China developing 180,000-ton double-hull aircraft carrier

[tarunraju]

I'm no structural engineer, but that design doesn't make any sense. The carrier won't be sailing through still waters, and each of the two "hulls" will behave differently to the water around out. Dual-hull configs make sense for lightweight sailboats in which a sort of wishbone suspension balances load for the vessel. I can't imagine how a completely flat flight-deck can hold onto two hulls, especially of ~90,000 tonne displacement each.

The only way they can do it is building a deck on a supertanker. It makes sense actually as it is cheap. I don't see why $13 billion need be spent. The only problem is speed.

Yep. This design is a fanboy CGI from 2010. No idea why it keeps getting reposted.

Any AC built like this would see its flight deck warp, twist, or even crack open within 3 months of induction.

I dont know much about ships, but that picture is lol,..they glued two ships together with fevicol.

 

[ramakrishna]

Yes, Images looks too funny.. Looks like a perfect Chinese model :cool2: and looks like they Used feviquick for two different decks

As India got its 3rd world class air craft carrier in its fleet, I was thinking the same by Chinese people but not as funny as this one....

Speed will be major defect for this model, Worlds biggest and best Aircraft carriers -Nimitz Class Aircraft Carriers has some large vessels like USS Dwight D Eisenhower, USS Carl Vinson ,USS Theodore Roosevelt,USS Abraham Lincoln, USS George Washington.

frequently we here issues faced by this giant vessels with advanced technology lets see what happens
with the Chinese technology..

[debasree]

they have to put significant amount of vessel to protect it...& in conflict time it will be a soft target... let them built it..

 

[Vishwajeet]

Such a big target can be easily targeted by ANTI SHIP MISSILES unless you have high precision defense network like "AEGIS". (which CHINA still don't posses). Its not easy to escorts such huge AC's. Even India face lack of advance CBG's. at present we are using Delhi class and Talwar class (Best among their class) for escorts of AC's. and we know that's not enough.

Like wise China too face such issues, we all know most of their vessels are either old or do not posses technological advantage which IN have. (threads are available in forums if you want to get details). so, in such case any such carrier is highly vulnerable to enemy missiles. and if they are targeted by enemy missile, you can assume the huge loss i.e AC + FIGHTER at deck + STAFF + WARHEADS + "CONFIDENCE".

Qianzhan.com said in its report yesterday: China has to put an end to its old practice of following others countries' footsteps.

Sources say that through meticulous engineering and mechanical analysis, China will conduct research and development of the first 180,000-ton :shocked: double hull aircraft carrier in the world.

If successful, it will be a movable Chinese territory with maritime hegemony.

It will have a huge capacity, capable of carrying 125 J-20 fighter jets enough to destroy any existing aircraft carrier in the world.

Sources say that China conducts research into a 180,000-ton double hull aircraft carrier because compared with a monohull aircraft carrier, it has exceptional advantages.

A double hull carrier may have two identical runways for simultaneous taking off and landing.

In addition the diagonal runway on the existing Nimitz-class aircraft carrier is too short to be free of the risk of crash.

A double hull ship means hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks.

The space between the two hulls is sometimes used for storage of fuel or ballast water.

Double hulls are a more extensive safety measure than double bottoms, which have two hull layers only in the bottom of the ship but not the sides.

There are two type

As meticulous engineering, mechanical analysis, research and development as already done for US Navy HSV 2 Swift?

My idea of a triple hulled ac carrier with two runways was something like the littoral combat ship and figure-4 of the wiki link posted below.
Multihull - Wikipedia, the free encyclopedia

The central hull will have all the propulsive machinary and control stations while the side hulls will have auxillary stuff. Such a ship will be unsinkable by subs and seaskimming missiles as the main hull will always be protected by the side hulls from torpedos and missile while we can always flood the un damaged hull to maintain stability and continue ops. The area between the two runways will be used to park ac on deck thereby reducing the need for width and keep the ship small enough.

How will these military catamarans handle in heavy seas?

 

[rock127]

First Chinese build aircraft carrier a massive catamaran vessel and whats next a submersible aircraft carrier?

A flying submarine

Sir, multihull ships are more stable and can cruise at higher speeds and also remain stable at much higher sea states than monohulls. In my design, we can have the length of the ship reduced to just 250m as we will need 90m for cat launch and 100m for arrested recovery, while we can simultaneouly launch four ac and also recover two every one minute which is higher rate of operations than two parallel runways on shore. The max width can be just 70m as we won't need angled deck and the bridge of the ship can be moved right upfront in the center which is considered the best location for it on the central hull without hindering deck ops.

don't understand why ppl still argue over this, obiviouslly this is fake. china don't have intention or tech to build something like this right after they have their 1st carrier, which is completely different from this article

 

[sayareakd]

have they make their first AC ??

 

[bennedose]

Interesting news. Many thoughts come to mind

1. Maybe the J-15 (Su 33 clone) needs a long long runway so better to have a huge ship
2. China was the country that developed an ICBM to take out a carrier. Now US carriers are big targets. This behemoth will be a bigger target - so the Chinese must be confident that such big targets won't be hit by someone else doing a tit for tat anti carrier ICBM. Does that mean that their own ICBM to take out carriers is not working so well against carrier sized targets?

first let them make regular carrier, then go for this dream carrier.

 

[jmj_overlord]

chinese commissions russian built aircraft carrier and labels it "made in china", now they are "developing" 180000 ton double hull aircraft carrier..........................interesting

China to build six aircraft carriers by 2020

Elite Reference magazine says in its report Frigates of Chinese aircraft carrier battle group secretly assembled at the military port for aircraft carriers, "The Soviet aircraft carrier Ulyanovsk, though failed to be commissioned, leaves experience and lessons which may provide China reference in China's pursuit of nuclear aircraft carriers."

I have revealed in my posts that China's first aircraft carrier the Liaoning has recently set sail for the sea for training, especially landing and taking-off of aircrafts on it, and that China has begun research projects for the development of its own nuclear aircraft carriers.

Please refer to my posts: "China: Aircraft Carrier Sets Out for Landing and Taking-off Training on the Sea" on June 12 and "China: PLA on course for nuclear-powered aircraft carriers" on February 22".

Elite Reference magazine says, "There has been analysis that China will carry out its plan for aircraft carrier construction by stages. At the first stage, four conventional carriers will be built; while at the second stage, at least two nuclear carriers will be built. They are expected to be delivered to Chinese navy around 2020."

It says that according to Hong Kong's Asia & Pacific Defence Quarterly, the Soviet Union completed the design of its nuclear aircraft carrier Ulyanovsk, which was dismantled halfway in construction due to lack of funds. However, they had already completed building two of its four nuclear reactors by that time.

The magazine is of the opinion that China cannot obtain technical information about a nuclear aircraft carrier from the West. However, Russia and Ukraine, where the Ulyanovsk was built, can teach China how to build a nuclear aircraft carrier based on their experience in building the Ulyanovsk.

China will certainly want such expertise from them. As both Russia and Ukraine are under economic pressure and have strategic demands, it is very difficult for a third party to prevent the two countries from providing China with assistance.

No idea how they can build 6 in just 7 years.
