When the shrill air defense alarm sounded, passers-by and vehicles who were originally walking on the street stopped, and then stared blankly at the source of the alarm sound in the sky, not knowing what happened.

We can't blame them. In fact, after the war broke out, all over the country had carried out asylum training, etc., but China has not had a large-scale war for more than 20 years, especially in cities like Beijing. It has been peaceful for a long time, so the reactions in some aspects have naturally become much slower.

On the other hand, as the air defense headquarters that has been in peace for a long time, it is also in a state of chaos.

"Damn, how did these things come out!!!"

Looking at the highlights displayed on the radar display and the information sent back from observation stations in various places, Rey Ming's forehead was sweating anxiously.

As the commander of the Air Defense Command, Rey Ming is like this, let alone the others in the department. However, this is no wonder. Although it is the Air Defense Command, there has never been a war since the establishment of the National Social Security Government. The Air Defense Command, which is mainly responsible for Beijing's airspace security, has been idle for more than 20 years. It is not as capable as the border branch. Now that I encounter such a situation, I am naturally confused all of them...

"………Minister, the enemy plane is less than six minutes away from Beijing!!!"

Just as Reyming was anxious and sweating, an officer next to him hung up the phone and shouted loudly at him.

Hearing his subordinates say this, Reyming walked around twice.

"How is the air defense force going?"

"It's already in combat readiness!!!"

"What about the Air Force? Can the Air Force fight?"

If the air force fighter jets in bases near Beijing can take off and meet the enemy, it will naturally prevent Beijing from being attacked, and this will minimize Reyming's responsibility. But if the Japanese planes are really allowed to fly over Beijing and throw a lot of bombs down, then as the commander of the Air Defense Command, Reyming, is responsible.

Therefore, now Reyming has placed almost all his hopes on the Air Force, otherwise the responsibility will be his.

However, the words of his subordinates disappointed Reyming.

"The Air Force has already done this, but it's probably too late!"

Unlike the air defense headquarters that has been pacified for a long time, the training of the troops stationed near Beijing is maintained at a high intensity, and they will even pull these troops to the border to accumulate practical experience. Therefore, the troops stationed in Beijing have always been known for their elite forces, especially the air force.

Since the air force is not as sensitive as the army in this era, in some countries with relatively tense relations, it is common for air force fighter jets to conflict between the two countries. Especially on the border between China and Russia, this kind of thing happens frequently. Therefore, the air force pilots near Beijing have quite rich practical experience...

only…

After all, practical experience and other things cannot play a role in reversing time and space. What's more, even if the pilot has practical experience, it does not mean that the ground crew has it.

Moreover, for the sake of daily maintenance, the Air Force fighter jets are usually stored in the hangar. As for fuel and ammunition, they must be installed during combat to avoid any accidents.

In this way, it will naturally become a fantasy to complete all preparations and take off to meet the enemy in 6 minutes...

———————————————————

Just when Reyming was anxious and sweating, Yan Guang was already being carried by the bodyguard and ran into the nearest underground shelter.

Let’s not mention whether Yan Guang is reliable or not. As China’s supreme leader, his defense measures are naturally the most stringent.

Therefore, the security measures of the entire Presidential Palace are also one of the most stringent places in China, second only to some more confidential places.

For example, on the grass around the Presidential Palace, although it seems to be just a common grass, there are dozens of 30mm six-barrel Gatling machine guns under these grasses. In an emergency, these cannons can be lifted out of the ground to defend against the enemy.

Of course, the existence of these cannons is an extremely secret matter, so there are actually not many people who know about it. In order to avoid being turned around by the enemy and bombarded the Presidential Palace, the firing angles of these cannons are not only fixed, but also can only be used to the outside but not to the inside.

But even so, these cannons still have extremely huge lethality.

On the other hand, there are several huge underground shelters underground in the Presidential Palace, which are exclusively for everyone in the Presidential Palace to take refuge, and these shelters are also connected.

"But, is it really okay here?"

After entering the underground shelter, Yan Guang's secret said that he was a little scared.

Well, after all, the most important thing about secrets is appearance and ability to serve people. Naturally, there will be no courageous people, or courageous people will not come to Yan Guang at all. After all, a courageous woman can easily remind people of Wu Zetian or Cixi...

On the other hand, Yan Guang patted her on the shoulder.

"Safe, there will be no problem..."

When he said this, Yan Guang's face was full of confidence.

Although Yan Guang is no longer able to compare with him when he just traveled to this country, even so, the confidence on Yan Guang's face still soothes the hearts of dozens of secrets nearby.

Of course, there is a reason for Yan Guang to be so confident. You should know that Yan Guang is from later generations, but he is very clear about the power of this nuclear weapon. So when he started researching and manufacturing in Lop Nur, Yan Guang improved the underground shelter in the Presidential Palace based on the opinions of experts.

The shelter is 100 meters deep, consisting of reinforced concrete, and there is a protective layer made of more than ten layers of armor used by battleships on the top of the shelter. Such protection can withstand the power of millions of equivalents of nuclear bombs even in later generations. A hundred tons of equivalents is just a piece of cake.

This is why Yan Guang was so confident. After all, this underground shelter was specially built for a few years later. Today's conventional ammunition is simply impossible to pose a threat to it.

What's more, Japan does not have any large bombers at all, and it only uses some relatively light bombers.

For example, the Type 98 dive bomber used by the Japanese Army Aviation Corps. The air weight is only 1,066 kilograms, and the heaviest is only 3,760 kilograms. Currently, the air weight used by the National Defense Air Force has reached 3,232 kilograms alone, and the maximum take-off weight reaches 5,262 kilograms.

In addition, the Japanese Type 99 twin light bomber was an influence of the Soviet-made SB2 light bomber that appeared on the Chinese battlefield in 1937, and required Kawasaki Aviation to develop a new light bomber. This aircraft is a metal mid-wing aircraft with a three-point landing gear at the rear. The front of the fuselage is a thicker bomb bay. The rear is a smaller tail. The tail vibrates during the test flight of the prototype in 1939, so the tail structure strength must be strengthened and the area of ​​the vertical tail wing must be increased.

However, even so, the empty weight of the Type 99 dual light bomber is only 4550 kilograms and the total weight is only 6500 kilograms.

It is not much better than the zd20, which exists as a fighter.

The remaining Type 1 and 3 land attack aircraft are a little better, with at least the weight of 6,741 kilograms and the maximum load of 12,895 kilograms. However, in the National Defense Air Force, it can only be regarded as a medium bomber. And it is barely...

In addition, even the Type 97 heavy critical strike aircraft equipped by the Japanese army, which is the so-called heavy bomber of the Japanese, has only an empty weight of 6,070 kilograms, and the heaviest is 10,610 kilograms.

In history, the Type 97 equipment was soon used in the Sino-Japanese War. It bombarded Chinese cities, but it was also hit by the Chinese Air Force head-on. The Type 97 initially had only 4 7.7mm caliber ** machine guns, which seemed to be unable to resist when facing the attack of Chinese fighter jets, especially the US-made Browning M2 heavy machine gun. So an equivalent ho103 heavy machine gun was added to the back of its aircraft, and the bullet bay and flaps were also amplified. This is called ki21ib. The fuel tank was also increased based on practical experience and the machine gun was also increased to 6. This is called ki21ic. After 1939, the ki21ii was also produced with a ki21ii with an increase in vertical tail wing.

The Pacific War Type 97, which began in December 1941, also emerged in an empty group, but after 1943, the 97 type still seemed unbearable to deal with all kinds of Allied fighters (even the old British hurricane fighter). Although the production of the 97 type continued until 1944, it was called an out-of-time model, so production was stopped in September of that year.

The heavy bombers equipped by the Army are still like this. Although Japanese fighters are still quite outstanding, such as Type 4, Type 5, and Zero Warfare, the bomber can only be said to be really not good...

On the other hand, as a bomber with relatively poor performance, the first-type land attack aircraft can only carry 60 kilogram bombs with 12,250 kilogram bombs with 4,500 or 800 kilogram bombs with 1. The Type 97 heavy critical strike aircraft is a 1,000 kilogram bomb, the Type 99 dual light bomber is 800 kilograms, and the Type 98 dive bomber is only 450 kilograms...

This kind of bomb, not to mention Yan Guang, located under an underground bunker that is 100 meters deep, even the ten-meter-thick soil on the surface of the bunker may not be able to blow up...

"So, don't worry, we are absolutely safe here..."

As he persuaded the secret in his arms, Yan Guang looked up at an official from the Presidential Palace beside him.

"How is the evacuation of the people in the city?"

In the case of absolute safety of his own, Yan Guang was very worried about the situation of the people.

When he heard Yan Guang's question, the official said without looking straight.

"Please rest assured that the evacuation work has begun in the city. In addition, the civil defense project has been greatly promoted over the years, so I believe there will be no problem."

Civil defense projects, also known as fortifications, refer to underground protective buildings built separately to ensure the concealment of personnel and materials in wartime, civil air defense command, and medical rescue, as well as basements that can be used for air defense during wartime built in combination with ground buildings. Civil defense projects are important facilities to prevent sudden enemy attacks, effectively conceal personnel and materials, and preserve the potential of war.

The newly built civil defense projects have undergone feasibility demonstration before construction, taking into account the needs of air defense in wartime, and taking into account the needs of daily economic construction, urban construction and people's lives, and have the dual functions of peace and war.

Generally speaking, subways, underground passages and underground parking lots are all types of civil defense projects.

Although Beijing belongs to a relatively ancient city, after the Kuomintang-Social Government began to take power, it retained a large number of historically valuable buildings, and also flattened some old-fashioned buildings with no value and built new streets, buildings, subways, etc.

Of course, sewers and other things are also in renovation projects.

Moreover, the newly built sewer has basically reached the point where cars can be driven.

It can be said that nothing else is mentioned, at least the sewer can be regarded as advanced even in later generations.

Of course, the cost of building such a large sewer must be quite huge, and the funds are invested in such a place that is basically invisible. The controversy is naturally quite huge, but these were all passed under Yan Guang's "intentional action".

After all, Yan Guang knew very well that it would not take long for the world to break out. Although according to Yan Guang's estimate, it would be difficult for this war to affect Beijing, but be careful, and even if it survives World War II, isn't there a Cold War later?

On the other hand, subway and other projects have also been connected to the entire Beijing in the past twenty years.

therefore…

In terms of civil defense engineering, there is indeed no need to worry about it...

"so…"

Thinking of the funds spent in the past twenty years, Yan Guang nodded.

"Since this is the case, I'm relieved, but... how did the Japanese come to Beijing before they were discovered?"

When he said this, Yan Guang's face looked a little ugly.

He was actually knocked to the house by the Japanese. This was a rare shame for Yan Guang.

Of course, Yan Guang was also very strange. How did the Japanese call him?

You know, if it is said that cities in coastal areas such as Northeast or Shandong were air strikes, he was not very surprised, after all, there is not very far from Japan, and it is not easy to prepare for defense.

But Beijing is different. If you want to enter Beijing, you need to pass through the defense circle of Dalian or Weihai no matter how you go. There are quite a number of high-performance radars in these two places...

In addition, in the Bohai Bay, there are also Air Force patrol aircraft that specialize in patroling.

Therefore, at least in Yan Guang's view, it is impossible to appear in the airspace around Beijing without warning.

However, the fact is that they did come, and they came very suddenly...

———————————————————

"this…"

When the officials heard Yan Guang's question, the officials' faces were covered with sweat, which was almost the same as those of Rey Ming of the Air Defense Command.

In fact, he is also very strange now, what exactly did the Japanese do?

You should know that as the capital of China, Beijing is quite strict in guarding this city. For example, several cities that guard Beijing such as Dalian and Weihai have deployed a considerable number of defense facilities, plus various military aircraft that patrol uninterruptedly every day.

It was impossible for them to appear near Tianjin so suddenly, but now the Japanese did it, which was like slapping them in the face.
To be continued...
