    Default Xijinping got too many new models very advanced Terrex pics

    In this 2017 international military competition many Chinese combat vehicles beat even Russians, among 27 competitors including India. Russian admitted that many Chinese military toys are already top quality and performance, beats even USA. China is also unmatched as the global Drone Kingdom. Already beginning that Chinese and Russian tanks & armored combat vehicles are fitted with own build in semi-automatic drones. So they are very aware of full surrounding situation from a very far and safe distance.

    After 100 years of bullying and having vast tracts of its land robbed by foreign powers, the Chinese are paranoid about territorial integrity. The Chinese were never expansionist, per se. The humiliations are etched deep in Chinese memory, something a non-Chinese can never understand.

    Don't blindly swallow every word the western media utters; they're using divide-and-rule tactics by portraying the spectre of a belligerent, militaristic and expansionist China à la Japan and Germany prior to WWII.

    All the money thrown by China on high-tech weapons and modernizing the military is aimed at guarding its borders (Sino-Indian, Sino-Russian), protecting its South China Sea territory and the eventuality of reclaiming Taiwan.

    Default Xijinping overturned the Naval Advantage against all nations

    Now Xijinping built world's most quiet stealth submarines, plus the most sensitive sub detection system that is more than 1000X better than any sonar system - which is Chinese magnetic sensors.

    New PLA submarines have no propeller nor drive shaft and it is a quiet water jet pump driven by nuclear reactor and electricity.

    This Could 'Sink' the U.S. Navy: Lethal Stealth Submarines
    Harry J. Kazianis

    There is no force patrolling the world’s oceans more powerful than the mighty U.S. Navy. Washington’s nuclear-powered attack and ballistic submarines, aircraft carriers and surface combatants, all guided by the best trained sailors and professionals in the world, are no match when stacked up on paper one-on-one against the likes of Russia, China, Iran or any other challenger. And as history shows, going to war against Washington in a fair-fight is suicide. However, thanks to advances in modern, ultra-quiet conventional diesel-electric submarines, Washington will need to adjust its tactics if it were to tangle with any nation sporting these increasingly sophisticated weapons of war.

    To be fair, the threat of super-stealthy diesel submarines being deployed around the world has been present for decades. Still, newer boats are coming armed with advanced anti-ship weapons and are being combined with new air-independent propulsion systems (AIP) making them near impossible to find in the ocean's depths—a one-two punch that can’t be ignored.

    Recent history shows only too clearly the challenge the United States and other modern navies are facing from these heavily armed, ‘stealth’ submarines. Back as far as 2005, the U.S. Navy recognized the challenge and reached out to friends and allies for help. It was that year that the HMS Gotland, a modern AIP submarine serving in the Swedish Navy, made its home in California for a year. The goal was to test the impact of such a boat against U.S. aircraft carrier battle groups and other important vessels. It seems the boats, much cheaper to produce than the standard American nuclear-attack subs, created quite the stir:

    “Apparently the Navy got more than they were bargaining for when it came to finding and engaging the stealthy little sub. The Gotland virtually ‘sunk’ many U.S. nuclear fast attack subs, destroyers, frigates, cruisers and even made it into the 'red zone' beyond the last ring of anti-submarine defenses within a carrier strike group. Although it was rumored she got many simulated shots off on various U.S. super-carriers, one large-scale training exercise in particular with the then brand new USS Ronald Reagan ended with the little sub making multiple attack runs on the super-carrier, before slithering away without ever being detected. . . ”

    “. . .the little Swedish sub was "so silent it literally did not exist to our sensors."

    Thankfully the above were controlled exercises, crafted for America’s ‘silent service’ and surface combatant operators to understand the threat they were dealing with. However, not all encounters with ultra-quiet diesel boats have been as friendly—or just a mere exercise. Back in 2006, a Chinese Song-class attack submarine, created at least partially by Russian and Western technology and likely not nearly as advanced as the Gutland (the Song-class does not have AIP technology, for example) tailed the Japan-based U.S. Navy aircraft carrier USS Kitty Hawk in the East China Sea near Okinawa without being identified. While such a shadowing operation is quite normal, the sub “surfaced within five miles of the carrier, in deep waters off Okinawa, and only then was it spotted, by one of the carrier's planes on a routine surveillance flight.” Such submarines are armed with advanced anti-ship missile and wake-homing torpedoes.

    Moving to the present, Russia seems to be doubling down on its development of these important vessels. Moscow is developing an even deadlier class of boats:

    “The stealth capabilities of Russia’s new Lada-class diesel-electric submarines far exceed those of their predecessors, Admiraty Shipyard’s CEO Alexander Buzakov told the Russian press.

    “According to Buzakov, the new vessels are even stealthier than Russian Kilo-class submarines, thought to be one of the quietest diesel-electric submarine classes in the world and dubbed "black holes" for their ability to "disappear” from sonars.

    “The new submarines are able to maintain such a low profile thanks to a clever implementation of a next-generation anti-reflective acoustic coating and a new improved hydro-acoustic system, Buzakov said.

    He also added that during the new submarines’ construction and design process, the development team managed to gather a lot of valuable data which, among other things, allowed them to significantly improve the Kilo-class submarines as well.

    “The Lada-class submarines are designed to defend coastlines against ships and other submarines, gather intelligence, provide surveillance and reconnaissance missions, and act as a mother ship for special forces. With its new air-independent propulsion plant, a Lada submarine can remain submerged for as many as 25 days. With its vast array of weapon systems, the Lada is also world’s first non-nuclear submarine to be equipped with specialized launchers for cruise missiles.”

    So, with all this being said, what should the U.S. Navy do about this challenge? A greater investment in anti-submarine warfare would be a great place to start. New detection methods could also help, although such methods could also be used against Washington’s subs. Here’s an idea: maybe America should get in on the act and get some of its own? Hmmm. . .

    China is building submarines that could soon be quieter than US ones

    The US Navy’s Pacific fleet used to mock Chinese submarines for being too noisy and too easy to detect, but that has largely been remedied in recent years and China is now on the cusp of taking the lead in a cutting-edge propulsion technology.

    Naval experts said the new technology would help China build more elusive submarines, but might also prompt the United States to ramp up anti-submarine warfare measures.

    In a recent interview with China Central Television, Rear Admiral Ma Weiming, a leading Chinese naval engineer, showed a component of a new Integrated Electrical Propulsion System (IEPS) for naval warships in a laboratory. He said the system, which turns all the engine’s output into electricity, and a rim-driven pump-jet had been fitted to the People’s Liberation Army Navy’s newest nuclear submarines.

    “This is one of our work team’s first world-leading projects, which has been used on [China’s] next-generation nuclear submarines,” Ma said in May. “[Our technology] is now way ahead of the United States, which has also been developing similar technology.”

    Ma’s exalted status in the PLA Navy was highlighted by a photograph of then navy commander Admiral Wu Shengli holding an umbrella for Ma during an inspection of the PLA Naval University of Engineering in Wuhan, where Ma works, on a rainy day in June last year. The photo, posted on the social media website of the PLA’s Navy Magazine, sparked public curiosity about why the commander would give such “preferential treatment” to a rear admiral.

    Ma told CCTV “the ultimate goal” of developing the new propulsion system “was aimed at solving the problem of deploying high-energy radio-frequency (HERF) weapons on board”, hinting that China was close to emulating the US in that regard.

    HERF, a form of directed-energy weapon, can fire highly focused energy at a target, damaging it accurately and quickly. Directed-energy weapons require vast amount of electricity – something IEPS can deliver – and can counter the threats posed by fast missiles such as ballistic missiles, hypersonic cruise missiles and hypersonic glide vehicles. Besides China, the US, Russia and India are also developing them.

    The CCTV report did not say which types of Chinese submarines would use the pump-jet propulsion system, but mainland military websites said they believed Ma had hinted at the new-generation, nuclear-powered Type 095 attack submarines and Type 096 ballistic missile submarines.

    Collin Koh Swee Lean, a submarine expert from the S. Rajaratnam School of International Studies at Singapore’s Nanyang Technological University, said Ma’s remark showcased the growing scientific and technological maturity of China’s submarine development.

    “In the long term, if the pump-jet propulsion is declared fully operational and tested successfully ... future [Chinese] submarines would be equipped with pump-jet propulsion as a standard design feature,” he said, adding that the new technology would also benefit other naval shipbuilding projects, such as surface warships.

    “The operational/strategic ramifications would be that China would muster stealthier submarines ... and this essentially broadens various options for Beijing where it comes to the peacetime use of its naval capabilities.”

    A rim-driven pump-jet has a ring-shaped electrical motor inside the pump-jet shroud, which turns the vane rotor inside the pump-jet cavity to create thrust. The design reduces noise by removing the shaft and also creates fewer water bubbles, making it even quieter.

    Modern American and British submarines already use pump-jet propulsion, but Koh said the technology had not been adopted more widely because its design was complex, and just a few countries could support the technology with “a good deal of funding and technical expertise”.

    Beijing-based naval expert Li Jie said China had put a lot of resources and encouragement into developing cutting-edge technologies, including the pump-jet, air-independent propulsion (AIP) for non-nuclear submarines and other measures as part of its efforts to make Chinese submarines stealthier.

    “Both the ultra-quiet engine and AIP will help Chinese subs to elude foes as high concealment is very important to all nuclear attack subs,” Li said. “Quieter subs means stronger stealth capability, which will help them to conduct surprise attacks when necessary.”

    China has built Asia’s largest submarine base at Yulin, on the south coast of Hainan, near Sanya. The base features underground submarine facilities with tunnel access, shielding Chinese submarines that enter the South China Sea from the prying eyes of US reconnaissance satellites. That’s prompted American warships and aircraft to conduct more close surveillance operations in the disputed waters, which are claimed wholly or in part by mainland China, Vietnam, the Philippines, Malaysia, Brunei and Taiwan.

    Koh warned it was foreseeable that the US Navy would ramp up anti-submarine warfare measures to detect, classify and track Chinese submarines if they were harder to detect after being fitted with pump-jet propulsion and other stealth equipment.

    Chinese Nuclear SubmarineA Chinese Navy submarine takes part in an international fleet review to celebrate the 60th anniversary of the founding of the People's Liberation Army Navy in Qingdao, Shandong province April 23, 2009POOL New/REUTERS

    “This more intensified cat-and-mouse game would also result in the risk of underwater accidents ... between submarines or with surface ships,” he said. “The quieter the submarine is, the greater the likelihood of such navigational safety hazards and, potentially, they could cause diplomatic incidents in the context of those maritime disputes and of course, the persistent Sino-US divergence in views over foreign military activities in coastal states’ exclusive economic zones. ”

    The Chinese navy is likely to begin construction of the Type 096 submarines, which will be armed with 24 JL-3 intercontinental submarine-launched ballistic missiles, in the early 2020s, according to the Pentagon’s annual report to the US Congress this year.

    Ma, 57, became a household name in 2011 when he announced during a speech to accept a national technology award that his team had successfully developed a Chinese electromagnetic aircraft launch system (EMALS).

    Ma, a PLA deputy to the National People’s Congress, has since been asked by the media at the annual sessions of the national legislature when his EMALS will be fitted to China’s next-generation aircraft carriers.

    “I am very unhappy because I have no power to decide when my EMALS will be used,” a frank Ma told reporters on the sidelines of this year’s NPC session in Beijing in March. “But I dare to tell you that the EMALS developed by my working team is more advanced and reliable than the US system to be used on their Ford-class aircraft carrier.”

    The first of America’s Ford-class carriers, the first US vessel to use EMALS, completed sea trials in May.

    Sources close to the navy told the South China Morning Post earlier this year that Ma’s EMALS might be fitted on China’s third-generation nuclear-powered aircraft carrier, the Type 003. However, the Central Military Commission, chaired by Xi, has not decided when the Type 003 will be built, and construction work has not yet started on the second-generation Type 002.

    The PLA Navy has two aircraft carriers, the Liaoning, a refitted Soviet carrier commissioned in 2012, and the domestically built Type 001A, which was launched on April 26. They are both conventionally powered platforms featuring ski-jump take-off ramps.

    Xi has urged the PLA to pursue a “strong army dream”, but when asked by the Post whether he hoped to see his EMALS fitted to a Chinese aircraft carrier one day, Ma said he “never has any dreams” and was focused on finding practical projects for his team that would release its potential.

    “Whether the new technologies will be used never bothers me, because I’ve found that my task is to cultivate talent, meaning I have to create more opportunities for them and help them solve problems,” Ma said. “For example, compared with the US, China couldn’t devote as much funding to developing the electromagnetic aircraft launch system and advanced arresting gear (AAG) system, but I understood that our valuable resource was that I could mobilise my hundreds of talented students.”

    China's new submarine engine is poised to revolutionize underwater warfare


    It looks a lot like 'Red October' in real life.
    By Jeffrey Lin and P.W. Singer posted Jun 2nd, 2017 at 10:51am
    Red October Submarine

    Red October SSBN

    The Red October, a fictionalized version of the Akula (NATO reporting name Typhoon) submarine, has two pumpjets built into its rear for silent propulsion (though implausibly stated to use a noisy magnetohydrodynamic drive in the movie). According to Chinese state media, the nation's new nuclear submarines will soon use a similarly silent, cutting-edge pumpjet.

    Paramount Pictures

    In Tom Clancy's book (and, later, the 1990 film) The Hunt For Red October, a Soviet submarine debuts a revolutionary, ultra-quiet engine that uses pumpjets and electrical propulsion technology to elude its foes. Chinese state media has reported that the nation is fitting its newest nuclear sub with an engine that sounds a lot like Clancy's imaginings in the real world.
    Rear Admiral Ma Weiming China electric propulsion pumpjet

    The Admiral and the Pumpjet

    During his interview on state television, Admiral Ma Weiming, developer of the rim-driven pumpjet, shows off a laboratory, with a schematic of the pumpjet visible in the background, at right.

    CCTV 13

    This month, Chinese state TV channel CCTV 13 broadcast an interview with a top Chinese naval engineer, Rear Admiral Ma Weiming. The admiral is notably responsible for the development of multiple Chinese naval electromagnetic programs, including the electromagnetic catapult and railguns. In the interview, he stated that the PLAN is fitting its newest nuclear attack submarines with a "shaftless" rim-driven pumpjet, a revolutionary and silent propulsion system.
    China Type 095 SSN nuclear submarine

    Type 095 SSN

    The Type 095 SSN, seen in this speculative fanmade CGI, will likely have VLS cells for launching a wide range of cruise missiles, pumpjet propulsion, and improved quieting technology. (This earlier CGI shows the Type 095 with a more conventional pumpjet, though.)

    Medico-MAX

    If the system is being put on the latest vessels, it is likely to be used on the first Type 095 nuclear attack submarine (SSN), which is under construction.
    Rim Driven Thruster Pumpjet

    Rim Driven Thruster

    Shown here is a Schottel built rim-driven thruster, used to propel surface ships like yachts with minimal noise (the Chinese miltary rim-driven pumpjet would look similar but much larger).

    Schottel

    A rim-driven pumpjet has a ring-shaped electrical motor inside the pumpjet shroud, which turns the vane rotor (a vane rotor has the fan blades attached to a rotating band built on a cylinder interior, as opposed to a propeller shaft) inside the pumpjet cavity to create thrust. Previous submarine pumpjets are "shrouded propellers," which consist of a tubular nozzle covering the propeller. By removing the shaft of the propeller, the reduction in the number of moving parts decreases the noise made by the pumpjet, as well as saving hull space. Civilian manufacturers also claim that rim driven pumpjets are easier to maintain, and have less cavitation (bubbles that form during propeller movement), making them even more quiet.
    Rear Admiral Ma Weiming China electric propulsion

    IEPS

    Rear Admiral Ma presents a component of the new Chinese IEPS for naval warships; the Chinese variant is the world's first IEPS to run on a medium-voltage, direct-current system.

    CCTV 13

    Also in the video background was a large piece of electrical machinery, which is part of the PLAN's Integrated Electrical Propulsion System (IEPS). IEPS turns all the output of the ship's engine into electricity, unlike traditional propulsion designs, which convert engine and reactor output into mechanical action to turn the propeller shaft.

    The high electrical output can be used to power motors for the propellers or potentially high-energy weapons. Additionally, IEPS has far fewer moving parts, making them quieter, and thus ideal for use on submarines. When coupled with quieter reactors like the Type 095's reported natural circulation reactor, the rim-driven pumpjet and IEPS can drastically reduce the acoustic signature of any SSN.

    This combination, if it works, would be a significant gain for China's naval power. As China has gained in surface fleet numbers, stealthy planes, and longer-ranged missiles able to target U.S. carriers and air bases, America's submarine force has become viewed as its key advantage in any comparison. In turn, Chinese nuclear submarines have lagged behind competitors in their noisiness. Said another way, these innovations have the potential to strengthen a historic weakness.

    The reporting is significant for two more reasons. First, it illustrates the new openness in Chinese state media to discuss the technology behind previously secretive nuclear submarines, suggesting a greater confidence in showing off new military technology in order to impress domestic and foreign audiences.

    Secondly, if the system works, the Chinese may have stolen a march on the Americans and British, whose Columbia and Dreadnought nuclear ballistic missile submarine (SSBN) have the option for rim-drive pumpjets, but will not enter service until 2030. While the system would be on China's attack submarine, Chinese SSBNs could also use the rim-drive pumpjet to enhance their stealth and survivability—and, by extension, the credibility of China's second strike nuclear capability. These new submarine propulsion systems may not just power China's submarines of the future, but give Beijing a true superpower's underwater armada.

    This means US navy's strategic Ohio class Trident nuke subs for final nuclear counter strike can be found and eliminated during the 1st strike, hence no more counter-strike deterrence any more.

    China’s quantum submarine detector could seal South China Sea


    Submarine
    Tailed by a SQUID

    Snaprender/Alamy Stock Photo

    By David Hambling

    On 21 June, the Chinese Academy of Sciences hailed a breakthrough – a major upgrade to a kind of quantum device that measures magnetic fields. The announcement vanished after a journalist pointed out the invention’s potential military implications: it could help China lock down the South China Sea.

    “I was surprised by the removal,” says Stephen Chen of the South China Morning Post, who raised the issue. “I have been covering Chinese science for many years, and it is rare.”

    Magnetometers have been used to detect submarines since the second world war. They are able to do this because they can measure an anomaly in Earth’s magnetic field – like one caused by a massive hunk of metal.

    But today’s devices can only detect a submarine at fairly short range, so tend to be used to home in on the location once the sub has already been spotted on sonar.
    Superconducting fix

    You could widen their range if you had a magnetometer based on a superconducting quantum interference device, or SQUID. Superconducting magnetometers are exquisitely sensitive, but their promise has been limited to the lab. Out in the real world, they are quickly overwhelmed by background noise as minuscule as changes in Earth’s magnetic field caused by distant solar storms.

    Given that level of sensitivity, you can forget about mounting such a sensor on an airplane, for example. The US Navy gave up work on superconducting magnetometers to pursue less sensitive but more mature technologies.
    Learn more about quantum theory: In our expert talk at New Scientist Live in London

    The new magnetometer, built by Xiaoming Xie and colleagues at the Shanghai Institute of Microsystem and Information Technology, uses not one SQUID but an array of them. The idea is that by comparing their readings, researchers can cancel out some of the extra artefacts generated by motion. This “would be relevant to an anti-submarine warfare device”, says David Caplin at Imperial College London, who works on magnetic sensors.

    Although the announcement concerning Xie’s work has been removed, several of the previous papers culminating in this breakthrough are still available.

    The achievement points to an airborne device that can detect submarines from several kilometres away rather than just a few hundred metres. This would be catastrophic for NATO submarines, which have been honed to run ever more quietly, using clever technology that prevents them from being heard or detected on sonar. Their magnetic signature is much harder to eliminate.
    Noise problem

    Could China soon have the most sensitive submarine detector in the world? No Western navies are known to have SQUID detectors.

    Researchers estimate that a SQUID magnetometer of this type could detect a sub from 6 kilometres away, and Caplin says that with better noise suppression the range could be much greater.

    Not everyone is convinced the Chinese magnetometer is ready for deployment. Cathy Foley at CSIRO, the Australian government research agency, says there are several difficulties with turning a SQUID into a sub-hunter – for example dealing with background magnetic noise. Nobody has yet solved all of these problems, although she says the rate of Chinese progress means they may well be first to succeed.

    SQUIDs are only one of the ways that China has been upgrading its anti-submarine capability over the last few years. The “Underwater Great Wall”, a string of submerged sensors, buoys and drone submarines, is thought to be close to completion. The project will help China extend its offshore surveillance zone.

    Beijing has long wanted to change the rules of engagement in its waters. Earlier this year it drafted new laws requiring any foreign submarine to get approval before entering Chinese waters, and once there, to stay surfaced and display its national flag. “Can the Chinese make these systems work reliably while in motion in the air or underwater? We’ll be watching their progress closely,” says Foley.

    Chinese scientists claim to have made a major breakthrough in magnetic detection technology that could bring unprecedented accuracy to the process of finding hidden metallic objects – from minerals to submarines.

    The Chinese Academy of Sciences, the country’s largest research institute, said in an article on its website on Wednesday that a “superconductive magnetic anomaly detection array” has been developed in Shanghai and passed inspection by an expert panel.

    The experts were quoted as saying that the device, which works from the air, could be used to pinpoint the location of minerals buried deep beneath the earth in Inner Mongolia, for example, with a level of precision as high as anything currently available around the world.

    The device could also be used on civilian and military aircraft as a “high performance equipment and technical solution to resources mapping, civil engineering, archaeology and national defence”, the article said.

    China’s military may soon adopt the technology, if it hasn’t already, said Professor Zhang Zhi, an expert in remote sensing with the Institute of Geophysics and Geomatics, China University of Geosciences in Wuhan, Hubei.

    “The technology could be used to detect minerals on land, and in the ocean to nail down submarines,” said Zhang, who was not involved in the project.

    Anti-submarine aircraft have been equipped with magnetic anomaly detectors, or MAD, since World War II. The devices monitor the small disturbances metallic objects cause to the Earth’s magnetic field, analyse the data and use complex algorithms to calculate the object’s position.

    Precise locations are often difficult to obtain, however, because the strength of a magnetic signal drops rapidly as the distance from the source increases.

    Aircraft have to fly low, and the submarine has to be operating sufficiently close to surface for the device to register it. The power of the signal can be reduced by other factors, too, such as if the submarine is made from less ferromagnetic materials.

    Dr Lei Chong, an assistant researcher studying MAD technology at the Department of Micro/Nano Electronics, Shanghai Jiaotong University, said the Chinese device was different from conventional designs in at least two ways.

    The first is the large number of probes the device uses. With this “array”, it can collect much more data than traditional detectors, which tend to use just one antenna, said Lei, who was not involved in the project.

    The new MAD also uses a superconductive computer chip cooled by liquid nitrogen. This super-cool environment significantly increases the device’s sensitivity to signals that would be too faint for traditional devices to spot.

    “I am surprised they made such an announcement,” Lei said. “Usually this kind of information is not revealed to the public because of its military value.”

    The superconductive MAD array was developed over four years by a research team led by Professor Xie Xiaoming from the Shanghai Institute of Microsystem and Information Technology, according to the CAS article.

    Xie could not immediately be reached for comment.

    Chinese research teams have also recently completed the development of eight other types of magnetic detectors, some of which are small and sensitive enough to be used on satellites, the article said.

    The academy said that due to the difficulties involved in developing such equipment, most countries, including the United States, don’t yet have it. Germany is the rare exception, it said.

    Despite the article’s claims, Lei said it was too early to say whether China was leading the world in MAD technology.

    America’s hidden role in Chinese weapons research

    “The US military might have developed similar equipment but kept their lips sealed about it,” he said.

    “It’s impossible, therefore, to compare one country to another on this kind of sensitive technology based only on openly available information.

    “Converting a mineral detector to a MAD for submarines requires a lot of extra work. Military users have very different requirements to those in the civilian sector,” he said.

    Chinese scientists have claimed a major breakthrough in magnetic detection technology which could find hidden metallic objects, including minerals and submarines.
