Yunfeng / Cloud peak
The Chinese Academy of Sciences has developed the "Yunfeng Intermediate-Range Missile", a surface-to-surface missile with a range of 1,500 to 2,000 kilometers, which has been successfully tested at the end of April 2020, and is expected to start mass production next year. The Yunfeng Missile’s research and development plan was shelved during the term of former President Ma Ying-jeou because of the slowdown in cross-strait relations. It took 10 years to promote it again under President Tsai Ing-wen.
This missile is said to have a range of 1000-1500 kilometers, high-altitude cruising, and a cruising speed of Mach 2.5. According to the technical speculation, it should be very large to reach such a long distance. According to the disclosures of some Taiwanese media, this missile may be launched to high altitude using a solid booster, and then start the ramjet. It is similar to the foreign trade Super Patrol 1 missile developed by the mainland. Of course, the cruise speed of Super Patrol 1 can be Up to Mach 3, its engine technology is much ahead of the "Yunfeng Missile".
According to reports, the Yunfeng Missile carried out a propulsion rocket flight observation at the Jiupeng base in Pingtung at the end of April, as well as a test firing of the missile’s new components and system integration. As a result, the flight conditions were all good, and the whole system was launched in the second half of the year. After verification of the ammunition, a budget will be officially formulated in 2021 for the mass production plan of the Yunfeng medium-range missile (high-altitude high-speed cruise missile) with a range of 1,500 kilometers. In the future, 10 sets of mobile systems and 20 combat ammunition will be mass-produced and deployed in the province.
Taiwan's green media immediately entered the state of performance, claiming that the "Yunfeng Missile" can cover the northern part of the mainland and can preemptively attack military bases on the mainland and undermine the PLA's preparations for military operations in Taiwan. Veteran media person Ma Xiping pointed out in the news program "Critical Moments" broadcast on the 27th, "Taiwan's military has done what I think is big today!" Taiwan has two missiles that the military never admits. One is the Yunfeng missile, the other is the Tiangong 2B missile, why don't you admit it? Because these two are "attack missiles." Ma Xiping said that as a result, the military officially admitted today that the first Taiwan had the Yunfeng missile, the second Yunfeng missile was successfully tested, and the third Taiwan will mass produce the Yunfeng missile next year.
The host Liu Baojie asked back, did the mainland have known it? How else would you put the S-300 air defense missile on the opposite side of Taiwan? Ma Xiping said, "I have already said that we will release missiles for Dongyin." So now Fujian has released 128 S-300s, Beijing has released 5 battalions of Red Flag-9, Shenzhen also has Red Flag-9 and Hong Kong has Red Flag-6. , The increased deployment is no longer attack missiles, all defensive missiles.
Ma Xiping further explained that the Yunfeng missile is a high-altitude cruise missile, which is launched through rocket thrusters. This is the most difficult technology. The Yunfeng missile is pushed up by 4 rocket thrusters, and 4 rockets are pushed to a fixed location. The missile itself The impulse thruster ignites again. After igniting, the height cannot be changed, the direction cannot be changed, and then it can be hit. "This is the most difficult technology in the world." Ma Xiping said that he dared to explain the annual mass production because the height and direction of the test firing were in accordance with our expectations, "so we recognized the Yunfeng missile for the first time."
The "Yunfeng Missile" can penetrate defenses at a height of about 10,000 meters at Mach 2.5. For the PLA air defense system, it is not difficult to intercept. To intercept such high-altitude cruise missiles, the PLA Air Force is has units equipped with J-11, Su-30, and J-8. After all, intercepting high-altitude and high-speed targets is precisely what their weapon system is designed for. The type of mission, and the target will not resist, it will only fly in a straight line. This is the best combat airspace for S-300 and Hongqi-9 missiles, with an interception distance of more than 200 kilometers, not to mention that for modern cruise missiles, the most effective interception method is air-to-air missiles. Even the J-8F fighter jet can easily shoot down 4 incoming Yunfeng missiles with Pili-12 missiles at the same time, and the interception efficiency of the J-10 and J-11 main fighters has improved.
The Yunfeng Missile can "preemptively strike" during wartime and cause trouble to the PLA's military reunification operation. Here we haven’t said where the Taiwan military intends to deploy the Yunfeng missile. In fact, the deployment base of the Xiongfeng 2E missile has been discussed online, and under the current power comparison between the two sides of the strait, this has been exposed The base is vulnerable to being destroyed at the outset of a war. So in Taiwan, where any disturbance will be discovered immediately, where can the "Yunfeng Missile" be deployed to avoid the mainland's intelligence methods that monitor all kinds of clues 24 hours a day?
The origin of the Yunfeng Missile Project is the same as the origin of Xiongfeng 3, which can be traced back to the 1970s and 1980s. Sino-US relations improved and Taiwan became an "Asian orphan". At that time, the United States stopped many direct arms sales to Taiwan. Taiwan’s missile program also made breakthroughs during this period, producing the "Tianjian" series of air-to-air missiles, the "Tiangong" series of surface-to-air missiles, and the "Xiongfeng 1" and "Xiongfeng 2" anti-ship missiles.
According to the United States, these missiles are all "defensive" weapons for the Taiwan military, because they are mainly used to improve the ability to stop the PLA fleet and aircraft groups, and the Taiwan military cannot directly attack the mainland with them. Including IDF fighters, the name of this project is called "Homemade Defensive Fighters", so it has a short range and cannot carry many ground attack weapons.
But of course the Taiwan authorities are not reconciled to this. They once wanted to develop nuclear weapons. As a nuclear weapon delivery tool, of course, there is no better than ballistic missiles. Atomic bombs and ballistic missiles were things that could be developed by major countries in the 1940s and 1950s. Taiwan already had a considerable civil industrial base at that time, and there was actually no technical problem to develop such weapons.
In this regard, Taiwan made some progress. It developed a liquid fuel surface-to-surface missile "Qingfeng Missile" with a range of 130 kilometers that was actually a product imitating the MGM-52 missile. Later, it has developed a solid fuel rocket technology that is the same as the Tiangong surface-to-air missile, and it has developed "Sky Horse Missile" with a range of over 300 kilometers.
In terms of guidance technology, very little is publicly known about the level of the Taiwan military, because after all, their development is carried out under high secrecy, and even the American father has to pretend to hide it. However, their technical level is not difficult to understand. Although Taiwan has always boasted how to lead its own electronic technology, it is actually not good at this level. According to Taiwanese media, the gyroscope used on the Xiongfeng 3 missile was originally intended to be purchased from the United States, but the United States has long banned the export of gyroscopes that can be used on missiles. And the funny thing here is that Taiwan found out that it was also banned from selling when it actually asked the Americans. According to Taiwanese media reports, a person familiar with the matter disclosed that the "Chinese Academy of Sciences" is "using domestic manufacturers to purchase the required components and materials in different names and methods from Europe and Russia." In other words, it is said that Taiwan has completed the inertial navigation and radar guidance heads of the Xiongfeng and Tiangong series missiles by smuggling commercial parts. Needless to say, the quantity and price of such smuggled parts are definitely problematic, and the performance cannot be compared with the serious military products. In 2018, the United States opened the sale of high-performance gyroscopes and radar components for missiles to Taiwan. This is also an important basis for Taiwan's confidence to start mass production of land-based versions of Tiangong 3 and Tianjian 2 and to restart the development of a series of missiles such as the "Yunfeng Missile" in recent years. There are several guidance methods for land attack cruise missiles. The first is inertial guidance. Under modern technical conditions, it is necessary to use multiple high-precision laser gyroscopes to form strapdown inertial navigation. This technology can achieve a maximum accuracy of circular probability error is less than 10 meters. Of course, there are only a few countries in the world that master this level of technology. Normally, the accuracy of using inertial guidance alone can reach 50 meters. So to improve accuracy, one way is to correct the accumulated error of the gyroscope through satellite positioning. This can increase the accuracy to the meter level, and as long as the satellite signal is stable, high accuracy can be achieved at any range. High-performance laser gyroscopes are not available in Taiwan, and they could not be purchased directly from the United States before. They can only buy some commercial products. Of course, there are some other technologies, such as terrain matching technology, which is to install a radar altimeter on the missile, detect the terrain passing underneath all the way, and then match it with the digital map to determine whether the missile has deviated from the route, then correct it and return to the schedule On the route. The technology itself is not difficult. The difficulty lies in the need to establish a high-precision digital map covering the entire combat area... This is a bit demanding for the Taiwan military. After all, their "Yunfeng Missile" is a "black box project" with limited funding. , There is not so much money for them to do something like this. There is another one, which is the target radar imaging or infrared and optical imaging at the end, and then the target image matching is performed. The more advanced one, and the data link can directly realize the human in the loop, so that the operator in the rear can see the missile transmission. Return the target information, and then specify the target to attack. This can achieve high accuracy. However, the distance of data link communication cannot be too far. There is no automatic identification of people in the loop. This is another matter that requires a high level of technology. If the level is not too high, it is easy for the missile to hit other targets. went. After a comprehensive analysis, the Yunfeng missile with a range of more than 1,000 kilometers is most likely to use satellite-corrected inertial guidance technology. The Super Patrol No. 1 missile may be similar in concept to the Yunfeng missile. Of course, the flight speed is much faster, but the range is only 280 kilometers due to export legal restrictions. Of course, look at the Yunfeng missile to know the potential of this thing. It should be said that the Yunfeng missile has an American gyroscope, coupled with GPS navigation, and has a certain practical value. In theory, it should be able to achieve an accuracy of several meters at a range of 1500 kilometers. Now, it shows that there is a problem with Taiwan's technological integration capabilities-of course this is also a high probability event. But even if its circular probability error is at the level of 20-50 meters, it can be considered to have a certain usefulness. On the basis of the principle of "feeding the enemy with leniency", we still need to pay attention to it. After all, missile technology has developed rapidly in recent years. Even Iran has the "Conqueror 110" series of missiles with very good accuracy. They can drop dozens of rounds in a base and destroy canteens and dormitories. Oil depots, runway intersections, and other key targets, but not killing a single person, which in itself shows its extremely high accuracy. With the artifact provided by the United States, the high-precision laser gyroscope, the "Yunfeng Missile" technically the biggest problem in guidance accuracy has been solved. Then the key issue that determines whether the Yunfeng missile can have combat capabilities is pushed to the next one, how many Yunfeng missiles Taiwan can produce, and whether such missiles can break through the mainland's air defense system. Taiwan declared in 1997 that "Tianjian 2" air-to-air missiles had begun production. By 2004, some media disclosed that in fact only 210 missiles had been produced in the past few years, which means that for the 130 "Jingguo fighters", two missiles are not good enough for an aircraft. After 2010, Taiwan had produced several batches of this type of missiles, but since there is only one IDF missile that can be used with the Sky Sword 2, it is useless to produce more, so the number is only a few hundred rounds. In contrast, how much is the production of the mainland’s Jili-12 missiles? At the very least, the number of missiles in the Mainland's stock should be in the thousands. From this comparison, we can infer that a missile factory like a workshop in Taiwan can produce several hundred "Yunfeng missiles." Taiwan can produce one or two hundred missiles in ten years, when the opponent is producing several thousand missiles. Can Taiwan still want to engage in "deterrence"?
