6 June, the Israeli Defense Ministry announced that the army will be deployed later this year “Iron Dome” missile defense system. 11, China announced the success of ground-based midcourse interceptor test. For a time, ABM has once again become the focus of international attention. Arms control expert Professor Li Bin, Tsinghua University, said the missile interception technology can be divided into two, one is struck interceptor missile using fragmentation, such as the U.S. “Patriot” series of anti-aircraft missiles; the other is the direct interceptor impact to destroy incoming missiles, such as China in the middle ground-based interceptor test used in the interceptor missile, the interceptor missile is mainly used for the middle block, the higher level. Currently the major countries of the missile intercept test more for the end of the block, the middle block of the technical requirements are higher.
based ballistic trajectory, the missile interceptor to intercept the initial segment can be divided into (boost phase interception), the middle block (to intercept the missile inertial flight phase) and terminal intercept (intercept missile re-entry phase), Most countries are at the end of the missile intercept test intercept test.
initial segment of the block
do not fly with a laser to intercept
Beijing News: Missile launch fast enough, and with a strong infrared signal, why not intercept the initial segment?
Li Bin: In theory, the missile to intercept the initial segment is indeed the most likely. But the fact, to launch ballistic missiles, intercontinental ballistic missiles in particular countries are regional powers, generally have a broad strategic depth, is difficult to get a good side to intercept intercept position.
intercept the initial segment, you need very advanced ballistic missile early warning radar and fire control radar, the current ballistic missile early warning radar technology to master and only the United States and Russia, other countries also can not be the first time found that signal incoming missiles. Even if the United States and Russia, it is difficult the first time from the vantage point of the enemy to intercept incoming missiles.
Beijing News: The United States is developing an airborne high-power laser weapon can intercept enemy missiles to achieve the initial segment. This program work?
Li Bin: The United States early in 1983 when Star Wars, had a dream to use high-power laser beams to intercept enemy missiles. These years, the U.S. has failed to address how to produce high-power laser beam and the expansion of laser heated air affect the two problems. For now, the use of lasers to intercept missiles do not fly.
middle of the block
Russia gradually left behind
Beijing News: the missile in flight outside the atmosphere and without outside influence, the middle block has what advantage?
Li Bin: ballistic missiles in the middle of the longest flight time and flight path is easy to measure, this stage should be the most suitable block. As the missiles outside the atmosphere flight from external influences, in order to improve the penetration performance of the missile, most of the attacking side will take counter-measures, which virtually increases the difficulty of interception.
Beijing News: What countries currently have the middle intercept test conducted?
Li Bin: the middle of the interceptor to intercept and monitor the performance of tracking the most demanding. According to public reports, only the United States, China has the ability to intercept the middle. U.S. Star Wars program as the only remaining fruit, the U.S. national missile defense program relies on ground-based interceptor “collision destruction” technology matures, the current constraints are mainly middle to intercept the missile detection and tracking capabilities. The former Soviet Union, Russia has been gradually in the middle block left behind.
Beijing News: How do the Chinese middle intercept test conducted?
Li Bin: test conditions and actual combat situation a huge difference, so the missile intercept test results are not representative of a national anti-missile combat level. China’s missile capacity, could form the middle of combat power, but also considering the political and technical level and industrial production capacity.
interception system varied
Beijing News: The missile re-entry from targets in close proximity, how to block?
Li Bin: Indeed, left to intercept the missile entered the atmosphere after the party time is limited, resulting in protection can block important regional parties. However, this stage of the interceptor to intercept the flight distance and accuracy is low, resulting in most countries for the intercept test is conducted in this phase.
Beijing News: Japan and India’s missile capabilities?
Li Bin: In addition to the United States and China, other countries, mainly by anti-aircraft missile interceptor upgrade from, the use of intercept debris attack mode. Although during the middle of this interceptor to intercept when the powerless, but still the end of the block. For location and to determine the main threats in support of the United States, Japan and Israel the end of the main interceptor technology development, Israel’s Arrow II interceptor system has achieved good results, Japan has developed a sea-and land-based interceptor system of double of short-range missiles have some interception capability. Although Russia in the middle block in the development of backward, but with S-400 system at the end is still in the lead position to intercept. The lack of missile detection and tracking capabilities, India’s missile interception capabilities are still many difficulties.
Israeli “Arrow -2″
mainly by the turquoise L-band early warning and fire control radar and the composition of the Arrow-2 missile, the missiles long 10.98 meter, two-stage solid rocket motors and high-energy fragmentation warhead and proximity fuze, killing radius of 50 meters, 10 times the maximum flight speed of sound, the maximum intercept range of 90 km, the maximum intercept altitude 40 km.
Israeli “Iron Dome”
mainly used to intercept a range of 5-70 km between the rockets and missiles. The system is equipped with six launchers, each launcher is equipped with 20 interceptor missiles. Only the price of its interceptor missiles, “Patriot” one per cent. It is reported that army will start deploying in 2010, will eventually deploy 12 units.
U.S. “Patriot -3″
used against tactical ballistic missiles, cruise missiles and advanced aircraft. Longest detection range of 400 kilometers, attack aircraft targets a range of over 100 km range missile attack up to 50 kilometers, will become the future U.S. land-based theater missile defense system’s main low-level interceptor.
China’s “red flag -9″
the outside world as the first China-made third-generation air defense missile. The missile destruction airspace large, anti-interference ability, advanced guidance system, a system-wide start time about 6 minutes, the reaction speed of 12-15 seconds, comparable to the Russian S-400 air defense missiles.
S-400 “Triumph” anti-missile system S-300 is based on research and development from its missile range of up to 400 kilometers, the range of most of today’s surface to air missile, the interceptor missile a distance of 50-60 km. The Russian military claimed, S-400 in speed, accuracy were better than the U.S. “Patriot PAC-3″ surface to air missile system, is the world’s best performing air defense missile system.
American “standard -3″
“SM-3″ missile is the Navy theater missile defense system, a high-level ballistic missile defense weapons can be launched from a ship. The missile length 6.55 m, a range of over 500 km, 160 km altitude interceptor. The United States has used the “standard 3″ missile successfully shot down the satellite out of control, which is considered the first real U.S. anti-missile system.
