarine of the Soviet Navy put to sea, it immediately changed the way anti-submarine warfare would be conducted. With the Akula’s arrival the American submarine fleet would no longer enjoy the dramatic undersea advantages they had possessed since the end of the World War II. The Akula, which is Russian for shark, stunned NATO with its high-level of stealth, especially compared to any Soviet submarine before it. That’s because in the battle for undersea supremacy, silence is the key to...

    A new report says that Israel asked Germany to extend the length of the submarines it planned on purchasing, spooking the Germans, who surmised that Israel wanted the submarines retrofitted to be compatible with nuclear missiles. The report, which was the result of an investigation between Ronan Bergman from Yediot Aharonot and the German Die Zeit newspaper, said that German Chancellor Angela Merkel opposed the request and even demanded the opinion of the German intelligence services, which eventually approved the request. Israel was not aware of the behind the scenes drama. Bergman wrote that the change to make the submarines...

    Here’s a thought experiment: what if, suddenly, all the world’s submarines could no longer submerge? There they would be, on the surface of the ocean, slow, unwieldy, with no effective protection against attack. They’d be sitting ducks. Fanciful? Perhaps not. With a high probability, something very like this awaits the world’s submarines within the next couple of decades. Submarines are classic stealth predators. They have only one big trick — their invisibility — and they rely on it utterly to mount a successful attack. In that respect, they are no different from sabre-tooth tigers or trapdoor spiders. And like such...

    Australia would have no way of stopping an intrusion by a major power if the government did not invest in modified off-the-shelf submarines, a defence expert warned as debate over the nation’s submarine capability reignites. An independent report released yesterday into the $50 billion future submarine project — Defence’s largest acquisition — called for the urgent purchase of six new off-the-shelf submarines on top of the 12 Shortfin Barra­cudas selected by the Turnbull government last year. The report from consulting firm Insight Economics, Australia’s Future Submarine: Getting This Key Capability Right, drew a fierce rebuke from Defence Minister Marise Payne...

The new submarine is stated to be 69th conventional and nuclear submarines, according to unofficial estimates by global defence think-tanks. A new nuclear submarine has been turned over to the People's Liberation Army Navy (PLAN), state-run Global Times today quoted an official with the China Shipbuilding Industry Corporation or CSIC as saying. However, experts believe that this submarine is not the most advanced Type 096, which is China's next...

    The South Korean Navy's submarine SSK Lee Eok Gi (SS-071) wobbled a bit, setting sail from the country's newest naval port on Jeju Island. The slight odor of oil that filled the cramped, windowless diesel-electric sub made some of the strangers aboard worry about getting seasick. "This is (like) a lake," Cdr. Kang Byung-oh, the captain of the 1,200-ton sub, told a small group of reporters in the torpedo room, which doubles as a briefing room, last week. "The waves are only about 1.5 meters high. When we came here yesterday from Jinhae (in South Gyeongang Province), they were 5...

    It’s something of an open secret that maritime special operations forces around the world rely on a wide array of highly specialized water craft, such as high-speed, low-profile speed boats, miniature submarines, and more. Now, one company, SubSea, is trying to combine a number of these features into single design it calls the Diver Delivery Unit (DDU), which can transform from a speedboat to a mini sub and back again. The DDU concept is centered on a symmetrical twin-hull design, both of which could carry personnel or other equipment. The United Kingdom-based firm says the final arrangement will be both...

    Poland is interested in buying French weaponry, especially missile-equipped submarines, officials said after talks between the two countries’ defence ministers. “We want to conclude this contract as soon as possible, preferably still this year," Poland’s Defence Minister Antoni Macierewicz said, referring to a possible submarine deal. He was speaking after talks with France’s Armed Forces Minister Florence Parly in Paris on Wednesday,. “The strength of the French offer” is that the submarines would come together with cruise missiles as part of a single deal, Macierewicz told Poland’s PAP news agency. But “there are still details that need to be worked...

    Copenhagen (AFP) - A Danish submarine inventor being held over the grisly death of Swedish journalist Kim Wall is to appear in a Copenhagen court on Tuesday, where the suspicions against him could be ramped up to murder. Peter Madsen is expected to appear in person at the court hearing due to begin at 2:00 pm (1200 GMT), the Danish public prosecutor's office told AFP. The 46-year-old inventor has been been in custody since August 12 suspected of "negligent manslaughter" in a gruesome case that has puzzled investigators and shocked the public.

    ngineers working with the Royal Navy have let their imaginations run wild designing what submarines of the future could look like and have come up with stunning concepts which mimic nature. Vessels shaped like manta rays, eel-like drones and swarms of fish-shaped torpedoes are just some of the ideas proposed for revolutionising underwater warfare. Eel-like drones could be deployed from the submarines “With more than 70pc of the planet's surface covered by water, the oceans remain one of the world's great mysteries and untapped resources,” said Commander Peter Pipkin, the Royal Navy's fleet robotics officer. "It's predicted that in 50...

    Researchers say they’ve solved one of the most enduring mysteries of the American Civil War: what caused the puzzling demise of the H.L. Hunley, the first combat submarine in history to sink an enemy warship. The Confederate craft famously disappeared with all its crew on 17 February 1864, just after destroying the USS Housatonic in Charleston Harbour. The Hunley’s wreck was not found until 1995. When it was raised from the seabed in 2000, the skeletons of its eight-man crew were still at their stations, with no evidence of escape attempts.

    The first combat submarine to sink an enemy ship also instantly killed its own eight-man crew with the powerful explosive torpedo it carried, new research has found. The HL Hunley fought for the confederacy in the US civil war and was sunk near North Charleston, South Carolina, in 1864. Speculation about the crew's deaths has included suffocation and drowning, but a new study claims that a shockwave created by their own weapon was to blame.

    When the UC3 Nautilus sailed from the Port of Copenhagen on the evening of Aug. 10, the homemade submarine bore just two people: its famed Danish inventor and the Swedish journalist reporting on his invention. Less than a day later, only one of them was still alive. Peter Madsen's submarine sank midday Aug. 11; he was rescued by a private boat, but journalist Kim Wall was nowhere to be found. It was Wall's boyfriend who reported her missing, and authorities wasted no time in arresting the 46-year-old Madsen after he came ashore, charging him that same day with manslaughter and...

    Project 677 Lada-class diesel-electric attack submarines will lack air-independent propulsion systems (AIP) for the foreseeable future, the head of Russian-state owned Admiralty Shipyards, Alexander Buzakov, revealed in a recent interview with Russian media this month. Buzakov confirmed that the third and fourth boat of the class will operate without AIP. AIP vastly improves the underwater endurance of a submarine by allowing it to operate its propulsion system without access to atmospheric oxygen. Given that there is less need for AIP subs to surface or use a snorkel to charge their batteries, the stealth capability of any boat fitted with this...
