At about 3 o'clock in the afternoon of the 23rd, the tragic Songhu air battle officially ended.

The vigorous Songhu landing operation was defeated by the Huaxia Air Force before it really began.

Tens of thousands of Japanese troops preparing to land in Songhu had no choice but to continue to drift in the East China Sea, especially the aircraft carrier, which was regarded as the supreme treasure of the Japanese army, was even more painful after being blown up and seriously injured.

Japanese Navy Minister Mitsumasa Yoneuchi, at the subsequent joint meeting of the base camp, angrily accused the front-line commanders, "The navy is the foundation of the imperial state, and if the elite of the navy is compromised for the sake of a little profit, it will bring unnecessary risks to the safety of the Japanese Empire, and this is a crime against the Yamato nation.

How big were the losses in the Songhu air battle?

China and Japan were secretive until the end of World War II.

Military experts from the outside world also have different opinions, believing that the statistics of China and Japan are not credible, mainly because of the aviation technology problems at that time, and most of them judged that the fighter planes in 1937 would never be able to sink the aircraft carrier.

On August 24, 1937, Nanjing held a press conference in Shanghai.

The results of the Songhu air battle announced by the Huaxia side were: "The Huaxia Air Force damaged and shot down more than 400 Japanese fighters, including 189 in the Type 96 land attack and 223 in the Type 96 ship battle." In addition, it sank a number of Japanese warships, including the Akagi and Kaga, and five cutting-edge aircraft carriers."

On the contrary, in this battle, Huaxia's losses were relatively small, well, for example, there were less than 200 fighters, including 126 Flying Leopard fighters, 57 Flying Bear heavy fighters, and a number of air defense facilities on the ground.

It was only at this time that the whole world knew that the Chinese Air Force dared to fight and could fight.

Moreover, there is also a cutting-edge heavy fighter in China, codenamed "Flying Bear", which means "Flying Tiger" in ancient times, so the Japanese army also called this type of fighter "Tiger" fighter, which means extremely ferocious and bloodthirsty.

Since then, various major powers have developed heavy fighters, especially Germany, which launched the BF-110B fighter in December 1937.

The fighter has an empty weight of 3.8 tons, a maximum take-off weight of 6.6 tons, two engines that can provide 2×1200 horsepower, a maximum speed of 610 kilometers, an altitude of 10,000 meters, a range of 1,600 kilometers, and is equipped with two 20 mm cannons and four 7.92 mm machine guns.

On August 26, the Japanese army headquarters submitted a memo to the emperor, saying, "In the air battle at the mouth of Shanghai, the navy and land air forces were brave and good at fighting, and the fighters added 20-millimeter aerial guns, and the air warriors shot down the Chinese fighters, just like shooting targets in the field, and shot down nearly 300 enemy planes, including 195 Leopard fighters and 96 Tiger fighters, and the imperial kingdom won an unprecedented victory."

In any case, the battle on August 23 caused extremely heavy losses to the Huaxia Air Force.

What is even more regrettable is the loss of elite pilots, the pilots in western Sichuan alone have lost more than 100 people, if it were not for the submarine to rush to the combat area in time and rescue more than 30 pilots in time, I am afraid that it will make matters worse.

In this big air battle, a large number of combat heroes appeared.

Yan Haiwen, the pilot of the Fifth Brigade, was unwilling to be captured after parachuting because the fighter plane was shot down, so he shot himself.

Detachment leader Shen Chonghai and bomber Chen Xichun took the initiative to ram into the Japanese warship due to a malfunction of the landline.

Wang Tianxiang, captain of the Fourth Brigade, Qin Jiazhu, commander of the detachment, and pilots Wang Zhikai, Zhang Juncai, Hong Guanmin, and Chen Xiongji, as well as pilots Wang Zhikai, Zhang Juncai, Hong Guanmin, and Chen Xiongji, were still entangled with enemy planes in order to allow the bomber group to successfully attack the Japanese aircraft carriers.

Although the losses of the Japanese army were even heavier, their pilot base was large, and the manufacturing industry of ships and aircraft was relatively developed, and this loss would soon be recovered, and the savings of the Huaxia Air Force in the past ten years were almost half of them.

Therefore, in general, it was the Chinese army that suffered a big loss.

However, from then on, during the entire Battle of Songhu, the Japanese fleet of ships no longer dared to come within 100 nautical miles of the battle area of Shanghai, resulting in the Japanese army only relying on their meat bullets to capture Shanghai.

Even General Sugiyama Moto, who was the land minister of the Japanese army at the time, prepared for the worst, and was prepared to suffer the casualties of a million imperial troops in order to win this holy war.

When the Japanese plane was searching for and rescuing the pilot, it accidentally discovered the traces of the Huaxia submarine and transmitted the news back to the base camp in time.

As a result, Prime Minister Fumihiro Konoe, Umi Miguang Interior Minister, and Land Minister Sugiyama Moto, among others, could not help but be very worried and suspicious, fearing that submarines would attack their transport fleet, so they had to strictly order Matsui Ishine and other front-line commanders to carry out landing operations as soon as possible, and at any cost.

At three o'clock in the morning of the 24th, the Japanese army launched a landing at night.

The Japanese Shanghai Dispatch Army, under the command of its commander, General Matsui Ishone, consisted of the 3rd, 9th, and 11th Divisions, as well as elite units such as the Taiwanese Shigeto Detachment, and simultaneously seized the beach at Wusongkou, Pudong, and Chuanshakou.

The Huaxia army did not sleep either, and was already in full battle.

Before the Japanese army's beach-grabbing death squad could gain a foothold on the beach, they were intercepted by the Huaxia heavy artillery group, and the Japanese troops who grabbed the beach were bloodied, killed and wounded, and even lost more than half of the various beach-grabbing boats.

In desperation, the Japanese army had no choice but to set up artillery desperately and counterattack the artillery positions in Huaxia, even if it was blown up and wiped out, it had no choice but to admit it.

It was not until dawn that the Japanese transport fleet gradually withdrew from the beach-grabbing area, and the 100,000 Japanese troops still did not penetrate deep into the land.

It has to be said that the quality of the Japanese soldiers at this time was really high.

They soon set up improvised positions in various beachhead areas and engaged in a zero-distance desperate battle with Zhang Fakui's Eighth Group Army, Zhang Zhizhong's Ninth Group Army, and Chen Cheng's 15th Group Army and other anti-landing forces.

Despite the absence of aircraft, heavy artillery, and naval guns, the battle for the various landing beachheads was still very bloody.

Tens of thousands of machine guns and mortars have formed a series of beautiful "landscapes", but these scenery lines are a little cruel, and as far as the eye can see, they are all severed heads and stumps, and all flesh and blood are flying, and the Chinese and Japanese sides are lying like hemp on each beachhead, like hell on earth.

What really relieved the Japanese army was that it may have been due to the short-handed encounters between the two sides, which caused the heavy artillery clusters in China to no longer exert their might.

This is not the case, mainly because the heavy artillery shells have been cut off, and the shells brought from the rear are too dangerous, not only can they not be used normally, but also cause many heavy artillery pieces and their artillery to be blown up by inferior shells, and the high-quality shells transported from western Sichuan are still on the way.

When Jiang Weizuo received the news, it was already very late.

He was in a hurry on the Purple Mountain, and scolded several words in a row, but unfortunately to no avail, who called Huaxia's industrial foundation weak. In desperation, I remembered the arms king of western Sichuan-Major General Liu Yicheng.

This guy is already a well-known arms expert in the Republic of China.

However, it remains to be seen whether he will be able to make the Jinling Arsenal, a cutting-edge ammunition production base, produce qualified heavy artillery shells.

However, the matter was in a hurry, so he had to treat the dead horse as a live horse doctor.

Major General Liu was soon summoned to the Jinling Arsenal, and the old Jiang pointed to the mountains of inferior shells with a black face and a cane, and asked this guy to quickly think of a way, completely ignoring the face of the bureaucrats, and immediately appointed him as the special commissioner of the factory to supervise the heavy artillery shells.

Due to the urgency of the front line, Lao Jiang was really anxious this time.

He not only dispatched a brigade of Chinese military police to the Jinling Arsenal, but also ordered He Yingqin and other directors of the Ordnance Industry Administration to personally grasp production and ideology, "Anyone who deliberately cheats and cheats will be served with a military stick, anyone who deliberately sabotages the production will be shot and sitting, and anyone who derelicts his duty or eats and takes advantage of cards will be sent to the military commander for severe torture."

The discipline of the entire Jinling Arsenal was suddenly abruptly sober.

However, the technical experts of the military factories have also become conscientious and have shrunk their work, and the actual production capacity has been greatly reduced.

Liu Yun didn't bother with these for the time being, but randomly sampled, picked up a few inferior shells, and asked the brain to scan them one by one, and carefully study these inferior shells in the virtual illusion.

As the saying goes, "the bell must be tied to the bell", and the root cause of inferior shells must be found from the shells themselves.

Later, he went to the production workshop for an in-depth investigation, looked carefully inside and outside the factory, and talked to some old military workers one by one.

But in the final analysis, it is due to the weak industrial base of China.

Because the artillery shells produced by the Huaxia Arsenal for a long time are 75 mm shells, and more than 100 mm are relatively rare, and now let them produce large-caliber shells, it is really a bit of a duck to put on the shelves, taking 122 mm shells as an example, the bullet weighs more than 30 kilograms, and it has to be divided into 0-9 dosing, which is really complicated.

Because a small 122-mm shell, not only the material itself is exquisite, but also divided into warhead, body and bottom pad, but also to consider the large and small medicine packs, as well as the overall tolerance, especially the overall tolerance.

Generally speaking, the more intermediate links, the greater the final tolerance value.

Due to the lack of basic industry, the technicians of the Jinling Arsenal did not think about the tolerance problem at all, and the war was urgent, and the commander above urged him to hurry, so after piecing together the mold for a while, he was directly transported to the front line, if there was no problem, it would be really strange.

Once you've found the cause, the rest will be easy.

The shells in the arsenal are relatively easy to handle, and all kinds of facilities here are relatively complete, and those that can be corrected can be corrected in time, and those that cannot be corrected can also be scrapped directly.

Only the shells that have already been sent to the front are a little troublesome.

I want to transport it back, but I am afraid that there will be an explosion accident on the way, and even if it is really shipped back, when everything is handled properly, and then transported to the front line, there is still a shadow in the hearts of the front-line soldiers.

Fortunately, Liu Yicheng is from the 21st century, and he has seen countless immoral methods on the Internet, such as transforming large-caliber artillery shells into heavy mines, bombing tanks and soldiers, which is really vicious, not to mention that there are experts from the arsenal who help them come up with bad ideas, and they have taught countless children badly.

After a period of busyness, tens of thousands of modified mines were planted in war zones such as Wusong, Baoshan, and Luodian.

Jinling Arsenal is a newly built arsenal in the 30s, and Nanjing's old Jiang and He Yingqin and others have invested a lot of effort in this factory.

Theoretically, in 24 hours, more than 1,000 heavy artillery shells could be manufactured, of which 800 were 122-mm shells and 200 were 152-mm shells.

Commissioner Liu's method is very simple, that is, to adopt the method of the Americans to make cars, that is, to adopt "assembly line operations", and the professional division of labor is more detailed, such as the manufacture of 122 mm warheads, from pouring the inverted mold to the final grinding and polishing, a total of 29 processes are divided.

In addition, when manufacturing spare parts, try to replace manual work with machinery and equipment, because the advantage of manpower is flexibility, and the advantage of machine is uniformity, so that the specifications of the finished product are more uniform and standardized.

What's more, "uniformity" can not only reduce the tolerance of spare parts to the minimum, but also speed up the production of products, when Liu Yicheng completely adjusted the production process of artillery shells, the output of heavy artillery shells reached 1,500 pieces per day, barely reaching the minimum demand of the front line.

The three days passed quickly, and the Jinling Arsenal was basically adjusted.

The supply of large-caliber artillery shells has finally returned to normal, especially with the help of ant robots, nearly 10,000 inferior artillery shells have been corrected one by one, and they can be officially sent to the front line in Songhu to support the Chinese artillery to fight the Japanese devils.

Three days, for military production, is simply negligible.

However, for the front line, it was completely dire, because the Japanese troops who had landed had gained a firm foothold and were attacking the deep positions in the Songhu area, and by August 27, the Japanese advance had approached Luodian and Yuepu.

Moreover, because the Huaxia Air Force suffered heavy losses in the Wusong air battle, the Japanese army also found the best way to deal with the Huaxia fighters, that is, a war of attrition, using a steady stream of aircraft groups to take turns to engage in battle, and continuously depleting the Huaxia air force.

From 25 August, more than 10 or 20 fighters of the Huaxia Air Force were consumed by the Japanese fleet every day.

By August 27, even the daily patrols had to be careful.

Although the newly arrived Japanese aircraft carrier group no longer dares to be as bold as before, and plays with its character at every turn, it is undeniable that the Huaxia Air Force has gradually lost air supremacy in the skies over Songhu, and the losses of the Huaxia Army are getting heavier and heavier.
