00X/004 future nuclear CATOBAR carrier thread

New excerpts from academic paper by SOYO on Weibo, decribing a ship with a listed length between perpendiculars (LBP) of 300 meters, (waterline) beam of 40 meters and draft of 10 meters.

According to SOYO, If the length between perpendiculars in this academic paper document is correctly listed, it would mean that the elongated variant's design model for the Type 003 CV does exist in reality, and its emergence was quite early.

A waterline/LBP(?) length of 300 meters and a beam of 40 meters give a length-to-beam ratio of 7.5, which is still smaller than that of the Kitty Hawk and Nimitz classes. However, the waterline length is at least 6 meters longer than that of the current Type 003. Correspondingly, the flight deck could be extended by at least 4 meters beyond the Type 003 CV's, reaching a length which is comparable to the Kitty Hawk-class CVs, i.e. around the 320-meter mark.

TL; DR - If the sister ship to Fujian (i.e. 003A CV) does actually exist, then this 003A CV could be slightly longer than her sister ship, and become an almost equivalent to the Kitty Hawk CVs in terms of overall dimension.

It makes perfect sense, a few more meters in length, another meter of beam, alongside various smaller mods one would expect from an improved 003A. Question is will they add another cat or another elevator? Which would it need most? I would say another elevator to speed up aircraft movement, but that's just me.

First of all, you overestimate the geopolitical relevance of six carrier battle groups in isolation.

Second of all, your prior post was vastly off topic and is just nationalistic chest thumping without any substance. I advise you to drop it.
Exactly. You also needs to have troops stationed there, every politician compromised through mass surveilence, and also allow enough grifts to make them stay loyal, and create an organisation like EU to make puppet work against each other for you. The art of neo imperialism goes far beyond just brute force.

A question, some months ago a similar hull study excerpt as we just saw for possibly the 003A was posted of likely the 004, but i can't find it now, from memory the waterline length was 310 meters and width 41 meters (compared to 300x 40 for 003A), is that correct? Could anyone repost that by any chance?

PS: Found it, it was 315x 42 meters, and estimated at 110,000 tons.

This is not an unreasonable depiction of CV-19 and CVN-20 configurations, per 大包

CV-19 of course here is being depicted as a 003-mod, which as previously mentioned, would be reasonable if they do not intend to pursue further conventionally powered carriers after it and go nuclear only.

The island between CV-19 and CVN-20 show the way their islands share the common main section while CV-19 has a rear connected smoke stack.

I only see 2 elevators on the starboard side of the 20. Perhaps they think the elevator aft of the island isn't worth it and will in turn make the other 2 bigger.

I fear that people are hyping up the estimated size far too much. The Drydock at Dalian is only roughly 366m long
really? I thought it was much larger, albeit from a rough estimate just based off of the scale on google maps.

What that needs to be, I have no idea. What I do know is at least during the Fujian's construction, that distance was around 20m on both ends. Does that mean the 004 is capped at 326m long? No. But I just wanted to point this issue out to those convinced it may be a 340-350m long monster.
It's for the waterline length, the flight deck is overhanged. Nimitz class's WL line is only 317m with around 16m of overhang. If 004 do indeed max out at over 320m WL than it's definitely possible for a 340m+ flight deck.

There is actually one more elevator at the port side of CVN-20, as denoted by the caution stripes outlining the elevator deck.

In fact, the 3D model of the CVN-20 made by Big Bun CG is actually largely inspired by the Ford CVNs.

2 elevators on the starboard side of the "CVN-20" with a very aft island (and 1 elevator on the port side next to the waist) is the same overall configuration as Ford class.

340m Flight deck is possible but that would need the ship to squeeze into the drydock with a much lower end to end separation distance than what the Fujian had, a 35% reduction. Using previous satellite imagery, I've made this graphic below. I would put 340m as the maximum possible extent as separation distances below 10m seems highly unlikely.

I wouldn't necessarily take "spacing between drydock" to be an expected, consistent measure when the sample size is so small.

For example, prior to CV-18, the CV-17 built at Dalian had spacing that was 30m from the bow-most part of the ship to the drydock wall, and nearly 20m at the aftmost part of the ship

Given they're going to be building larger ships in the same drydock, it's more reasonable to surmise that the positioning/spacing of existing ships built so far are simply "under"-sized for what the drydock is able to maximally accommodate.

and if we look at the construction of USN CVNs (in this case a Ford class, USS JFK I believe), they barely have a few meters between the aft flight deck section and the wall of the drydock (the length of the dock means the bow spacing is not a factor), so a spacing of some 10-15m either side seems eminently reasonable.

(That said, I don't really have a horse in the race as to what the actual expected length of DL's carrier will be)
