may be, your talking about 003 sister ship here - but this ist not 003 sister ship. also this ist not a carrier - it could be the supposed nuclear icebreager
you are confused between Jiangnan and Dalian shipyards..

003 sister ship will build in Jiangnan shipyard. and that Nuclear ships program also initiated by JN shipyard for civilian ships. like Floating nuclear powerplant and icebreaker.

there is no solid reason not to purse dual AC construction strategy.. glad government has taken the right decision.

when you accounts 50+ percent global shipbuilding capacity and abundance of skilled workforce. go for it once you master the specific technology.

Given the relative difference in shipbuilding capacity (>200x difference in civilian shipbuilding), I'm surprised at even just 2 concurrent aircraft carriers being in construction.

In theory, China could produce many more ACs concurrently. I personally believe the reason they're not doing that is because its still in the "advancement" phase of military development rather than the "bulk-up", in that each new design that rolls off the manufacturing line is partly a finished product and partly a demonstrator for new technologies. Once the PLA has settled on a mature design, then they can start mass-producing clones.

If the rumours are solid, then we're looking at the dual construction of a novel CVN as Type-005 with an improved (but still different) Fujian that would actually be a Type-004 to Fujian's Type-003 in the same way Shandong was Type-002 to Liaoning's Type-001. Then once the designs are finalised, they'll mass produce identical copies of the Type-004 CV (likely for homeland defense) and Type-005 CVN (for global power projection) at a rate of perhaps 4 ACs concurrently, if not more (depending on how much they want to ramp this up).

China doesn't have infinite money, but the actual industrial capacity is already there. The technology is lagging behind the industry.

Of course, this is all speculation. Only time will tell.

A blogger claims that he found JN's tender information on 003A, so 004 will be conventional power. But He refused to post screenshots for confidentiality

I remember the Guancha trio also said one conventional in the south and one nuclear-powered ship in the north?

another reason is, trained sailors and Pilots for AC operation. this is where PLAN currently lacking. the pace of advancement is so fast. but this dual carrier construction news is encouraging. Of course, this is all speculation. only time will tell.

IMO, my guess is that the new carrier is likely going to be gas turbine IEP with 4 QC500s and 4*20MW diesel generators for around 280MW total peak output and be slightly larger than Type 003 at ~90,000 tons full displacement. Should still be considerable cheaper than Type 004 due to using common powerplants with next gen CG/055 replacement while providing much better upgradability and sortie rate than Type 003.

It might be possible that PLAN is going with a hi-low mix for carriers as well, Type 004 being the flagship carrier type for global power projection and far sea duty but only ~6-8 will be built while JN's new ship will be smaller at 90kt and uses conventional propulsion for region power projection and fast response but can be built in large numbers quickly and cheaply(>10 total).

If the carrier is IEP, wouldn't it be better to remove 2 of the 20MW diesels and replace them with a single gas turbine instead?

You can still have the same power generation combinations, given that diesel generators can operate efficiently at many power levels, compared to gas turbines.

That should cost less and take less space etc.

GT powered CV is a complete redesign and requires 2 stacks (like 076 or QEC), reducing deck space. Fujian+ requires little additional design work and less trails time than a wholly new first of class. I don't rule out a new GT-powered design, perhaps based on 076, I just think an improved Fujian would be cheaper, quicker and in some ways better.

My understanding is that Fujian was designed for steam catapults originally, which has meant the deck is too small for the EM catapults.

So they would want to redesign for a conventional carrier anyway, and also get rid of the steam catapult spaces

A GT-IFEP/CODLAG Nimitz-analogous would be the dream. I don't want to see another Forrestal-class built in the 2020/30s.
