Anyone hear that the massive military exercise going on in China now is an EMP attack simulation?

( Iam a Chinese high school student,my English is not good,so my sentences may have many mistakes.Please don't care about it)In 2014 Zhurihe exercise,the group army of Nanjing Military Region and Jinan Military Region had been attacked by nuclear weapon……I give you a Chinese website:

Chinese scientists are studying the applications of supercavitation to propel large bodies underwater at high speed. A team of scientists at the Harbin institute of Technology’s Complex Flow and Heat Transfer lab headed by Prof. Li Fengchen has come up with a new approach to create an ‘air bubble’ required for rapid underwater travel.



“We are very excited by its potential” Prof. Fengchen said, explaining that the unique attributes of the team’s new concept is the ability to control the vessel within the air bubble, without a rudder. Lack of steering and control has limited the application of this concept to unmanned bodies such as torpedoes, that were fired in a straight line because they had limited ability to turn. “Our method is different from any other approach, such as vector propulsion or thrust created by an engine” Li said.


Scaled up into a full size ‘supersonic submarine’, such vessel could make the distance from Shanghai China to San Francisco, CA in less than two hours


The supercavitation propulsion concept was explored in the Soviet Union in the 1960s, but implemented only with torpedoes (Shkval). In the US, applications are explored with hovercraft and counter-mine applications. (New Scientist Magazine, 7-2000) The Chinese team’s concept employs the application of a liquid spray around the underwater vessel’s body, creating a membrane on its surface, reducing the drag at low speed. As the speed reaches 40 knots (75 km/h) and higher the vessel would enter the supercavitation state. At this stage, the membrane that wraps the vessel would help with steerin by applying variable levels of friction in the appropriate axis. remain Wang said even he had been kept in the dark about recent supercavitation developments in China. “By combining liquid-membrane technology with supercavitation, we can significantly reduce the launch challenges and make cruising control easier,” he told the South China Morning Post.

The Russian Shkval torpedo could not easily steer underwater and would often be fired in a straight line.

The effective range of Russian supercavitation torpedoes (Shkval) that could travel at a speed of 200 knots (370km/h) was between 6-8 nm (11-15 km).

Here's another news on this supersonic submarine.

China working on supersonic submarine that could travel from Shanghai to San Francisco in '100 minutes'
Scientists at China's Harbin Institute of Technology are "a step closer to creating a supersonic submarine that could travel from Shanghai to San Francisco in less than two hours," reports The South China Morning Post. The scientists have reportedly succeeded in replicating an air bubble that would allow vehicles and projectiles — such as a torpedo — to travel more quickly through water, which produces much more drag than air.

In theory, a supercavitating vessel could reach the speed of sound underwater, or about 5,800km/h, which would reduce the journey time for a transatlantic underwater cruise to less than an hour, and for a transpacific journey to about 100 minutes, according to a report by California Institute of Technology in 2001. [SCMP]

Of course, there are some significant obstacles to the dream of traveling frictionlessly across the Pacific. For one, such a vessel would need an immensely powerful rocket to reach supersonic speeds, which in turn would create problems with steering. However, this new technology could prove useful in other ways. "[T]here's plenty of reason to believe a submarine could be built that would significantly exceed the speed of today's fastest models, which lumber along at a speed of 40 knots (about 46 mph)," writes Terence McCoy at The Washington Post.

Interesting speech that it specifically mentioned information warfare, mechanized warfare, and the Liaoning in the ways that it did.

BEIJING Sat Aug 30, 2014 9:04am EDT

(Reuters) - Chinese President Xi Jinping has said China will spur military innovation and called on the army to create a new strategy for "information warfare" as the country embarks on military reform, state media said on Saturday.

Xi heads the Central Military Commission, which controls the 2.3-million-strong armed forces, the world's largest, and is stepping up efforts to modernize forces that are projecting power across disputed waters in the East and South China Seas.

During a meeting with the ruling Chinese Communist Party's Politburo, Xi said China "must vigorously promote military innovation" but warned it will be difficult.

"When you compare military innovation to other forms of innovation, the demands are greater and there will be a higher degree of difficulty," Xi was quoted as saying.

"Faced with the severe challenges to our national security and stability and the deep-seated contradictions and problems with reform, it is even more pressing that we greatly liberate our ideas and concepts, have the courage to change our fixed mindsets of mechanized warfare and establish the ideological concept of information warfare".

Xi said the army must "strive to establish a new military doctrine, institutions, equipment systems, strategies and tactics and management modes" for information warfare.

The announcement by Xi could rattle many of China's rivals, including the United States. Officials in Washington have argued for years that cyber espionage is a top national security concern, and Beijing and Washington have confronted each other publicly about the issue.

In May, U.S. authorities charged five Chinese military officers with hacking into American companies to steal trade secrets.

A hacking attempt on a sensitive Canadian government computer network last month was similar to attacks mounted by an elite unit of the Chinese army based in Shanghai, according to a cybersecurity expert.

China has denied those charges, saying it is also a victim of cyber attacks.

In March, China announced its biggest rise in military spending in three years, a strong signal that it is not about to back away from its growing assertiveness in Asia, especially in disputed waters.

The spending increase appears to reflect Xi's desire to build what he calls a strong, rejuvenated China, even though the country has not fought a war in decades.

Xi also recently urged military leaders to speed efforts to get the country's sole aircraft carrier combat-ready.

Aside from the carrier, China is developing a range of high-tech weaponry, from stealth fighters to systems for shooting down satellites.

China’s Nanjing defense electronics technology group is unveiling a new phased array radar iterating in the VHF/UHF waveband, designed for long range air surveillance and target acquisition role. Operating in the long wave band – VHF/UHF enables the JY-26 to detect targets presenting low radar cross section (stealth aircraft) at the decimetric, centimetre and millimetre wave bands. The use of phased array technology also provides users the ability to increase the power transmitted at a certain location where a target presence is suspected, thus increasing the probability of detection of low-RCS targets.
