When launched, it rains down on the target like a volcano erupting hot magma; The sound was like thunder and tiger roaring, and the heat was overwhelming, not only destroying a large number of living forces and military equipment of the devils, but also giving the devils a huge shock to their spirits.

Yang Tianfeng held the telescope and didn't put it down for a long time, imagining the power of the rocket artillery when it was put into actual combat, and fantasizing about the tragic situation of the devil.

Ou Hantao scratched the hair of the messy canopy, and he was also excited. The successful manufacture of every new weapon is the result of his painstaking efforts and that of the technicians and workers, and every victory at the front line also has their contributions and credits.

"Manufacturing, hoarding, and special ammunition vehicles, in the short term, our army may not use rocket artillery in actual combat." Yang Tianfeng put down the binoculars and said something that made Ou Hantao a little disappointed.

But Ou Hantao was relieved, although the arsenal has been expanding, from machines to personnel, from completely purchased equipment to partially self-made, it has developed rapidly. But compared with Japan, an industrialized country, it is still 108,000 miles behind. Some weapons can be used, and some weapons can be copied with serious consequences.

Therefore, when rocket artillery and rockets are hoarded to a certain order of magnitude, Yang Tianfeng may be used in actual combat. Or if the situation is very critical, then naturally there is no need to worry about the consequences.

"The recoilless cannon should work, right?" Ou Hantao said tentatively: "The Japanese devils have a lot of direct-fire artillery and heavy artillery, so they shouldn't be reluctant to go far and bother to make this kind of weapon, right?" ”

"Actually, you can use it, but you have to get the timing right." Yang Tianfeng smiled and patted Ou Hantao's arm, "Germany has recoilless guns, and the United States will also have them, but in terms of performance and quality, ours is the most mature and the best." ”

In World War II, the German recoilless gun was designed to provide the airborne troops with a kind of heavy support firepower that could be obtained quickly, so it mainly equipped paratroopers. The German recoilless gun is technologically advanced, has a long firing range, high accuracy, easy disassembly, and flexible maneuverability. It is the best weapon for paratroopers lacking heavy firepower and mountain infantry with difficulty in maneuvering.

For Yang Tianfeng, who is accustomed to using the doctrine of borrowing, the drawings he came up with were borrowed from the advantages of the German 75-mm LG40 and the American M20 75-mm recoilless gun. The final cannon weighed 53 kilograms, had a caliber of 75 millimeters, and had a direct firing range of 500 meters on a bipod, 800 meters on a tripod, and a maximum firing range of more than 6,000 meters.

That's right, the recoilless gun can fire straight or curved fire, can fire armor-piercing shells to attack armored targets, and can also fire high-explosive grenades to kill enemy living forces. Therefore, it can be used as a company-battalion level support artillery, and it is very powerful.

It can also be seen from various indicators that the recoilless gun is much higher than the steel fist in terms of range, and the power is also greater, and it is relatively safe to deal with the devil's turret and pillbox. Moreover, with the improvement of the steel process, the weight of the gun is likely to decrease further.

Yang Tianfeng was more pleased not with the success of the manufacture of new weapons, but with the technological breakthrough and progress of the arsenal. From the imitation of the Browning 12.7mm heavy machine gun, to the Soviet 37mm anti-aircraft gun, to the manufacture of 75mm recoilless guns, with the help of new machinery and equipment, and also thanks to the progress of processing technology, the production of rifled guns and artillery has finally taken a milestone and a major step.

Ou Hantao didn't understand the timing of what Yang Tianfeng said, and he didn't want to understand, anyway, sooner or later it would be used to fight devils, and that would be enough. At the same time, every time Yang Tianfeng takes out a drawing material, it is a challenge for him and the technicians, and it is also an accumulation and progress of knowledge and technology, which he is never tired of.

In addition to the demonstration of rocket artillery and recoilless guns, Yang Tianfeng also saw the experimental effect of air-blown artillery shells.

Although there were still great difficulties in the production of radio-type air-bombed artillery shells, they did not prevent the creation of a simple one against infantry. A spring-like anti-throw device is installed in the front of the shell and connected to the delay fuse of the shell. When the shell lands, it triggers the lead and jumps back into the air to explode, greatly increasing the radius and effect.

If the warhead of the artillery shell is filled with the newly developed mixed explosives and prefabricated steel balls, the explosive power of the shells of the 82 mortar can actually approach or exceed that of the ordinary 120 heavy mortars, and the power of the 120 heavy shells is nearly twice as high.

On the one hand, it is to develop and launch new weapons, and on the other hand, it is to dig deep into the potential of existing weapons and ammunition.

At the same time, his data output and technical exchanges have also greatly promoted the improvement of the rear production technology.

For example, the 28th Factory of the Ordnance Industry Administration has not only made tungsten die steel, but also made breakthroughs in special alloy steel, machine gun barrel steel, non-telescopic steel, stainless steel, spring steel, and special alloy castings. In addition, the 24th Factory of the Ordnance Industry Administration has successfully developed chrome barrel steel, which is widely used in the manufacture of medium and formal rifles.

These achievements in the metallurgical industry are inherent in history, but with the help and promotion of Yang Tianfeng, they have greatly advanced the schedule and more effectively supported the war of resistance at the front.

And Yang Tianfeng, or the arsenal, has also benefited greatly from these scientific and technological advances, saving a lot of time for research experiments.

In other words, it's a mutual push and boost. For example, the 12.7mm heavy machine gun uses a new technology with a chrome barrel, which makes it more reliable and wear-resistant.

"The technical research team has another task." Yang Tianfeng smiled bitterly with some apologies, "I always keep working for you and compressing your rest time." But this is also a thing that can't be helped, anti-Japanese ........."

"Commander, don't be so polite." Ou Hantao not only did not look embarrassed, but also felt excited, "We are hiding in the rear, eating and drinking without worry, and the treatment is higher than those soldiers who are fighting on the front line, which is already uneasy." If you are more idle, you really can't talk about it. ”

"Okay, then let's not be polite." Yang Tianfeng took out a stack of paper from his briefcase, which was full of drawings and various marks.

"The Commander is working harder than we are." Ou Hantao sincerely admired, "You also command the war, and you have to pay attention to the training of the troops, and you also have to guide all kinds of production. Even in my spare time, I still have to write at my desk. This, this—"

"Say yes, no one is polite." Yang Tianfeng handed over the drawings and said, "With the new technology of manufacturing chrome barrel steel, it is time for us to produce infantry guns." It is still the old principle, first make the sample, and then set up the production line after the test is successful. This, like rocket artillery, is also to be hoarded, and it may be used for actual combat even later. (To be continued.) )
