Diaoyu Islands appeared complicated situation now is actually the result of American Terrier, the despicable tactics Amur U.S. said the Diaoyu Islands have been Amur clear this. Japan hostile contradictions of the Diaoyu Islands issue has escalated to the living room seems not adjustable, but it is still not expected in the United States. The United States wanted the war broke out between a contention Island comprehensive war or even a Sino-Japanese showing interest, according to Russia's "Kommersant" reported on December 20 powered submarine "Amur -1650" type.

If the boat what characteristics worthy of Chinese procurement, it certainly is the inheritance before the Russian-made submarines better quiet performance. China's submarines have been criticized by the outside world is too much noise, the U.S. daily said the Chinese submarine at sea can be heard as far away as Vietnam.

However, it may be more refers to the older 033 and 035 submarines, these submarines in service too long, the power system after several overhauls, thus and many domestic diesel engine noise increased substantially after the overhaul, in the absence of drop , can be described as deafening noise measures. Especially outward when touring in these submarines surface of the water, mostly at full speed, the noise reached the maximum, no wonder they are set in the first island chain in the United States and Japan underwater sonar detected easily.

The 039 and 041 have been built in recent years in China significantly reduce the noise. These new construction of conventional submarines, Unlike old submarine before, using imported technology diesel engines in Germany or abroad, and using a variety of noise reduction technology, damping floating raft, noise reduction pipeline, and hull silencer tile, etc., thus mute nearly foreign submarines.

Despite this, however, appears to be compared with the Russian-made submarines, there is a certain distance. Although China has learned a lot through the introduction of the Russian-made 636 "Kilo" class quiet technology in Russia, but the Russian people in the export of this type of submarine, or its done a lot of technical processing, is the boat mute Russians scaled down, the originally advanced technical mute does not completely.

Said that Russia in manufacturing submarines sold to China, the use of low-end products or modified mute a serious decline in performance technology, resulting in noise levels of the type of boat used in China is much larger than Russia's own use models.

Therefore look submarine mute technology from Russia, but not the top, the late production of submarines also applied Russia mute technology, can be difficult to achieve the level of Russia. Therefore, the 041-type "meta" class submarines equipped with China R & D aip technology is very advanced, but mute technically it is not the best.

"Lada" class submarines is a conventional submarine finally completed the development of Russia's post-independence, since the end of the last century began the construction of the first boat, "St. Petersburg" was incorporated into the Russian Navy probation until May 2010. Obviously, the boat encountered technical obstacles, leading to the construction process dragged on, and almost at the same time to start the second, the third ship is still in construction.

Russian Navy are not satisfied with the trial of the "St. Petersburg" submarine, because its power plant does not meet the requirements of performance, improved power system, the subsequent two after a work stoppage began to rebuild, but equipped with Russian-made first set aip power plant, the first boat, the earliest in 2014 may be completed and delivered. So, in fact, the boat applications power technology is not mature, perhaps India and other countries eventually abandoned the procurement of reasons.

The Chinese procurement four, but does not use the aip power in Russia, apparently also understand the weaknesses of the boat, before the signing of the agreement when aip require China's own production technology. From this point of view, China is indeed phase of the boat excellent quiet technology, the purpose of this large-scale procurement is the use of China's the aip power, combined with Russia's advanced quiet technology, which combined a with underwater long voyage and quiet performance and excellent aip powered submarines.

Aip power favored reason why Canada, which is both the trend of today's conventional submarines, but also the surrounding aip submarines have put into service the results. As we all know, aip submarines commonly known as quasi-nuclear submarines, not only submerged capacity similar to nuclear submarines, more importantly, is the underwater mute ability to make very good combat effectiveness. The submarine is to rely on covert attack weapon for victory, any submarines to be the idea of concealed himself, in an effort to achieve the suddenness of the attack, in order to achieve maximum operational goals.

To covert own best way is to reduce their noise, the hidden nature of submarine life, reduce noise is to increase the vitality of the submarine. It is estimated that the submarine underwater noise each reduced by 6 dB, the enemy's passive sonar detection range can be cut by half, while the passive sonar detection distance doubling.

Russia, well versed in this technology in the design of almost all submarine are attached great importance to the quiet performance and can be described as the world's most stringent mute measures used for this purpose. Allegedly using a variety of noise reduction measures, only about 100 to 105 db Amur -1650 "level of noise, very close to the ocean background noise. The reason why China insisted on purchasing this type of submarine, fancy mute technology compared to Japan and South Korea the latest submarine has certain advantages.

Conventional submarine technology has been advanced in Japan, the "black dragon" class appearance design draws on the principle of bionics, modeled on the shape of the halibut pure streamlined hull design to reduce the noise caused by the flow of water in the hull junction and resistance , also use the advanced the aip technology, FastLane as silent as undersea reef.

Therefore, according to the technical level of Japan earlier judgment "black dragon" class noise value between 105 to 110 decibels. Such an advanced technology, mute if the encounter with the Chinese submarine in the Western Pacific and the East China Sea, the Chinese submarines have not entered the war zone, Japan had detected, or even if it is difficult to find its traces, so it would be dangerous .

Meanwhile, Korean introduced German 214 aip submarines, its exterior design focus on the optimization of the fluid dynamics and minimize the opening in the boat on the surface, coupled with a large number of absorbing material coated with, thereby reducing the probability of the enemy to detect the reported probably between 110 to 115 decibels of noise, only slightly lower than the 041 type "class submarines. Therefore, if the China's submarine mute technology does not work, not to mention the Japanese submarine bucket, and even South Korea's new submarines, China is also difficult to prevail.

From this point of view, China is indeed phase of the boat excellent quiet technology, the purpose of this large-scale procurement is the use of China's the aip power, combined with Russia's advanced quiet technology, which combined a with underwater long voyage and quiet performance and excellent aip powered submarines.

Careful comparison of the "Amur -1650" type and the Japanese and Korean submarine comparison, can be found hidden on ATK is better than Japan's "black dragon" class and the Republic of Korea Type 214 in the advanced nature of the hull structure, anti- Shen, power plant and the development potential of the three are almost the same, automation systems and electronic devices, "black dragon" class and Type 214 is superior to the Amur -1650 "type.

Taking all factors point of view, although each of the three types of boats the advantage, but no doubt the Amur -1650 "integrated performance to be slightly better than" black dragon "class and 214-type one chip. If you use the advanced mute technology and weapons systems in Russia, combined with the relatively advanced automation systems and electronic devices as well as aip technology, then, there may be compared with Japan and South Korea the upper hand, perhaps China and Russia decided to joint production and procurement Amur -1650 "type submarines main reason.

According to the analysis of Russian military experts, China may exceed India became the first purchase of the submarine "Amur -1650. India has been previously considered to be the country most interested in the level submarine Later, however, the interest in India began to change, France or other countries prefer to purchase. And China, it is impossible to buy from countries outside of Russia mainly military, therefore, it is expected that equipped with Chinese-made "heart" and "brain" of the "Amur -1650 type submarine foreign users, almost China has no doubt.

Amur -1650 "type submarine jointly developed by China and Russia in the equipment, is expected to rapidly enhance the the Chinese submarine mute technology, if nothing else, then" Amur -1650 "submarine successfully improved the experience is likely to be used in China 041 type "meta" class submarines of further the mute technical modifications.
