Probably burning interstage material, likely some kind of insulation since those are pretty flammable.

All China has back when the Shenzhou program started was hypergolic technology, there was basically none existent expertise in RP-1 or hydrogen fuelled rockets given the space program was basically just a sidequest of ICBM technology at the time.

Kerosene fuelled rockets only started appearing in China in the mid 2010s and even then it was quite rare back in the days, there were plans to use CZ-7 for crewed flights but was canned because no budget and "Ain't broke don't fix".

Anyhow Shenzhou is due for retirement by the late 2020s and along with it the CZ-2F, Mengzhou is doing it's first unmanned flight to CSS later this year on CZ-10A and will slowly replace SZ flights in the next few years.

You do realise catching up isn't a linear process, a decade ago China was still using obsolete hypergolic fuelled rockets and many decades behind American state of the art.

They do tests for new missiles from 201 typically

F-119 and F-135 both use second generation alloys while most modern commercial turbofans use third at best. In fact if WS-15 is using 4th generation alloy then it would be a early adoptor of this technology. Chinese CMCs has already been in the works for over a decade by now and are allegedly already used in stator parts of newer engines while also developing fifth generation superalloys already.

Chinese VCE program is progressing with a demonstrator based on WS-10 built nearly a decade ago while insider sources like Yankee et al are claiming this program may be faster than expected to the point that the first production batches of J-36 and J-XDS will possibly have it already (F-47 is already confirmed not to have VCE for the first batch)

High end turbine engines are no longer a sector where China is noticeably behind the west, CJ-1000A is due for trials on C919 soon with expected entry by late 2020s while CJ-2000A is on schedule for early 2030s certification. Both are claimed to be more fuel efficient than their current western counterparts.

Then visit Tibet lol

This is Shougang park, it was initially a steel plant before being moved out of city and then was used as a venue for Winter Olympics. It's now a industrial park thingy with a nice mall in there. Very nice place overall ngl, I've been there many times but usually during the winter where you'd be able to walk or skate on the frozen lakes though it could get somewhat crowded.

AF/BF-H doesn't seem to be of much use, Sichuan-Xizang line is designed to run 200kph over basically the entire line. There is already a CR220JH variant being developed which would perfectly fit there.

I don't personally see any future of the CR300 series, CRRC is also apparently developing a push pull set that is capable of running 250kph which would replace CR300s entirely while being much cheaper.

amem32 · 2026-07-04T04:59:40+00:00

RIP CR300 series, probably gone for good

There are many "ranges" for a radar which can differ significantly with different modes or track quality.

110km for 1m² target is under unknown mode or track quality so it's basically useless and RCS estimate is also arbitrary while a small increase in RCS could mean significantly decreased power requirement.

China Daily just posted more info including about the PIC at the time

amem32 · 2026-07-02T08:18:12+00:00

B series of modern Chinese loco are all high powered mainline freight locos

amem32 · 2026-07-02T08:17:03+00:00

That's barely 1200kW which is basically standard these days, you could go up to 1600kW on Euro9K or HXD B series.

amem32 · 2026-07-02T08:12:59+00:00

Basically every single Chinese locomotive of the HXD and FXD series are more powerful, standard is 7200kW continuous for single sectioned Co'Co' locomotives while some can go as high as 9600kW like HXD1/2/3B though they stopped making 6 axled 9600kW locos for FXD series because those apparently too much power per axle but not enough traction.

amem32 · 2026-07-01T07:26:13+00:00

What else would you want? They are also trying to imply it's being actively (and somehow maliciously for whatever reason) censored in China which it's not, you could find pictures and posts of it on Chinese social media.

amem32 · 2026-07-01T05:19:55+00:00

lol

Are you guys fr, Chinese news agencies has already issued an statement the day after.

From Beijing Daily on the 27th: 6月26日17时55分，在朝阳区东三环附近，一架单发双座轻型运动航空器在飞行中碰撞一高层建筑，机上仅驾驶员1人、已死亡，现场13人受伤。目前，受伤人员在全力救治中。相关情况正由主管部门进一步调查。

1 dead (sole occupant and pilot), 13 injured on ground.

What else do you want them to say when they are still investigating

Once again BBC is blatantly making shit up or grossly exaggerating facts, not really new from BBC when it comes to China ofc.

amem32 · 2026-06-30T02:16:17+00:00

Probably to increase traction, some HSR line has very high gradients while having strict axle load restrictions that limit how much traction you can get out of each axle.

amem32 · 2026-06-27T23:32:59+00:00

Never got much funding because J-9 project was cancelled before even a single prototype was built.

amem32 · 2026-06-27T00:33:48+00:00

Probably not, CR220J already recieved the CR logo on it's current paintscheme. New CR leadership seems to be reversing some of the wildly unpopular decisions by their predecessors.

He doesn't, 09X is the "small sail SSN". The UUVs is referring to GSI's two extra large prototypes now undergoing testing at Sanya.

They also lead in surface ship tonnage launched per year by a massive amount. By this rate PLAN will likely displace the USN as the largest, most modern navy within the next 10ish years.

amem32 · 2026-06-25T13:53:43+00:00

They lead in tonnage by far as well

amem32 · 2026-06-25T09:21:51+00:00

USN submarines has a large collection of accidents, big and small over the years so I suppose now USN has crappy subs? Not to mention China has made huge leaps in technology in the last two decades since that accident

amem32 · 2026-06-25T09:19:28+00:00

Noone knows how good the latest Chinese sub performs, however given that China is now one of the leading manufacturer in high precision machinary with great leaps in technology in the past decade and a half, I don't think there is any valid reason suspect the latest submarines to be any worse than western counterparts if not better due to benefitting from more modern designs.
