The key points of "Missile Defense Review" announced by the U.S. Army

　On January 17, the United States Pentagon announced a missile defense review (MDR).Originally, it was scheduled to be announced a year ago, but the presentation was delayed to include not only ballistic missiles but also extremely ultrasonic glide missiles.However, the announced content did not seem to urgently take measures against extreme -speed gliding missiles, and first of all, the focus was on deploying a sensor for finding a goal and tracking.

Measures against extreme superior glide weapons (HGV)

　It was a countermeasure against extreme ultra -sound -speed glide weapons (HGV), which is considered to be practical in Russia and China, which was attracting attention for this MDR, but HGV is less handled when read the contents of the actual report.As a countermeasure, there is no rush to develop a new interceptor missile, and it is characterized by the fact that the construction of a sensor network that tracks and tracks the goal is first.HGV, unlike ballistic missiles, can repeat the horizontal variable on the horizontal surface, making it difficult to predict the location.Therefore, it is important to place many sensors in outer space, find them early, track them, and keep grasping the movement at all times.

　The fact that the United States is not in a hurry against HGV is that missile defense is intended to compete against North Korea and Iran, and does not oppose Russia or China.There is a policy of responding to the latter by nuclear deterrent, which is still maintained.In terms and quantities of the GBI, the Defense Missile for Defense Mainland, which is scheduled by the current situation and the near future, Russia and China are sufficiently broken through the existing intercontinental ballistic missiles (ICBM) without having to take them out.Is possible.In other words, missile defense is not yet a loss of nuclear deterrence.

　The HGV developed by Russia and China is actually unnecessary weapons at present.This can be considered a trump card that the United States can respond to the balance of nuclear deterrence by changing the policy in the future and defending a nuclear deterrence.And although the United States did not intend to change the conventional policy, it has begun to prepare a way to counter the opponent's trump card in the future.In other words, both sides are trying to prepare new weapons just in case.Therefore, it is not an urgent project, so I am not in a hurry.

Multi -warhead interceptor mokv

　In fact, the development plan of the multi -warhead interceptor "MOKV" introduced in this MDR can be a balance of nuclear deterrence.When an enemy ballistic missile is multi -rounded, it is a plans for a multi -bulleting of an interceptor missile, and is a plan for a power that is equipped with a large number of interceptors in an interceptor missile.

　This is not a North Korean countermeasure but a countermeasure against Iran, and Iran has already achieved multi -warhead (MIRV) of ballistic missiles.However, Iran voluntarily regulates that it does not develop a ballistic missile with a range of 2000 km or more that can hit Western Europe directly to maintain international relations with Europe and the United States.However, in the future, if Iran decides due to the change in international situation, it is certain that long -range ballistic missiles will be developed and multi -rounded technologies will be combined.For this reason, the United States has no choice but to take a policy to compete with mokv.However, if all the GBI warheads are mokv, they may be able to compete with Russia and China ICBM.

　If North Korea and Iran continue to develop ballistic missile technology, if they are caught by it and continued to develop countermeasures, such a future will come someday.If you do not stop it somewhere, it will affect the balance of nuclear deterrence between the great powers.

Boost phase intercept

　Another highlight of the MDR is to shoot down a laser cannon on an unmanned attack aircraft for a boost phase intercept that a ballistic missile aims at the acceleration.

　There are also referring to the F-35 fighters for the boost phase intercept, but it is a specific weapon name whether it is a support purpose to detect it with an infrared sensor or a weapon to attack.There was no detailed mention.In the past, the U.S. military has not been officially adopted while planning a fighter -equipped missile for a boost phase interception called "NCADE".This is not the name, but it may be resurrected.

　The U.S. Army has devised several ways in the past in the Boost Phase intercept, and some have succeeded in shooting.However, it was judged that it was not practical, and the last remaining method was "The unmanned attack aircraft boarded the unmanned attack aircraft over the enemy country, surveillance, and the unmanned attack aircraft that was gradually fired nearby.It is a method of shooting a laser gun.It is impossible to find a ballistic missile moving launcher that runs away while hiding and hunt by air bombing, so it is an idea to find it and shoot down in a flashy injection inflammation immediately after firing.In other words, it would be more correct to recognize this as a direct alternative means of bombing rather than intercept.

　The premise of continuing to monitor a huge number of unmanned attack aircraft over the enemy country is required to first conduct full -scale and full air bombing operations by a manned attack aircraft and fully control the enemy air network.increase.You must eliminate all enemy fighters and earth -to -air missiles.This is the only U.S. army in this world that can carry out this in the first time in a short period of time.It would not be possible to achieve it without a considerable difference in ability, so North Korea and Iran were assumed, and there was no boost phase intercept for Russia and China, which owned powerful force.Become.
