China ready to build aircraft carrier

Hong Kong, China — Shipbuilding experts from Eastern Europe have confirmed that China will start to build its own aircraft carrier this year, as preparations for the project are complete.

The experts had visited the No. 3 military dock of the Changxing Island Shipyard – the new location of the Jiangnan Shipyard, known as the cradle of China’s defense industry – based in Shanghai, where they acquired exclusive photos of the interior of the shipyard. From these it can be deduced that China is ready to commence building the aircraft carrier at this dock.

Chinese armed police have dramatically strengthened their watch on Dock No. 3. All the entrances to and exits from this dock are under armed police guard, with plainclothes police on patrol. In contrast, the entrances to Dock No. 1, where civilian ships are built, are guarded only by shipyard security staff.

Dock No. 3 is 580 meters long, 120 meters wide, and completely encircled by a wall at least 2.5 meters high. A giant gantry crane has been built, with a capacity to lift at least 600 tons. The dock is large enough to build a medium-sized conventional aircraft carrier similar to the Russian Admiral Kuznetsov class with a light load displacement of about 50,000 tons.

The outfitting quay for No. 3 Dock has been finished and includes a large gantry crane. According to the Eastern European sailors who visited the shipyard, the quay is 8 kilometers long, and was finished in the autumn of 2008.

A number of large containers have been shipped to the area near the dock. Among senior shipbuilding experts from Germany, France and Italy who examined the shipyard photos, one suggested the containers might be loaded with oxygen supplies and power-generating equipment, as huge amounts of oxygen and power would be required for welding engineering.

An Eastern European source familiar with the aircraft carrier project said China had invested 35 billion yuan (US$5.1 billion) in the facilities at Changxing Island, including three gigantic joint-structured indoor assembly workshops in which the separate sections of the carrier would be built.

The expert from the French shipbuilding industry said these facilities could be used for processing steel plates and section materials, or the preliminary treatment or assembly of separate sections of the carrier.

Sources say that the shipyard and all its facilities were built at a very fast pace. A separate road network was finished around January 2007, to provide safety and security for the project. Despite attempts at secrecy, many residents of the nearby Changxing township knew that the shipyard was being readied to make China’s first aircraft carrier.

The facilities include numerous five-story buildings – accommodations for nearly 60,000 peasant laborers hired to build the aircraft carrier facilities – that have been in use since early this year. A correspondent for Kanwa Defense Review visited the area to interview peasant workers recruited for this project. The workers said they were paid from 3,000 to 4,000 yuan (US$440 to $585) per month, which is three or four times what an ordinary laborer in Shanghai can earn, and that their living conditions were very good.

The round-shaped headquarters building was to be finished this spring. Free-standing residential buildings in red and grey have been constructed for the shipbuilding experts. Satellite photos show that these houses are quite luxurious.

Judging from the size of the three gigantic joint-structured indoor assembly workshops affiliated to Dock No.3, it is fully possible that the separate modules of the ship will be built in these workshops and finally assembled at the dock.

Sources claim that China intends to build, equip and launch its first aircraft carrier – internally named “Beijing” – between 2009 and 2015. It is possible that the process could take longer, however.

The first steps will include the processing and cutting of steel plates and section materials as well as the assembly of sectional parts. When the keel is laid down it will be difficult to keep it secret, as the keel of the aircraft carrier must be towed to the dock in one piece.

June 3 is a date worth watching, as that day will be the Jiangnan Shipyard’s 144th anniversary. It is part of Chinese culture to mark anniversaries in a special way to bring good fortune. Therefore, China may take the opportunity to officially launch the aircraft carrier project on this date.

Novo SSBN chinês é mais ruidoso que seus similares russos da década de 70


A nova classe “Jin” (Type 094) de submarinos nucleares de mísseis balísticos (SSBN) é mais ruidosa que os submarinos russos das classes Delta III e Victor III da década de 1970, ou seja, um nível de ruído de submarinos de 30 anos atrás. A informação é do Office of Naval Intelligence (ONI), Serviço de Inteligência da Marinha dos EUA.

O gráfico abaixo mostra onde se encaixaria a classe “Jin” no espectro de nível de ruído das principais classes de submarinos chineses e russos. A parte verde da seta indica os mais fáceis de detectar e a vermelha indica os mais silenciosos e difíceis de ouvir.



É interessante observar como a Inteligência Naval americana obteve esses dados sobre a classe “Jin”. Provavelmente com o emprego dos navios SURTASS (um deles, envolvido num incidente próximo às águas territoriais chinesas) ou submarinos nucleares de ataque que seguiram de perto o primeiro Type 094 em suas provas de mar.

O elevado nível de ruído da classe “Jin” de SSBN coloca em xeque a capacidade nuclear de retaliação da China, pois esses submarinos poderão ser detectados e afundados antes que possam lançar seus mísseis balísticos.

Por outro lado a China tem avançado bastante na discrição dos seus submarinos nucleares de ataque (ver no gráfico a nova classe Type 095 próxima da “Akula” russa) e especialmente, nos seus submarinos convencionais (SSK). Ver gráfico abaixo:

Mystery Chinese SSK fuels Asia's submarine race

The China Shipbuilding Industry Corporation has launched an unidentified new-type conventional submarine (SSK) at its Wuhan shipyard, according to Chinese reports.

It is the third new SSK design revealed by China since 1994 and is likely to exacerbate regional anxieties that are propelling many Asian states to increase or establish submarine fleets.

Vague or altered internet images of this new SSK, which first appeared on the popular Chinese CALF web page on 10 September, led observers to think that it may be yet another Chinese internet hoax, but the submarine's existence was confirmed by much clearer images on 13 September.

While not much larger than the 3,000- to 4,000-ton Type 041 Yuan class, the new boat appears to incorporate Russian design influences, including a stouter hull with a reduced aft taper similar to the Project 667 Lada/Amur class, plus an elongated sail and hull-mounted retractable hydroplanes similar to the Project 636 Kilo class. However, in contrast to the sail of the Kilo, the new Chinese SSK incorporates hydrodynamic elements such as an intricately-faired leading edge with concave and convex curves

Uma questão aos colegas que sabem um pouco mais do que eu acerca desta área (o que não é dificil), a mim parece-me que a Marinha Chinesa está a ficar relativamente bem equipada a nivel da frota de superficie, mas que a sua frota de submarinos ou é com modelos velhos ou com modelos velhos modernizados/recalchutados.

The uninvited guest: Chinese sub pops up in middle of U.S. Navy exercise, leaving military chiefs red-faced
By MATTHEW HICKLEY

Last updated at 00:13 10 November 2007

When the U.S. Navy deploys a battle fleet on exercises, it takes the security of its aircraft carriers very seriously indeed.

At least a dozen warships provide a physical guard while the technical wizardry of the world's only military superpower offers an invisible shield to detect and deter any intruders.

That is the theory. Or, rather, was the theory.


Uninvited guest: A Chinese Song Class submarine, like the one that sufaced by the U.S.S. Kitty Hawk

American military chiefs have been left dumbstruck by an undetected Chinese submarine popping up at the heart of a recent Pacific exercise and close to the vast U.S.S. Kitty Hawk - a 1,000ft supercarrier with 4,500 personnel on board.

By the time it surfaced the 160ft Song Class diesel-electric attack submarine is understood to have sailed within viable range for launching torpedoes or missiles at the carrier.

According to senior Nato officials the incident caused consternation in the U.S. Navy.

The Americans had no idea China's fast-growing submarine fleet had reached such a level of sophistication, or that it posed such a threat.

One Nato figure said the effect was "as big a shock as the Russians launching Sputnik" - a reference to the Soviet Union's first orbiting satellite in 1957 which marked the start of the space age.

The incident, which took place in the ocean between southern Japan and Taiwan, is a major embarrassment for the Pentagon.


The lone Chinese vessel slipped past at least a dozen other American warships which were supposed to protect the carrier from hostile aircraft or submarines.

And the rest of the costly defensive screen, which usually includes at least two U.S. submarines, was also apparently unable to detect it.

According to the Nato source, the encounter has forced a serious re-think of American and Nato naval strategy as commanders reconsider the level of threat from potentially hostile Chinese submarines.

It also led to tense diplomatic exchanges, with shaken American diplomats demanding to know why the submarine was "shadowing" the U.S. fleet while Beijing pleaded ignorance and dismissed the affair as coincidence.

Analysts believe Beijing was sending a message to America and the West demonstrating its rapidly-growing military capability to threaten foreign powers which try to interfere in its "backyard".

The People's Liberation Army Navy's submarine fleet includes at least two nuclear-missile launching vessels.

Its 13 Song Class submarines are extremely quiet and difficult to detect when running on electric motors.

Commodore Stephen Saunders, editor of Jane's Fighting Ships, and a former Royal Navy anti-submarine specialist, said the U.S. had paid relatively little attention to this form of warfare since the end of the Cold War.

He said: "It was certainly a wake-up call for the Americans.

"It would tie in with what we see the Chinese trying to do, which appears to be to deter the Americans from interfering or operating in their backyard, particularly in relation to Taiwan."

In January China carried a successful missile test, shooting down a satellite in orbit for the first time.

First Chinese aircraft carrier nears completion

CHINA'S first aircraft carrier, built on the hull of an abandoned Soviet warship, is nearing completion, according to Western analysts.

The arrival of China as a member of the carrier club would be the most potent symbol of the country's burgeoning military power, even if its first model is based on a rehashed version of a warship that was never finished by its original owners. The Soviet Union collapsed before work could be completed.

The Varyag is expected to make its maiden voyage next year or 2012. "Photos regularly reveal an increasing tempo of work on the Varyag," Richard Fisher, an authority on the Chinese military at the International Assessment and Strategy Centre in Alexandria, Virginia, said yesterday.

"The island (control tower) is being much modified and a new Chinese radar system has been installed. We know little about its engine but it appears work has been proceeding on that as well."

The 300m warship was bought from Ukraine, which had acquired ownership when the Soviet Union was dismantled, and in 1998 it put the ship up for auction. China bought it for $US20 million and it was expected that the vessel would be turned into a casino.

For decades, China had disavowed any ambition to build aircraft carriers, but in more recent years, as the nation's economy has been transformed and Beijing has adopted a more muscular approach on the world stage, military officials have acknowledged the possession of a carrier fleet is crucial for the country's status.

It is likely the Varyag will be used as a training platform. It is believed China is planning to have multiple carriers by 2020.

Beijing is also ramping up production of unmanned aerial vehicles in an apparent bid to catch up with the leaders US and Israel in developing technology that is considered the future of military aviation.
