Interesting thread by @horobeyo. Looks like same VLS as 054, maybe 100mm gun and larger helo deck for Z20F.

Hopefully this news means that these vessels will still be low cost and they will be able to make a lot of them. These are going to be excellent at ASW against the US underwater threat, I hope there are more of these that the A version, and I also hope they can be exported because the ability to run silently is exactly what is needed to deal with the US submarine threat for all countries.

Addition.

Listing details regarding 054B from the thread and related comments, as follows:

1. Displacement (at full load): Estimated ~6000 tons.

2. Length (once completed): Estimated ~150 meters, i.e. larger than 054A (134 meters)

3. Beam (at the broken line(?)/amidships(?)): ~18.66-19.08 meters, i.e. larger than 054A (~16.0 meters) and the 052D/DL (~18.0 meters)

4. Beam (at stern): ~16.32 meters, i.e. larger than 054A (14.55 meters) and 052DL (15.78-15.84 meters)

5. Length of flight deck: ~25.87 meters, i.e. larger than 054A (21.59 meters) and 052DL (25.01 meters), almost similar to 055 (25.52 meters)

6. Vertical launch system well: ~7.55 meters long x ~5.86 meters wide, i.e. roughly similar to 054A.
6a. Expected to be using the same H/AKJ-16 VLS to carry HHQ-16s.
6b. There is the possibility for the H/AKJ-16 VLS cells to have greater depth than those on 054A, hence able to fit advanced variant(s) of the HHQ-16 that are longer, hence longer range(s).
6c. The UVLS from 052D and 055 can be excluded (a 32-cell UVLS grouping is 8.4 meters long x 5.3 meters wide).

7. (Main) naval gun pit: ~2.94-3.01 meters long x ~4.77-4.94 meters wide.
7a. In contrast, the size of the 054A's Type PJ-26 76mm main gun pit is ~3.01 meters long x ~3.67 meters wide.
7b. Two possibilities - #1: The same 76mm naval gun, or #2: Previously rumored new 100mm naval gun?
7c. If possibility #1 is true: Having a wider pit width, which is presumed to increase the amount of 76mm naval gun ammunition carried by the magazine because there is more space in the ship; or
7d. If possibility #2 is true: The new 100mm naval gun may have amazing volume control and can fit into such a compact space.

Continuation thread on the 054B by @horobeyo on Twitter.

(Roughly translated text from his thread are in the quoted form.)

Comparison between 054B and 054A:
The above image can be considered as the bottom/waterline profile of 054B.
The middle image is the state of 054B on March 9 this year. You can see that the diesel engine compartment (presumably) has been sealed.
The bottom are images of the final assembly of two 054A ships with different construction progress in the dock in the past, with the equivalent photographing height set at 140 meters.

Because the firepower configuration of the 054B has no qualitative change compared with the 054A with a full-load displacement of 3,900 tons, the original intention of developing the 054B is (actually) to upgrade and verify power, perceptual ability, speed, and ocean-going seaworthiness.
My (@horobeyo's) personal speculation - 054B will adopt an all-electric integrated propulsion system.
The diesel engine is the most forward and located amidships with multirole capability as a ballast, because the diesel engine intake and exhaust arrangement is less restrictive.
Therefore, the (diesel engine) exhaust pipe can be extended to the rear, which can be integrated with the gas turbine exhaust pipe into one chimney.
My (@horobeyo's) personal speculation - The power composition is to have two 25MW CGT-25-D gas turbines for power generation + two 6MW diesel generator sets, with a combined power generation of 62MW and a propulsion power of 40MW.
Or, a single 40MW class CGT40IC intercooled gas turbine + two 6MW diesel generator sets, with a combined generating power of 52MW and a propulsion power of 40MW.
Compared with 054A's four sets of 16PA6V-280STC all-diesel (propulsion system) with a total propulsion power of 20.72MW, it can be described as a qualitative leap.
Of course, I (@horobeyo) am not responsible if my guessing is eventually proven to be wrong.

So, if we go by the above estimates, an increase in displacement from 4000 tons on 054A to 6000 tons on 054B while retaining essentially the same weapon suite. Where would the displacement go - IEPS? More fuel and stores? Anything else?
Essentially, (likely to be) yes.

Basically, you got a 054A-repeat - But much better.

would love it, like DDG167 Shenzhen with 16 YJ-12 anti-ship missiles, huge upgrade from 054A with 2 × 4 YJ-83 anti-ship missiles
Frankly I am thinking it would be better to retain the YJ-83s on the frigates instead for closer range fights and ambushes around the Philippines and Straits of Malacca.

Related (also a minor correction):
7. (Main) naval gun pit: ~2.94-3.01 meters long x ~4.77-4.94 meters wide.
7a. In contrast, the size of the 054A's Type H/PJ-26 76mm main gun pit is ~3.01 meters long x ~3.67 meters wide.
7b. Two possibilities - #1: The same 76mm naval gun, or #2: Previously rumored new 100mm naval gun?
7c. If possibility #1 is true: Having a wider pit width, which is presumed to increase the amount of 76mm naval gun ammunition carried by the magazine because there is more space in the ship; or
7d. If possibility #2 is true: The new 100mm naval gun may have amazing volume control and can fit into such a compact space.

By comparing the hulls of 054B and CCG variant of the 054A, @horobeyo found that the naval gun pits on both hulls have (nearly) identical dimensions. He deducted that the 054B is expected to still be using the H/PJ-26 76mm naval gun, i.e. similar to the ones on the 054A. It is expected that there would be no difference in the amount of ammunition in the magazine for the gun itself as well.

Here are the two hulls taken at an equivalent height of 140 meters, with 054B above and CCG 054A below.
