ICBM tests went on September 17, still not clear whether it was from Taiyuan or Jilantai.

Which set it apart from previous tests is, there were actually two ICBM tests simultaneously and their drop zones were almost identical except very slight difference. Overall they had seven drop zones.

The second one is a werido, never seen such drop zones like this before.

As a complete nobody that knows nothing, the second one almost looks as if they are trying to expand the range of possible targets a single ICBM can hit within a trip. Perhaps to complicate things for missile defense networks? Anybody feel free to correct me if I am way off base.

Another interesting find during digging into a journal published in 2019, possibly PBV technology related.

Please, Log in or Register to view URLs content!

Key takeway:

1. CASC developed a 10kN upper stage engine a.k.a Post boost vehicle in 2018 with a chamber pressure 4MPa.
2. It has already been tested in a weapon system in September 2018.
3. Very likely to be designed for an ICBM PBV.

Longer thought:

The journal also stated that there were two engines using carbon fiber for their nozzles in China as of 2019. The first one is a 2.4kN one, conducted its first flight in 2013. I suspect this could be the DF-41 test in Dec 2013. The second one was YZ-3, upper stage for Long March 2D, a 5kN one. And it was said that they have already developed a 10kN upper stage engine in 2006 but it never came into production.

For comparison:

EngineRS-14RS-34RD-8662013 Engine2018 Engine
Thrust1.39 kN11.70 kN5.20 kN + 16 x 116 N2.4kN10kN
MissileMinutemanPeacekeeperRT-23Likely to be DF-41Unknown

The 10kN mysterious engine resurfaces again in the latest journal while engineers are talking about main engine of manned spaceship.

The Isp of 5 kN engine reached 307-308 s, and the first flight mission was successfully completed in 2018, with a cumulative ignition of 1,034 s in orbit. FYI, the so-called 5kN engine is called Yuanzheng-3 (AKA YZ-3)。
The 10 kN engine has completed several rounds of test runs, and the vacuum Isp has been increased from 305 s to more than 315 s
5 kN 发动机真空比冲达到了 307 ~ 308 s,于 2018 年成功完成首飞任务 ,在轨累计点火 1 034 s。
10 kN 发动机完成了多轮试车,真空比冲由 305 s 提高至 315 s 以上。

Further comparison with Isp on:

2023 Report comes sooner than I thought. Some interesting interpretation from DoD:

1. In 2022, Beijing continued its rapid nuclear expansion, and DoD estimates that the PRC possessed more than 500 operational nuclear warheads as of May 2023—on track to exceed previous projections.

"Told you so" to FAS report of 420 warheads.

2. The PRC is fielding the DF-5C, a silo-based liquid-fueled ICBM armed with a nuclear warhead with a multi-megaton yield (wtf??). The PRC is fielding the longer-range JL-3 SLBMs on its current JIN class SSBN, rendering them capable of ranging the continental United States from PRC littoral waters.

I don't know how they concluded that DF-5C will be a megaton bunkerbuster because DF-5B has been MIRV'ed since 2005. And the "JL-3" (which is still JL-2A/B in my interpretation) is operational as expected.
