Think we're in agreement on the SSN side. More SSNs are needed. 50+ SSNs should be the goal.
as
@sunnymaxi has stated , the batch of 8 type 093B boats is a good start!
On the SSBN side we differ a bit , the PRC should end(STOP!) the production run of the type 094 boats at six as place holders for the JL3s. When the type 096 boats come online convert all six type 094 boats into SSGNs armed with a sub launched variant of the YJ-21 or a "HyperSonic Anti-Ship" missile type. (example canceled Project 667M "Yankee" SSGN)
Now if the PLAN opted to build a clean sheet "Project 949A SSGN type boat" out right. Then convert 2-3 of the type 094 boats into "mother droneships/ UUV carriers" and scrap(decommissions) the rest. Mothball the type 092 to a museum if still around.
The Royals(who gave up on their bomber force decades ago) and the French(who have a few tactical nukes left) operate just 4 SSBN each as their main or only nuclear platforms. Both fleets are more then enough(capable) to get the point(message) across. So the PLAN SSBN fleet should stand at 6(type 094) boats until the new class(type 096) replaces those 6. The USN current SSBN fleet stands at just 14 boats plus 1 new class building. Their end goal is to replace all their old boats with this new class minus(short) 2 , giving them 12 total by the 2050s.
6 SSBN boats plus JL3s is a good number/mix. Any more is just wasteful spending and that could be better used on a offensive frontline platform with more flexibility , like more type 093Bs , 095s , 095As etc.
Also US geography/doctrine drastically differs from the PRC. The US is a two sided coastal state with bases all over the world with vast access to deep waters. On other hand (until reunification "2040") the PLAN lacks the basing and access to deep waters where they could send out a type 094 boat on patrol "cleanly" on a continue basis. The US is about world power projection and is a "first use" state. Their false doctrine is still rooted in "cold war" thinking , which dictates that an "X" number of SSBNs is required for nuclear deterrent in today's world where they No longer have the large advantage they once enjoyed on multiple fronts. There's a lot of "grey" and less black and white. The Paradigm has shifted.
Again this is just my opinion in respect to yours.
