China’s Noisy Subs Get Busier — And Easier to Track




The military’s latest secret assessment of China’s rapidly modernizing submarines has good news and bad news for the U.S. Navy. On one hand, the roughly 60 submarines in the People’s Liberation Army Navy (PLAN) fleet are spending more and more time on combat-ready patrols — signaling China’s increasing naval competence and growing seriousness about influencing the western Pacific Ocean.

On the other hand, the flurry of undersea activity gives American forces more opportunities to tail and examine Chinese subs. And U.S. analysts discovered a silver lining in the gathering strategic storm clouds. Chinese submarines are a hell of a lot noisier than anyone expected. The sound you hear is the Pacific balance of power tipping in Washington’s favor.

As recently as 2007, China’s diesel-powered subs and a handful of nuclear-propelled models managed just a few patrols per year, combined. Two years before that, none of Beijing’s undersea boats went on patrol. For years, the majority of PLAN submarines remained tied up at naval bases, sidelined by mechanical problems and a shortage of adequately trained crews.

As long as the PLAN’s submarines were idle, the U.S. Navy’s spy planes, surveillance ships and snooping subs had few opportunities to assess China’s undersea capabilities — and, most importantly, how much noise the Chinese generate while submerged and moving. Navies can use passive sonars to track submarines by the sounds they make. The louder a vessel, the easier it is to detect. And destroy.



With little information to go on, American intelligence officials had to guess. In cases like that, “you guess conservatively,” a respected U.S.-based naval analyst tells Danger Room on the condition of anonymity. The conservative estimates placed the latest PLAN subs roughly a decade behind the state-of-art for Russian submarines — and potentially 20 years behind U.S. undersea technology.

Now Chinese subs are patrolling more frequently. “Within the last year or two the Chinese have begun to deploy diesel boats more frequently into places like the Philippine Sea,” the analyst reveals. More and better data is flowing in from U.S. forces. With that data, the Navy conducted a fresh assessment of PLAN submarines. The unnamed analyst attended a classified briefing based on the assessment.

The assessment’s biggest surprise: Leaving aside the PLAN’s dozen imported Russian subs, new Chinese submarines can be detected at what’s known as the “first convergence zone,” a ring approximately 25 miles from an undersea vessel where outward-traveling sound waves pack close together.

During the Cold War, the U.S. Navy would arrange its own submarines in lines where each boat was 25 miles from the next, forming a sort of net to catch Soviet subs. With the introduction of the latest generation of quiet Russian diesel subs in the 1990s, the Americans thought that convergence-zone detection was no longer possible. But the Navy’s just discovered that China’s homemade subs are even louder than 20-year-old Russian boats. “Apparently they [U.S. subs] are making first convergence zone detections and holding them,” the analyst reports.

Assuming the Chinese stay with their current sub designs, American submarines should be capable of swiftly defeating Chinese boats in any potential future shooting war — helping clear the way for U.S. aircraft carriers to strike Chinese land targets. Combined with a slowdown in Chinese sub production, and the recent doubling of America’s submarine build-rate, the noise revelation could lead to a radical recalculation of the Pacific balance of power.

The U.S. Navy had a comfortable technological lead over the PLAN even before the increased Chinese sub activity fueled the recent intelligence coup. Now that lead has gotten even wider. And noisier.

China's aircraft carrier conducting sea trials


BEIJING, Dec. 28 (Xinhua) -- China's aircraft carrier is underway carrying out scientific testing, a spokesman with the Ministry of National Defense said Wednesday.

Spokesman Yang Yujun said at a press briefing that after attaining objectives during its previous sea trials, the vessel is now carrying out follow-up scientific testing as planned.

Yang said the scientific research and testing will be a long process, and relevant scientific testing and training at sea will continue in the future.

The spokesman denied a report that Russia refused to sell aircraft carrier arrester wires to China, which delayed the aircraft carrier's launch. "The report was entirely groundless," Yang said.

He said China's armed forces adhere to the principle of independent innovation in the development of weapons and equipment.

"The main equipment for our aircraft carrier, including the arrester wires, were developed and converted on our own," he said.

The aircraft carrier was originally built by the former Soviet Union. It was not yet complete when the Soviet Union dissolved in 1991. Ukraine disarmed it and removed its engines before selling it to China.

The vessel, measuring 304.5 meters long and 37 meters wide with a displacement of 58,500 metric tons, has been completely refitted for its new role as a research and training platform for China.

In recent years, the PLA Navy has been modernizing the level of its comprehensive combat power, and it has been actively promoting the holistic transformation of the navy structure, Yang said.

But Yang said it should be stressed that the strategy of China's inshore defense policy has not changed.

He said the Navy undertakes the tasks to defend national security at sea, safeguard sovereignty over territorial waters, and protect maritime rights and interests.

Currently, the United States, the United Kingdom, France, Russia, Spain, Italy, India, Brazil and Thailand operate a total of 21 active-service aircraft carriers.

Hier, le Quotidien du peuple, principal journal d’information en Chine, a publié en langue anglaise l’interview entre Lin Zhiyuan, expert sur les Etats-Unis à l’Académie des sciences militaires chinoise, et un journaliste du Quotidien de l’Armée de libération du peuple, au sujet du retour stratégique des Etats-Unis en Asie. En novembre, Barack Obama s’est rendu en Asie pour s’immiscer dans les conflits locaux et annoncer l’implantation d’une base américaine ouvrant sur la mer de Chine méridionale.

Des stratèges de l’US Navy sont très portés sur la théorie du géographe britannique Halford Mackinder de “terre du milieu”. Mackinder dit : « qui règne sur l’Europe de l’Est commande la “terre du milieu” ; qui règne sur la terre du milieu commande l’ “île mondiale” (l’Eurasie) ». Les disciples de Mackinder ont appliqué cette stratégie à l’Asie et pensent que contrôler la mer de Chine méridionale permettra à l’US Air force et à la Navy de commander l’Asie de l’Est et donc l’ “île mondiale”.

Halford Mackinder (1861-1947) est le fondateur de la géopolitique britannique qui ouvrit dès la fin du XIXe siècle l’ère des guerres mondiales utilisées par l’Empire britannique pour faire face à la montée en puissance industrielle et scientifique des Etats-Unis, de l’Allemagne et de la Russie. Mackinder est notamment l’inspirateur du géopolitologue allemand Karl Haushofer, dont le disciple Rudolph Hess introduisit pour le compte de leurs contrôleurs britanniques la doctrine du Lebensraum auprès d’Adolf Hitler.

Avec sa politique va-t-en-guerre en Libye, en Syrie et en Iran, sa volonté d’affrontement avec la Russie en implantant un bouclier antimissile en Europe de l’Est, et son offensive dans le Pacifique contre la Chine, Obama est l’idiot utile de l’Empire financier de la City de Londres. L’Empire britannique utilise le Président des Etats-Unis et son armée pour déclencher un conflit devant anéantir les grandes puissances qui sinon triompheraient de la faillite imminente du système.

Trés interessant

Merci, j'aime bien trouver des sources d'informations parallèles qui ont du fond, ça devient tellement rare.

A qui le dis-tu, cher Philippe...
En tout cas, belle trouvaille.

wa3ra 8adi..


Oui surement modernisation ou retiré du service..

Si ce n'est pas un totoshop, c'est une tentative de suide de l'équipage.

Celui qui fera ceci est quelqu'un de ... australien quoi,

on peut naviguer dans un etat pareil, mais avec cette vitesse, la coque peut encaisser des coups étant ... non cohérente.

mais aller à penser à submerger avec, ca n'a pas de sens, la réponse se trouver dans dans le fonctionnement d'un SM d'ailleurs, quel mécanisme va controller le mouvement de l'eau dans cette partie

La coque extérieure des SM à double coque est mince et ne supporte pas de différence de pression elle n’est que pour donné une forme optimale au SM. C'est la coque intérieure qui est pressurisé et qui supporte la différence de pression



De toute façon se SM devait être en fasse d’entretien ou modernisation lors de la prise de la PIC

Ou est la coque interne déjà ?

On constate quoi de ceci ?

Sinon, montres nous, comment CE SM peut immerger ? et comment il peut reprendre le surface ?

Et si c'était tout simplement 1 SM en maintenance ou en chantier qui fait des essais de navigations à la mer???
