09III/09IV (093/094) Nuclear Submarine Thread

Maybe that's why the PLAN's Y-8 ASW constantly patrol that area.
XI is calling for war preparation regarding to taiwan.

There ought be a strong submarine force based in Shantou that can quickly cover that area guarding the entrance of SCS.

4 of 93b nuke subs and 12 of 039b/c AIP diesel subs can accomplish that task.

Xi can call for whatever he wants but his submarine construction base is still under construction/expanding and has still not started massively building the new modern subs from what I know.

So unless he has some other cards such as UUVs or other capabilities he should wait for another 5 years or so.

I thought those new sites are for 095/096. The old sites can handle 093b, no?

093A and 093B should be quite useful similar to 055. Why China doesn't crank out more numbers? That's an assassin mace weapon.

I think besides Bohai nuke powered sub building, Shanghai should also produce that similar to carrier , 055, 052D programs.

Type 039A is the better weapon for SCS. The SSNs can go further but they are noisier than 039A that drift around and most importantly stay hidden at random points. 039A are smaller and quieter than the nuclear powered ones China currently fields. The PLAN does have over a dozen AIP subs and produce them at a faster rate.

They probably also have unmanned drone subs that are tasked with attacking surface vessels.

Isn't 093b has more powerful sonar that can detect opponents's subs?

It does seems to carry more sonars . The additional side sonar and the towed array from the small hump

According to Chinese media, US carriers going through SCS is just for shows but underneath the water there were alot of confrontation between PLAN submarines and USN submarine around the water Southwest of Taiwan, near Dongsha island. It's the most strategic spot because it watching over the entrance into SCS from bashi channel between Taiwan and Philippines. Any US forces coming in will transit that area. For the past years and currently both side subs are hunting each other underneath.

Submarines showdown will be the deciding factor between PLAN and USN in SCS

093b is alot more important than 054a, 056. Overbuilding those surface ships is kind of pointless especially US cranking out alot of AshM Lasrm.

I don't think so or at least the PLAN doesn't think so. PLAN is disadvantaged going against USN sub to sub with their noisier subs, hence the best counter to that would be ASW surface vessels. This is leveraging PLAN's strength in surface ship technology and production. Remember that a sub, no matter how quiet, has no counter against active sonar. This is why the VDS is so important.

Y-8's won't be going to specific spots at a specific time unless the USN subs themselves might have been detected and the Y-8s might be performing simulated attacks against the subs.

Back from 2000 to 2012, there was a massive growth spurt in the number of PLAN submarines but since 2012, that shift to ASW vessels and there should be a strong reason behind it.

I really doubt that. The modern 039A variants are built later than 093 and both should receive the best China had available in that department during the 2010 to 2020 period. They can be removed and upgraded. Upgrading internals is more worthwhile since there are only so many submarines. It's not like having to upgrade 100+ J-11B with AESA units.

The 093 may have more and more powerful sensors owing to its propulsion, but that doesn't make 039A much less effective. They also clearly have comms and outside guidance if they can launch anti-ship missiles.

Original Type 093 have flank sonars that is the flat conformal type. Both appear as square patches in the hull. Even Han class has flank sonars refitted. The location are indicated by white bars in the hull, which is a warning to the tugs not to tug in that part of the sub.

The newer 093A has these linear flank arrays instead as you can see compared to the previous model.


Han class. Note the flank array markers in white.

039B has this long linear array at the bottom of the sub.

I am not sure if this is a TAS or a long linear flank array.


There is also a warning marker to indicate a flank sonar in this location.

There is a wake sensor on the nose too.

Surface vessels are easier targets to be killed by airstrikes.

How if 093b work in tandem with 039s?
093b provides the powerful sonar ability and 039 would be passive listeners for reflection.

Surface vessels are far easier to digital network across satellite and with aircraft, UAVs, USVs and UUVs, to share information.

The biggest improvements on the last batch of Type 056A are focused on new SATCOMs.


PLAN submarines themselves will be hunted down by surface vessels and patrol aircraft unless both are also countered by surface vessels and aircraft.
