Currently, Japan's security environment is in a very difficult situation.
If there is a war, the first thing that will be done is a saturation attack with missiles.
* The number of missiles that cannot be dealt with is large.
In the US Department of Defense's annual report on military and security progress involving the People's Republic of China, etc.
China has more than 2000 ballistic missiles capable of attacking Japan
, and it is said that there are more than 120 launch facilities.
On October 17, this year, the US Department of Defense announced that "China has succeeded in testing a new missile," which is different from Russia's Avangard.

According to media reports, hypersonic missiles orbit the earth and fly from behind.
* Hypersonic = Mach 5 or higher, Hypersonic = Mach 1 or higher
The name of this missile is
FOBS: Fractional Orbital Bombardment System, which is a
"partial orbital bombing system" in Japanese.
Something like a spaceship in low earth orbit (launching a missile platform) orbiting it and launching missiles at any time.
That is, in theory, it can be an attack system from space.
(Probably, launching an offensive weapon that orbits in orbit is prohibited by the treaty, so it is considered as a partial orbit.)
The Self-Defense Forces cannot respond to what even the current US military cannot respond to, and it will be difficult to continue intercepting even conventional missile weapons in the first place.
How useful is the current Japanese missile defense network?
As stated in the Defense of Japan, the Air Self-Defense Force currently owns about 100 Petriots, and I don't know how many missiles there are, but if there are eight missiles, a maximum of 800 can be intercepted.
The JMSDF is said to purchase 180 SM3s from rice, including existing ones.
In other words, there are about 1000 interceptor missiles of the Japan Air S
elf-Defense Force for every 1000 missiles in China.
On the other hand, according to US experiments, the US military's missile interception rate is about 83% when one interception missile is fired for each missile.
Therefore, if 1000 shots are hit, 200 shots are expected to land.
Most of the 200 shots should fall to air bases, SDF headquarters, the Ministry of Defense, etc.
By the way, there was a senior who was an acquaintance of my senior self-defense official who had calculated the physical power of intercontinental ballistic missiles (no explosion, F = ma only) and submitted a dissertation, but the concrete penetration ability is 15 m. It was over. (Because of the hardness of the warhead, the power is less than this)
Considering that even the US military GBU28 (bunker buster), which simply falls and explodes, penetrates 6 m in thickness, ballistic missiles may have destructive power to penetrate 10 m or more.
In other words, if an ICBM collides, all buildings, including underground facilities, will disappear. (The current ICBM is very accurate and the landing error is less than 100m)
How many facilities have a concrete thickness of 10 m or more in Japan's political economy center and the headquarters of the Self-Defense Forces?
Once the battle begins,
First of all, the official residence (including US military bases), the Di
et, Ichigaya, 17 SDF headquarters, 27 ASDF radar sites, 7 major runways, 7 major bases with fighter aircraft, and 5 major ports of the JMSDF. I think it will be a goal and many of them will be destroyed.
