Am I right in thinking that if the pointy end has a ski jump there will be no catapults there. There was a lot of speculation re EMALs being installed a couple of years back, have the Chinese decided it's too difficult or would they be content just to have catapults on the sticky out bit in the middle?

As per the report at the end; 01 is the first home built and stays with the technology they inherited; 02 is being built with EMAL catapults; 03 adds nuclear powered.

See post #21 for the sections of the hull for 02 with notches for the catapult.

Hmmmm. This thread was begun in 2007 (now nearly a decade ago!) with the prediction of a home grown CVA by 2010. And seven years after the predicted date, still no operational home grown CVA. Clearly, building a CVA is a much more difficult undertaking than most folks appreciate. And then assuming that was done, equipping such a CVA with an air wing is also very difficult, and then actually operating the CVA and its embarked air wing effectively and safely is even more difficult. It'll be interesting to see how much money the Chinese will be willing to sink into this effort.

My fairly confident prediction would be - as much as it takes.

Two years from start to launch?

China's second aircraft carrier to be launched soon - CCTV News - CCTV.com English

China's domestically-made aircraft carrier is currently being fitted out and will soon be launched, according to a spokesperson from China's Ministry of National Defense, who gave no further details. The spokesperson, Wu Qian, made the response at a regular news briefing on Thursday in Beijing.

Earlier reports suggested that the carrier might be launched on April 23, when China celebrates the founding day of the Chinese navy. The Chinese defense ministry announced plans to construct the new aircraft carrier, built by China itself, in late December 2015........

Love the patronizing comments on here about China and its shipbuilding.
We used to say the same about Japanese cars around about 1972 when the OK dealership started distributing them. Just before they utterly trounced us at making them and selling them. And they just got better and at it...
19th Century was Britain's and the 20th was the USAs. 21st is China's. So suck it up.

That's an interesting debate. On some accounting the age of empires is compressing and, in main part due due to the one child policy, Chnina compressed it into 2 decades - and is already into the Japanese syndrome of an aging population with no next generation to support them, let alone carry on expansion.

In that theory the rising nation is India, not China.

You gotta hand it to them ...

The enormous dry dock (1200 ft by 270ft) at Dalian, out of which they just floated the Type 001A Shandong CV17, did not exist ten years ago. In the last ten years, they built that dry dock from scratch, then used it to assemble at least two very large (1100 ft long) cargo ships, rework the Liaoning CV 16 and then assemble the Shandong. All since 2006.

The first Type 002 70,000 ton CV 18 (alleged steam catapults and arrester wires) is already in ‘recognisable shape’ in the 1150 by 300 ft Hudong-Zhonghua twin dry dock on the Huangpu river in downtown Shanghai.

There are three other bigger dry docks (up to 1800 ft by 380 ft) in operation at the Jiangnan shipyard on Changxing Island just across the Yangtse from Shanghai. I don’t think they existed twelve years ago. ............ You gotta hand it to them.

Breakthrough to power most advanced jet launch system on China’s second home-grown aircraft carrier

A technological breakthrough in naval propulsion will enable China’s second home-grown aircraft carrier to use the world’s most advanced jet launch system without having to resort to nuclear power, overcoming a huge hurdle in the vessel’s development, military sources said. The development of the integrated propulsion system (IPS) would allow the vessel to be more efficient, allowing more power for an electromagnetic catapult, rather than a less technologically advanced steam-driven catapult launch system, the sources said.

China’s first two carriers, the Liaoning and its sister ship, the Type 001A, are conventionally powered vessels equipped with Soviet-designed ski-jump launch systems. But an electromagnetic aircraft launch system (EMALS) on the Type 002, China’s second home-grown aircraft carrier, would mean less wear and tear on the planes and allow more aircraft to be launched in a shorter time than the ski and steam-catapult systems. According to a source close to the People’s Liberation Army, China’s Central Military Commission was keen to use EMALS on the Type 002. “[But] the obstacle … was whether a conventionally powered carrier would be able to support EMALS, and now that problem has been solved,” the person, who is close to the PLA’s equipment department, told the South China Morning Post.

The solution was provided by a team led by China’s top naval engineer Rear Admiral Ma Weiming, which developed a medium-voltage, direct-current transmission network to replace an earlier system based on alternating current. As a result, the CMC, which is chaired by President Xi Jinping, has said the development of the Type 002, which had long been delayed, would get under way “soon”, the source said.



Wang Ping, an expert in military technology at the Institute of Electrical Engineering under the Chinese Academy of Sciences in Beijing, said the innovative design meant that high-energy consuming launch systems and weapons could now be used on a vessel driven by conventional power. It wasn’t just a simple switch from alternating to direct current, but a complete overhaul of the energy supply and distribution system – from steam boilers to the energy storage device,” he said. Wang added that in the future, the same technology could be used to launch not just aircraft, but also missiles and satellites, and maybe even power high-speed trains.

A naval expert close to the carrier project confirmed that the CMC was now planning to proceed with the new power option. “China doesn’t need to copy the United States and use nuclear reactors to support EMALS and other energy-hungry weapons on the ship, because it now has more advanced technologies to solve the problem,” the naval expert said.... “China now has mature technologies … [and] the PLA is narrowing the gap with the US,” the naval expert said. He added that the US used an integrated propulsion system on its first USS Zumwalt-class destroyer, which was launched in 2013, but that it was not as advanced as the second-generation technology developed by Ma and his team.

In March, Ma, who is based at the PLA Naval University of Engineering in the central China city of Wuhan, told state broadcaster CCTV that the “ultimate aim” of his work on the IPS technology was to “solve the problem of deploying high-energy weapons” from ships. He also said on the sidelines of the annual National People’s Congress in Beijing that China’s EMALS technology was more advanced and more reliable than the system used on the nuclear-powered USS Gerald Ford supercarrier.

The world’s largest and most expensive super warship – and the first to use both EMALS and advanced arresting gear – completed its maiden arrested landing and launch operation in late July, a week after its commission to the US Navy.

makes sense - I'm sure that a decent trawl through all the published data plus a little bit of industrial espionage suggests that EMALS and a DC current system is a lower risk and can be achieved faster than trying to develop a bigger sea-going N power plant

Leave that to the submariners for now

I personally don't understand why a nuclear power plant is required for EMALS. EMALS was tested for years ashore with no nuclear plant. And current large civilian cruise ships generate huge amounts of electrical power for hotel services and propulsion without resorting to a nuclear power plant.

The main advantage of the nuke plants in US carriers is that the tankage used to store ship's propulsion fuel can instead be used to store aircraft fuel. They also allow the carrier to steam at sustained high speed for long distances to quickly arrive at a distant trouble spot without resorting to refueling enroute and arriving there ready to generate a large number of aircraft sorties.

And as an aside, the biggest reason US carriers are nuke powered is law. Congress passed a law in the 1970s mandating carriers be nuke powered.
