Beijing time at 115, a strategic alarm sounded.

The two sets of alarm systems of the "Strategic Early Warning System" and the "tactical warning system" targeting Japan send out strategic attack signals almost at the same time. The information is transmitted to the "Strategic Defense Command Center" of the General Staff at the speed of light, and the "Regional Strategic Defense Operation Center" deployed in the northeast and southeast regions. According to the combat plan, the combat orders were quickly issued to the combat troops. About 15, the "national strategic defense system" of the Republic entered a combat state. After about 15, the "strategic strike force" of the Republic entered a combat state.

Wang Yuanqing took the underground rail transit system as soon as possible and went to the strategic command center in the suburbs from the General Staff.

At the same time, the Ministry of National Security Special Operations Force, which is responsible for the safety of leaders, picked up dozens of senior national leaders to a "strategic shelter" in the suburbs in accordance with the combat plan.

Within 2 minutes, the state institutions of the Republic entered a state of total war.

When encountering the "highest threat", under the control of the strategic operating mechanism, various actions are carried out in an orderly manner.

For Wang Yuanqing and others, this has a tendency to be "practical drills".

The war operation mechanism of the Republic is not directed at Japan, but at nuclear powers such as the United States and Russia that can completely destroy the Republic. To be precise, it is against global nuclear war. The core task of this mechanism is to ensure the security of the leaders of the Republic when a sudden nuclear strike is encountered. The highest military commander of the Republic (usually the head of state. If the head of state is killed, the highest national leader will be determined in the order of the deputy head of state, the chairman of the whole congress, the Premier of the State Council, and the chairman of the consultation meeting) will issue a strategic counterattack order.

This is not a strategic operating mechanism that only the Republic has. Any nuclear power has a similar mechanism.

The United States is an example. If the United States is subjected to a sudden nuclear attack, it is enough to send the president to Andrews Air Force Base (in Washington) within 2, the Air Force One can take off within 5 minutes. Senior leaders such as the Vice President, House Speaker, Secretary of State, etc. evacuate through other channels to ensure that at least one leader can escape the nuclear attack and issue a strategic counterattack order after the local attack is hit.

To ensure the effectiveness of the strategic operating mechanism, relevant exercises will be conducted every year.

The most important thing about this is how to intercept Japanese ground ballistic missiles.

If you want to intercept ballistic missiles, you must discover ballistic missiles.

Even if an intercontinental ballistic missile with a range of more than 1 kilometer can hit the target within 20 minutes. An intermediate-range ballistic missile with a range of less than 5,000 meters can hit the target within 1 c minutes.

It is also said that the entire process from discovery to shooting down missiles and even launching a strategic counterattack is only a few minutes.

In this way, how to discover and confirm whether the enemy launches missiles in a timely and effective manner has become the top priority.

To this end, all nuclear powers have established a "strategic early warning system".

The "strategic warning system" mainly consists of two types of alarm systems, one is a strategic warning satellite equipped with a wide-area infrared/ultraviolet detection system, and the other is a strategic warning radar with a detection distance of thousands of kilometers.

Strategic early warning satellites are not affected by the Earth's curvature, have a wide detection range, and are timely discovered. They can roughly locate the target, but they have disadvantages such as not being able to accurately identify the target, accurately locate the target, and unable to measure the target's flight ballistics. Strategic early warning radars are deployed on the ground, limited by the Earth's curvature, and have limited detection range and high false alarm rates, so they cannot detect the target in time. However, they can identify the target, accurately locate the target, and measure the target's flight ballistics.

A perfect "strategic warning system" requires effective cooperation between two systems.

Generally speaking, a brief warning satellite first issues an alarm, and then a strategic warning radar tracks and locates the target.

Because Japan is too close to the Republic, both systems can play a role.

In order to measure the target flight trajectory more accurately, compensation is also needed through a "tactical alert system".

The "tactical alert system" is generally a large aircraft carrying long-range detection radar and high-precision optical instruments. It has similar combat properties to the KZ-119. It patrols the airspace near the enemy country and can promptly detect ballistic missiles launched within a range of hundreds of kilometers or even thousands of kilometers.

The Republic's "tactical alert system" is the zs-1cc type remote alert machine with the y--15b transport aircraft as the carrier.

After the war began, at least zs-1c patrols over the Japanese sea, and 2zs-1 patrols over the East China Sea. When the flight altitude is 15,000 meters, the long-range detection radar it carries can detect ballistic missiles 1,200 kilometers away, and the high-precision optical detector can accurately locate missiles within 8c0 kilometers, and roughly calculate the missile's attack area based on the missile's launch trajectory. Using high-capacity tactical data links, zs-1cc can send the obtained tactical information to nearby interceptor units at the fastest speed.

In the battle process of defending ballistic missiles, time is everything.

ZS-1cc discovered 12 ballistic missiles that took off, and the relevant data was immediately sent to the "air-based laser interception system" that was also carrying out combat readiness patrol missions over Japan. To be precise, it was a DL-1b laser interception weapon system carrier.

DL-1b still uses the Y-15 as the carrier, and its main combat equipment is a set of "100 MW free electronic electrical energy laser". The peak output power of the laser exceeds 180 MW, which is 8

The battery is used as a direct power supply, 24~: The composite battery and two transformers are used as backup power supplies. If necessary, the 8-level composite battery that provides flight power to the carrier can also provide the laser with an 8-level composite battery that provides flight power to the carrier. Without using the carrier power, the target can be dealt with in the first round of interception and another target after 15 minutes. The auxiliary equipment is a "same-band indication laser", a set of high-precision phased array positioning radar installed on the left and right sides of the front fuselage of the carrier, and a set of safe

The infrared/ultraviolet optical detection system installed above the cockpit of the head of the carrier, a laser data collection system, a long-range meteorological radar installed at the tail of the carrier, and dozens of communication and information processing systems. The core of the entire combat system is a neural network computer with a computing power of tens of trillions of times per second, and an electronic computer as a backup system. Mainly, meteorological radar requires extremely powerful computing power to be equipped with expensive neural network computers.

It can be said that the powerful information processing capabilities are the fundamental difference between dl-1b and dl-11a.

After receiving the tactical information of zs-1cc, dl--1b immediately enters the combat state.

First, the positioning radar roughly locates the target, the optical detection system collects the radiation characteristics of the target, determines the laser irradiation point, and then the meteorological radar collects the meteorological data of the "light path" to determine the required irradiation power and irradiation angle; before the main battle laser is started, the laser is instructed to irradiate the target, and the laser data collection system analyzes the reflected laser to confirm the accuracy of the laser irradiation point; after confirming that the irradiation point is completely consistent, the main battle laser is started, and a high-energy laser beam is fired to the target, and the high temperature generated by laser focus is used to burn through the missile body, causing the missile to deviate from the flight trajectory or destroy the missile's warhead and propulsion engine to achieve the purpose of destroying the missile.

When the missile is in the boosting stage, it mainly illuminates the missile's propulsion fuel section and destroys the missile's propulsion system.

It seems that this operation process is very complicated; in fact, it is not complicated in combat use, and the entire combat process is calculated in milliseconds.

After only 15, 5dl-1b, which performed combat readiness missions on the first patrol, launched an attack.

About 5 years later, 2dl-1b, which was carried out combat readiness missions in the northern airspace of the second patrol point, was put into combat.

When the first high-energy laser hit the solid fuel section of the x-2 ballistic missile that first took off, it was only 25 away from the Japanese missile launching!

The time-bomb is still in the vertical rising stage.

That is to say, the x-2 ballistic missile still leaves the atmosphere above Japan!

Because only 12 targets were intercepted, each DL-1bb only needed to intercept twice, and the commanders on the D1b chose the maximum launch power. At that time, the sky was clear over the Japanese sea and the weather conditions were "optimal". In this case, it only took 7 seconds to continuously illuminate the missile body and ignite the solid fuel inside!

When intercepting the first target, all dl-1bs participating in the battle use tactical data links to exchange interception information, and use an instruction laser to track the second target to prepare for a second interception. That is to say, after shooting down the first target, you only need to wait for about 8 to intercept the second target.

At this time, another five x-2 missiles have reached the top of the atmosphere and are about to enter the middle section of the ballistic.

Although at the beginning, the "air-based laser interception system" only targets targets in the atmosphere, when the second phase of the construction of the "National Strategic Defense System", dl-1b had the combat capability to intercept targets outside the atmosphere. In previous exercises and tests, the interception capability of dl1b was also proved. As long as the instructing laser can continuously illuminate the target, the main combat laser can be guided to illuminate the target through the laser data collection system. Because outer space will not have an attenuation effect on the laser, the combat efficiency when intercepting outer space targets is higher. Of course, the prerequisite is that the indicator laser must be used to continuously illuminate the target, because the positioning radar works in the x-band and cannot penetrate the ionosphere at the top of the atmosphere, and the optical detection system is also easily disturbed.

As the main battle laser turned, the five x-2 missiles that had just flew out of the atmosphere were shot down one after another.

Unlike the first batch of x-2 missiles that were intercepted, these five missiles had already left the sky above Japan when they were shot down, and when they returned to the atmosphere, they disintegrated and burned in the air due to the damage of the heat shield.

Sadashi Murakami, who issued a counterattack order, did not expect that he shot himself in the foot.

Seven x-2 missiles shot down over Japan were burning and exploded when they fell. Although the nuclear warhead was heavily protected, and its inertial fuses into the atmosphere would not detonate the nuclear warhead due to the missile crash, when the warhead landed in the northern part of Honshu Island in Japan at a speed of more than 2,000 meters per second, it would not only fall to pieces, but also burn to produce a high temperature of thousands of degrees Celsius. After the warhead shattered, the high temperature was enough to evaporate the concentrated inside. Instead, it is known that the substance with the most poisonous substance can poison the whole world 70 grams! Even if the toxicity is not considered, radioactivity must be considered. In other words, the area where the warhead crashed has become a "no man's land."

For Japan, which has a small land area, this is undoubtedly the biggest disaster. (To be continued,)
