Seeing Zhang Yunfei standing there, motionless, a little dazed, the two girls immediately stopped splashing water, walked in front of Zhang Yunfei, and asked with concern, "Yunfei, what's wrong?" ”

"It's okay, don't worry about me." Zhang Yunfei, who came back to his senses, immediately smiled.

Seeing that Zhang Yunfei was really fine, the two girls were a little relieved, and they happily talked and laughed with Zhang Yunfei, but Zhang Yunfei suddenly thought of rocket artillery just now, and his heart was already boiling, thinking about returning to Datong as soon as possible, and sorting out the knowledge about rocket artillery he knew in his mind.

So, the three of them played for more than an hour, and it was more than four o'clock in the afternoon, so Zhang Yunfei said: "Yuxin, Xiaoying, get in the car, let's go back." ”

Zhang Yunfei, who returned to Datong, sorted out the knowledge in his mind, and specially found a notebook, wrote down some of the knowledge he thought of, and drew a few sketches, and was busy until late at night.

Lin Yuxin and Jiang Xiaoying, seeing that Zhang Yunfei was concentrating, kept writing and painting in the study, and did not come to disturb Zhang Yunfei, at more than eleven o'clock in the evening, the two saw that Zhang Yunfei had not stopped, and thoughtfully served Zhang Yunfei a supper.

was busy until almost one o'clock in the evening, Zhang Yunfei breathed a long sigh of relief, he already had a general plan in his heart, Zhang Yunfei decided to produce rocket artillery as soon as possible, as a secret weapon, and then give the little devil a surprise blow.

After finishing everything, Zhang Yunfei, who was lying on the bed, was still thinking about rocket artillery.

Rocket artillery is a multi-launch device that launches rockets, and the rockets it launches fly by the thrust of its own engine. Rocket artillery can launch a large number of rockets in a very short period of time and carry out surprise attacks on long-distance targets in a large area, so as to annihilate and suppress the living forces and technical weapons, and give the enemy a great spiritual shock.

At present, a large number of trucks have been produced in the base area, and Zhang Yunfei is preparing to produce vehicle-mounted multiple rocket launchers, preferably 40 rocket launchers, but whether it is feasible or not will have to wait for tomorrow to convene relevant experts for exchanges and demonstrations.

As for whether or not rocket artillery can be produced, Zhang Yunfei is not worried, the Soviet Union should have produced rocket artillery several years ago, and according to the current technical strength of the base areas, coupled with his own "guidance," Zhang Yunfei believes that it can be produced.

Since rockets fly on the thrust of their own engines, rocket artillery does not need bulky barrels and bolts that can withstand huge chamber pressures, and there are no recoil devices. So as long as the problem of the rocket engine can be solved, the rocket artillery that Zhang Yunfei wants can be produced.

Rocket artillery can launch multiple combined shots and launch rockets with a large diameter, its launch speed is fast, the firepower is fierce, and the surprise attack is good, but the projectile spread is large, so it is mostly used to carry out area firing strikes on targets.

If on the battlefield, dozens of rocket launchers suddenly appear, each carrying 30 or 40 rocket launchers, dozens of launchers quickly enter the battlefield, and all the launchers fire all the rockets within a few minutes, and then quickly exit the battlefield.

Thousands of rockets, fired in such a short period of time, the little devil will definitely not be able to react, not only can quickly destroy the little devil in a large area, but also shock the little devil to a great extent.

The more he thought about it, the more excited Zhang Yunfei became, lying on the bed for a long time before falling asleep, and early the next morning, Zhang Yunfei walked to the headquarters with great interest.

Zhang Yunfei took out the book about rocket artillery knowledge that he had recorded last night, looked at it seriously on the table, and took out a pen to continuously supplement and improve it while reading.

Comrade Zuo Qingquan, chief of the General Staff, came relatively early, and as soon as he entered the office, he saw Zhang Yunfei concentrating on writing and drawing, and immediately came over with great interest, looked at it with great interest, and said happily: "Commander-in-chief, what is this rocket artillery?" ”

Zhang Yunfei had already discovered that Comrade Zuo Qingquan, chief of the general staff, had entered the office, and now when Comrade Zuo Qingquan asked, Zhang Yunfei also stopped, smiled and joked: "Chief of Staff Zuo, I dreamed last night that Lu Ban, the god of our craftsmen, taught me a weapon of war, the manufacturing method of rocket artillery, and as soon as I woke up this morning, I couldn't wait to record what I dreamed about last night." ”

After hearing this, Comrade Zuo Qingquan also laughed, knowing that Zhang Yunfei was joking, but he was still very interested: "Commander-in-chief, tell me what kind of weapon this rocket launcher is?" ”

As soon as Comrade Zuo Qingquan's words fell, the voice of Deng Wenping, director of the General Political Department, sounded outside the door, "Commander-in-chief, what new weapons are you talking about, which has opened my eyes to old Deng." ”

Zhang Yunfei smiled faintly, and then talked eloquently to Zuo Qingquan and Deng Wenping, "The new weapon I envisioned is called rocket artillery, which is mainly driven by a rocket engine to fly forward, and I expect that the range can reach more than ten kilometers, and the caliber of the rocket can be designed to range from 100 mm to 300 mm, and the power will not be less than that of heavy artillery."

The characteristic of rocket artillery is that it can fire hundreds or thousands of rocket salvos, which can be fired in just one or two minutes, and can cover a large area and give the enemy a devastating blow,......"

Zhang Yunfei talked eloquently, and patiently explained in detail to everyone, everyone's eyes lit up when they listened, and even Liu Dazhu and Fang Zheng, who came in later, sat silently next to them, listening to Zhang Yunfei's explanation excitedly, everyone thought in their hearts, if there is such a powerful weapon, then the little devil should be unlucky.

After Zhang Yunfei finished speaking, everyone was still immersed in excitement and joy, and it took a long time to come back to their senses, and Comrade Zuo Qingquan, chief of the General Staff with great strategic vision, said happily: "Commander-in-chief, this weapon you said is so good, how about we immediately arrange for experts from the Weapons Research Institute to design it and seize the time to produce it?" ”

Several people next to him also looked at Zhang Yunfei with expectant eyes, Zhang Yunfei smiled slightly, and immediately said: "Then notify the relevant experts immediately, and in an hour, a meeting will be held in the conference room of the headquarters." ”

Nearly 100 experts in weapons, machinery, vehicles, and other fields gathered together in the large conference room of the 36 th Group Army, and everyone was very happy to hear that it was the chief who was going to give everyone the task of developing new weapons.

Not long after everyone arrived, Zhang Yunfei and several other high-level officials of the 36th Group, supported by several staff officers of the headquarters, strode into the conference room.

Zhang Yunfei waited for the rostrum of the conference room to sit down, the applause gradually stopped, Zhang Yunfei looked around at everyone, and then said majestically: "Everyone stand up, everyone review the confidentiality regulations." ”

Under the guidance of an operational staff officer, everyone read aloud the secrecy regulations one by one, and it took them several minutes to read them out.

The secrecy regulations were drawn up by Zhang Yunfei at the behest of the command, and every secrecy officer must abide by the secrecy system for scientific research and the middle and high levels of the military; if there is any violation, he will be punished in accordance with the regulations, and if he commits the crime of leaking secrets, he will be shot on the spot if he commits a serious crime.

Today, because the development of rocket artillery is a matter of great importance, it is necessary to do a good job of keeping it secret, and we must not let the little devils know about it, and Zhang Yunfei does not want friendly forces to know that after the successful development of rocket artillery, it will be used as a killer weapon of the 36 th Group Army.

After everyone reviewed the confidentiality regulations, Zhang Yunfei motioned for everyone to sit down, and said solemnly: "Everyone read the confidentiality regulations just now, and I hope everyone will keep in mind that the content of today's meeting will not be leaked."

The main purpose of calling you to a meeting at the headquarters of our 36 th Group Army today is to develop a new type of weapon, which is called rocket artillery, and after it is successfully developed, it will be a great weapon of war, and all of you here will make great contributions,......

Next, Zhang Yunfei gave a detailed introduction to the use, basic structure, and principle of rocket artillery, and sent a few sketches that he had drawn temporarily to everyone for circulation.

After Zhang Yunfei finished speaking, he asked loudly: "Do you have the confidence to develop the rocket artillery that the army urgently needs?" ”

"Yes! Yes! Yes! The nearly 100 experts below replied loudly.

Seeing that everyone was full of confidence, Zhang Yunfei nodded with satisfaction and said loudly: "Director Yu of the Weapons Research Institute came out and came up to receive the research and development task book. ”

The Weapons Research Institute is a newly established research institute that integrates resources six months ago and specializes in developing various weapons and equipment, and there are hundreds of experts and technicians of all kinds below, including many Jews and Europeans and Americans in addition to most of the Chinese.

With the development of the Datong base area, Zhang Yunfei, who knew very well that science and technology were the primary productive forces, perfected and refined the original Datong Academy of Sciences; in addition to the Academy of Sciences, which specialized in scientific research, several research institutes were also set up, in addition to the weapons and equipment research institute just now, there were also machinery and equipment research institutes, manufacturing technology research institutes, pharmaceutical research institutes, silicate research institutes, petroleum and rubber research institutes, and so on, and recently set up an agricultural research institute with two or three hundred people.

After such a long period of development, the industrial and scientific and technological systems have been basically perfected, all kinds of military enterprises have been basically completed, and all kinds of civilian factories have been completed and put into operation one after another.

The director of the Weapons Research Institute, who was named by Zhang Yunfei, walked quickly in front of Zhang Yunfei with a face full of pride, saluted a solemn military salute, and respectfully accepted the rocket artillery development task book with both hands.
