China’s Submarine Fleet, Evolution & news

[FuturePAF]

Around 2025 we should see something. Right now they're building 093B.

How many SSNs per year do you think they will build? The Huludao facility has been recently expanded to have the floor space to build 20 subs at a time.

With a build, fitting out, and commissioning time of 5 years in other navies (per subs like the RN’s astute SSN), taking into account downtime between ship classes, is an eventually SSN fleet of 48-50 SSN and 12-16 SSBN (basically parity with the USN) within 15-20 years likely?

This in addition to the 50 SSK numbers they are probably going to maintain, they would be at parity with the USN, Japanese navy and South Korean Navy submarine fleets combined.

I think they will start construction for at least 2 per year, but the first 095 will take longer.

Seems to be equal to the desired rate for the Virginia class SSN in the USN, currently the rate is 1.2 SSN/year for the Virginia. So with 6-9 SSN, they will achieve the 50 threshold in at least 20-22 years, but taking into account the slow downs between ship classes; by 2049 is a realistic date.

I actually don't think it's a great idea to mass produce SSN before Taiwan is reunited. SSNs excel at deep ocean operations due to their speed and diving depth. If you look at the primary areas of activity for PLAN, they're mostly shallow water environments near the Chinese coast or South China Sea. It's best to produce advance SSK with AIP with limited number of SSN.

Once Taiwan is taken, doorway to the Pacific would be open. China could build a submarine base on eastern side of the island and focus on SSN development from there.

They are building both, and plan to use both in any Taiwan scenario. If a fight happens. It will be in shallow and deep water, in the straits and beyond them.

I agree. That's what I've been saying. Yet, with the development of far-reaching carrier strike groups, the development of SSNs needs to be accelerated.

Pump jet? VLS tubes?

Btw, the Type 054B/57 looks like it’s under construction. So this isn’t the only satellite imagery coming out in recent days. This ship will probably be a lot better for ASW. So we will probably see many exercises between the Type 054B and the Type 093 in the coming years.

China's Type 054B Next-Gen Frigate Under Construction? - Naval News

A new warship hull widely assumed to be the Type 054B next generation frigate for the Chinese Navy (PLAN) has commenced final assembly at Hudong Shipyard in Shanghai.

Its indeed a lot larger than 054A and street said it has IPS, we will see.

Said to be able to keep up with a carrier battle group and be quiet enough that it can use its towed array at cruising speeds.

By now all Chinese subs be fitted with rim propeller and no longer shaft driven prop.

Ultra quiet, the better to hear the Murican subs and naval assets.

VERY VERY WORRIED

China's new submarine engine is poised to revolutionize underwater warfare

A Chinese admiral reveals that China has mastered a new and silent electrical propulsion system for submarines.

www.popsci.com

A rim-driven pumpjet has a ring-shaped electrical motor inside the pumpjet shroud, which turns the vane rotor (a vane rotor has the fan blades attached to a rotating band built on a cylinder interior, as opposed to a propeller shaft) inside the pumpjet cavity to create thrust. Previous submarine pumpjets are “shrouded propellers,” which consist of a tubular nozzle covering the propeller. By removing the shaft of the propeller, the reduction in the number of moving parts decreases the noise made by the pumpjet, as well as saving hull space. Civilian manufacturers also claim that rim driven pumpjets are easier to maintain, and have less cavitation (bubbles that form during propeller movement), making them even more quiet.

America will find a way to detect them, a network of unmanned drones with towed arrays will be searching the seas. But rim drives will make the job harder for sure.
