00X/004 future nuclear CATOBAR carrier thread

How often are ships built bow-first out the dry dock?

The preference depends on launching methods. Type 075 floated out of drydock bow first.

However, if you launch a ship using slipway instead of a drydock, stern first is the preference for a few practical reasons like control entry into the water, space constrain contol, momentum of ship during launching due to gravity and the structural strenght of stern etc. I can give some reasons from deepseek but I found quite a few members tend to get angry with others who are using AI replies. So you can do the search yourself.

In a drydock, you will just have to float the ship out and thus it doen't matter if you move the ship out bow first or stern first.

Ask this question if you want to do a search online - "Why there is no such constrain for launching from slipway, for floating a ship out of drydock?"

Another main reason for launching a ship stern first is the tradition since hundreds of years ago, which is related to Christians. Since they have to bless the ship, christening it a name, and break a bottle of champagne for good luck. And the tradition way is to do it on the bow of the ship.

But then China is not a Christian country...

I don't recall this being posted before, but here's a bidding announcement (from 2020) made by the Nuclear Power Institute on a verification module for impact resistance of marine nuclear reactors against underwater explosions.

An aerial update from Dalian on whatever it will become ... I still don't see this as an aircraft carrier, but at least some larger parts are clearly visible now!

At this low speed for a commercial vessel construction, Dalian would lose big bucks. It still don't look like a 004 to me as well.

wow, dual reactors

Obviously we can't say for sure that it's a carrier, but at this point it I feel like we have more reasons to think that it is than it isn't.

Reasons for:
1) slow speed of construction
2) size
3) timing lines up with reactor tenders and rumored modules

Reasons against:
1) ...

I honestly can't even think of a reason against. It's likely military due to point #1, and its size indicates a very, very large ship so almost certainly a carrier. Now that we've established that there's no particular reason that China needs to float a ship out of the drydock stern first, I just don't see how carrier isn't by far the most likely answer.

It could be another 076.

...

Well, there are several ...

1. seems as if it is facing in the wrong direction (stern on the left)
2. seems to be split into two large parts / halves
3. the bollards on the bottom contradict a slim / high-speed design
4. why not again prefabricated modules like 003?

and against your plus-arguments:

1. the speed of construction could be (even if unusual) due to other reasons!
2. could be a large LNG tanker, so size alone is not an argument.

Whether or not to use prefabricated modules depends on the shipyard. The one in jiangnan prefers prefabrication but this one does not.
