"We found out."

On the runway behind Zhao Jiayu Machinery Factory, the person in charge pointed to three planes and said:

"Because of the speed, the hit rate of frontal shooting on the flying platform is not high, and if you want to improve the hit rate, you can only reduce the altitude, but this will increase the danger of the flying platform."

Flying platform, this is naturally a noun heard from the mouth of the master.

Zhao Gang and Li Yunlong nodded in agreement.

It has been half a year since the formation of the flight brigade.

There are no limits to the number of aircraft, there is no limit to the supplies, and the number of pilots is steadily expanding.

In the previous battle between Henan and China, the flight group carried out large-scale air support, taking off more than 6,000 sorties, dropping more than 12,000 tons of bombs, and firing more than 3 million rounds of 30-mm cannon shells.

But the actual combat effect was not good.

Especially for the cannon strafing, the response of the liaison officers observing from the ground was very poor, and most of them only heard a sound.

Although the effect of the heavy fragmentation bomb is good, and the steel balls sweep a large area, the persistence is too poor, and it is difficult to ensure the continuity of firepower because an aircraft can carry a dozen bombs at most.

Other than that.

According to post-war statistics, the vast majority of downed planes occurred during the dive attack.

Thanks to the extreme scarcity of anti-aircraft weapons for the little devils, the domestic troops are particularly stretched, and even most of the first army is not equipped at the wing level, so the number of downed planes is not large.

"But side shots are completely different."

The person in charge continued:

"Placing ground support firepower on the side of the aircraft will greatly improve the accuracy of ground attack."

"Take the 12.7mm machine gun as an example, install it on the flank of the transport aircraft, and test it at the actual shooting range, even at an altitude of 2,000 meters, a trained and excellent shooter can be prepared to hit a target with a radius of one meter."

"And the hit rate is as high as one in seven."

"Two thousand meters, 12.7 heavy machine guns, one in seven hits?"

Hearing this, Li Yunlong was shocked.

What does a seventh-miss rate mean, that is, for every seven rounds fired, one will hit the target, placed on a target at a distance of two kilometers, a radius of one meter, and a machine gun with a high rate of fire, which is quite a top-notch shooting effect.

You must know that the 12.7 mm heavy machine gun has a straight range of only 1,800 meters.

"Great."

Li Yunlong couldn't help but wave his hand fiercely.

The 12.7 mm heavy machine gun was a meritorious weapon in the regiment.

The power is huge, as long as any devil hits a shot, he will either die or be disabled, there is no second possibility, and it can also penetrate the standard sandbag bunker, and the suppressive force is extremely strong. The fire is fierce, the rate of fire is as high as 500 rounds per minute, the trajectory is straight, and the maximum range is 1,800 meters. It is the most effective timely suppression of fire by infantry.

But now, this weapon is a little embarrassing on the front line.

The reason for this.

This thing weighs more than 60 kilograms, and there are nearly 30 kilograms in the disassembly, and there are big mules when marching, which is not a big problem, but when fighting, it can only be carried on the shoulders of soldiers, and it is very inconvenient to transfer the front-line position.

The firing range of 1,800 meters is not enough before the firing range of long-range howitzers is more than 10 kilometers, and the firing range of mortars of various calibers is 2 to 6 kilometers. With recoilless guns, anti-tank, anti-sandbag bunkers will not be able to make their turn.

As a result, during front-line battles, this thing is actually not as popular as the general-purpose machine gun, and the number of equipment is gradually decreasing, although the armored vehicle is also equipped with this machine gun, which can provide fire support to the troops at any time, but the armored vehicle movement is limited, and the firing range is also severely limited.

Now it is possible to equip transport aircraft with such machine guns.

The condescending field of vision, the perfect shooting range, the timely support, the two-thousand-meter distance and one-meter radius of the target hit rate one-seventh, the accuracy is extremely high, more than five tons of load, and the firepower is long-lasting.

The perfect infantry support weapon.

And the little devil still lacks anti-aircraft weapons, when the time comes, let the attack plane destroy the poor anti-aircraft cannon of the little devil, and then let this thing enter.

Thinking of this picture, Li Yunlong was a little impatient.

"How many planes can be produced before the fifteenth?"

"Can I put other weapons on it as well?"

Li Yunlong hurriedly asked.

In the next campaign of the First Army of the Total Annihilation, three or five were useless, there had to be a certain number, preferably dozens of them, and the 12.7 mm machine gun was a little worse, if the 20, 40 or even 75 guns could be brought up, it would be perfect.

Heavy bunkers can defend against 12.7mm machine guns, but against 20 and 40 guns.

"This is very simple, start work at full speed, and you can modify five planes a day."

The person in charge continued:

"As for the other weapons, we have tested them all. Except for the 105 guns, which could not be loaded with accidents because of the recoil, the rest of the 20 anti-aircraft guns, 30 machine guns, 40 anti-aircraft guns, and 75 mountain guns could be loaded on the plane. ”

"Okay."

Li Yunlong was overjoyed.

Then the two came to the airport in Heyuan County.

Here, Huang Quanzheng led the team to organize training, and the training subject was dive bombing.

The five best pilots of the Independent Regiment, of course, are also the best pilots in the whole army, these five people, the average flight time is as high as 2,000 hours, and it is also the flight time after coming to the Independent Regiment.

At this time, the five people were driving a bomb truck, loaded with more than a ton of ground-penetrating bombs, diving from a height of more than 2,000 meters, and then accurately hitting the fortress.

The intelligence department has recently heard that near Taiyuan, the devil organization has built a lot of solid concrete bunkers, with a maximum thickness of three meters, and the little devil seems to have made up his mind to defend it.

When the time comes, this kind of ground-penetrating bomb will be needed to solve these permanent fortifications.

In Li Yunlong's sight.

The five planes took off in turn, flew to an altitude of several thousand meters, and then began to dive towards the ground, and finally the bomb accurately hit the three-meter-thick concrete pillbox on the ground.

Visible to the naked eye, the bomb went straight into the fort, first with a brief silence that made one wonder if it was a dud, and then the explosion suddenly soared, kicking up a cloud of concrete debris.

"Not bad."

Li Yunlong was overjoyed when he saw this.

The training of the independent regiment, of course, has to be live-fire training.

Bunkers are real people, and bombs are real people.

The all-concrete bunker is three meters thick, and the amount of cement and steel bars is only a lot more than that of the devil, since the fortress in front of him can be directly overturned by the ground-penetrating bomb, then the devil has no problem.

"Then I will prepare manpower and place to accept six factories and masters."

Zhao Gang also said with a smile.

Now not only Ping'an County, Heyuan County, Pan County, Shou County, Zhao Jiayu these locations, the independent regiment has more territory, dozens of large and small counties belong to the independent regiment base area, and the railway highway between them is also in full swing construction.

These factories can be planned well.

In the end, he even urged:

"Hurry up."

"Okay."

Li Yunlong laughed.

······

Time passed, and soon came to June 14th.

By this time, Kong Jie had gained a firm foothold in the south, expanded his base with the local guerrillas, built runways, and began to transport supplies on a large scale.

In the beginning, the independent regiment dispatched twenty transport planes to start transporting supplies at a rate of 100 tons per day, and after the expansion of the airport, it began to gradually increase the volume of transportation, and finally maintained the size of a transport brigade, that is, 54 transport planes, about 250 tons per day.

Of course, taking into account the influence of the weather, it is actually about two hundred tons per day.

But there are no less.

Since there was no decent enemy, there was basically no shortage of weapons, equipment and ammunition, and most of the transportation was food and supplies, mainly grain, which was more than 150 tons per day.

During this period, if there is food, it is the uncle.

In the face of the high-quality grain airlifted, coupled with other daily necessities and commodities produced in the base area, as well as the strong combat effectiveness of the troops, the influence of the local tyrants and squires was not afraid at all, and they were quickly trained to obey.

The base area expanded rapidly, and the influence of the troops also increased greatly, and they soon won the strong support of the local people.

Kong Jie did not take the initiative to make trouble, but slowly expanded his territory, expanded his influence, expanded the airport, built warehouses, stored materials, and recruited troops, planning to form a 10,000-person army before going out.

At the same time, the entire land of the Republic of China is still in full swing.

In the south, under the command of Yokoyama Yong, the devils were like a bamboo, all the way to Nguyen Jiang, Yi Yang, Liu Yang and other places, and once again began to mobilize troops to prepare for the attack on Chang Sha.

But before attacking Changsha again, Isamu Yokoyama hesitated:

"A group of guerrillas with strong combat effectiveness appeared? Moreover, traces of the take-off and landing of a large number of transport aircraft were found. ”

"Suspected to be a unit of the Independent Regiment!"

Looking at the news in the telegram in front of him, his brows immediately furrowed, and his heart was even more sudden.

Yokoyama Yong had a good personal relationship with Gangcun, and in a recent phone call, he learned about the tragic situation of the North China Front at this time.

After the Battle of Central Henan, although the North China Front suffered few casualties on the surface, it was actually crippled, most of the new recruits were replenished, heavy equipment losses were huge, and the overall combat effectiveness dropped by 50%.

All this was due to the air strikes of the aviation units of the separate regiment.

According to post-war statistics, the Independent Regiment carried out more than 6,000 air raids in just one month, dropping more than 12,000 tons of bombs.

And now, the appearance of aviation forces suspected of being independent regiments in his rear, that is, in northeastern Hunan and northwest Jiangxi, can't help but make him highly vigilant.

Although his recent offensive has been overwhelming, and the base camp commendation telegrams have been continuous, there is a hidden crisis in the big victory.

Not long ago, the Imperial Air Force was heavily damaged by the Independent Regiment, many airfields were bombed, planes were also bombed, and the air power was almost destroyed, resulting in the fact that he now has hundreds of thousands of troops under his command, and there are almost few planes capable of fighting.

Therefore, during this period of time, the Sino-US joint flight team was dispatched in a big way, although it failed to affect the overall battle situation, after all, the number of planes was too small and the supplies were insufficient, but under the air raid, his losses were not small.

Of course, it is far less serious than that of the North China Front.

But if the independent regiment is dispatched at this time and gives him the same air support as during the Battle of Central Henan, 6,000 sorties of bombing, and 12,000 tons of ammunition, then...

Thinking of this, Isamu Yokoyama's fat face trembled.
