After settling in the new office, which is the technology research and development center, Jiang Chen immediately put into intense work. Now he is getting closer and closer to the defense exhibition, so his pressure is very great, although he has some advanced knowledge and technology or advanced vision, but the development of weapons and equipment has a certain cycle. Even if Jiang Chen can provide detailed drawings, it will have to be thoroughly understood by these technicians and production workers before they can be produced. Not to mention that Jiang Chen is just an ordinary person, and it is impossible for him to remember it so clearly, and it is impossible for him to know all kinds of data, so most of them still have to be developed and conquered by the technicians here.

Several experimental prototypes of the new assault rifle have been produced, but the overall situation is still somewhat unsatisfactory. After all, Jiang Chen asked them to develop a new assault rifle in later generations, and there are a lot of materials and technologies on it. And now Jiang Chen doesn't know where to get these materials, although he has the help of the military, it is still a drop in the bucket. After all, the industrial level of the entire country is here, and Jiang Chen has no choice. He can only choose the right material to replace the existing materials, and although Jiang Chen understands the technology, it must also be applied to the current level of processing and manufacturing. For example, Jiang Chen now wants to make a holographic sight, there is no way, although he knows the technology in this area, but he can't produce it, there is no way, the components can't work.

While Jiang Chen was busy developing a new rifle, good news came from the research team of the 120-mm rocket launcher project. Now the 120-mm rocket launcher and the two rockets to which it belongs have been developed and samples are being manufactured. And the most basic safety tests have been completed, and it is now time to carry out further live-fire performance tests.

After receiving this news, Jiang Chen quickly arranged the research and development work in his hand, and then went all out to start preparing for this live-fire performance test. This 120mm rocket launcher is not as simple as the past firearm shooting test, the firearm shooting is just those few targets, and there is no need to consider any special shooting targets. Oh yes, there was a live pig test conducted by Dongzi before. But this 120mm bazooka can't be tested with live pigs, and the rifle can still eat meat after shooting, and if this 120mm bazooka is tested with live pigs, it is estimated that it will not even be able to drink soup.

All of the 120mm bazookas were not paper targets, but targets made of steel or concrete. This time, in order to be able to test it more in actual combat, Jiang Chen got a Type 59 main battle tank that was broken down from the army and transported to the steel plant to be disassembled for steelmaking through his grandfather.

This Type 59 tank is a medium tank developed and imitated by China in the 50s with reference to the Soviet-style T-54A medium tank, and it is the first generation of main battle tanks in China. In 1959, it began to equip our army, and until the 80s, it was the main equipment of our army's armored forces. It has good armor protection and maneuverability, the armor of the head and side of the hull is thicker, using homogeneous steel armor, 100mm in the front, 80mm in the side, 45mm in the rear, 45 ° bevel angle in the front, and the thickest part of the front is 100X2 = 200mm thick (when the angle with the horizontal plane is 30 °). [2] The body is welded from rolled steel plates. The turret is cast, streamlined, and has good bullet resistance. This poses a huge challenge to the armor-piercing capabilities of the newly developed 120-mm bazooka.

This time Jiang Chen went to the steel factory not so in vain, he picked up the grass and beat the rabbit and directly transported some huge steel structures that were transported to the steel plant to be melted off, some were even as thick as 400 mm, Jiang Chen's purpose of transporting them with so much effort was very simple to see the maximum ability of serious armor-piercing bullets. Of course, Jiang Chen is not taking it for nothing, although it has a relationship, he still has to abide by the regulations, how many tons of steel are shipped out, then you have to bring back as much as you want, and you have to make up for it yourself. Jiang Chen thought that it shouldn't cost much, so he readily agreed.

Seeing these things being placed in the test ground, Jiang Chen sighed, it was really a cannon that sounded, and it was ten thousand taels of gold. Not counting the price of the rockets to be launched, it costs a lot of money to make these targets that are to be destroyed. Let's just say that this test site has also been expanded several times to ensure that shells do not fall outside. Some people will ask why it is not in the previous uninhabited river beach, in fact, it is like this, in the river beach is only a preliminary test in order to prevent accidents, it is put there, and now it is considered to be successfully developed, so there is no need to run so far, and the rocket will not turn and fly back. And there are more and more things to test in the future, so sooner or later you will have to use them, so it's better to use them now as soon as possible.

However, what Jiang Chen didn't expect was that many leaders and brother factories were coming, such as Deputy Director Lu of the Bureau of Science, Technology and Industry for National Defense, Director Liu Zhengqing and Director Liu of the General Rear Department, as well as the leaders of the Aviation Institute, Cheng Peng, the technical chief of the G13 factory, and so on, all of whom had to come to observe the test, so that this test became the significance of the report. But there was no way, Jiang Chen and the B17 leaders persuaded them many times, but they insisted that they had nothing to do, and the officials crushed people to death. It made the leaders of the factory nervous to death one by one, and then they all chased Jiang Chen's ass and asked if they could succeed, if they failed this time, the person would lose everything to the Pacific Ocean. Jiang Chen couldn't assure them, this was originally a test, and if it was a test, there would be failures, and he couldn't master it. The last one repeatedly asked Jiang Chen to minimize the risk and then sighed and left, now it depends on the will of heaven.

But they didn't know that they were doing it themselves, and they completely blamed Jiang Chen for being so swaggering, he was enclosing the test site again, and he was looking for a relationship to transport the scrapped 59 tanks, and it was difficult for others to know about such a big formation. What's more, there is also a military representative in the factory who is good at making small reports, and he reported the last firearms development. It is now estimated that the whole system is watching this test.

Finally the test began, Jiang Chen saw that so many people were a little stressed, and he had just discovered the reporter, so he wanted to drive them away under the guise of secrecy, but when he inquired that the person was from Xinghua Society, he had to swallow the verbal words.

When they were ready, Jiang Chen stepped forward and introduced to everyone with the bazooka and two kinds of rockets, "Chiefs, comrades, this is the 120 mm rocket launcher we developed and the two rockets it is equipped with, which is mainly composed of a launcher, a rocket, a firing machine, a sight and a detachable tripod. This cylinder is the rocket launcher we developed, and it is with it that we launch this ammunition. The weight of the entire empty barrel is 12 kg, it has a caliber of 120 mm and a length of 950 mm, and it can be fired alone by individual soldiers and shoulders, or it can be fired by a team with a tripod. ”

"This short is an ordinary explosive anti-personnel projectile, it weighs 8 kilograms, the muzzle velocity is 200 meters per second, filled with more than 120 steel balls, can effectively target the enemy's living forces and light armor and some fortifications, etc., the warhead killing radius is 25 meters, and the maximum range has been measured 1800 meters. ”

Jiang Chen drowned a mouthful of spit and continued: "This kind of sharp and slender armor-piercing bullet, the bullet weighs 7 kilograms, uses a tandem warhead, filled with a precision pressure column, and the muzzle velocity is 220 meters per second, and the endurance engine designed by our Joint Aerospace Research Institute makes the missile shoot in a crosswind of less than 5 meters per second, with an effective range of 400 meters launched on the shoulder and 600 meters when launched on a tripod. He mainly used armor-piercing shells against tanks, armored vehicles, pillbox fortifications. ”

"Now let's show you how to launch, and you can see in the distance. Jiang Chen thought that Dongzi and Er Mazi, who were preparing in the distance, gestured to Zhang Wanglong. This launch mission was won by them on their own initiative, and no one persuaded them. Even Jiang Chen's persuasion was useless, Dongzi shed tears in front of Jiang Chen every day. And Er Mazi Zhang Wanglong's insistence made Jiang Chen feel a little moved by him, and finally gave him this opportunity, hoping that he would perform well.

I saw Dongzi and Er Mazi carrying a bazooka, and one running to a place with a cartridge loaded with two rockets and squatting, but Dongzi carried the bazooka and shouted: "200 meters ahead, a concrete fortification was found, and an explosive anti-personnel bomb was loaded." ”

"Yes! Zhang Wanglong put the bag down, pulled out a rocket from it, then hugged it and stuffed it from the back of the bazooka, locked it tightly with the locking device, and then ran back to the original place and crouched down and shouted: "Loaded." ”

"Launch!" Dongzi pulled the plane, and in an instant, the rockets in the bazooka erupted with a strong wake and broke out of the barrel, hitting the concrete fortification that was aimed at it and then exploded violently, and after a burst of stones mixed with dust, there was only the base of the two-meter-thick concrete fortification that was still there just now.

"Okay!" the crowd stood up and applauded one by one.

After waiting for a while, Jiang Chen signaled to continue, and this time Dongzi turned his target to the Type 59 tank on the other side, and he shouted loudly: "A 59 tank was found 200 meters ahead, and an armor-piercing bullet was loaded." ”

"Yes! Zhang Wanglong pulled out a rocket from it, then grabbed it, stuffed it from the back of the bazooka, locked it with the locking device, and then ran back to the original place, crouched down and shouted: "Reloaded." ”

"Fire!" In an instant, a large hole was torn open in the armor of the 59th tank over there near the frontal battery, and then it seemed to ignite something inside, and now black smoke is coming out of the big hole.

At this time, the audience was silent for an instant, and after waiting for a while, everyone cheered excitedly, this time louder than just now, and lasted several times, each time higher and higher. Everyone present was an expert, and they knew how difficult it was to hit the armor of this 59 tank near the frontal battery (at that time), but now this little thing is as easy as chopsticks poking paper, which is a great shock to them.

、、、、、、

Then after waiting for the end of a series of test projects, when Jiang Chen handed the test report to the leaders, the leaders read it, discussed it in a whisper after being shocked for a while, and then pulled Jiang Chen aside and whispered: "Xiao Jiang, you have played big this time, your bazooka country will not let you sell it." ”

Jiang Chen panicked and shouted, "Why?

These leaders looked at the people around them, just smiled wryly and didn't say anything.

Jiang Chen looked around for a moment before he suddenly reacted, then patted his forehead and said with a wry smile: "This time it's really a big trouble." ”
