It is 7 minutes to intercept the cruise missiles fired at the country's country. It was in this short 2 minutes that the killing weapon used by the Republic's Heavenly Army completely changed the outside world's understanding of strategic defense systems and also changed its understanding of defense tactics.

The full name of "Daoji" is "Regional Laser Intercept System".

It is very simple, but its meaning is not the same. Although in actual combat use, laser weapons can be focused on one point as people imagine, but form a relatively large spot, and the spot covers the target to achieve the goal of burning the target, among all kinds of energy weapons, laser weapons are still "point weapons." That is, they can only attack a certain target. When using a spectrometer, they can attack several targets at the same time, and cannot attack all targets within a region. The reason why laser weapons are difficult to become "face weapons. It is also very simple: the requirements for energy are too high.

In theory, laser weapons should have surface attack capabilities.

As we all know, laser weapons actually convert energy such as electrical energy, chemical energy, etc. into light energy, and then convert light energy into internal energy when attacking the target. In this way, as long as the output energy is large enough, the attack range can be expanded while ensuring the target is destroyed.

The problem is here. If you need to attack an area, the requirements for input and output energy will be quickly increased.

Because the area of ​​the spot is proportional to the square of the spot diameter, when expanding the attack range, the output energy of the laser weapon is proportional to the square of the spot diameter. For example, when attacking a ballistic missile, the diameter of the spot is about meters. If it is necessary to cover a rectangular area with a width of kilometers, the spot diameter needs to reach at least kilometers. The output energy of the laser will increase by 40,000 times, and the average output power is in the old clump power level. The peak output power is in the clear power level. Mom Yong doubts that such a high energy requirement, let alone those interceptor satellites that use composite batteries to supply points cannot meet the requirements. Even small controllable fusion reactors are difficult to meet the requirements. With the technology of the mid-century, only with the State Grid as the backing, this energy standard can be achieved.

Now, the problem is very obvious.

As we all know, the State Grid belongs to the most basic infrastructure. As for the Republic's State Grid, starting from the year of the year, under the influence of the power revolution, the Republic's authorities have designated the establishment of a new national backbone power grid as one of the basic projects for industrial structure adjustment, and aim to adapt to the future development needs of the field year. The transformation project has gone through three generations. It has been lasting for the recent years, and it was not completed until the year of the milk year, and the total investment in the project is nearly one trillion yuan. Relatively speaking, compared with the huge project investment, the long engineering cycle is more unacceptable. It can be said that even if the load load of the Republic's State Grid is as high as the old mutual power kilowatts, and the peak load capacity is as high as 0,0 flying power kilowatts, which can basically meet the requirements of regional laser weapons for input power, but the negative impact is difficult to estimate.

It is precisely this that laser weapons have not become "weapons of destruction".

To be precise, before the Tian era, the development of laser weapons into weapons of mass destruction with regional strike capabilities has been at the theoretical research stage, without specific implementation, and no relevant experiments were even conducted.

The problem is that pursuing greater power is always the development direction of weapon systems.

Against the backdrop of a comprehensive arms race, any kind of discourse can happen.

In fact, making laser weapons have regional strike capabilities originated from a research topic that intercepts cruise missiles. As early as the early days of the geography, the technology of using phase interference to generate virtual images was made major breakthroughs. A large number of weapons and equipment with powerful deception functions, such as virtual imagers, were launched one after another, and the interception ability of the strategic defense system encountered a huge test. At that time, the Republican authorities set up a research team in the name of theoretical research at the Center for Physical Experiments, that is, when encountering a large number of virtual images, what methods can be used to ensure the most effective local security. The conclusion of the theoretical research is that all targets are intercepted regardless of true or false, and all

Only by causing fatal damage can local safety be ensured. There is only one way to achieve this goal, that is, to release huge energy on the target path and destroy all man-made objects. Among the suggestions given by the research team at that time, the most important thing was not the laser-based energy weapon system. Instead, it was to directly throw nuclear warheads into the target area and use nuclear explosion to destroy incoming missiles. Mu Yong suspected that this interception method must be very effective, but the collateral damage is also very large, and it is impossible to be adopted by the Republic authorities. Not to mention, if the incoming missile has entered the Republic's airspace, using this method is equivalent to bombing the country's territory with nuclear weapons.

It was under this premise that the Republic authorities launched this secret project within the "Yanhuang Site" project.

The specific time for the movement should be around Li Qiaonian. The person in charge at that time was Pei Chengyi, who had already served as Minister of National Defense.

Like other new concept weapons that require huge investment, the "regional laser interception system" has undergone feasibility study for several years after its establishment. There is no doubt that the research results are not only "feasible." and also of great significance, otherwise there would be no actual combat performances from many years later. Because it is an integral part of the national strategic defense system and one of the most important components. Therefore, the "regional laser interception system has entered the engineering development stage, and referred to other top-secret projects, and was managed by the Military Intelligence Bureau. It was not allowed to intervene with the Ministry of National Defense. According to the records of the Military Intelligence Bureau, the engineering development was officially launched at about 2 cakes.

In principle, the biggest problem of the entire system is how to obtain huge energy.

To be precise, how to obtain huge input power. If you rely entirely on the State Grid, even if you calculate it based on the average output power, and the energy conversion efficiency is, the State Grid will operate in a peak state, which will occupy about 10% of the State Grid's transmission capacity, which will have a serious impact on social electricity use. Because the energy conversion efficiency cannot be achieved, the ship will ideally degenerate, and the State Grid will not operate in a peak state at any time. If it is started urgently, it will definitely take a lot of time and cannot meet the minimum standard of tactical reaction. In actual use, it is very likely to occupy the transmission capacity above the State Grid, thereby crushing the State Grid. Or paralyzing other social systems will definitely exceed the scope of tolerance.

Of course, the solution is not without it, it is just expensive.

The most feasible solution is to store some electricity in peacetime based on the maximum output energy, and reduce the pressure on the state power grid by connecting to the grid when using it. If half of the electricity required for war can be stored, the pressure on the state power grid can be reduced by half, and the occupancy rate will be reduced from the account to the gills. In conjunction with the wartime system, and some civil systems also have backup power supplies, the impact can be controlled within the minimum range.

As mentioned earlier, this would be extremely expensive.

Taking the interceptor and the Lianmei hypersonic cruise missiles launched by the bomber as an example, even if this is the bomber launches missiles at the same frequency, and the replacement missiles are divided into batches, with the interval between each missile being four meters, and the interval between each batch of missiles being kilometers. All of them must be destroyed by regional interception. The laser beam falling in the target area must have at least 0 meters in diameter, and the action time must not be lower than illusory. The total output energy is as high as the old joules. In actual combat, various unexpected situations must be considered. Therefore, the diameter of the light spot needs to be expanded by the old times, and the continuous action time needs to be extended to at least illusory. Therefore, the total output energy will be as high as the old joules by the old power.

Mo Yong doubted that this is a very quiet number.

You should know that at the level of past years, all controllable fusion nuclear power plants in the Republic operate at maximum power together, and they also need to hold a meal to work for an hour to generate so much energy. If calculated based on the redundant power generation in peacetime, half of the electricity will be stored for only one interception and storage.

That is why the first work in the system engineering stage is to build electrical energy storage facilities.

This is what mentioned earlier, the secret military base located in the Taihang Mountains. This one has only one number in the documents of the Ministry of Defense of the Republic. The military base without a name has stored a total of 8-level recycled and below level 8 and below composite batteries, and all composite batteries are fully filled with electricity. Of course, for safety reasons, all composite batteries have been inspected before charging, eliminating the potential for failure, and are controlled by a central computer. When encountering danger, trace metal hydrogen inside will be automatically released to avoid explosions. Even so, the 10,000-ton composite batteries with scattered storage will also fill up three peaks.

Of course, because all storage locations are four meters below the table, from the surface, there is no abnormality between these three peaks.

It seems that this is a huge military base.

In order to fully charge this 10,000 tons of composite battery, it took 4 years. The 10,000 tons of composite battery is enough to allow all factories in the Republic to run for 6 months day and night. Such huge electricity can only allow the intercepting system to work in a standard mode 6 times.

Obviously, this is not enough to ensure the strategic security of the Republic. After the second phase of the London Treaty was completed, the strategic bombers maintained by Russia alone could carry out eight large-scale attacks on the Republic, while the strategic bombers maintained by the United States could carry out large-scale attacks on the Republic. In this way, the entire interception system must be built according to the standards of continuous work. Therefore, in Changbai Mountain in the northeast of the Republic, Tianshan Mountain in the northwest and Wuyi Mountain in the southeast, each with a similar scale, storage of scrapped composite batteries ranging from 80,000 tons to 10,000 tons. Moreover, the composite batteries in these bases were all completed at the beginning of the year.

I have to say that looking at the whole world, I am afraid that only the Republic has such strength.

You should know that Heguo is not only the world's largest composite battery manufacturer, but also issued relevant laws for recycling all composite batteries in four years. The cost of destroying scrapped composite batteries is relatively high, and the cheapest way to destroy is to naturally attenuate the metal hydrogen in the composite battery. Over the past few decades, at least millions of tons of scrapped composite batteries have been stored in the Republic. Because the nominal service life of any industrial product is lower than the actual service life, it will leave redundancy, so many scrapped composite batteries can still be used, but their performance does not meet the design indicators. Apart from the earliest mass-produced level 2 and 4 composite batteries, other composite batteries that were scrapped and stored after the Jiangnian year were broken, so that about 10,000 tons of recycled composite batteries were stored in the base.

It can be said that if these composite batteries were not available, the "regional laser interception system" was still in the theoretical research stage. The reason is very simple. Even if the price of composite batteries is not considered, if the price of composite batteries is replaced by a multi-ton port-level composite battery, the procurement price is as high as one trillion yuan, which completely exceeds the national affordability. The production of composite batteries and the problems caused by the large-scale expansion of production must be considered.

Solving the energy problem does not mean that other problems no longer exist.

After obtaining enough energy, how to project energy to the target has become a new problem.

This problem is divided into two parts: one is the power of the laser and the other is the energy transfer.

The former is relatively easy to solve. Even if one laser cannot output all the energy, it can also be used to connect multiple lasers in parallel to output all the energy. Of course, there are many problems that need to be solved, such as how to ensure that all lasers inputted by lasers have the same phase. If the phases are different, the power will be attenuated, and how to make all lasers have the same directionality. Of course, these are technical problems, not basic conditions, and can be solved through reasonable design and clever technical means. For example, by using an adaptive reflector equipped with a negative feedback system, the laser beams emitted by each laser can have the same directionality.

Of course, the focus is on the second issue.

Mu Yong doubted that the old ten thousand tons of composite batteries and basic energy design based on the State Grid should be placed on the ground. As we all know, the surface of the earth has amplitude. When irradiating low-altitude targets, the laser's action distance is very limited. Even if the laser is placed on Mount Everest at an altitude of altitude, the attack distance of the target on the sea level is within 4,000 meters. In this way, reflection can only be used to emit high-energy lasers thousands of kilometers away. It is precisely this way that there will be a special reflective satellite above the geosynchronous orbit.

Because the entire system is under absolute protection, before it is officially put into use, the outside world was not aware of it. Even the commander of the Heavenly Army of the Republic did not know that there was such a powerful interception system, so the reflective satellite was launched in the name of communication satellites, and the reflective mirrors used the latest technology and materials. Of course, the "latest" here does not refer to the high-strength memory alloy that builds the mirror skeleton, but the adaptive intelligent fiber fabric that forms the mirror.

The biggest feature of this imitation fabric that sounds like a cloth is that it can automatically adjust the surface curvature of the fiber according to the change of light pressure, so that the light always reflects in a fixed direction. That is to say, as long as the orientation of the skeleton is adjusted, no matter what the reflective surface looks like, the laser beam illuminated on it will be reflected in the same direction.

This characteristic may not be useful in the ground. It is particularly useful in outer space where temperature changes are huge. You should know that any material has the properties of thermal expansion and contraction. When the reflection distance reaches 4,000 meters, even very weak changes will fail to focus, resulting in energy dispersion, unable to reach the level of burning targets, and completely failing the attack. More importantly, in outer space, if there is no ability to automatically adjust according to environmental changes, any mechanical control method cannot ensure high enough accuracy.

According to the development list of the Military Intelligence Bureau, in order to develop this fabric, scientific research alone cost more than 400 million yuan.

Of course, this kind of fabric is not perfect. Because it automatically adjusts the surface curvature of the fiber, the reflectivity of the laser is far inferior to that of the metal mirror. The average emissivity is only the emissivity of the left and right metal mirrors. Although the gap is too large, this means that among the emitted light energy, about strong light energy will be converted into internal energy, radiation energy and other energy on the surface of the reflector, and the absolute majority of them is internal energy. Even fabric fibers can change according to temperature.

To adjust the surface curvature to ensure that the emission direction does not change, but if you don’t find a way to dissipate the heat generated by laser irradiation, the reflective mirror will definitely be burned. This is why behind the reflective mirror is a highly conductive thermal coating with a thickness of close to Jumi, that is, the excess internal energy is taken away by evaporating the heat-sensitive coating. Even so, the entire reflective mirror can only work continuously for seconds at most, or work in an intermittent manner. If each irradiation is continuous and insignificant, it will work at most 8 times.

That's true, in the geosynchronous orbit above the equator, there are 3 of these reflective satellites in total.

Usually, these six satellites are in a convergent state, and they will convert electromagnetic signals like communication satellites to avoid suspicion from the enemy country. Only when working, reflective mirrors will be unfolded. What's bad is that reflective mirrors can only be unfolded and cannot be retracted. In other words, each satellite can only work once and does not have the ability to repetitive work, which is why three backup satellites need to be prepared.

Anyway, this is an epoch-making weapon, an absolutely devastating weapon!,
