Chapter 230: Brush some super fire

In the border area and the Dawn Research Institute, Ren Zhong welcomed familiar guests again.

"Brother Ren, according to your reminder, our intelligence personnel lurking near the Japanese North China Airport have sent back the latest intelligence showing that the Japanese have assembled dozens of advanced Zero fighters at the Yanjing Airport.

After the Japanese suffered from the 107mm fire, the outer security circle of the key airport has been expanded to eight kilometers away. Our method of infiltrating the airport and attacking is no longer feasible. "

Staff Officer Ye said with a distressed look on his face.

Thanks to Ren Zhong's advance knowledge, Staff Officer Ye was already very familiar with the Japanese fighters. Among the advanced fighters of the Japanese at this time, the most likely ones that could appear in North China were the Zero fighter (the weapon system was equipped with two Type 99 20mm cannons, 60 rounds of ammunition, and two other 7.7mm machine guns) and the Nakajima Type 1 "Falcon" fighter and the Nakajima Type 2 "Zhong Kui" fighter. The main weapons of these two types were two 12.7mm machine guns, which were considered advanced models of East Asian fighters in World War II. They were barely capable of fighting the P51D Mustang fighter.

The Japanese's original main force, the Type 97 fighter, had two 2mm machine guns installed on each side of the wing. This outdated configuration was completely unsuitable for fighting against the high-end P7.7D. No matter how many came, they would be useless.

However, Ren Zhong did not dare to neglect the Zero fighter. After all, most of the pilots in his Shenying Squadron were rookies, and they could still maintain the upper hand against the Type 97 fighter.

When fighting against Zero fighters, Ren Zhong did not dare to expect that they could defeat the majority with a minority.

"Go to General Shi to ask for elite pilots and air cover for the North China battlefield. This battle has a bearing on the entire East Asian war situation. We can provide airport services and logistical supplies in Jin. We will need at least two squadrons." Ren Zhong was well prepared for this.

"Air supremacy is very important in this battle. On the ground, our weapons and equipment are no weaker than those of the Japanese field divisions. Coupled with the advantage of terrain, if there is no Japanese air threat, our strength has expanded to the point that no matter how many directions the Japanese attack, we will be able to deal with it," Ren Zhong explained.

"The shortcoming now is that our own air force is too weak. We must request external assistance to make full use of our hard-earned more than 20 advanced fighters of the Divine Eagle Squadron to try to offset the air threat. We must pay great attention to this point, otherwise if a large number of Japanese bombers appear above our troops, this battle will become the same as the first battle."

Although the situation was not as serious as Ren Zhong said, in order to prevent things from getting out of control, Ren Zhong still tried his best to facilitate the Allied air support in North China.

The Allied Air Force now has a considerable force, but it has been used to cover the rear. Although this is also very important, at the current stage, Ren Zhong hopes that they can deploy part of it over North China to offset the Japanese Air Force.

"We will do our best in this matter." Staff Officer Ye knew how powerful the Air Force was. He had a deep understanding of how strong the air force's ability to suppress the ground was.

"The second thing is that I need the comrades lurking at the Japanese's main airports to pass on the information to me in a timely manner when the Japanese fighter planes are parked at the airports with the largest number." Ren Zhong added seriously.

"We will attempt to launch a long-range strike on the Japanese-occupied airfield using our latest Dongfeng Express 1A rockets."

"What? Our long-range rockets have begun to have strike capabilities?" Staff Officer Ye said with some surprise when he heard this.

"It is difficult to evaluate the effect now. The error in hitting long-range targets is as high as 1000 meters. If I have a choice, I don't want to use this weapon now, but under the current circumstances, we have to try its strike capability." Ren Zhong explained.

The Dongfeng 1A already has a long-range strike capability of 900 kilometers, and the circular probability error of the test attack has been reduced to 1000 meters. For a target like an airport, this is still too large.

Theoretically, several major airports of the Japanese in North China, including the Pingjin Airport, are within the attack range of the Dongfeng 1A, but whether the Japanese fighter planes at the airport can be accurately destroyed through long-range strikes is a question.

Even in terms of warheads, military workers have improved the warhead's strike method according to the cluster bomb method and completed the research on cluster submunition warheads. Now they can be equipped with one ton of submunitions to launch attacks, and the killing range of one submunition exceeds 5000 square meters.

Therefore, even if there are errors, this lethal range can make up for it to a certain extent.

However, the killing of innocent people in the surrounding area is inevitable.

Because this is a very pure area-killing weapon.

"This weapon is also very dangerous for intelligence personnel who are observing closely. If possible, after confirming the target, it is relatively safer for on-site intelligence personnel to immediately withdraw 3 kilometers away from the target," Ren Zhong reminded.

"No, we can't be too far away from the target, otherwise we won't be able to carefully evaluate the effectiveness of the attack. We will instruct our intelligence personnel to try their best to hide in the cellars dug near the airport." Staff Officer Ye shook his head and refused.

"We spent a lot of effort, and even sacrificed many comrades, to gain an opportunity to sneak into the cellar 3 kilometers away from the airport, so that we could observe the situation of the Japanese airport and return a lot of intelligence information. He will not leave the ambush site until the attack is completed."

There are many things that need to be done by someone.

The airport was one of the most important places for the Japanese to defend, and the security was very tight. In order to break through the numerous obstacles, they had to dig a cellar near the airport and sneak a person in for long-term observation.

This is a very difficult task.

Ren Zhong didn't know how they did it.

But now at least intelligence has been returned from Yanjing Airport. As for the location information of the airport, Ren Zhong confirmed their precise latitude and longitude information through research and comparison between the two worlds. If several missiles are used to cover and strike it, according to the current cluster bombs, there is a high probability that an airport will be destroyed.

There is only one chance like this, and it needs to be planned well to maximize the effect.

In the great desert, five Dongfeng 5A missiles are ready for battle.

Since Ren Zhong provided the latitude and longitude targets of the Yanjing Airport, Professor Qian and his team carefully calculated how to use three Dongfeng 3A missiles to destroy the entire Yanjing airport.

Theoretical calculations and on-site adjustments have been done several times, and just waiting for Ren Zhong's order, the three Dongfeng 3A missiles will rush towards the target.

Even though Ren Zhong never said that they should always be in a state of combat readiness, Professor Qian and his colleagues still do their best to maintain them every day to ensure that these rockets can be launched at any time!
They all heard the news from the front line. Ever since Ren Zhong decided to launch the attack using Dongfeng Express, Professor Qian and his team had been in a state of excitement.

Since this large firecracker was developed, it has only been tested for accuracy, and has never been tested with a real weapon on its warhead.

Because Ren Zhong felt that it was unnecessary. There was a lot of test data in the main world to show the impact effect of each warhead. A full ton of ammunition was not cheap. It was good enough to take the sand with him. There was no need to waste it.

One ton of TNT can be used to make hundreds of large-caliber artillery shells. A 105mm grenade has a TNT content of just over 2 kilograms. If one ton is used for testing, more than 1 grenades will be lost.

Now the L105 howitzer has achieved large-scale mass production. Its marching weight is 2.2 tons, the weight of the entire gun is 1.6 tons, the barrel is 2310 mm long (22 times the caliber), the caliber is 105 mm, the elevation range is -5°~+65°, the directional range is 45° on each side, the high-explosive grenade weighs 15 kg, the initial velocity is 472 m/s, the maximum range is 11270 m, and the rate of fire is 16 rounds per minute, which almost replicates the performance of the M2A1.

Compared with the main performance of the Japanese Type 105 1500mm howitzer, the total weight of the gun is 2137 kg, weighs 2090 kg in marching state, the barrel is 20 mm long (105 times the caliber), the caliber is 5 mm, the vertical firing range is -43°~+20°, the horizontal firing range is 10900° on each side, the maximum range is 6 meters, and the rate of fire is 8- rounds per minute.

The L105 howitzer has an overwhelming advantage.

In addition, because Ren Zhong improved the quality of the gun steel, the service life was increased from 5000 to 7500 rounds in the original version to more than 10000 rounds.

When the Taiyuan Campaign was launched, all four L4 artillery battalions accumulated in the border area were pulled across the Yellow River and became the trump cards of the 105st and nd Artillery Regiments of Northwest Shanxi.

But now they are hiding and have not taken action yet, surrounding the First Army in Taiyuan, waiting for the Japanese reinforcements to arrive. This time, the Border Region General Staff and the Eighth Route Army Headquarters prepared a large-scale siege and attack drama for the Japanese.

Of course, from now on, the fish that were lured out seem to be a bit too big, and it is a bit difficult to lure them in now.

After three days of conspiracy with Staff Officer Ye, the intelligence officer lurking near the airport finally sent back information.

"The pheasants are coming back to their nests, hurry up."

According to the agreed code names, the Japanese Type 97 fighter was codenamed "Tu Ji", the Shan Ji was the Zero fighter, and the Ye Ji was the Type 1 fighter.

When these radio waves reached the Border Region Staff Headquarters, they were quickly passed on to Ren Zhong and the Dongfeng Express Team.

This time, Ren Zhong did not hesitate and immediately ordered the ignition of three rockets that had already been prepared for launch!
Soon, three superfire missiles shot up into the sky, then adjusted their posture in the air and flew towards a distant target. After entering level flight, their maximum flight speed exceeded 3 meters per second, which is an astonishing speed of Mach 2210.

Even so, the distance from the base to the target is more than 700 kilometers, and theoretically it will take more than 6 minutes to fly from the base to the target.

So, when the rocket takes off, the next few minutes feel particularly long.

Professor Qian looked at the trajectory of the rocket disappearing in the sky and couldn't help feeling a little nervous. In order to carry out this attack well, he and the project team spent several days checking the calculations.

From the precise measurement of local longitude and latitude, to the confirmation and calculation of the longitude and latitude of the Japanese airport, and the calculation of the coverage probability of the rocket hit error, every link was calculated accurately many times.

They even recruited several young mathematicians from the Dawn Research Institute to help with the verification - at the base, there were quite a few mysterious computers that could use formulas and calculation speeds to verify the manual results very quickly.

As the computer room with the most strict management in the Dawn Institute, it was named Jiuzhang Laboratory.

And those computers, in this time and space, have a Chinese name - Shen Suan Zi.
