PLAN Aircraft Carrier programme...(Closed)

中国海军的核动力发展，肯定要追溯到第一艘核动力攻击潜艇。现在有关中国建造核潜艇的书籍和刊物已经比较多了，逐渐把笼罩在核潜艇研制上的大幕徐徐拉开。但有关中国第一种核潜艇的一些关键性指标，例如核动力装置的功率，依然极少。2001年《兵器知识》杂志刊登了美国斯坦福大学教授约翰·威尔逊·刘易斯的《中国建造核潜艇》一书的部分内容，其中提到中国核动力攻击潜艇的压水堆功率为48 MW，而核动力弹道导弹潜艇的压水堆功率为58 MW。而中国科学院高能物理研究所研究员沈经在2008年发表的文章则透露中国首艘潜艇核动力装置的功率为90MW。两者相差了几乎一倍。但不得不承认的是，无论是48还是90，这个数值和国外相比还是有相当差距的。美国从洛杉矶级核潜艇之后的潜艇用核反应堆功率一般在150MW以上
little information regarding the development of Chinese naval reactor,but info about the Chinese nuclear reactor for submarine beginning emerge,for example Stanford uni. professor William louis book claim that PLAN nuclear heavy water nuke reactor for first.gen. attack sub has 48mw output.while SSBN carry 58MW reactor..but a 2008 scientific report prepare by Chinese research lab Chinese nuclear submarine power by a 90mw nuclear reactor.but no matter if it's a 48 or 90mw output,still way behind the Los Angeles class SSN,which has 150MW output nuclear reactor.
if PLAN do plan to construct a nuclear power carrier,there are lot of technical huddle to overcome.

Yup.. Build another Lioaning like ship followed by a couple of CVs and then CVNs but I'll be an old man by the time PLAN's first indegenous CVN commissions so I don't really care.

Well, I know how you feel. I am 57 years old now, so if we project...

1st indegenous starts building now, finished in 4 years, commissioned two years later. So I am 63 then.

2nd and 3rd indegenous carriers, convetnional. One starts in 2016 finished in 2020, commissioned in 2022, the 2nd a couple of years behind it so in 2024, it commissions. I am 68 years old then.

Whew. Now lets say they start a nuclear carrier in 2026, it takes six years to build (new stuff, harder to do, 1st time thing), and then two more years to commission, so it commissions in 2034, now I am 78 years old...if I am still kicking then. I just might live to see it. At that point, China will have just produced their fifth carrier.

Of course by then, the US will have produced the Jonh F. Kennedy, CVN-79, the Enterprise, CVN-80, and two others, CVN-81, and CVN-82 so that by that date there are five Ford Class carriers, and the remaining six Nimitz class still in service.

Lot's of water will have passed under the bridge by then. Who knows what the world will be like?

...wer're talking 21 years from now.

Kind of make sense for Shanghai to attempt the smaller LHD first if they are building a new cat carrier from scratch. Plus 40k+ tons is not that small. Dalian will probably aim to push out a Liaoning similar ski jump carrier. I hope they shrink the island significantly.

A naval propulsion reactor using heavy water? I think that would be the first in the world. It would reduce the amount of neutrons absorbed by the moderator so reduce the amount of uranium enrichment necessary but would it worth while?

In regards to the length concern with the carrier elevators. If the J-31 was to be the PLAN carrier fighter it would fit comfortably into the elevators right? Considering J-15 is ~22m in length it barely fits onto the elevator, and J-31 estimated length is ~17m. That's plenty of room for J-31 to operate on the Liaoning.

Since the J-15 is very large, it was estimated by this forum that maximum of only 30 could be fit into the carrier. If it was to say be equipped with J-31 wouldn't that squeeze a few more in since its significantly smaller?
