CV-18 Fujian/003 CATOBAR carrier thread

[Blitzo]

When 004 eventually hits the water it will be interesting to see how many of the 'faults' and 'deficiencies' in the 003 design picked up by SDF members are actually resolved

There are many improvements that 003 could undergo in a successor design, but new design would also require a larger ship to enable some of those improvements to be undertaken in the first place. Not to mention the improvements that would be facilitated by the prospect of nuclear propulsion.

In the case of the placement of the catapults, as it has already been mentioned, the operation of the catapults and elevators simultaneously should not be an issue as the flight deck should operate in a cyclical manner anyhow.

There would of course be some benefit in having greater clearance between the two, but that would also require a longer ship to enable moving the catapult and the catapult launch position forward by about 10 meters or so.

Alleged new information on Fujian(??)

No idea how he calculated that 2025 handover timeframe.

should this be for type 004? I though all the turbines related equipments should be already installed for type 003.

May be 003B？

The contract is not about installation of the turbines, but covering them with insulation which doesn't have to be done before launching. I also imagine that one does not do this work before actually having the turbines running at low power to detect any possible leak. It is similar to installing radar only after launching.

Yeah insulation on turbines like acoustic insulation etc comes right at the end after the turbine has been commissioned and finished the 72 hrs test. Pretty conservative schedule of 80 days for that work haha.

Fujian went through mooring trial. Officially announced by CCTV.

I think 80 days is the lead time, not the time needed which is less.


周期 is lead time from the first day starting the work to the last day. As it is stated in the contract, the real 周期 is dependent on the installation of the turbines on the site. There are 4 HP turbines, 4 LP turbines and many other things. The insulation work may be divided in many pieces spaced by installation and testing work. The actually work of the insulation should be much shorter. In other words, the 80 days is probably closer to the whole powerplant work.

An update.

Fujian undergoes power system test and debugging. High pressure steam is piped in from onshore boilers via a specially designed steam delivery system in order to verify the ship's steam turbines and other components of her power systems. Because the ship experiences movement while moored, the steam delivery system has

The head of Fujian's Aviation support department is already a senior captain. For PLAN, Fujian will probably have the largest number of senior captains on one ship when it's commissioned.
