WHY don't we make a fun poll whether the 003 is CVN / CV, poll closed after some time before thing becomes too obvious and remove all the guessing funs.

The 003: Nuke Or Conventional ???


I hv been wondering why Dalian has not yet engaged in any new carrier building after Shandong?

Any idea?
Hopefully it will be nuclear powered ... having made the leap to EM catapults, why not just take it one step further and also make it nuclear powered? There are no real technical or resource limitations stopping its way.

2020 July is the submission date for tender document of the new boiler test facility on Zongming island Tender result will be known ?? months later. Contract to be signed thereafter, this will be around end of 2020. Contract duration stipulated is 38 months, so the project will be handed over to JNCX shipyard at end of 2023 or early 2024.

After hand-over, there will be pilot test runs of equipment intended for familiarization by the engineers and technicians from JNCX shipyard. By the time the facility is ready to go for real thing, it is already middle of 2024.

So this facility seem more likely is built for aircraft carrier 004 instead of 003. 003 is expected to be launched middle of next year (2021), complete its outfitting in 2022, and sea trial by 2023 and enter PLAN service at end 2023 or early 2024.

So the timeline does not match.

If 004 commence steel cutting this year, in 2 years time it will be in dry dock for assembly of hull modules ( year 2023/2024), it will get its boiler tests completed in time for installation, before 004's hull housing power plant is sealed and join with other hull modules. Thus more likely this facility is for CV004.

Whether 003 is or is not nuclear powered is another matter. 003 is expecting to have its power plant hull module seal and join with other hull modules before end of this year.
It may be for 004, but the bidding procedure could be just for something already in processing or even finished. That's not rare for many government purchases in China. Anyway, if 003 is not nuke powered, 004 must be!

so this satalite image of the drydock is like.. totally new right? and by saying "new" I don't mean the date it was taken in but I mean we have never seen this particular image before now right?
His numbers aren't exactly accurate, since the CV-17 is not 315 meters long, but 305 meters, same as the CV-16.

38 months after means May 2023, as they started the purchase of equipment since March 2020.

But the sea trial of May 2023 is also too early for the Type 004, and let's assume the Type 003 will be launched in the summer 2021, maybe it will take another 1.5-2 years for fitting out.

It took 13 months for the CV-17, but the amount of work for the CVN-18 will be completely in another league. Therefore it will take much longer.

The Type 003 is most likely a supercarrier that weighs over 90,000 tonnes.

What type of super powerful boilers are you going to use for this monster?

If it weighs 70,000 tonnes, then it is going to be conventional for sure.

But right now even the most conservative guy in the CD forum cannot deny that this ship is significantly larger than the Kitty Hawk class.

And the Kitty Hawk class already used some much more powerful boilers than both Type 001 & 002.

You would be surprised how many people still think this carrier will only be the size of that of the Kitty Hawk :hitwall: :disagree:

Because most people don't want to learn more about this ship, and their mind has already been preoccupied by the early online rumors.

I said it depends the block coefficient of the ship.

If it is a relatively slim ship with low Cb, it is going to weigh over 90,000 tonnes like the Nimitz class.

If it is a relatively fat ship with high Cb, it is going to weigh over 100,000 tonnes like the Ford class.

Here's a clear and simple explanation of what's the Cb.

Block Coefficient (Cb)

The block coefficient of a ship at any particular draft is the ratio of the volume of displacement at that draft to the volume of a rectangular block having the same overall length, breadth, and depth.

In the figure below, the shaded portion represents the volume of the ship’s displacement at the draft concerned, enclosed in a rectangular block having the same overall length, breadth, and depth.

Block Coefficient (Cb) = Volume of displacement ÷ Volume of the block

Block Coefficient (Cb) = Volume of displacement ÷ ( L x B x draft)


Volume of displacement = L x B x draft x Cb
= therefore

Example

Question: A ship 64 meters long, 10 meters maximum beam, has a light draft of 1.5 meters and a load draft of 4 meters. The block coefficient of fineness is 0.600 at the light draft and 0.750 at the load draft. Find the deadweight.

Answer:


Light displacement = L x B x draft x Cb

= 64 x 10 x 1.5 x 0.600
= 576 cubic meters

Load displacement = L x B x draft x Cb
= 64 x 10 x 4 x 0.750

= 1920 cubic meters

What is draft?

The draft (AmE) or draught (BrE) of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel), with the thickness of the hull included; in the case of not being included the draft outline would be obtained. Draft determines the minimum depth of water a ship or boat can safely navigate.

The Cb of the aircraft carrier is usually around 0.6 at full load.

CVN-68: 88000 / 317 / 40.8 / 12 = 0.567

CVN-78: 101600 / 317 / 40.8 / 12.5 = 0.628

They will never leak the true superstructure of the Type 003.

This is the superstructure of the original Type 002.
If it is indeed nuclear power, the superstructure size and appearance will look heavily different to that of the 002. If it is still conventionally powered, then most likely we are going to get a downsized 002 superstructure (i.e. reduced by 25%).
