Time travel! Regrets will never happen again!

The Japanese pilots knew that the target area they were bombing had a lot of anti-aircraft firepower. The last time two reconnaissance planes went to conduct reconnaissance, one of the planes was shot down by the Chinese's 20mm anti-aircraft gun.

During the previous bombings, the Chinese air defense forces also had a lot of 20mm anti-aircraft artillery.

In response to this situation, the entire bombing group decided to maintain a cruising altitude of 4000 meters this time.

Wait until the fleet flies over several places and launches an air strike over the target marked by the last reconnaissance aircraft, and then lowers the flight altitude.

In fact, the previous air raids basically took place during the march, and most of the weapons exchanged at that time were 20mm anti-aircraft guns that were easy to transport and transfer.

The large-scale deployment of the Bofors 40mm came after reaching Guancen Mountain.

So much so that the Japanese army thought that the anti-aircraft fire here consisted of dozens of 20mm anti-aircraft guns and a large number of anti-aircraft machine guns.

Of course, we also know that there may be some large-caliber anti-aircraft guns, but the results of the last reconnaissance showed that there were only a few large-caliber anti-aircraft guns.

As long as sufficient altitude is ensured this time, the safety of the fleet should be guaranteed to a certain extent.

"Watch the sky carefully, the radar shows that the enemy aircraft will soon fly over the area under our command!"

A major battalion commander was using a professional air defense optical telescope to observe the eastern airspace while reminding the soldiers at the anti-aircraft artillery position behind him.

该片高炮阵地，是由8门克虏伯88毫米高射炮、12门博福斯40毫米高炮、12门20毫米高射机关炮组成。

There are a total of seven such air defense battalions in the entire Guancenshan base, but their equipment and scale are slightly different.

"Twenty degrees left, southeast airspace ahead, enemy aircraft spotted, altitude 4200! Distance 8000, all gun crews ready!"

With a loud "boom", when the Japanese army flew over the air defense position that was tightly covered by a camouflage net, an 88mm anti-aircraft gun took the lead in conducting correction shots.

Because all anti-aircraft guns of this period relied on mechanical predictive sights, the 78th Army now prioritized the addition of radar technology.

The greatest power of the anti-aircraft artillery here comes from the improvement of the radar setting of the anti-aircraft shells. Wang Chun exchanged a large number of shells equipped with low-altitude explosive fuses. This explosive fuse can be set in the shells and be detonated when approaching the target. This radar technology is revolutionary.

They would also play a vital role in air defense operations in the middle and late stages of World War II.

The gunners on the position stepped on the firing pedal according to the set lead time, and instantly dozens of 88 and 40 mm guns began to spew black and red fireworks towards the Japanese aircraft group.

The Japanese bomber formation adopted a high-altitude dense bombing formation. They had no idea that they would be attacked by large-caliber anti-aircraft artillery just after entering the core area of ​​the Chinese.

"Oh! Bastard! The Chinese have large-caliber anti-aircraft artillery, the Krupp 88mm anti-aircraft gun! Those damn reconnaissance planes, their intelligence has a huge error!"

Captain Yamamoto, as the commander of this bombing mission, personally piloted a Type 1 bomber, which was the latest bomber in service with the Empire's naval aviation force.

The reason for bombing land targets this time was to allow the pilots who were about to be transferred to the Pacific battlefield to adapt in advance.

Let them fly these bombers to bomb some targets with certain air defense capabilities first, so that they will be mentally prepared when they face the US military with stronger air defense firepower later.

I originally thought that I had been very cautious, but in the end I underestimated the strength of this rebel army. They actually had so many large-caliber anti-aircraft guns.

"All crews disperse immediately! Keep increasing altitude!" The Japanese fighter planes at that time were not equipped with onboard radios, so Yamamoto kept commanding the bomber groups through hand gestures.

The entire bomber group fled in all directions like frightened birds. At the beginning, due to the altitude, the artillery fire only exploded below the group.

This gave the Japanese aircraft time to react, but the anti-aircraft gun crew continued to adjust the shooting angle and altitude.

The fragments produced by the explosion of large-caliber artillery shells are far beyond the reach of small-caliber anti-aircraft guns.

The emergence of a large number of new artillery shells caused many of them to explode very close to the fighter planes.

Although the previous rounds of shelling did not hit any target, anyone with a little common sense in air defense operations knows that this is especially true when it relies solely on anti-aircraft artillery fire.

The combat concept of anti-aircraft guns can be summarized in one sentence: anti-aircraft guns can fire blanks, but are not allowed to stop firing.

Intensive and continuous air-to-air launches, although the hit rate is low, there is always a chance of hitting the target.

This is how the 78th Army's air defense forces operate now. They don't care how many shells they fire, they just hope to shoot down as many Japanese bombers as possible.

Shells exploded continuously around the Japanese bomber. The crew of a Type 1 bomber that was rising rapidly felt that their plane suddenly shook violently.

"We've been hit!" The bombardier's shout came from the rear cabin, and at the same time the plane shook even more violently.

A large amount of air poured into the entire fuselage through the large hole in the belly of the aircraft. The strong airflow made the aircraft extremely difficult to control.

Lieutenant Tsuchiyama Tsukaichi, who was flying the fighter plane, held the control stick tightly, but the plane still fell uncontrollably.

"Baga! Damn Chinese!" Tushan cursed the Chinese air defense soldiers below while trying desperately to find ways to stabilize the fighter plane.

"Boom" there was another violent explosion, the entire nose of the plane was like a sieve, Tushan's body was still fixed in the cockpit by a seat belt, but his body was already riddled with holes, and large amounts of blood kept gushing out.

At the same time, a fire broke out in the cabin, and the fire and thick smoke soon enveloped the front half of the plane.

This time the fighter plane was completely out of control and fell to the ground like a lit torch.

The entire sky seemed to be torn into countless pieces. The artillery fire intertwined into a cruel picture. The Japanese bombers were like an ark in the raging sea, struggling to escape.

On the ground, the anti-aircraft artillery positions were extremely busy. The gunners aimed at the aircraft in the air and kept stepping on the launching pads.

The ammunition handlers on the side kept stuffing shells into the barrel. All of them had naked upper bodies, showing their dark skin and graceful muscle lines as they carried the shells.

That strong body was covered with beads of sweat, but everyone was still repeating the mechanical movements tirelessly.

They had only one belief in their hearts, which was that the base and the newly established infrastructure must not be bombed.

That was a new home that tens of thousands of people had worked hard for several months to build. When the Japanese came to bomb it, it was a fight to the death.

As the soldiers on the anti-aircraft positions below devoted themselves to the attack, their condition naturally became better and better, and the Japanese bombers were constantly hit.

The only drawback is that the anti-aircraft positions here have fewer artillery pieces. After the Japanese lost four bombers, the others were out of the range of the anti-aircraft guns.

All the Japanese pilots had a shadow in their hearts.

The wing of Yamamoto's plane was partially damaged by the explosion of a 40mm shell, but it did not seem to be a temporary obstacle to flight.

They were now less than 10 minutes' flying distance from the air raid target, and Yamamoto secretly swore in his heart that he would blow up the new base of these hateful traitors even at the risk of his life.
