National Defense (THAAD) is the only land-based high-altitude long-range anti-missile system that can intercept ballistic missiles inside and outside the atmosphere. The general contractor is Lockheed Martin. 1989 put forward the scheme of "sade" system and started a series of verification tests. In 2000, "Sade" system was transferred to the engineering development stage, and the deployment of the first system was completed in 2008.
The "Sade" system is an important part of the new US missile defense plan. Mainly for intercepting high-altitude missiles, satellite, infrared and radar integrated early warning modes are adopted. The system consists of interceptor, vehicle-mounted transmitter, ground radar and operational management and command, control, communication and intelligence system.
The most striking technology adopted by "Sade" is the "kinetic energy killing technology" of its kinetic energy killing bomb (KKV). This is a new technology developed from the "Star Wars" project, and its destruction mechanism is "collision and killing", which is extremely destructive. This method seems simple, but it puts forward high requirements for the vector technology of terminal guidance and space maneuver, and the difficulty is no less than "bullet by bullet".
Previously, air defense and anti-missile missiles generally used high explosive fragments to kill target missiles or warheads, and relying on thousands of fragments to destroy target missiles or warheads often only achieved so-called "mission destruction" rather than "missile destruction". Generally, the warhead is not completely destroyed, but deviates from the original track, and the explosives or chemical and biological warfare agents in the warhead will still be scattered to the ground.
For nuclear warheads and biological warheads, deviating from the original orbit may prevent the warheads from landing on the original targets, but if the final landing point of the warheads is an enemy country, from another perspective, the warheads have already completed the task of killing the enemy country-because no one can guarantee that the new landing point is not a densely populated area or a large industrial area of the enemy country. And "collision and killing" can hit the target warhead at high speed, thus detonating the warhead at high altitude or using the high heat generated by high-speed impact to disable the chemical and biological warfare agent.
Another advantage of "kinetic energy killing technology" is that its warhead is very small, even without special killing parts. It can achieve the effect of "collision killing" only by relying on the quality of guidance or terminal moving parts, which greatly reduces the quality of warhead. For example, in the early scheme of "Sade" system E2 1, the mass of its kinetic energy killing vehicle (KKV) was reduced from 200 kg of the previous "high altitude defense interceptor in the atmosphere" to 40 kg, while "Sade"
The mass of the interceptor of the system, including the protective cover, is only 40 ~ 60 kg, which makes it possible for the missile to increase the interception height.
The so-called "protection" is actually "deterrence"
"Nominally, South Korea's deployment of' Sade' is aimed at North Korea; It is actually aimed at China and Russia. " Ren Weidong, an associate researcher at China Institute of Contemporary International Relations, said in an interview with this newspaper.
Ding Shizhen, the former unification minister of South Korea, pointed out in an interview with the media that South Korea and the United States decided to deploy "Sade" in Gyeongsangbuk-do instead of the metropolitan area, which just proved that the purpose of deploying "Sade" was not to deal with North Korea's nuclear and missile threats, but a military technical measure taken by the United States to safeguard its hegemonic position in East Asia.
Many analysts have pointed out that if it is only aimed at North Korea, the "Sade" anti-missile system far exceeds its demand. Geographically, the Korean peninsula is 360 kilometers wide from east to west and 1000 kilometers long from north to south. If this area needs missile coverage, there are enough short-range ballistic missiles with a range of 1000 km, and there is no need for a defense system that mainly attacks medium-and long-range ballistic missiles with a range of more than 3,500 km, like Sade.
Moreover, the detection distance of "Sade" radar is 2000 kilometers. It only takes 8 hours to switch between two deployment modes: forward deployment and end deployment. If the US military starts the 2000-kilometer detection radar 24 hours from the second day of deployment, the military activities in the Far East and China are likely to be exposed under the eyes of Americans.
When talking about the reaction of Russia and South China to the deployment of the Sadr anti-missile system by the United States and South Korea, Trofimchuk said: "As we all know, Beijing and Moscow have expressed concern about this incident at the official level. But at the same time, we should still pay attention to the experience of the United States in deploying anti-missile systems in some eastern European countries of the European Union. Because experience shows that expressing concern only verbally will not have an essential impact on terminating the deployment of anti-missile systems, and even accelerate its progress. " "Even if the North Korean leader does not show his strength in the field of military technology research, Washington is likely to find other excuses, because this kind of thing is very common in Asia."
Trofimchuk suggested that to prevent the Sadr incident from escalating, we should not confine ourselves to some official statements, but take a series of deliberate and concrete actions.
He said: "The problem should be solved where it appears, so it is of vital significance for North Korea and South Korea to have a dialogue. There is great potential for dialogue between people from different regions of the same ethnic group, but this potential has not been fully utilized. The people on the Korean peninsula need peace, not war. This is our starting point. "
"Sade" entered Korea, and the consequences were endless.
China has repeatedly expressed strong dissatisfaction and resolute opposition to the deployment of the "Sade" system by the United States and South Korea, and said that it will consider taking necessary measures to safeguard national strategic security and regional strategic balance. The Russian side also said a few days ago that in order to cope with the entry of "Sade" into South Korea, the possibility of accelerating the restoration of the military base in the South Kuril Islands is not ruled out.
The situation on the Korean peninsula may also be more tense because of the entry of "Sade" into South Korea. North Korea responded by launching missiles several times in July, and warned that once the United States and South Korea decided on the location and place to deploy the "Sade" system in South Korea, the DPRK would take "physical measures" to deal with it.
William jones, director of the Washington office of global strategic information in the United States, also pointed out: "Sadr will not work, which has also been criticized by relevant personnel who have been engaged in missile system research in the United States for decades. They pointed out that it may be difficult for Sadr to make South Korea resist missile attacks from North Korea, but it will lead North Korea to make more radical moves. "
Experts pointed out that "Sade" entered Korea, making the ghost of "New Cold War" linger in Northeast Asia. As Sergei Lujanin, director of the Far East Institute of the Russian Academy of Sciences and a famous expert on China, said, the US-South Korea push to deploy the "Sade" anti-missile system in South Korea is the most serious military provocation in Northeast Asia in recent years, which is simply creating a new tense atmosphere.
