Wars compare comprehensive strength, not just population size and territory.

As an agricultural country, China will of course have to fall behind when competing with the small Japan that has completed industrialization.

However, in the Yongcheng base, Yang Tianfeng hopes to form a very high industrial development model in part. The continuous expansion of arsenals, the promotion of workshop-style processing and manufacturing, the support of civil iron smelting and coking, and the number of industrial populations gradually tends to catch up with the agricultural population.

In order to use limited land and a decreasing agricultural population to feed the military and civilians in the base area, fertilizers, humic acid, and scientific cultivation methods, it must be promoted and used. As long as the grain output is increased, Yang Tianfeng can expand his army more and support and train industrial workers more.

When high-rod crops grow, they are also called Qingshitang. The changes in the environment have brought guerrilla warfare into golden time. The Japanese devils' sweeps have just gone down and usually will not be launched in this season.

This gave Yang Tianfeng nearly two months to expand his troops and speed up training; while commanded by officers such as Chief of Staff Liang Moqing, he carried out large-scale guerrilla infiltration with the goal of the countryside. He devoted himself to military production and began to hoard ammunition and drug supplies, preparing for the battle in two months.

Yang Tianfeng did not care about the weapons and ammunition that had been finalized, but only asked Ou Hantao to continue to recruit workers and expand production; his energy was mainly focused on the imitation of 37mm anti-aircraft guns, the transformation of aircraft, the improvement of the slaughter saw, the pressing of copper clad steel plates and the homemade of bullet-rolling mills.

At this time, Yang Tianfeng really wanted to know the clone technique. Fortunately, the phone was connected, which allowed him to provide convenient guidance and saved him a lot of time and energy.

Experts and engineers from the rear came and went, and in exchanges and learning, many new technologies were adopted by factories and enterprises in the rear, and at the same time, the technical level and product quality of the base factories were improved.

In early July, two hull rolling mill production lines were finally completed, and the bullets made of copper clad steel plates were tested and met the needs of combat.

Compared with pure copper shells, steel shell bullets have greater wear on the rifle. In order to facilitate shell extraction, they must also be made into a large taper shape with the bottom edge. Therefore, Yang Tianfeng spent a lot of effort to develop copper-clad steel shell bullets to minimize adverse effects. Moreover, this is only the first step. When the quality of the steel can continue to improve, he is also preparing to produce painted steel shell bullets.

The copper-clad steel shell bullet saves more than 80% of copper material than pure copper bullets. That is to say, if one shell is recycled, the copper-clad steel is melted, and then the bullet is produced, one can be turned into four to five.

This means more ammunition for the three-sided vertical. Although the Tuwu Chain Saw (mg42) still does not reach the German stamping level and some parts still require lathe processing, it is not more expensive than the Czech style in terms of current manufacturing costs and time.

The arsenal in the rear can make rifles, Czech-made, Maxim heavy machine guns, and mortars. However, the arsenal in the base area has surpassed its technical level in addition to its scale and manpower. Of course, the technical level of the arsenal in the rear is also constantly improving, and under the urgency of wartime needs, the work production efficiency must also be greatly improved.

After the special production line was established, the chainsaw of Tuwu was now able to reach ten Nissan. Yang Tianfeng equipped most of its equipment to the Guo Detachment (also known as the direct guard regiment) and the Jiang Detachment, and also organized a urgent training class for machine gun shooters, and continuously transferred equipment and supplies to Luyi to prepare for the battle on the Western Front.

Before deciding to equip the troops with the Japanese chain saw, the arsenal director Ou Hantao told Yang Tianfeng with concern that if this machine gun is seized and copied by the Japanese, the consequences will be very serious.

Yang Tianfeng did not explain much about this amateur’s concerns, but just asked a question with a smile, “Does the design of the gun be based on the bullet or the original structure of the gun be used to cooperate with the bullet?”

In fact, there are not only one who made such a mistake. At the end of World War II, the Americans, who hated and feared mg42, had a pragmatic and reverse thinking attitude, naively thought that they would match their own. The 30-06 bullet could create a machine gun that was more powerful than mg42, and was tentatively named the t24 universal machine gun (the prototype weapon was coded with t and was changed to m after it was officially in service), and was carried out by the company Saginawsteeringgear.

It is a bit naive to say that this idea is a bit naive. The 30-06 bullet charge is 0.34cm³ more than the 7.92mm Mauser bullet; maybe you don't think it's much, but without changing the original structure and design, the extra one-and-a-half-point gunpowder makes the t24 machine gun crazy than the North American Mustang when it is fully automatic. Finally, the US military is very sensible and wisely put this plan on the shelf and regards it as never before.

Any industrialized country has established its own military-industrial system according to its own war philosophy and industrial characteristics, forming weapons standardization, ammunition unified and serialized to make logistical support strong.

Therefore, all countries have excellent weapons. For example, Czech-made light machine guns, mp40 submachine guns, mg42 general machine guns, Geggarev light machine guns, Poposa submachine guns, etc., but there is no army that "learned with all the strengths", except China uses "Made in All Nations".

Of course, Yang Tianfeng did not rule out that the Japanese chainsaw was captured by the Japanese, nor did he rule out that the Japanese would imitate it, but this possibility is very small, so there is no need to worry about this. In particular, the Japanese army has begun to equip the Type 96 light machine gun, using 77mm bullets, and believes that the Type 92 heavy machine gun has excellent performance, excellent maintenance and considerable lethality, so it is even less likely to produce other bullets and need to be replaced on a large scale.

The reason why Yang Tianfeng was eager to equip the Japanese chainsaw was that the Maxim water-cooled heavy machine gun in the army was too bulky, and the machine gun bunker was easily discovered and destroyed, and could not suppress the Japanese Type 92 heavy machine gun; although the Czech Republic was good, it had only twenty magazines, which was also at a disadvantage in continuous firepower compared with the Japanese Type 96 light machine gun.

The production and manufacturing of new weapons and new ammunition undoubtedly means that the arsenal has made a breakthrough, but a bigger breakthrough is the beginning of the process of homemade machinery and equipment. The successful manufacturing of stamping machines, plate rolling mills and shell rolling mills undoubtedly increased the output by several levels.

The purchase of precision lathes, the improvement of production technology, and the successful preparation of fierce gunpowder have also spawned other weapons, to be precise, other ammunition.

The 12.7mm penetration ignition warhead has no detonator, and it is only equipped with violent explosives. The basic structure consists of the warhead shell, lead sleeve, steel sleeve, bullet core, combustion agent, explosives, and combustible materials.

When the warhead penetrates the thin steel plate at a certain speed (equivalent to the skin of the aircraft), on the one hand, the steel plate is deformed and destroyed. On the other hand, the front end of the warhead is squeezed and deformed, while at the same time, the combustion agent and explosives are squeezed.

When the violent gunpowder is impacted, it forms a hot spot and detonates the explosive. The explosion of the explosive starts from these points and expands until all the explosives explode. If the impact of the warhead causes the combustion agent to burn first, the combustion flame can also turn the explosive from combustion to detonation.

It can be seen that the production and manufacturing of explosive and explosive warheads is relatively complicated, and it is not equipped for general troops, but is specially equipped for air defense weapons or fighter jets.

The successful development and production of the 12.7mm explosive bomb was also the world's leading position at that time. The arms experts at that time once calculated that even if the 50mm bullet was loaded with explosives, it might not have enough power to destroy the armor. Therefore, it is believed that only shells above 20mm were suitable for designing blast bombs.

The reason is very simple, miniaturization of the signal tube is a problem. The United States has experimented with various 12.7*99 armor-piercing bombs, but the fuses are not up to standard, so it is not equipped with armor-piercing bombs for the Browning M2. The British asserted that only warheads above 20 mm are suitable for equipting blast bombs. This is also related to this.

The successful preparation of fierce gunpowder easily solved this problem. If you want to effectively destroy enemy fighter crews hiding behind defensive armor, engines and fuel tanks, the most effective method is to use blasting bombs or even armor-piercing blasting bombs.

Another type of ammunition is a mortar incendiary bomb, which is divided into 82 and 120. Incendiary bombs naturally contain less explosives, while incendiary is also filled with another. However, this incendiary bomb is still far from the solidification*******, which has not yet been released.

Although humans have long used fire as a weapon and applied to the battlefield, the liquid combustion agents used (such as the fuel of flamethrowers) have a major problem. This substance is easy to splash and difficult to adhere, and it is difficult to achieve the purpose of concentrated killing. Later, scientists discovered that switching to gelatinous gasoline can increase the range and effectiveness of flamethrowers, but gelatinous gasoline needs to be used to use natural rubber with high demand and expensive demand, which is difficult to manufacture.

It was not until the late World War II that a group of chemists in the United States developed cheap gasoline viscosist and further proposed the formula for mixing the viscosist and gasoline, so that the mixture could burn at a specified rate and adhere to the object. The solidification ******* was born and used in large quantities in subsequent wars. However, Japan became the first "beneficiary".

Of course, Yang Tianfeng knew the composition of gasoline viscous agent and the mixing ratio formula. But based on actual conditions, he could not make it immediately. He had to wait for the coal chemical factory to make further breakthroughs and produce the chemical supplies he needed.
