Interview with 李洪, Deputy General Manager of China Aerospace Science and Technology Corporation, here's the interesting part:


"Besides the construction of the space station, the 14th Five Year Plan also contains one other 'big fella' to watch out for. Our nation is currently developing the super heavy lift Long March 9 in the 100 ton to LEO class, four times the payload capacity of Long March 5. Currently its 500 ton kerolox engine development is actually successful. This rocket will be responsible for manned lunar landing, Martian exploration and other missions. Li Hong says it is possible Long March 9 will achieve maiden flight within 5 years. 'Once these technical challenges are overcome the construction will happen at a rapid pace as we've already prepared for it. I believe it can be achieved towards the end of the 14th FYP. If it achieves four times the payload of Long March 5 then it will be able to deliver much more payloads to deep space and open up many more modes of exploration, including experimentations post Lunar landing. This will greatly expand the avenue for scientific exploration as well as practical application of new scientific developments.'"
Just to clarify, is the 140t to LEO for the LM-9 a misnomer? I remember people saying it is in the same class as SLS.

Either just figure of speech like calling the 13,000 ton type 055, "10,000 ton class destroyer" or this is referring to early configuration with smaller payload like SLS Block I (95t), with the full 140t version will be ready in 2030.

Seems the 921 rocket is gone.

This is one of the reason I criticize the "new age" reporters being unprofessional. Here is why, the red bold texts are quotation of Li Hong's words. The rests are the reporter's own words.

Firstly, the reporter mixed her own understanding of what the interviewee said with the quotation in the same paragraph. This does not make it clear of what was the question, what was the answer, what was the interpretation. A professional interview should separate these in different paragraph with the heading like "Reporter:", "Interviewee:".

Secondly, her interpretation (in black bold texts) asserted 100t LEO, qualified the figure with "is 4 times of CZ-5". This firmly put CZ-9 at 100t LEO. However, the Li Hong's original words was "greater than 4 times of CZ-5's LEO capability". Greater than 4 is totally different from 4. Yet, she did not verify her interpretation with the interviewee, but rather assumed being right. The worst is that she did not put her report in the format that I proposed above. It is not like the reporter (knowing nothing) ask for an answer, but rather the reporter makes her mind then get some professional person to back her up with twisted interpretation.

除了空间站建造,“十四五”时期,还有一个“大块头”值得期待。我国正研制的超重型长征九号火箭具有100吨近地轨道运载能力,是长征五号的4倍。目前,其500吨级液氧煤油火箭发动机的研制工作已取得成功。这款火箭主要负责未来的载人登月、探测火星等任务。李洪表示五年内长征九号有望实现成功飞天。“一旦那些技术被攻克,工业制造能力做好了准备,也是很快的。我认为‘十四五’后期应该能够实施。如果是大于现在的长征五号火箭4倍能力的运载,将来要在深空探测方面可以投送更多的有效载荷,可以有更多的探测形式,甚至于布局落月之后的一些试验等,对全球、对中国(来说)整个的科技探索、科技实施空间就更大了。

There are three proposed configurations of CZ-9 by Long Lehao. The following slide was from a presentation by Long Lehao in 2017.
cz9ppt3.jpg

The left most is the 140t version (CZ-9) with four boosters. The middle one (CZ-9A) is 100t with two boosters. the right one (CZ-9B) is 50t without boosters but 5 engines in the core instead of 4.

In the presentation, Long Lehao said "CZ-9 (140t) is our plan, the initial test may be conducted by CZ-9B, CZ-9A and B may not be ever typified, depends on if there is a need for them".

So my understanding is that, strictly speaking CZ-9 is 140t, the other two are possibilities that may never be built. Anything other than 140t (now it is 150t) are misunderstanding or misquotation.

As of comparing to NASA's program, CZ-9 is comparable to Ares V (150t 240x240km LEO). SLS block II cargo at 130t is the down-sized Ares V.

Li Hong says it is possible Long March 9 will achieve maiden flight within 5 years.
I think Li Hong meant the initial flight test of CZ-9 program may happen in 5 years instead of the maiden flight of CZ-9. The initial test planned (according to Long Lehao) was probably the configuration of CZ-9B (without boosters). But this variant together with the two boosters variant may never be typified. So they are test articles during R&D rather than a planned product for application. Also CZ-9 strictly speaking is only meant to be the four booster variant. This goes the same as CZ-5 being the 2.5 staged version while the 1.5 staged is CZ-5B. Although they are in the same CZ-5 family but CZ-5 is also the designation of a specific rocket.

I see, thanks for the information. I suppose we'll see in... hopefully 5? years time for a first launch as the person stated.

The recording is transcribed word for word to the following texts in the report. The blue texts are the reporter. The red are Li Hong.
空间站建造,“十四五”时期,还有一个“大块头”值得期待。我国正研制的超重型长征九号火箭具有100吨近地轨道运载能力,是长征五号的4倍。目前,其500吨级液氧煤油火箭发动机的研制工作已取得成功。这款火箭主要负责未来的载人登月、探测火星等任务。李洪表示,五年内长征九号有望实现成功飞天。

“一旦那些技术被攻克,工业制造能力做好了准备,也是很快的。我认为‘十四五’后期应该能够实施。如果是大于现在的长征五号火箭4倍能力的运载,将来要在深空探测方面可以投送更多的有效载荷,可以有更多的探测形式,甚至于布局落月之后的一些试验等,对全球、对中国(来说)整个的科技探索、科技实施空间就更大了。”

Li Hong did not say anything about CZ-9's flight, partial test or maiden. The "CZ-9 flight in 5 years" is the reporter's own words without any reference to the interviewee.

The recording apparently is recorded over telephone, not a face to face interview. Since the original report in text ended at exactly the red texts, I believe the recording is complete in case of CZ-9.

Regardless, the report is so bad in quality and only added confusion.
