#230 - Brush a few super fire
At the Border Region's Dawn Institute, Ren Zhong welcomed familiar guests once again.
"Old Ren, as per your reminder, our intelligence personnel lurking near the Little Devils' North China airport have sent back the latest intel, showing that the Little Devils have amassed dozens of advanced Zero fighters at Yanjing Airport.
Having suffered from the 107 rockets, the Little Devils have now expanded the perimeter警戒circle around key airports to eight kilometers. Our method of infiltrating and attacking near the airport is no longer very feasible," Chief of Staff Ye said with a troubled expression.
Thanks to Ren Zhong's prior popularization of knowledge, Chief of Staff Ye now has a very good understanding of the Little Devils' warplanes. Among the advanced warplanes of the Little Devils during this period, those likely to appear in North China are mostly the Zero fighters (weapon system equipped with two 99-type 20mm cannons, with 60 rounds of ammunition, and two additional 7.7mm machine guns), as well as the Nakajima Type 1 "Hayabusa" fighter and the Nakajima Type 2 "Shoki" fighter. The main weapons of these two types are two 12.7mm machine guns. In the East Asian theater of World War II, these were considered advanced models, barely capable of fighting the P51D Mustang fighter.
The Little Devils' original main force, the 97-type fighter, had two 7.7mm machine guns installed on each side of the wing. This outdated configuration was completely unworthy of fighting the P51D in high-end battles; sending as many as they had would only be delivering food.
However, Ren Zhong did not dare to be negligent towards the Zero fighter. After all, his Divine Eagle Brigade pilots were mostly rookies, and they could only maintain the upper hand when fighting the 97-type fighter.
When fighting the Zero fighter, Ren Zhong dared not expect them to fight the many with the few.
"Ask General Shi for some elite pilots and air cover in the North China theater. This battle is related to the entire East Asian war situation. We can provide airport services and logistical support in Jin Province, with at least two squadrons or more," Ren Zhong had already prepared for this.
"Air supremacy is very important in this battle. On the ground, our weapons and equipment are no weaker than the Little Devils' field divisions. Coupled with the advantage of terrain, if there is no aerial threat from the Little Devils, our strength has now expanded to the point where no matter how many routes the Little Devils attack from, we have ways to deal with it," Ren Zhong explained.
"The current shortcoming is that our own air force is too weak. We must request foreign aid to make full use of our hard-won Divine Eagle Brigade of over twenty advanced warplanes, and try to offset the aerial threat as much as possible. This point must be taken very seriously, otherwise, if a large number of Little Devils' bombers appear over our troops, this battle will go down the old road of the First Battle."
Although the situation was not as severe as Ren Zhong described, in order to ensure that the development of the situation did not go down an unmanageable path, Ren Zhong still tried his best to promote Allied air support in North China.
The Allied Air Force already had a considerable force, but it had always been used for concealment in the rear. Although this was also very important, at the current stage, Ren Zhong hoped that they would deploy a portion of it over North China to offset the Little Devils' air force.
"We will do our best to fight for this matter," Chief of Staff Ye knew the stakes. Chief of Staff Ye deeply understood how strong the air force's suppression ability was on the ground.
"The second thing is, I need comrades lurking in the Little Devils' main airports to promptly pass on the intelligence about when the most warplanes are parked at the Little Devils' airports," Ren Zhong solemnly added.
"We will try to use our latest Dongfeng Express 1A rocket to conduct a long-range strike against the airports occupied by the Little Devils."
"What? Our long-range rocket has already begun to have strike capabilities?" Chief of Staff Ye said with some surprise upon hearing this.
"It's still difficult to evaluate the effect. The error in hitting long-range targets is still as high as 1000 meters. If there is a choice, I don't want to use this weapon now, but under the current circumstances, we have to try its strike capabilities," Ren Zhong explained.
The Dongfeng 1A already had a long-range strike capability of 900 kilometers. The circular probability error of the test firing attack had been reduced to a range of 1000 meters, which was still too large for targets like airports.
Theoretically, the Little Devils' current main airports in North China, including the Pingjin Airport, were all within the attack range of the Dongfeng 1A, but whether a long-range strike could accurately destroy the Little Devils' warplanes on the airport was a question.
Even in terms of warheads, the military workers had already improved the warhead's strike method according to the sub-munition method, completed the research on the cluster sub-munition warhead, and could now equip a ton of sub-munitions to launch an attack, with a single warhead's damage range exceeding 5,000 square meters.
Therefore, even if there was an error, this range of lethality could make up for it to a certain extent.
However, the killing of innocent people in the surrounding area was unavoidable.
Because this was a very pure area-killing weapon.
"This weapon is also very dangerous for intelligence personnel observing at close range. If possible, on-site intelligence personnel should immediately withdraw to a relatively safe area 3 kilometers away from the target after confirming the target," Ren Zhong reminded.
"No, we can't be too far away from the target, otherwise, we won't be able to carefully assess the effect of the strike. We will order the intelligence personnel to try their best to hide in the dug-out cellars near the airport," Chief of Staff Ye shook his head and refused.
"We spent a lot of effort, and even sacrificed many comrades, to exchange for an opportunity to sneak into a cellar 3 kilometers near the airport to observe the Little Devils' airport situation and return a lot of intelligence information. He will not leave the hiding place before the strike is completed."
Many things need to be done by someone.
As one of the most important defense locations for the Japanese devils, the airport was heavily guarded. To break through the numerous obstacles, dig a cellar near the airport, and infiltrate someone to conduct long-term observation...
This was an extremely difficult task.
Ren Zhong didn't know how they managed to do it.
It was just that such an opportunity only came once, and it needed to be carefully planned to maximize its effectiveness.
In the vast desert, five Dongfeng 1A missiles were prepared for battle.
Since Ren Zhong provided the latitude and longitude target of Yanjing Airport, Professor Qian and his team meticulously calculated how to use three Dongfeng 1A missiles to destroy the entire Yanjing Airport.
Theoretical calculations and on-site adjustments had been done several times, waiting for Ren Zhong's order. These three Dongfeng 1A missiles would pounce on the target.
Even though Ren Zhong had never said to always be in a state of combat readiness, Professor Qian and his team still maintained them with all their might every day, ensuring that these rockets could be launched at any time!
They could all hear the news from the front lines. Ever since Ren Zhong decided to use Dongfeng Express to launch an attack, Professor Qian and his team had been in a state of excitement.
Since this firecracker was developed, it had only been tested for accuracy. The warhead had never been tested with real stuff.
Because Ren Zhong felt it was unnecessary, there was a lot of test data in the main world to illustrate the strike effect of each warhead. A full ton of ammunition was not cheap. It was good enough to bring sand over; there was no need to waste it.
One ton of TNT could make hundreds of large-caliber shells. One 105mm howitzer shell, TNT, was just over 2 kilograms. If you tested 1 ton, you would lose more than 400 howitzer shells.
Now, the L105 howitzer has achieved large-scale mass production, with a marching weight of 2.2 tons, a full gun weight of 1.6 tons, a barrel length of 2310 mm (22 times the caliber), a caliber of 105 mm, an elevation angle of -5° ~ +65°, a direction angle of 45° left and right, a high-explosive shell weight of 15 kg, a muzzle velocity of 472 m/s, a maximum range of 11270 meters, and a rate of fire of 16 rounds/minute, almost replicating the performance of the M2A1.
The newest novels are first published on Liu Jiu Shu Ba!
Comparing the main performance of the Japanese Type 91 105mm howitzer, the full gun weight is 1500 kg, the marching state weight is 2137 kg, the barrel length is 2090 mm (20 times the caliber), the caliber is 105 mm, the vertical firing range is -5° ~ +43°, the horizontal firing range is 20° left and right, the maximum range is 10900 meters, and the firing rate is 6-8 rounds/minute.
The L105 howitzer can be said to have an overwhelming advantage.
In addition, because Ren Zhong improved the quality of the gun steel, the service life was increased from the original version of 5000 ~ 7500 rounds to more than 10000 rounds.
This time, when launching the Taiyuan Campaign, all four L105 artillery battalions accumulated on the border area were pulled across the Yellow River, becoming the trump cards of the Jin-Northwest Artillery Regiment and the Artillery Second Regiment.
It's just that now they are hiding and haven't taken action yet, surrounding the First Army in Taiyuan, waiting for the Japanese reinforcements to arrive. The Border Region Staff and the Eighth Route Army Headquarters have prepared a large-scale siege and aid operation for the Japanese devils this time.
Of course, from the current point of view, the fish that has been lured out seems to be a bit too big, and now it is a bit difficult to tame.
After three days of secret talks with Staff Officer Tongye, the intelligence personnel lurking near the airport finally sent back information.
"Pheasant returning to the nest, urgent."
In the agreed code names, the Japanese Type 97 fighter was code-named Hen, the Pheasant was the Zero fighter, and the Wild Chicken was the Type 1 fighter.
When these radio waves were transmitted to the Border Region Staff, they were quickly passed on to Ren Zhong and the Dongfeng Express team.
This time, Ren Zhong did not hesitate and immediately ordered the three rockets that had been prepared for launch to ignite!
Soon, three super rockets soared into the sky, and then adjusted their posture in the air and flew towards the distant target, entering level flight with a maximum flight speed exceeding 2210 m/s, which is an astonishing speed of Mach 6.5.
Even so, it was more than 700 kilometers from the base to the target, and it would take more than 6 minutes to fly from the base to the target according to theoretical calculations.
Therefore, after the rocket was launched, the next few minutes felt particularly long.
Professor Qian looked at the trajectory of the rocket disappearing into the sky, and couldn't help but feel a little nervous. In order to do a good job of this attack, he and the project team had verified it for several days.
From the precise measurement of the local latitude and longitude, to the confirmation and calculation of the Japanese airport's latitude and longitude, and the calculation of the coverage probability of rocket hit errors, each link was verified multiple times without error.
Even several young mathematicians from the Dawn Research Institute were mobilized to help verify—in the base, there are many mysterious computers that can very quickly use formulas and calculation speeds to verify the results of manual work.
As the most strictly managed computer room of the Dawn Research Institute, it is named the Jiuzhang Laboratory.
And those computers, in this time and space, have a Chinese name—Divine Calculator.
