On May 30, 1937, Tu Qianjun secretly arrived at a military camp on the outskirts of Fengtian City. Then the roar of emergency gathering and "fighting to the death" came from the military camp.

On June 5, the troops in this military camp quietly left here. No one noticed that another unit had been replaced here.

The various arsenals in the three eastern provinces have also increased their production efforts, especially artillery! The Chinese Defense Forces have seized many Japanese artillery during previous wars, including the Meiji 38th-year-old 105mm field cannon, the 91st-year-old 105mm field cannon, the 14th-year-old 105mm field cannon... and so on!

After these weapons are sent back to the arsenal, they will naturally need to be dismantled and studied, and at the same time, they will be continuously introduced and transformed. Now the three northeastern provinces can produce artillery of their own caliber, including...

The main reason why the 75mm artillery was willing to be sold to the Soviet Union this time is that the National Defense Force is preparing to change clothes. According to the research of Jia Xiaohou and others, after comparison, the caliber of the main artillery of the National Defense Forces has been determined to be 105mm.

At the same time, after a series of improvements, cost compression and technical improvements, this artillery has exceeded the original technical parameters of the Japanese army. The final result is the Liao 24-year-old 105mm howitzer!

For example, the Liao 24-year 105mm howitzer developed by the three eastern provinces was nearly three kilometers longer than the Japanese army's ten-kilometer range, reaching thirteen kilometers. The weight was hundreds of kilograms lighter than that of only 1053 tons.

It can be said that this is completely different from the artillery originally equipped by the Japanese army!

These technologies were built with the assistance of German and American technicians introduced by the National Defense Forces and the efforts of a large number of local R&D personnel in the three eastern provinces.

Now, four artillery factories in the three eastern provinces can produce 200 Liao 24-year 105mm howitzers and more than 120 150mm mortars per month! At the same time, if production is accelerated, it can also produce nearly 100 artillery with a caliber or above 100mm.

Now, the Fourth Legion stationed in North Korea has been fully renovated. At the same time, it is also strengthened, and 107 Tiger Roars are also used as mobile firepower. The individual firepower is mainly equipped with fire crows.

In the general factory of the Arsenal of the Three East Provinces, Tu Qianjun looked through the production information provided by the factory manager. At the same time, he listened to the report on his production and planned production.

"We don't have much time anymore, and the Japanese won't give us a lot of time!" Tu Qianjun slowly closed the report and said in a deep voice to Jia Xiaohou and others present: "The dressing must be completed as soon as possible! At the same time, urge the production of tiger rifles! Since the miniaturization has been completed, we need to step up the dressing! Also! The reserves of bullets are still insufficient, and the monthly output must continue to increase!"

Jia Xiaohou nodded, then Tu Qianjun said, "It's not that the output cannot be raised, it's mainly a problem of materials. If you can solve the problem of raw materials for us, we can at least half of the output! If the factory and equipment are added, it's not a problem to double it!"

Tu Qianjun nodded, was silent for a while and said to Jia Xiaohou: "I will find a way to deal with raw materials! What you have to do is to speed up production as much as possible. The soldiers on the front line are waiting for your weapons to kill the enemy..."

Everyone nodded, they knew that the burden was not light! With the newly built legion in Yunnan and Shaanxi, the National Defense Forces had more than two million troops! How many weapons would they have to be fully armed?!

In the three northeastern provinces, there are only four artillery factories and twelve gun factories. There are many involvement in this!

Tu Qianjun was preparing, and his opponent, Japan, did not relax. Since he tasted the firepower advantages of the National Defense Forces, the Japanese Army began to develop its own new artillery based on naval guns!

Type 90 240mm heavy cannon, plus 120mm heavy cannon, Type 90 240mm train cannon, Type 96 150mm heavy cannon, Type 96 240mm heavy howitzer... and a large number of heavy artillery weapons have begun to be put into the army!

At the same time, the Type 97 modified tank completed by the new design practice has also been mass-produced. This is a new tank developed by the Japanese army based on the Type 97 medium-sized combat vehicle. At least for the Japanese army.

This tank first strengthened the armor, from the original front armor 25mm to 50mm. At the same time, the side was strengthened to 30mm. The artillery continued to use the 57mm Type 97 gun.

The horsepower of the tank has also increased from the original 170 to 240! This kind of tank has been equipped with more than 400 units under the production of Mitsubishi Heavy Industries and Sagami Arsenal day and night! In addition to the previous Type 97, the Japanese army equipped a total of more than 1,000 tanks!

So the entire Japanese army was full of confidence in this! The newly promoted tank soldiers were ready to kill the so-called "invincible" tanks of the National Defense Forces on the battlefield! To cleanse the shame!

The Japanese army is modifying their tanks, and the National Defense Force is also modifying them. The tank troops originally stationed in Harbin have discovered a problem. Once winter comes, the tank will be launched and it will become very difficult.

Moreover, steel became extremely fragile under extreme cold. In order to solve this problem, Tu Qianjun asked Jia Xiaohou and others to develop an engine heater called "warm current".

This heater is integrated or naturally integrated with the engine cooling system, transporting heat through the cooling liquid to the heat replacement parts, and blowing evenly into the vehicle room through the existing air duct of the vehicle.

Using volatile technology, the ceramic ignition plug heats and evaporates the fuel into a gas state, ignites quickly and burns fully.

This heater is safe and reliable, and can be widely used on the basis of civil use, so it has been welcomed by everyone! After Tu Qianjun registered a patent in the United States, he made this technology civilized.

The winters in the three northeastern provinces are also extremely cold, and many civilian vehicles have been affected. This heater sells well, which makes the National Defense Forces R&D Institute make a small amount of money.

Secondly, Tu Qianjun introduced Erliton machine cannon!

There is probably no machine gun that can compare with the status of the Upper Swiss Erliton 20mm machine gun in World War II!

The 20mm machine gun designed by this Swiss company and its many derivatives from various countries were adopted by major participating countries such as France, Germany, Britain, the United States, and Japan in the mid-to-late 1930s. It constituted the main machine gun forces of various countries from the early to mid-20s!

A total of about 30 countries adopted the products of Ericon during the war, from the hot deserts of North Africa to the vast Pacific Ocean, the careful masterpieces of the Swiss can be seen everywhere.

The origin of the Erliton 20mm cannon can be traced back to the Baker cannon adopted by the Luftwaffe at the end of World War I, which was used as an airborne artillery and anti-aircraft gun. After the war, Simag purchased this design and made further improvements to create the "l" type cannon, which fired 20x99rb shells, weighed about 43 kilograms, and fired at 350 rounds.

Second.

Erliton then took over Simag and developed a heavier S-type cannon based on this, firing 20x110rb shells, weighing 62 kilograms, and firing rate of 280 rounds.

point.

This type of machine gun is so good that Tu Qianjun naturally wants to introduce it. Now the new Tiger Shark i fighter is equipped with the "Ban" 20mm*110 cannon modified based on this type of machine gun!

After modification, the loading volume reached 600 rounds! The rate of fire increased to 520 rounds.

Minutes! At the same time, the weight is reduced to 25 kilograms! Enough to be equipped on the Tiger Shark i fighter!

Then, Tu Qianjun applied for patents for these! He gritted his teeth, but Tu Qianjun did buy the production patent and also purchased the production line. On this basis, it was legal to directly apply for patents for modification and apply for patents in this era.

Tu Qianjun applied for a patent, which meant that Ericon could no longer produce products with similar performance. But Tu Qianjun was not a perfect person. After pulling Ericon's people to mutter for a while, the Swiss reported to the headquarters with a smile.

It was authorized to Erickon's "Bian" production rights, and in fact, the German Krupp also obtained this production rights. This was one of the conditions for Tu Qianjun to return for those national treasures.

As for the United States, it was authorized to Colt. As for the US Congress, Colt and others would handle Tu Qianjun themselves and ignore it. The only condition for Ericon, Krupp and Colt were that they could not be sold to Japan.

This made the Japanese grit their teeth and helpless. The Japanese Army was developing its own fighter jets, and the newly developed fighter jets of the Navy have also successfully tested the flights. After being equipped with a 7.7mm caliber machine gun, it was ready to mass-produce and equip the troops in 1938.

This aircraft is named "Zero carrier-based fighter" by the Navy and is numbered "a6m"! As the successor to the Type 96 carrier-based fighter!

Of course, according to the Japanese convention, the Navy concealed its fighter jets from the Army's horse dung. The Army continued to produce the Type 97 modified light bomber that they thought was already very advanced. This fighter jet was equipped with two 7.7mm machine guns. Of course, this was also the Army concealed the situation from the Navy.

At the same time, Nakajima Company also developed a fighter jet similar to the Navy for the Army and successfully tested the fighter jet. This fighter jet was named Nakajima... Hayashi fighter jet. But the generals of the Army felt that the Type 97 was advanced enough. Therefore, this fighter jet was not equipped.

In fact, the most important reason is that they have no money! In fact, the navy has no money anymore, so both armies are eagerly looking forward to the war!

Everything is being prepared in full swing! Nakajima...the Hayashi fighter was arranged to be produced until 1938.

The entire military headquarters is full of confidence. Tens of thousands of troops, more than 1,300 new 97-change fighter jets, were deployed to North Korea! In order to earn back the face he had lost!

The Japanese garrison in Tianjin quietly increased to more than 4,000! The number of Japanese troops in Qingdao also increased to more than 5,000 in silence! The number of Japanese troops in Shanghai actually increased to more than 6,000!

At the border between Fujian and various provinces, the number of Japanese troops stationed in the number of Japanese troops is also increasing! The war is about to break out!

,please.
