CV-18 Fujian/003 CATOBAR carrier thread

[drunkmunky]

Can someone compare the progress with the '17' to see how different the chassis is?

Except there clearly is, the bigger your carrier is the slower and less flexible it becomes.

Clearly how? Speed is primarily a matter of propulsion choices. And you will find the largest carrier have the highest top speed, that is an engineering and operational choice more than anything else.

Furthermore with carriers how is a smaller hull more flexible? If anything, it is less flexible, because more focused on particular mission specs in loadout, ordnance reserves, fuel reserves etc. That is the primary driver for all carrier operators wanting more, not less displacement.

PS: Sorry to admins, if this is now going sorta OT. I will just leave it at that, as long as it doesnt go straight back to Type 003. FWIW.

You have 1 big carrier, it can only be at one place at a time. If it ever goes into maintenance then you have nothing. If you have 2 smaller carriers they can be at different areas, and you can rotate them on duty.

If there is no such thing as a carrier that is too big why isn't the US building 250000 ton carriers and sticking to ~100000 tons with Ford-class

Not necessarily true for speed. The bigger a ship gets, the less horsepower per ton it needs to get to the same speed. An Arleigh Burke has 100k hp, a Nimitz has 260k hp, and they have similar speeds.

That's surprising, I didn't know that.

Here you go. ( 002 is 11/2015 and 003 is 10/2020)

Thanks and a good comparison. So roughly 1 1/2 years before launch of 002.

Shandong is a follow-up ship, Type 003 is a new design. With a new design, interruptions for reorientation in the construction process are more likely than with a replica.

Are those gas turbine /gearbox assys?

The biggest marine gas turbine is 36MW, even two is too small for this big ship.

 

[Tam]

Should use four turbines at least.

That looks like COGAD - Combine (1X) Gas Turbine and (2X) Diesel engines propulsion. Gear box coupling is in the middle.

Sorry, that is just example, the question is : what is in the 003 belly? COGAD similar like this ?
Horizontal lines are the diesel/gas turbined, vertical is the gearbox ?
