When the terrible air raid sirens sounded, all the passers-by and vehicles that were originally walking on the street stopped, and then stared blankly at the source of the sirens in the sky, not knowing what was going on.

They can't be blamed, in fact, after the outbreak of the war, evacuation training and so on were carried out all over the country, but after all, China has not had a large-scale war for more than 20 years, especially in cities like Beijing.

On the other hand, the Air Defense Command, which has also been in peace for a long time, is also in a state of chaos.

"Damn, how the hell did these things come about!!"

Looking at the bright spots displayed on the radar monitor, as well as the information transmitted from various observation stations, Lei Yiming's head was sweating urgently.

As the commander of the Air Defense Command, Lei Yiming is still like this, not to mention other people in the department. But it's no wonder, although it is the Air Defense Command, but since the establishment of the Nationalist Government, there has never been a war near Beijing, and the Air Defense Command, which is mainly responsible for the security of Beijing's airspace, has been idle for more than 20 years, and it is not as good as the border sub-bureau has the ability to respond.

“……… Minister, the enemy plane is already less than six minutes away from Beijing!! ”

Just when Lei Yiming's head was sweating in a hurry, an officer on the side hung up the phone and shouted at him.

Hearing his subordinates say this, Lei Yiming turned around twice in place.

"How's going on with the air defense?"

"It's already in combat readiness!!"

"What about the Air Force? Will the Air Force be able to meet the challenge? ”

If the air force fighters at the base near Beijing can take off to meet the enemy, Beijing will naturally be able to avoid air raids, and in this way, Lei Yiming's responsibility will be minimized. But if you really let the Japanese plane fly over Beijing. By the way, if a large number of bombs are thrown down, then as the commander of the Air Defense Command, Reimin has an unshirkable responsibility.

Therefore, now Lei Yiming has pinned almost all his hopes on the Air Force, otherwise the responsibility will be his.

However, the words of the subordinates. But Lei Yiming was disappointed.

"The Air Force is already doing this, but I'm afraid it's too late!"

Unlike the Air Defense Command, which has been in peace for a long time, the training of the garrisons near Beijing is maintained at a high intensity, and even in peacetime, these troops will be pulled to the border to accumulate actual combat experience. Therefore, the troops stationed in Beijing have always been known for being elite, especially in the air force.

Because the air force is not as sensitive as the army in this era, in some countries with more tense relations, it is not uncommon for the air force fighters of the two countries to clash, especially on the border between China and Russia.

Merely...

Actual combat experience or something, after all, can't play a role in reversing time and space. What's more, even if the pilot has actual combat experience, it does not mean that the ground crew has.

Moreover, in order to facilitate daily maintenance, the fighters of the Air Force are usually stored in the hangar, and as for fuel and ammunition, they will only be installed during the operation to avoid any accidents.

And so it goes. If you want to complete all the preparations and take off to meet the enemy in 6 minutes, it will naturally become a fantasy...

————————————————————

Just when Lei Yiming was sweating anxiously there, Yan Guang had already been carried by the bodyguards and ran into the nearest underground shelter.

Putting aside the fact that Yan Guang is reliable or not, as the supreme leader of China, his protection measures are naturally the strictest. …,

Therefore, the security measures of the entire presidential palace are also the whole of China. No, one of the most entrenched places in the world, second only to some of the more secretive places.

It's like in the grass around the Presidential Palace. Although it seems to be just ordinary grass, underneath these grasses are dozens of 30mm six-barreled Gatling cannons, which can be manually lifted out of the ground to defend against enemies in an emergency.

Of course, the existence of these cannons is a matter of great secrecy, so not many people actually know about it. And in order to avoid being turned around by the enemy to bombard the presidential palace, the firing angles of these cannons were not only fixed. And it can only be external and not internal.

But even so, these cannons have extremely lethal power.

On the other hand, there are several huge underground shelters under the Presidential Palace, which are reserved for everyone in the Presidential Palace, and these shelters are also interconnected.

"Is it really okay here, though?"

After entering the underground shelter, one of Yan Guang's secretaries said with some fear.

cough, after all, the most important thing to be a secretary is appearance and the ability to serve people, naturally it will not be a person with much courage, or a person with courage will not come to Yan Guang's side at all, after all, a woman with courage is easily reminiscent of Wu Zetian or Cixi...

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

"Don't worry, there won't be any problems..."

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

Although because of the years, Yan Guang can no longer be compared with him when he first crossed over to this country, but even so, the confidence on Yan Guang's face still calmed the hearts of dozens of secretaries nearby.

Of course, there is a reason why Yan Guang would be so confident, you must know that Yan Guang is a person from later generations, but he knows very well how powerful the nuclear weapon of the [Atomic Bomb] is. So when the [Atomic Bomb] began to be researched and manufactured in Lop Nur, Yan Guang improved the shelter under the presidential palace according to the opinions of experts.

The shelter is 100 meters deep, made of reinforced concrete, and on the top of the shelter there is a protective layer composed of more than 10 layers of armor used by battleships, which can withstand the power of millions of equivalent nuclear bombs in later generations, and the 100-ton equivalent is just a piece of cake.

This is also why Yan Guang is so confident, after all, this underground shelter is specially built for [nuclear weapons] that will only appear in a few years. Today's conventional ammunition simply does not pose a threat to it.

What's more, Japan did not have any large bombers at all, and only some relatively light bombers were used.

For example, the Type 98 dive bomber used by the Japanese Army Aviation has an empty weight of only 1,066 kilograms, and the heaviest is only 3,760 kilograms, while the ZD-20 used by the National Defense Air Force alone has an empty weight of 3,232 kilograms. The maximum take-off weight reached 5262 kg.

In addition, the Japanese Army's Type 99 twin-engine light bomber was a new type of light bomber developed by Kawasaki Aviation in 1937 when the Imperial Japanese Army was affected by the Soviet-made SB-2 light bomber that appeared on the Chinese battlefield. This aircraft is a metal medium monoplane with a rear three-point landing gear and a thicker bomb bay in the front of the fuselage. The rear part is a relatively small tail, and the tail vibrates during the test flight of the prototype in 1939, so the structural strength of the tail should be strengthened and the vertical tail area should be increased.

However, even so, the empty weight of the Type 99 twin-engine light bomber is only 4,550 kilograms, and the full weight is only 6,500 kilograms.

Compared to the ZD-20, which exists as a fighter, it is not much stronger.

The remaining Type 1 and 3 land attack aircraft are a little better-looking, at least with a dead weight of 6,741 kilograms. The maximum load reached 12895 kg, but it can only be regarded as a medium bomber in the Wehrmacht Air Force, and it is barely .......

In addition, even the Type 97 heavy bomber equipped by the Japanese army, which is what the Japanese call a heavy bomber, has only 6,070 kg of empty weight. The heaviest is 10,610 kg.

In history, the Type 97 equipment was soon used in the Sino-Japanese War, bombing Chinese cities indiscriminately, but also by the Chinese Air Force head-on, the initial Type 97 only had 4 7.7 mm caliber machine guns, in the face of the attack of Chinese fighters, especially the attack of the American-made Browning M2 heavy machine gun, it was powerless, so it added a Ho-103 heavy machine gun equivalent to it on the back of the aircraft. In addition, the bomb bay and flaps were enlarged, known as the Ki-21-Ib, and the fuel tank was later enlarged based on actual combat experience. The number of machine guns was also increased to six, which was called the Ki-21-IC, and after 1939, production of the Ki-21-II with an enlarged vertical tail was also started.

The Pacific War that began in December 1941 also came out of nowhere, but after 1943, the Type 97 faced all kinds of Allied fighters (even the old British-made Hurricane fighters), and the production of the Type 97 continued until 1944 because it was called an outdated species. As a result, it was discontinued in September of that year.

The army is equipped with heavy bombers, although the Japanese fighters are still relatively good. It's like a four-type, a five-type and a zero-battle or something, but the bomber side can only say that it really can't be ...

On the other hand, as a bomber with relatively scummy performance, a land attack aircraft can only carry 12 rounds of 60-kilogram bombs, 4 rounds of 250-kilogram bombs, and 1 round of 500 or 800-kilogram bombs. The Type 97 heavy bomber is a 1,000-kilogram bomb, the Type 99 twin-engine light bomber is 800 kg, and the Type 98 dive bomber is only 450 kg...

This kind of aerial bomb, not to mention the Yan Guang located under the 100-meter-deep underground bunker, even the 10-meter-thick mud on the surface of the bunker may not be able to blow through...

"So, rest assured, we're absolutely safe here..."

Persuading the secretary in his arms like this, Yan Guang looked up at an official of the presidential palace on the side.

"How's the evacuation of the people in the city?"

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

Hearing Yan Guang's question, the official did not squint.

"Please rest assured that the evacuation work has begun in the city, and the civil air defense project has been greatly promoted in recent years, so I believe there will be no problems."

Civil air defense engineering, also called civil air defense fortifications, refers to underground protective buildings built separately to ensure the shelter of personnel and materials in wartime, civil air defense command, and medical aid, as well as basements that can be used for air defense in wartime built in combination with ground buildings. Civil air defense engineering is an important facility for guarding against a sudden attack by the enemy, effectively covering personnel and materials, and preserving war potential.

The newly built civil air defense projects have undergone feasibility studies before construction, taking into account the needs of air defense in wartime, as well as the needs of economic construction, urban construction, and people's livelihood in peacetime, and have the dual functions of peacetime and wartime.

Generally speaking. Subways, underpasses and underground parking lots are all a type of civil air defense project.

Although Beijing is a relatively old city, after the Nationalist government began to take power, while retaining a large number of buildings with historical value, it also bulldozed some old buildings with little value and built new streets, buildings, subways, etc.

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

but also newly built sewers. Basically, it has reached the point where you can drive a car.

It can be said that if nothing else, at least the sewer can be called advanced even in later generations.

Of course, the cost of building a sewer of this scale must be quite enormous, and the money is invested in such a largely invisible place. The controversy is naturally quite huge, but these have all passed under Yan Guang's 'obstinacy'.

After all, Yan Guang knows very well that it will not be long before an extremely tragic war breaks out in this world, although according to Yan Guang's estimates, it is difficult for this war to affect Beijing, but it is not a big mistake to be careful, and even if it survives the Second World War. Isn't there another Cold War in the back? …,

On the other hand, subway and other projects have also run through the whole of Beijing in the past 20 years.

Therefore...

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

"So..."

Thinking of the money spent over the past twenty years, Yan Guang nodded.

"I'm relieved in that case, but ......... How did the Japanese get to Beijing before they were discovered? ”

When I say that. Yan Guang's face was somewhat ugly.

was actually put on the door by the Japanese, which is a rare shame for Yan Guang.

Of course, Yan Guang is also very strange about how the Japanese came to fight.

You know, if it is said that cities in coastal areas such as Northeast China or Shandong have been attacked by air raids, he is not very surprised. After all, it's not very far from Japan, and it's not very easy to prepare.

But Beijing is different, want to enter Beijing. No matter how you go, you need to go through the defense ring of Dalian or Weihai, and in these two places there are a considerable number of high-performance radars...

In addition, in the Bohai Bay, there are also patrol planes of the Air Force that carry out special patrols.

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

But the truth is, they did. And it came quite suddenly...

————————————————————

"This..."

Hearing Yan Guang ask, the official's face was also sweaty. It's about the same as Reimin in the Air Defense Command.

In fact, he is also very curious now, how exactly did the Japanese do it.

You must know that Beijing, as the capital of the whole of China, can be said to be quite tightly guarded by the city, for example, in Dalian, Weihai and several other cities that defend Beijing, a considerable number of defense facilities have been deployed, plus various military aircraft that patrol every day.

It would have been impossible for them to appear so suddenly near Tianjin, but now that the Japanese have done it, it is like a slap in the face.

"Forget it..."

Seeing that the official was in front of him but couldn't say anything, Yan Guang waved his hand.

"Go, call the Military Intelligence Bureau, ask them why they didn't notice this matter in advance, and by the way, let them check how the Japanese bypassed."

"Yes!"

Of course, Yan Guang and others did not know that in order to implement this retaliation plan, the Japanese could be said to have spent blood. Not only was the whole plan kept in a state of extreme secrecy, but it also deliberately launched a small number of spies who had survived and remained in the latent stage under the purge of the Military Defense Bureau, so that the Japanese movements could not be detected by the Military Intelligence Bureau.

At the same time, it was also through these spies that they learned about the patrol time of the patrol planes at the Dalian and Weihai bases, and created some time lag through various means, so that the bomber groups carrying out the retaliatory mission could fly between the patrol planes of the two bases along this time difference.

As for how they bypassed the radar stations in the cities of Dalian and Weihai ...

In this era, radar is definitely a well-deserved advanced technology, but in advanced technology, there will be some problems when it is just launched. And these problems are likely to be quite fatal.

In later generations, the American F-22 "Raptor" fighter was the most advanced active fighter in the world at that time, and its performance formed an overwhelming advantage over the active fighters of various countries. However, since 2008, pilots have reported failures in the F-22's oxygen supply system, in 2011. The U.S. Air Force grounded F-22 captains for five months to solve this problem.

It can be seen that when a new thing is just born, there will always be quite a lot of problems. …,

Of course, there is actually another theory about the problem of the F-22, that is, back in 2000. The military has been informed that the F-22's on-board oxygen supply system has a fatal risk and has given a solution in classified documents. Incredibly, the military turned a deaf ear to this out of "cost considerations", which led to a tragedy.

In addition, the F-22 can be said to be the only fourth-generation aircraft in active service in later generations, and even the F-35 is not counted, because according to the 4S standard proposed by the Americans themselves, supersonic cruise alone is the item. It's not something that the F-35 can achieve, or the 'fat electricity' simply doesn't have the ability to cruise at supersonic speeds.

In fact, in the 4S standard, the 'fat electricity' does not have supersonic cruise, and the super-maneuverability is also unsatisfactory, and the stealth performance is inferior to the F-22 because of the hypertrophied and uneven body. Only super-perception is the strength of the F-35.

Also the latest news is that Canada has decided not to buy F-35s anymore ...

Because this is simply a 10,000-year-old pit...

As for how exactly the Japanese bypassed the radar stations located in Dalian and Weihai, in fact, the reason is simple, flying at low altitudes ...

It can only be said that the Air Defense Command is too dependent on radar, and this weakness of the radar has not been discovered at all, as long as it flies at ultra-low altitudes. Radar stations or something will not be able to detect low-flying targets.

This weakness was learned by the Japanese from the Germans.

————————————————————

"Is this Beijing..."

Piloting the Type 97 heavy bomb plane, Mishima Kazuo said coldly.

As a Tokyoite. Both of his parents died in the recent bombing, and it was for this reason that Mishima was the first to stand up when the military department decided to carry out this mission with a high mortality rate.

For him, it was a battle for revenge, and he didn't even think about going back alive.

"So. Where are you going to bomb first..."

The Type 97 heavy bomber is not a heavy bomber like the H-3 or H-40, and cannot carry several tons of ammunition. Therefore, with limited ammunition, Mishima could only select some targets for bombing first.

At this time, Mishima saw a tall building, and he even saw some people running into it.

"Well, let's blow it up!!"

Looking at the people who were running from the gate to the tall building, Mishima smiled cruelly.

Just as Mishima lowered the nose of the plane and flew towards the tall building, the police and some Wehrmacht soldiers were also directing the crowd on the ground.

"Quick, quick, fast!!"

Standing at the gate of a shopping mall, a policeman shouted at the crowd screaming and running towards the mall.

"There is an underground passage in the mall, so it's no problem to hide there!!"

In fact, many newly built commercial buildings in Beijing have one or two floors of underground space, which are used as underground shopping malls.

In fact, even in later generations, there are many shopping malls with so-called underground shopping malls.

Many of these malls feel very narrow when you enter them, like passages one by one, and they are used to avoid air raids at critical moments.

However, Mishima is not aware of this, and since Beijing is a populous city, there are quite a lot of people piled up at the gate of the mall now, so...

"Die!!"

Looking at the people on the ground, the bombardier behind Mishima pressed the button.

Four 250-kilogram bombs fell from the bomb compartment and landed near the gate of the shopping mall, although the power of the 250-kilogram bomb is not very large, at least it will definitely not bring any damage to Yan Guang's nuclear bunker-level underground shelter, but for vulnerable human beings, the power of the 250-kilogram bomb is already large enough......

With just a 'boom', the people who were originally piled up at the gate had already collapsed, and in the case of a bomb directly hitting the mall, the mall itself directly collapsed a large piece...

At this time, maybe the people in the mall have already gone underground, or maybe they haven't, who knows...

"It's time to go back..."

After circling in the airweight, signaling the machine gunner to shoot at the ground and start over at the civilians who were not yet dead, Mishima piloted the plane on its way back to North Korea.

The Type 97 Heavy Explosive Fighter has four 7.7 mm machine guns and a 12.7 mm Ho-103 heavy machine gun arranged in the back, although the 12.7 mm one cannot be easily used, but the 7.7 mm one is no problem.

As he began his way home in the plane, Mishima passed by a school.

When he saw the school, Mishima remembered his time at school, and also considered whether to fly a plane to the school for a 'kamikaze', of course, at this time Japan did not have a kamikaze team, but Mishima did not mind coming by himself.

It's just that considering that Japan's resources are not very many, especially the construction of a Type 97 heavy explosive aircraft requires a lot of resources for Japan, so in the end Mishima had no choice but to give up. After all, on the way here, the officers above did not give Mishima more orders.

However, just as Mishima, under the guidance of the co-pilot, began to return to North Korea, the anti-aircraft fire on the ground suddenly became fierce.

It didn't take long for the wing of the heavy bomber piloted by Mishima to be punched out of a hole.

"Damn !!"

If Mishima still had the heart to die just now, now he only has the heart of not wanting the Chinese to succeed.

After pulling the nose of the plane, Mishima began to fly the plane high into the air.

However, not long after he flew, Mishima noticed that four fighter jets were flying towards him.

"It's !!"

Looking at the four planes flying over, the co-pilot said with some surprise.

In fact, there is no need for him to say more, Mishima already understands that this is a fighter of the Wehrmacht Air Force.

As a matter of fact, the army and navy had already given them a lot of information about this kind of fighter when they set off from the three islands—————— after all, on the Taiwan side, the army and navy had lost quite a lot of fighters.

Therefore, Mishima and the others also understood that with the kind of bomber they were piloting, it was really impossible to escape the four enemy planes in front of them, which were not even opponents in the Zero Battle, and only the latest new fighters could slightly match them.

But although it is impossible, Mishima is not willing to give up, so...

"Come on!!"

Looking at the four ZD-20s, Mishima did not dodge, and directly drove the plane towards them head-on, and at this time the four ZD-20s on the opposite side also opened fire ...

More than a minute later, the air defense soldiers on the ground found that the Japanese bomber just now was dragging the smoke and falling towards the ground not far away...

————————————————————

Although the Japanese acted very suddenly, Beijing is the capital of China after all, and it has a considerable degree of defense force here, so in the end, all the enemy planes that attacked were shot down, and none of them were able to return to Korea—————— which is also a very normal thing, after all, not to mention Beijing's air defense fire and the surrounding air force, there are a considerable number of fighters in Tianjin alone who are ready to intercept them, and it is a strange thing that they will be allowed to run away.

However, even if all the hundreds of bombers were destroyed, the Chinese side still paid more than 1,000 casualties, although these casualties were nothing compared to Japan, but the casualties of more than 1,000 people still slapped the Kuomintang government hard.

At the same time, these casualties also made many people understand that in war, people will die...
