On September 10, former Internal Affairs and Communications Minister Sanae Takaichi, who announced her candidacy for the LDP presidential election, said in a TV Asahi program that ``neutralize enemy bases with electromagnetic waves'' in relation to the enemy base attack theory. I spoke. It refers to EMP (electromagnetic pulse) attacks.
However, the first conclusion is that it is almost ineffective against North Korea's ballistic missiles, which is an urgent issue. North Korea's ballistic missiles are mobile launchers, and just before the war, they sortie from the base and hide their whereabouts. There is no point in neutralizing the base. In that case, it is necessary to find a mobile launcher and shoot EMP bullets nearby, but the problem of finding the target itself is extremely difficult.
EMP bullets, which use conventional explosives to compress magnetic flux and generate electromagnetic pulses, have such a wide effective range. not. I don't know if it's accurate because there are many secrets, but if the radius is from a few dozen meters to a few hundred meters at most, it would be useless to attack unless you know the target's location to some extent.
Originally, the EMP bullet was a weapon intended to eliminate enemy targets in a group of locations whose whereabouts are known. As a result, mobile ballistic missile launchers that spread out and hide while running away after sortieing from the base are quite incompatible opponents to target with EMP bullets.
In the first place, I don't know how effective EMP bullets are against mobile ballistic missile launchers before they are launched. Since the target of the EMP shell is originally the electronic circuit such as the active radar and communication system, there is a possibility that the missile in the non-activated state will not have a satisfactory effect.
Although it is a little different from electromagnetic attacks, radio jamming has almost no effect against ballistic missiles.
In the past, there was only one example of an electromagnetic wave attack that was effective against ballistic missiles. Cold War-era ABMs (anti-ballistic missiles) are interceptor missiles with nuclear warheads that detonate in close proximity to incoming enemy ballistic missiles, destroying and neutralizing the target's electronic circuits with powerful radiation (a type of electromagnetic wave). .
Conversely, this means that in order to neutralize a ballistic missile with electromagnetic waves, even the radiation from a nuclear explosion must be done from close range.
* ABM: American surface-to-air missiles "Nike Zeus" and "Sprint", Soviet/Russian surface-to-air missiles "51T6" and "53T6".
In fact, the Ministry of Defense of Japan has been researching EMP bullets for electromagnetic attacks that compress the magnetic flux using conventional explosives for some time. However, the current research has become difficult to continue due to problems with parts procurement, and is scheduled to be restarted immediately after being suspended.
In the operation concept diagram, it is assumed that they will shoot near the enemy forces that have landed on the island. As you can see, the area of effect is not large enough to cover the entire theater. Still, it is a weapon that can affect a wider range than normal bombs and missiles.
As the purpose of the EMP bullet is to "neutralize the enemy's sensor and information system", it aims to neutralize the radar and communication system. The aim is to crush the enemy's eyes and ears, but if the enemy repairs it or prepares alternative equipment, it will be revived. It will be used to confuse the enemy and temporarily buy time to hit the favorite direct attack.
EMP ammunition is not an all-purpose weapon that can neutralize the enemy, but rather it will be a support equipment for sabotage.
