China Ballistic Missiles and Nuclear Arms Thread


I wonder if the Chinese thermonuclear bomb done to the Yu-Min configuration got anything to do with the different yield as against USA thermonukes done to Ulam Teller configuration.
.
And that apparently the Yu-Min required a lot less maintenance than that of the Ulam Teller.

I tried but cannot find anything on the Yu-Min, unlike the ton of literature on the Ulam Teller.
Perhaps some folks here might guide me to Yu-Min configuration
interesting article from Globalsecurity that claim Yun-Min design is superior to UT

I thought the heavier W87-1 (newer model) has a yield of up to 475 kilotons (close enough to 500 kilotons), like the W88? Still, that is still distance away from DF-41 250 kg warhead's 650 kilotons. Anyway 100 kilotons would be enough to level a city in modern nuclear war.
I wouldn't be surprised that Chinese latest warhead is more advanced than American's W88 which was designed in 1970s.

But I'd guess that the latest version is called the W88 ALT 370 (First production Dec 2019) would be more advanced than the Chinese one

It would likely have newer electronics than the Chinese 1990s warheads at least.

But yield also depend on configuration, and US and China uses different types of configuration.

yes, different configuration. Thats why the accusation of stealing W88 design is just simply wrong. It is ingenious Chinese' warhead design

Maybe China has both designs? I must admit that I haven't read much on the Yu-Min configuration and knows very little about it. It gets mentioned from time to time but some detailed articles in the open internet would help.
Also scarce are the articles on JL-2B. What are the improvements made on JL-2 ? It is being improved ?

It can still be upgraded to 475kt if there is a need.

Thank you.

A partial extract from above. Bold emphasis are my doing.

relate that there are two kinds of hydrogen bombs currently in the world, one is Teller-Ulam [TU] configuration from the United States and the other is a "hypersensitive" configuration by Yu Min, an unique original hydrogen bomb configuration. IT is said that the hydrogen bomb design named the "Yu Min configuration", compared with the United States T-U configuration, is a configuration for which the cost and maintenance costs are relatively low, so it can be said that for the hydrogen bomb, Chinese technology is more advanced. It gives China the ability to maintain H-bombs in service.

Although atomic bombs and hydrogen bombs are both nuclear weapons, the two have different storage conditions due to different principles. The atomic bombs can be stored for long periods of time in a dry, constant temperature environment. The hydrogen bombs, due to the use of fusion materials, are very unstable and have a short life expectancy. The hydrogen bombs must be inspected, maintained and maintained regularly throughout their service. China's hydrogen bombs have adopted a more advanced and stable Yu Min configuration, basically eliminating cumbersome maintenance.

Since the 1970s, Yu Min played an important role in advocating and promoting a number of high-tech projects. He won the first prize of National Natural Science Award in 1982, the first prize of National Science and Technology Progress Award in 1985, 1987 and 1989, the "May 1st Labor Medal" in 1985, the "National Model Worker" in 1987, Guanghua Award 1992 Grand Prize.

Yu Min played a crucial role in the design of China's nuclear weapons, and is one of 23 recipients of the Two Bombs, One Satellite Achievement Medal, the country's top award to scientists contributing to China's nuclear and satellite projects. Yu Min won China's top science and technology accolade on 09 January 2015."

Yu Min existence and his very name was top secret in China until 1988


From the end of 1960, Yu was involved in the theoretical research of nuclear weapons. His major contributions included the solutions to a series of fundamental and critical theoretical problems of nuclear weapons, which led to breakthrough of hydrogen bomb.

Yu died in Beijing on 16 January 2019.

As I said earlier, to date very very little is known of Yu Min configurations, other than it is superior to Ulam Teller configuration.

I had been searching for at least a year , in both English and Chinese literature for the Y M configuration , and I came up empty handed.

And despite cries of 'Muricans to threaten to nuke China at about every turn ( If China DARE to attack USA carriers, China will be nuked, If China DARE to have war with Taiwan China will be nuked! etc etc etc) It is more likely than not that China might well have the only currently working thermonuclear bombs. As much of the time, USA need to change the tritium in intensive maintenance of their W88s and other devices.

How many working USA thermonukes there are at any time will be a very very good question to ask.

Not likely you be getting any answer though!

I've been thinking about possible configurations for a next-generation TEL for the DF-41 (and other missiles) - given China's advances in hybrid and electric powertrains - and I think it would be neat if it was a gas turbine hybrid. It would be much more powerful, lighter, and more fuel efficient than the current diesel engine, plus having an independent motor at each wheel would bring better off-road performance.

Just to play with some back-of-the-envelope numbers, if we take the HTF5980A/B to have an 800HP engine (similar to the MZKT-79221), and the next-gen hybrid TEL to have a 250HP motor at each wheel (with similar aerodynamics, wheel count, etc.), then the maximum speed would go up by 71%.
