Currently, China has at least 10 kt of SWU production capacity per year.
Modern warhead design doesn't rely on HEU, more likely restraint by plutonium. Only tamper is made of HEU optionally.

That being said, all three Uranium Centrifuge Facilities are expanding their production lines again between 2021 and 2022. I haven't got the time to write a detailed list of them yet. :( Too busy recently.
After 2020, several core units in China's solid launch vehicle development (CASC航天科技, CASIC航天科工, CAS SPACE中科宇航) have all built new production lines for 30 rounds of 100 ton solid launch vehicles (totaling 3x30=90). That is to say, China currently has the ability to produce 100 units of LGM-118A Peacekeeper per year.
CASIC doesn't make large solid rocket by themselves any more, CAS Space doesn't have real production ability either, all of their rocket engines are contracted to CASC.

But you are correct that China is making more than 9,000 ton worth of propellant per year.

You can technically design 300-500kg class ICBM warheads with zero WGPU inputs, but they are far less efficient compared to warheads using WGPU pits. In other words, pure HEU thermonuclear bombs have way lower yield-to-weight ratio than the ones using WGPU pits in the primaries. In other words, you have inferior firepower, albeit nukes are still nukes.

At present, China's nuclear warheads are mainly uranium bombs. This is the saying among enthusiasts in the past.
CASIC has been developing its own large rocket engines.
CASC's rocket engine production capacity should be large.
China is developing a civil aerospace solid booster with a charge of 600 tons, which requires a special factory and special filling equipment. The relevant research literature on the construction of the factory area will be published in about 2018-2019. After this is done, China basically has the capability of SLS and space shuttle-level solid boosters. Using this thing to produce solid launch vehicles of less than 100 tons can greatly improve production efficiency.

What I am talking about is that there are three aerospace companies with a large state-owned enterprise background in China, each of which has proposed a new production base with an annual production capacity of 30 rounds of 100-ton solid launch vehicles. In fact, China's commercial 100-ton solid rockets are far from reaching the level of 10 rounds per year. The foreseeable future is only 10-20 rounds/year

Where has all the production capacity gone? Who are these capacities prepared for? That's a more interesting topic.

I have no idea why you have such impression because AFAIK Chinese modern warheads are T-U design and I don't even know whether China has tested uranium-core or composite-core primary in the past. But I would say Chinese warhead has a egg-shaped plutonium primary, based on thousands of journals I have read and many memorial.

I think you misinterpret what they mean by "we can produce 10 of such SD-3/ZK-1A/KZ-11s" in their statement.

CASIC has lost their production capability of large solid engine, contracting almost every subsystem to civilian companies except pouring the grain themselves.

CAS-Space only has design branch in Beijing and they contract CASC to actually make the engines.

CASC is the main producer of large solid engines with capacity of approximately 10,000 - 12,000 ton worth of propellant per year.

So potentially by launching more of this type satellite can cover more or better resolution.

Does it mean that PLA now can monitor potential enemy warship or CBG constantly from within First & second island chain ?

I think China should launch more of these satellites, perhaps the next generation can do 10 or even 5m resolution and plus multiple backup satellites for redundancy


I think what you meant is spy satellites instead of "GPS" .... just different function and purpose
At 40m resolution per pixel, it is hard to distinguish a destroyer-size ship from that perch But Carrier yes it can do close watch for certain areas basically round-the-clock rain or shine cloud or no cloud day and night because it is SAR. Add to that a constellation of this satellite China will have constant surveillance over interesting areas coupled with Ai and search algorithm It can find carrier size ships Here is an excellent video explanation of the ramification of that Geosynchronous "remote controlled satellite for agriculture" using China jargon

Binkov Our latest video talks about China's high-orbit radar imaging satellite. Why is it unique in the world? How might its capabilities help China?

I haven't paid particular attention to the design details of Chinese nuclear warheads. I will pay attention in the future.
Regarding the types of Chinese nuclear warheads, Chinese military enthusiasts rarely discuss in detail. I only know, and generally believe that
China mainly uses uranium warheads instead of plutonium warheads.
You cannot understand the operation of CASC and CASIC according to the operation of large Western military enterprises.
Enterprises are national, and the senior leaders of CASC and CASIC are regularly partially rotated. Yes, the executives of CASC were transferred to CASIC to lead the work, and the executives of CASIC were transferred to CASC to lead the work.
A few days ago, someone told me that they were competitors before the bidding for the general contracting of the project, and after the general contracting, they shared money (work tasks) with each other.
Actually, it's just deciding which leader is responsible for the project. After the national bidding, the funds will be placed under the books of which winning group. In terms of detailed projects, those with high responsibility and professional abilities are more likely to be divided, while those with low responsibility are less likely to be divided. The procurement level is interconnected.
This is the case with China's aerospace industry. The aviation departments, 611, 601, and 603 are also similar. Transportation, railways, and various construction groups are also the same. Everyone is the biological son of the country. There is something that cannot be discussed (mutual procurement).
Production is one thing, and the specific design of weapon models is another (just like the relationship between 611 and Chengdu Aircraft Industry Group. One is for development and the other is responsible for production). CASIC is wary of technology loss, preventing the hypersonic units (aerodynamic research) of CASC and AVIC from stealing their hypersonic wind tunnel test data. CASIC has always planned to invest billions in its own exclusive hypersonic wind tunnels in order to prevent CASC and AVIC from obtaining their research results. There is no problem with outsourcing the production of weapons or equipment. In fact, this does not involve real core technology and does not make money (the production profit is tightly controlled by the state, with a lot of safety production and management responsibilities. The part that is easy to earn and easy to spend is the research and development funds for weapons and equipment). The core technology is how to design and the specific parameters of the design. These are all required in the weapon development task book.

China has tested new-gen ALBM twice. They made ten engines for endurance test and 6 missiles with 2 of them fired.

在一次重大研制任务中,研制团队需要开展10台发动机的高、低温试验,振动试验以及试车,同时还需要完成6套产品的生产研制和两发产品飞行试验,这样的交付进度几乎超出了四院重大型号研制能力的极限。
In a major development task, the development team needs to carry out 10 sets of engine (to do) high and low temperature test, vibration test and hot test , and also needs to complete the production development of 6 sets of products and two product flight test, such a delivery schedule almost exceeds the limit of the four hospitals of the major models of the development capacity.
吊耳是飞机下侧用于悬挂型号产品的装置,在某型号吊耳挂飞研制前期,刘长猛带领团队一边不断与总体进行协调,一边尽量按照总体提出的指标要求进行试验。吊耳的挂载试验时间长、次数多,而且每一次挂载完成后需对吊耳的应力等技术指标进行检测,需要细致和极大的耐心。
Lugs are devices used to hang "products" (ALBM)" on the lower side of the airplane. In the pre-development stage of a certain product of lug mounting, Liu Changmeng led the team to coordinate with the overall coordination while trying to carry out the test in accordance with the index requirements put forward by the overall. The loading test of the lugs is long and frequent, and the stress and other technical indexes of the lugs need to be detected after each loading is completed, which requires meticulousness and great patience.
经过不断的试验,吊耳的性能指标满足了总体要求,发动机的载荷集中问题也通过获得的试验数据对发动机进行局部优化得到了解决,填补了四院大型发动机载机吊挂技术的空白。
After continuous testing, the performance index of the lugs meets the overall requirements, and the load concentration problem of the engine is also solved by local optimization of the engine through the test data obtained, which fills the blank of the large engine-hanging technology of the 4th Academy.

TBH, judging by how China is exerting even more significant efforts towards the development of newer ALBMs (plus ALCMs and ALHMs too) that are to be launched from bomber-sized aircrafts, which are only going to get physically larger and more complex - It might be prudent for China to continue procuring more H-6Ns for some time, even as the H-20s are expected to enter active service with the PLAAF in the mid or late-2020s.

Perhaps Xi'an could continue the production run of the H-6Ns into the late-2020s - Or even the early-2030s.

Simply put, the H-20s will play similar roles as the B-2s and the B-21s, while the H-6K/J/Ns will play similar roles as the B-52Hs.

Otherwise, China could either restart the H-8 strategic bomber project using 21st-century technologies and knowhow - Or develop a BWB-based strategic bomber with much bigger weapons bays and a much larger payload capacity than the H-20.

Though, that's just my two cents on the matter.

A modernized H-8 would be too far unambitious. A subsonic 6 engine plane is still a subsonic 6 engine plane.

Feels like China missed the bus in the mid 20th century with the B-52 and Tu-22M era to build a big strategic bomber and building one now is a waste, might as well go for a semi-stealthy supersonic one or a super stealthy subsonic.

Or perhaps hypersonic long-range as part of the next generation of delivery platforms.
