Japan and north Korea the satellite happen "dispute", the surface with China seems to see not have too big relationship. But in fact Japan this move, proved the military alliance of joint antimissile system has been under pushed China's doorstep.
The United States is the world's most advanced countries anti-missile technology, the foundation has spent the interceptors deployed, just testing experiment is not ideal. From the Obama administration in place, the cost, the technology is complex and mobility of anti-missile technology foundation difference from left out in the cold,
and with standard-3 missile's interceptors on aegis and as a representative of the sea-based missile defense systems, with its flexible deployment of the way to get the favour of top of the American military. Will the United States itself test results to see, the success rate is much higher than the technology of the complex foundation interceptor missiles. In 2008, the United States using standard-3 missile shot down out of control U.S. spy satellite, more proved the advantages of anti-missile system heikki.
In 1998, north Korea launched a missile over Japan after, shook up and down Japan. Since then, although Japan is not missile technology power, but rely on japan-us military alliance, to establish in the basis of heikki's interceptors on aegis antimissile system spare no effort. So far, Japan's four craft level's interceptors on aegis destroyers king kong, all above standard-3 missile launch to intercept tests, and has obtained the success. In addition, Japan's new to the construction of the two ship "love is down" class's interceptors on aegis destroyers, and will likely have standard-3 missile launch of ability.
Japan's defense target, is the future has 5 ship has the ability of the missile destroyer. And the United States in 2010 that have 5 cruiser and 16 destroyers compared with abm capability, the number of Japanese seem to nothing. But can't ignore, Japan now has the world's second and Asia first sea abm strength. And the ground-based interceptor different, destroyers carry the antimissile missile cruising in the ocean on, have a lot of mobility, can make up for the range and large foundation antimissile missile gap.
500 miles (kilometers) attack can be implemented
Standard-three missiles have been developed out of the four "variant". The first standard-three Block I was in the original standard-2 with a third on a rocket engine, new guidance system and the kinetic energy killer warheads. The follow-up of standard-3 Ⅱ Block, the body diameter bold, range farther, better able to intercept. Due to the standard-3 combat range up to 500 kilometers, this means that the Japanese ships in the opponent's territorial waters besides, can launch intercept missiles.
To the north Korea launch rockets, for example, Japanese media calculation if north Korea rocket failure, Japan's naval ships on the high seas in 500 km north Korea's rocket highly intercept. 500 miles is a very alarming number of, this is the outer atmosphere, very close to the universe. In 2008 the United States shot down the height of the satellite is 247 kilometers. Of course we can questioned whether Japan has the ability to achieve this highly interception, after all the interception of test and actual combat general and not matter, but in battlefield surveillance system developed and 200 km to the thin atmosphere, equipped with miniaturization kinetic energy warheads-3 standard interceptor missiles in higher height also has the ability to intercept a single target.
