PLAN Carrier Construction

I can answer this question with much authority. You've partly answered your own question actually. The island has four primary purposes. Location of sensors i.e radars, navigational sensors etc, you have the bridge, the pri-fly and in on nuclear power carriers the funnel and exhaust venting system to clear the smokes etc... and actually a good vantage point IS crucial!

What you suggest is thereotically possible however all the towers, antennas etc potruding out of the deck would make it very cluttered and doesn't really save much real estate so might as well go with an island where everything can be centralized and extended from.
Also I think you always need that human eye in the sky both in the bridge and the pri fly to direct traffic and assess deck handling and operations. A camera no matter how good can't replace a human eye and definitely can't be a substitute for situational awareness.
On non conventional carriers there is also the issue of smoke. If you have everything 'flat' that means the stack is flush with either the deck or of the side. This would cause major issues since the smoke would get in the way especially if the wind blows the wrong way not just in terms of visibility but it's hot!! and the area where the vent comes out from would be non use anyway so either way you're still losing real estate. If you vent them to the aft then what happens on landing? the last thing a pilot wants to see when landing on a flat top is a big cloud of smoke right in front of him!!!

Last but not least what if there are technical issues with the cameras? You're basically mission killed if you can drive the ship and launch aircrafts! It doesn't even have to be anything serious. Something as trivial as a couple of seagulls doing business on the camera lenses or housing would basically put the entire carrier at risk!
Driving a carrier with just cameras is like flying a drone. Can it be done?? sure.. can you fly and navigate a drone? obviously!
Can you knifefight in a drone against another fighter piloted by a human being inside the cockpit and win? NO WAY!


Ah, the cult of the eyeball thrives still.

Well, I'm going to have to give you and the Eng five stars each on your posts, both very well written and to the point, I can't believe I learn something everytime you guys open your mouth,,,, or er??? plug in the data, keep it up, this could win the post of the day though, it is a keeper, one that could be stickied as a classic, I just never thought about how much thought had to put into building/operating an aircraft carrier, WOW! good job gentlemen,,,

Okay guys, this has gotten off topic and continues to head that way.

This thread is about actual PLAN projects and plans to construct an indegenous carrier. Pictures of that discussion, discussion of those projects actual plans. Discussions about the Liaoning refit as a part of that, etc. It is not about fan art of what a carrier might look like.

We have a thread for that:

Future Aircraft Carrier Design, Ideas, Brainstorm

I am moving these fanboy art discussions there. Please continue that discussion there if you so desire.

In the mean time:

I just looked at the building times for similar sized flattops to Liaonang, supposing that the ships rumored to be building in Shanghai and Dalian are of similar size. QE II class takes about four years from "keel laying" to launch, Forrestal and Kitty Hawk classes three and a half. Forrestal itself took three and a half years. We might expect the Chinese ships to take the same time, until mid '17. Indeed more modern production methods might even reduce this time. Outfitting took less than a year in the 'fifties and sometimes takes more than two years for Chinese destroyers. I think they will be commissioned well before 2020 but there might of course be delays.

I agree delft.

If they start these two carriers this early this year, I expect the will launch before 2018, and be commissioned before 2020.

This will give us all a LOT to discuss as they are building and we start seeing various features.

Particularly if the PLAN adds an LHA in their building queu too.

Looking forward to watching all of that happen.

QE would be the best indicator for the likely rate of progress for building Liaoning successor. Both are being built by ship builders without prior (comparable) experiences in building very large modern combat vessels.

Not entirely true.. BAE Maritime Systems have had experience working on the Ocean class LHD, the Albion LPD and the Bay class LSDs. While I agree those ships are not as big or complicated as QE, they are not exactly tugboats or small ships either.

The QE II program produces two vessels without thought of further production by a country with a limited shipbuilding capacity. Parts of these vessels are produced all along the UK coastline.
The Chinese vessels are the first of probably a long line of vessels for whose production large investments will have been made these last years. China has one of the largest shipbuilding industries in the world. Thinking of the development of shipbuilding technology in the last half century we shouldn't be surprised if three and a half years would prove to be a considerable over estimate. Concerning the matter "large modern combat vessels" that plays out mostly during the fitting out phase.

Further thoughts:
Last year the trading in the shares of one of the two largest Chinese shipbuilders, CSSC - owner of Jiangnan Shipyard among many others - IIRC, was interrupted from May to August because of the need to reach agreement with the government about investment concerning the production of naval vessels. If it now appears that both the Jiangnan Shipyard as well as the CSIC shipyard in Dalian will build a flattop. This suggest that the Dalian yard was preparing to to build one and had been investing for years to that purpose and that the government added the Jiangnan Shipyard early last year. In view of the vast investment necessary ( proven by the fact that months were needed to hammer out the agreement ) the reason cannot have been to make use of a temporary slack in orders. Also however fast these ships might be built the decision cannot have been based on political circumstances at the time.
One possible reason is that success of the tests with Liaonang showed that China didn't need a second experimental ship before committing to large scale production. An additional reason might be progress with the development of the EM cat. These would then be built into the new vessels and next also introduced into Liaonang. This is also suggested by the delay of the start of the refitting of Adm K from 2014 to 2018. She too might then be given Chinese cats.
What of the future? I don't think China will continue to have two yards churning out aircraft carriers. Perhaps this concerns say four ships altogether after which one yard switches to LHD's and/or helicopter/UCAV carriers and the other to nuclear propelled aircraft carriers, I hope with thorium molten salt reactors
