That can't be right! The island is too far stern and would significantly decrease the landing angle on approach for emergency maneuvers. The island size is also too big relative to its overall length.
You usually want to place the island on the widest part of the ship.

Won’t you guys realize it’s clearly not placed at the very end of the ship. The building cannot be extended in length which is why it appears to be at the very far back of the flight deck, the building has not been extended since shandong. So this is not the clear dimensions of the 004.

This picture shows how it is meant to look (compared with Ford at the bottom). The mockup is not the full length of the ship -- a large part of the aft flight deck/overall length is "cut out" because the mockup (sized for CV-16/17 originally) was not extended for the new, larger ship it is meant to be simulating.

Gotcha . Well in that case it's certainly more plausible! However the island appears to include the stack. Of course it's grainy and hard to speculate at this point.
Do we know with certainty 004 will be nuclear powered? Or is that also speculation? Could still be Fujian's bigger sister ship.

Unless the 004 turns out to be 600m long and the island is in fact in the middle of the ship. There is no possibility that the 004 is conventionally powered. The ducts for the exhausts cannot be bent to such a degree. Engine rooms on ships are always in the middle of the ship, which is why all conventionally powered ships have a middle island. Its not speculation, this is basics to the engineering and design of a ship.

I'm NGL but it seems that the mock up of the 004 is slightly wider than the ford? Possibly that 004 will be slightly larger than the Ford, some dude on weibo in Captain's comment section was saying 85m beam

Not for diesel powered ships.

Not for diesel powered ships.

And yet we don't have aircraft carriers that are majorly, let alone fully powered by diesel engines.

As a matter of fact, there are no diesel engines that can rival gas turbine engines (and steam turbine engines as well) in terms of power-to-weight ratio and operational flexibility. Both factors are absolutely important factors for warships with volume and displacement constrains.

This hasn't yet include all the other additional considerations for proper major warships:
- Reduced vulnerability to battle damage (allowing more compartmentalization and greater degree of damage control capabilities)
- Better weight distribution and stability (which is crucial for aggressive maneuvering at higher speeds during combat scenarios)
- Better noise isolation (important for ASW-focused warships e.g. DDGs and FFGs)
- Hull form optimizations (propulsion systems are bulky, and major warships need finer-designed hulls for greater speed and maneuverability)
etc.

In fact, in contrast to commercial/civilian-grade/operated ships - No major proper warships have their propulsion and power generation systems placed anywhere besides amidships.

Nothing significantly new in the latest satellite picture.

If that were 1 ship, how long would it be (both with and without the section where there appears to be a gap in the keel blocks)?
