PLAN Aircraft Carrier programme...(Closed)

Going back a few posts, there was a link to China building a mulithull aircraft carrier. I do not know if they will build one or not, however the drawings are not very good.

If I may elaborate. The deck of an aircraft carrier can be divided into landing area, take-off area, and aircraft storage.

In a catamaran type carrier, you can get two decks parallel, one is for landing, one is for takeoff, the area inbetween is for aircraft storage and elevators. Thus the decks do not have to be angled. Angled decks on this layout simply add weight. Additionally because there is a full length deck that can be used for takeoff, aircraft can take off from the stern, not have way as they are doing now, this means they have more distance to accellerate and hence can get a higher take-off speed and hence carry for fuel/ordance.

A catamaran carrier means heaps of deckspace, but also more weight, because deckspace is huge there is no reason for overhangs, (port and starboard), as these overhangs just add weight. Because 2 decks allow aircraft to take off from the stern, and use the full lenght of the deck for takeoff, the vessel can be a bit shorter than a conventional monohull everything else being equal.

It's called fan art...

The Indian carrier is intended (whether realistically or not) to be an operational fleet unit right away. Liaoning will be an experimental/training unit for some time. Their shake down and work up schedules would be vastly different.

A closer approximation to how Liaoning might shake down and work up could be the Kiev, during the early 1970s.

The Indians intent the Vikramaditya to be a full fledge carrier that's going to be out on patrol and if necessary fight wars. The Chinese at least in public are saying that the Liaoning is intended to be a platform for "scientific testing and research". The Indians have been operating carriers since 1961 so they have more than 50 years of experience operating carriers. They have also recieved help and cooperation from the Americans and the Russians in carrier ops training.

But having said that the Indians have been operating VSTOL carriers for more than 30 years now. That means that operating a STROBAR carrier for them will be a new experience as well. And like the J-15 the MiG-29K is a untested platform when it comes to carrier ops. That plane doesn't have any sort of track record on the sea except what the Mikoyan test pilots have performed on the Vikramaditya and the Admiral Gorshkov. On top of that the unique layout of the Vikramaditya will mean that the Indians will have to develop a whole new set of procedures for working the flight deck and the hangar deck below that's unique to the Vikramaditya. And that's going to take some time. The Indians just like the the Chinese in part will have to make it up as they go along.

what is it doing??

a total guess: testing some sort of marker smoke system which might be useful in situations where other communications and navigation systems are not working and approach to the carrier needs to be done not only manually but blindly. Don't know how often such a situation might arise, though...

Oh, the Liaoning is simply performing a very common naval exercise there.

The acronym for it is BSOOIA.

Blowing Smoke Out Of It's A... err, back side.

In this case it's BRSOOIA. (Red Smoke)

My guess is preparing to put on a show for some kind of fleet review or parade, possibly in anticipation of fesitivities around the next Chinese lunar new year?

I can see no other application for a modern warship laying down a smoke screen, especially one that is red.

my guess is the color smoke is used to study wake turbulence. kinda like in a wind tunnel.

thats what i would be guessing. but i'm no naval expert
