Sakura Airport, the largest airport in China outside the sea, is now busy. Even if the plane takes off after an hour, the necessary preparations have already begun in two hours. To ensure the plane takes off quickly and smoothly, some preliminary work is also being carried out in advance. Now all the planes have appeared on the tarmac, with at least more than 200 vehicles of all sizes and sizes, and are loading supplies tightly.

Because it is airdrop, it is not a bulk packaging, but divided into about 500 kilograms. It cannot be too big, and it will be difficult to airborne. These materials that have been packaged will be delivered to the plane little by little through conveyor belts. More than 1,000 tons of materials are only needed to load the plane. As for the airdrop process after loading, it is much easier. The transport aircraft specially prepared for airdrops have special guide rails. Not to mention 500 kilograms, even one or two thousand kilograms can be quickly airdropped.

The Sakura Airport runway is temporary and can be temporarily enabled. China is not going to strengthen it on the original basis, but there is no discount on the construction of the entire airport's auxiliary equipment. Whether it is a semi-submersible underground hangar or an underground oil depot, all of them are built with high standards. The thickness of the standard reinforced concrete is required to be 7 meters, which is definitely not 6 meters.

The high indicators of these places are, on the one hand, because of China's regulations, and on the other hand, because these are the most easily attacked targets. Not to mention air strikes, in this era, other countries do not have enough powerful air force to threaten China, but without air strikes, it does not mean that other attack methods are not allowed. At least artillery is still OK.

China attaches great importance to this strategic base. In history, there are many strong combat power airports, but there are no opponents around, but they are sneak attacked by the army. The reason for choosing this Sakura Airport is not just a reconnaissance aircraft airport. The advantage of geographical advantage occupies a large part. However, no matter how the outer defense line is arranged, it is enough to deal with a huge part of the infantry, but it does not include artillery. The infantry of the two divisions plus heavy firepower can control a range of up to 5 kilometers, 5 to 20 kilometers, which is only beneficial, not absolutely avoidable.

The range of artillery is divided into effective range and maximum range. The effective range is both powerful and accurate, but the maximum range is far beyond the effective range. Some artillery with an effective range of 10 kilometers have a maximum range of even more than 30 kilometers. After all, according to the principles of mechanics and some means of borrowing force, the shells can fly far. Of course, for this 30 kilometers, the target is basically not found, and the deviation is at least more than 3 kilometers. This has no effect on combat.

But if you can fight, you can fight. Are there few coincidences in history? Isn’t there a report that a senior officer’s wife was shot while shopping for groceries and was caught by the public’s calves. At that time, it was a spy or a murder. In short, not only did the local public security bureau take action, but even the military and Guoan were secretly investigating, seeing who attacked the lover of this senior officer.

It has to be said that the state machine is powerful, in less than three days, but the result is ridiculous. Bullets are the best physical evidence. A little checked, because there is no demonstration of the bullet, not self-made, but standard. After some analysis, even those who shot out of that gun were known. Finally, when investigating the gun, it was found that the gun had been in the military camp and was not loaned out. It was just used by the training troops to shoot targets that afternoon, and in terms of time, it was about the same time as the time when this lady was attacked.

The first result came out. Everyone was stunned. The target shooting site was several kilometers away from the site where the lady was attacked. At that time, the Type 56, let alone a few kilometers, was difficult to exceed one kilometer. The range of 56 and a half was at most about 400 meters, and the target shooting at the shooting range was only about 100 meters.

After careful investigation and rejecting someone's lies or other problems, the final analysis results proved that this was an accident. The ordnance experts carefully analyzed the ballistics and trajectories and finally found it possible. They quickly found evidence. On a hill opposite the shooting range, they found bullet marks. The bullets were shown to hit here. Because of the hardness of the rock, they jumped up. Then with the help of wind and altitude, they flew for several kilometers and finally landed on the lady's calf. This was also a bullet of 56 and a half caliber. In the end, it only made a small hole in the calf, which was considered a very mild injury.

Even light weapons can exceed the effective range by 10 times, let alone artillery. Under certain conditions, there is no problem with the effective range of more than two or three times. Important places like hangars and oil depots are threatening in their attack range. Especially for oil depots, any shell drops, even if it is not a high-explosive bomb, it may ignite the oil depot and cause a fire, so necessary precautions are necessary.

After all, this is not a defense zone for China. To a certain extent, China can avoid being captured. It is almost impossible to clear out all the threat range unless China mobilizes 200,000 or even 300,000 troops to make carpet-style defenses dozens of kilometers around the entire airport.

This is unnecessary. China's secret protection of strategic airports has attracted the attention of the Japanese. If hundreds of thousands of troops come in, it would not be like the bright lights of this airport. Even if Japan obeys it on the surface, it will definitely try its best to spy it in the secret. This will easily mess up, but it will be better to strengthen the construction.

According to standardized projects, whether it is a hangar or an oil depot, it can withstand direct attacks of at least 1,000 kilograms of aircraft bombardment. Such protection, not to mention that artillery bombards 20 kilometers or even 30 kilometers away, even if the artillery is placed within 5 kilometers or even within 3 kilometers, the army artillery cannot penetrate this defense at all.

The 7-meter-thick reinforced concrete is all high-grade cement and steel bars, which is equivalent to a standardized steel plate at least a few thousand millimeters. With such a thickness, the main guns of the battleship may not be able to break through continuously, let alone the army artillery. It can be said without hesitation that the ground-boring bullets in later generations can be directly shot from several floors to the ground, and it is not easy to use with such thick and all-round protection.

Fortunately, the construction difficulty of standardized auxiliary projects is not high. Unlike composite laying like runways, those who only need to reach the standard and even use some excellent materials. The construction time is not long. From laying to full operation, it can only take one month to one and a half months. This is just a little tilt for China with sufficient manpower and material resources.

Sakura Airport is a temporary airport, and all auxiliary projects are completed with high standards just like the local government. Even due to the airport construction, the Sakura Plan was postponed by about a week compared to the scheduled one. Of course, this is not all because of the Sakura Airport, and the increase in the number of tanks. It turned out that Japan was only planning to build more than 1,000 tanks, but so many were seized at that time. Who knew that it gradually increased to three divisions and one brigade and 5,000 tanks. Therefore, the entire plan was postponed for one or two months, and it didn't matter if it was delayed for a few days.

It is precisely because this base is a high-standard base that when China gave up this base and handed over the base to the Japanese, the Japanese also used this base. Some of the aircraft knowledge learned from China and the foundation of Japan have become the foundation of Japan's aviation industry. It is not only the largest test site and main airport, but also Japan's other airports in the future, basically compared with this airport.

In the future, during the 20-year war between Japan and the United States, this base has always been the primary target for Americans to learn about the speed. However, because of its protection ability and location choice, under the rapid development of both Japan and the United States, there is no record of being attacked at all. However, the final attack was successful, and at most, a few bombs fell on the runway, causing some damage to the runway.

War is always the fastest time for technological development. Both countries with strong territory and maintain high-strength wars. Because China illuminates the aircraft's skill tree in advance, and China has more or less exported some technologies. Although these technologies have no direct effect on aircraft, they can improve the scientific and technological level from the side. In fact, China's changes not only allow China's technology to develop rapidly in all aspects, but also promote the development of the entire world from the side.

Even if China hides the highest-end technology and technical equipment, strategic aircraft, tanks, and even aircraft carriers, the basic things cannot be hidden, such as cars and various advanced equipment. As long as China exports machinery and equipment, it will inevitably leak some things, because to ensure advancedness, it must be a little more advanced than the machinery and equipment of other countries, otherwise it will not be sold.

There is still no clue like an engine. Many things are not expensive in order to pursue cost, so it is impossible to have a high technical content. If the other party is willing to learn, they will definitely learn it. Here are a little bit, and there are a little bit, in fact, the technological level of the whole world is higher than in history.

All China knows that this is helpless. The pace of backward advances catching up with the advanced should always be faster. When Yang Yuanzhao appeared, not only did China achieve development beyond the times, but also because of China's development, it promoted the development of the world from the side. Some basic science and technology have certain developments, which exceeded the technological level of the same period in history.
