DF-21D announced sometimes operationnal and sometines no, would be used by 2 brigades : 822 th ? and one other, each unit get 6/12 launchers as others DF-21 units.

But there would targeting technical problems and achieve a moving target with this kind of missiles would be very difficult with speed to correct the trajectory, many engineers are still very puzzled...

Yu Min(于 敏), the legendary academician of the Chinese Academy of Sciences, is rewarded the National Supreme Science and Technology Award today.

Yu was born in 1926. After got his bachelor degree from Peking University Department of Physics in 1949, he became an postgraduate majoring in theoretical physics. Then, he was chosen by CAS' Modern Physics Research Institute, which found in 1950, in 1951 after his graduation.

By the end of 1960, under the lead of great Qian Sanqiang(钱 三强), Yu, and other outstanding young scientists quietly began the theoretical research for the H-Bomb. Individually, switching from fundamental research to hydrogen bomb was a great loss for him. He was a born fundamental theory researcher, and had already made considerable achievements. The H-Bomb task was not only heavy and collective, but also would force him abandon his bright future on physics, hide his name, work on pathless wastelands and travell all over the country. He agreed.

Was him voluntary? I tend to believe a positive answer. Scientiffic research is professional, and the result varies with the enthusiasm and capability of scientists. If scientists were forced to do the task they believe harmful and unjustice, they would not devote themselves in. In contrast, they probably lie down on the job, even sabotage it, such as Heisenberg's "calculation mistake" which doomed the entire nuclear project of Nazi Germany.

A compulsory scientist would not risk lethal radioactive dose to retrieve nuclear warhead with detonate failure as Deng Jiaxian(邓 稼先). A forced scientest would not protect the technical data with his own body in the last seconds before the plane crash as Guo Yonghuai(郭 永怀). Most foreign people, and even some my fellow countrymen can not understand the spirit of that generation who just gave everything they were to the country.

Let's go back to Yu. The nuclear research took daunting quantities of cauculation. Today's China owns the fastest supercomputer on the world, but up to these days, the entire country has only one vacuum tube computer could reaches 10000c/s, and more than 90% of its time was
designated to A-Bomb work. Yu Min and his workgroup didn't yield to the difficulties, they used slide rule(I bet you cannot figure out what it is before searching on internet) to push on their job.

After four years of efforts, they mastered the phenomenon and pattern of H-Bomb theory. On Sept. 1965, Yu his squad moved to CAS calculate center in Shanghai to finish the verification of their model. After initial fail, they made it to find the key of self sustained combustion. The Yu Min model was born, it was completely different from Teller-Ulam.

However, his great achievement was unknown to the world——even his name had been classiffied til 1988!

Yu also directed the research of China's N-Bomb.

Luobupo lake, 08:20 on June 17th, 1967. China's first airdrop H-Bomb weapon test.

Only 2 years 8 months after the A-Bomb. Just 8 years after USSR uilaterally terminated their support: refused to provide the mathematical model and natural pattern of nuclear weapon, pulled back all personnel and data on June 20th, 1959.
"Project 596", the name of China's A-Bomb plan, was named to remember the day. The Sino-Soviet split reminds China again and again that on the road to great a nation could only rely on itself.

Salute to all the herotic scientists, technicians, and servicemen worked for China's nuclear program. Thank you for freeing the 3rd world from hegemonistic nuclear blackmail!

Inside story about China's first H-bomb development

On June 17, 1967, a small fighter plane released a parachute above the skies over Xinjiang, in northwestern China. When the parachute was 3000 meters above the ground, it exploded. With a huge "bang", a huge mushroom cloud arose.

China had the H-bomb! The news shocked the world because it took the US seven years and three months, and the former Soviet Union, four years and three months, to develop the hydrogen (H) bomb after the atom (A) bomb. However, China, which was then very backward in its comprehensive strength, only spent two years and eight months to develop the H-bomb after the A-bomb.

Forty years later, according to a China Youth Daily report, some experts recalled their stories and told us some stories from that time.

A breakthrough in H-bomb theory by young research team

There were 100,00 people working in the nuclear industry at that time, and 68% of them were below twenty-five years of age, while 25.5% of them were between twenty-six and thirty-five.

In May 1964, when former national leader, Mao Zedong, heard the third five-year plan, he pointed out that "China should have the A-bomb and soon it should have the H-bomb too."

Researchers, then, only knew the basic concepts of the H-bomb. As for how to manufacture the H-bomb,-what was at its core- none of them had any idea. Li Yanxiang, director of the office of the former Ministry of Nuclear Industry, recalled that for a period of time, the young research team felt they had run out of ideas. Complicated calculations became one of the main reasons for research being slow. In the 1960s, China only had one computer with a speed of 10 thousand times of calculations per second. In addition, it was used for testing the atom bomb most of the time. Research fellow, Yu Min, who was dubbed the "number one home-grown expert," and his colleagues, often used a calculator to count day and night.

One day they obtained an important reference number from foreign sources, but they questioned how this number came about. Therefore, they needed to test the validity of this number. Yu Min pondered this issue for days.

One night he woke up from a nightmare and he held his wife's hand shouting, "I got it, I got it, it's clear to me, it's clear to me!"

Li Yanxiang said that by 1965, research of the H-bomb had made great progress. As a result, dozens of science and research personnel traveled to Shanghai from Beijing. At that time, everybody had to take their own backpacks because there were not enough quilts available for them in Shanghai.

The computer had to print every result out on paper and people had to read the paper that sometimes was held in large linen bags. They spent a lot of time reading these data and were careful with every sheet of paper so as to preserve the accuracy of the data.

Beginning in September 1965, after 100 days of calculation, there was a breakthrough. After this, research was on the fast track. "Deng Jiaxian, who was in Beijing then, immediately came to Shanghai upon hearing the news, and invited all of us to lunch. Although it was just a bowl of noodles, we were all very happy," Li Yanxiang reminisced.

Statistics showed that Deng Jiaxian was just 34 years old at the time; Zhu Guangya, also 34; Zhou Guangzhao, 32; and Ou Yangyu, 31. At that time, 90% of the 100,000 nuclear energy researchers were between the ages of 25 and 35 years.

The battle in the 'Golden Sand' area

While researchers conducted experiments with A-bombs and H-bombs in the 'Golden Sand' grassland in Qinghai province, in northwest China, the 221st site was being built. It became China's first nuclear factory.

Seventy- year- old Wang Jingheng was the director of the factory. He graduated from a famous university in 1960 and then he was sent to the ��frontline'. In January 1961, Wang Jingheng and his four classmates traveled from Beijing to Lanzhou by train. However, a train from Lanzhou to Xining did not exist, so they had to sit in a cargo train. The cold wind made their hands and feet feel dumb. They only shared one cotton overcoat during the ten hour trip. From Xining to the site, traffic not exist either. As the Chinese New Year was approaching, they all had to stay in Xining for a week, in order to wait for a cargo truck that sent daily necessities to the site. They sat on pots which contained pickled dishes. They survived the cold wind and finally arrived at the site by truck.

At that time, there were hundreds of thousands of people in the site, living in caves and eating barley and millet flour with a little oil. The only dish they could eat was Chinese cabbage soup. If they felt hungry, they could gather wild vegetables. Wang Jingheng said although life was hard, people's spirit were very good, hopeful, and positive.

At that time, they all had to keep their discovery a secret. The place was also a mining area. In addition to the lack of oxygen, the ultraviolet rays from the sun were very strong. Many people's skin became very dark. Nevertheless, they could not reveal to their families the true nature of their work. When some people went home, their children asked: "Daddy, while you work in the mining area, do you dig up coal everyday?" Father could only say "yes."

Li Yanxiang said he thinks it is still of great significance to recall the successful launching of the H-bomb forty years ago. Particularly in the high-tech field, leaders and researchers should be as confident as those who worked forty years ago.

I wouldn't say all US report about China's military is stupid. Gertz is a well know idiot, in this article he just demonstrates he can't even paraphrase correctly. The AACP report he mentioned is talking about the appearance of the new generation of Chinese TEL vehicle, which bears similarity to Russian TEL design, not that DF-41 missile is based on SS-25. Well of course, China is know to have licensed Russian off road heavy truck design. Only idiots like Gertz would believe that Russian would sell strategic missile technology to China.
Gertz writes ideological driven propaganda pieces, not serious analysis.

Actually, china has/had agreements with a MZKT, a Belarus company which manufactured the soviet heavy trucks in the USSR era. No russian envolvement in that. But the latest chinese TEL dont seem similar to ex-soviet ones.

most of soviet TELs were manufactured in belarus anyways, it is apparently years ahead of russia and even the US in this field, as a result of strong demands stemming from its marshy road condition

Question: can a missile guide herself from sun? Like old sailors?

I've tinked to a sattelite as an artificial star. What is best is how can be that jammed? Cause i dont think how. Also a vertical and horizontal compass can be used. Also star recognition , shadow calculation on earth, zooming whit video and calculate distance etc etc etc laser reflectors.

I suggest you research and read up on the ballistic missiles of each country before you ask over here.

And yes, China's DF series of ballistic missiles have astro-inertial guidance system (Celestial navigation / "guided by stars") built-in along with BeiDou Navigation Satellite System. It most likely also have ring laser gyros inertial guidance system as backup.

As for your idea of shadow calculation on earth, zooming whit video and calculate distance - they sound quite novel, although I think they will prove to be unreliable shadow is not a reliable measurement when there are cloud cover also how shadow falls on the terrain can be misleading - it might be able to give a extremely rough estimate by it would be practically useless measurement. Modern ballistic missiles needs to be accurate to within 200 meters minimum - some are even within 30 meters or less. Using shadow would just be too inaccurate to be useful.

huh? can someone elaborate on how that tech helped the MIRV development?

They are talking about the bus what places multiple satellites on different orbits. Useful technology when you want drop MIRV's on many different targets with one bus.

I think that Chinese military sees MIRV's as a dead end strategy because in future ABM systems will be able to destroy MIRVs easily as they take out one RV and that's why they are developing things like WU-14.

China’s hypersonic strike vehicle ‘in 3d test flight’

China has reportedly conducted a third flight test for its new ultra-high speed strike vehicle – capable of travelling at up to eight times the speed of sound, in what experts suspect is part of the development of its strategic nuclear program.

The test flight, monitored by US intelligence services this week, was the third in a series of tests of the Wu-14 hypersonic glide vehicle—a high-accuracy, high speed projectile, reports the Washington Free Beacon. The first two were conducted earlier this year.

A Pentagon representative confirmed the test to the WFB, but declined to provide further comment.

“We are aware of reports regarding this test and we routinely monitor foreign defense activities,” Marine Corps Lt. Col. Jeff Pool said. “However, we don’t comment on our intelligence or assessments of foreign weapon systems.”

Lora Saalman, a nuclear policy expert at the Carnegie Endowment for International Peace, said China’s third test of the Wu-14 in a year suggests an ongoing trend of militarization.

“Not only does this third test of the WU-14 in one year indicate that this is a priority program for China, it also suggests that U.S. historical concerns over a Chinese quantitative ‘sprint to parity’ in nuclear weapons are misdirected,” she was quoted as saying in the Beacon.................
