Re: Chinese sub thread
Why would China build so many SSBN's? I've seen numerous Chinese articles that commenting on how the US nuclear arsenal and nuclear powered ships are unsustainable because it's extremely expensive to decommission them and dispose of the nuclear waste, and it has already became a serious budgetary problem in the US. So why would China build so many nuclear powered ships all of a sudden?
One should add that the Russians have 26 SSBNs by the year 2000, for a total of 440 missiles with about 2,272 warheads, more than half of their arsenal.
And yes it is extremely expensive to dispose of nuclear ships and submarines, which is why even the US, Canada and Japan have to financially sponsor the dismantling of old Soviet nuclear subs. That pace is still rather going on slowly because its not even cheap for the sponsors. A lot of Soviet nuclear subs are decommissioned but they are still mostly lying around the docks.
As for disposing of waste, waste is often recycled instead into stuff like depleted uranium. One of the reasons why DU is used in ammunition and tank armor is economy, the US has so much of it and Tungsten is very expensive---because China is the dominant source of Tungsten in the world (over 75%) and wasn't exporting during the hard core Mao times.
Nonetheless, you can see the huge value of nuclear submarines---the US has over 56 LA class alone. The Russians decommissioned at least 130 nuclear subs which gives you some idea what they had during the Cold War. It will take a long long time before China reaches to that point with her pace of production.
Why build nuclear powered ships all of sudden? That's because the PLAN is transitioning from a brown water to a blue water fleet. That means it is not longer myopically shackled to a Taiwan liberation mission. No matter how Japan likes to pretend with its conventionals, they simply cannot keep up with the range, speed and endurance of a blue water fleet. That's what a nuclear sub can do best, keep up and act as a fleet submarine. If you have a Chinese CVBG, and you want some protection underneath, you would want a Shang rather than a Song.
As for SSBNs, beats me. Its a surprise for me to see even three SSBNs because I am not sure how SSBN fits into a Chinese nuclear deterrent strategy. It seems to me that mobile DF-31 and -31A can provide a mobile and hard to catch nuclear deterrent. These located in northern China, have a better chance of ranging over the northern hemisphere than SSBNs in the Bohai sea. It is very difficult for SSBNs to break out into the Pacific because of the natural impediment of the Japanese islands from Tsushima/Dokdo acting like a guard to the Sea of Japan, to the Ryukus acting like a picket fence to the Pacfic from the East China sea. It may also be because China still respects and fears nuclear powers like Russia, as well as rising ones like India.
