There was still a day before the convening of the crossing conference, and Shen Daxing found Zheng Jiang and Zhang Guodong again.

"Two chairmen." Shen Daxing rubbed his hands and was a little excited, "If the two of you are free, come with me to my place, there is something good I want to invite you to pass by." ”

Zheng Jiang raised his head and smiled: "Daxing, when did you play with antiques, you have to let me pass by, you got Yuan Qinghua or Yongle porcelain." ”

"I don't have that hobby." Shen Daxing replied, "You two will find out if you two go and see." ”

Zhang Guodong stood up and asked, "Then go and see your good things, but what did you come up with, I think you're very excited." ”

"Actually, it's nothing, we got a grenadier."

"What did you say, you made a grenadier?" Zheng Jiang didn't react, but Zhang Guodong, who was born in the military, was taken aback by Shen Daxing's words.

The grenadier was once widely used by the Japanese army on a large scale on the anti-Japanese battlefield in World War II, and each Japanese infantry squad would be equipped with one or two grenadier teams.

The grenadier of the Japanese army was essentially a light mortar, its main features were a large angle of fire, a curved trajectory and a short range. It is mainly used to kill and injure the enemy hiding behind fortifications and concealments or to kill and injure the enemy's living force at a long distance, its killing effect is good, it is easy to operate, and can be accompanied by a single soldier to move with the first-line infantry to support the first-line infantry. It is highly concealed due to its individual portability and the ability to launch behind obstacles. The grenadiers are carried by special ammunition bags, one of which can carry eight grenades, and a two-person grenadier group of 16.

The Japanese grenadiers were divided into two types, the Taisho 10 grenadier caliber was 50 mm, the weight was very light only 2.6 kg, and the range was 175 meters. It was designed primarily for the Japanese military to be able to bridge the gap in fire between medium mortars and individual grenades, while at the same time being able to significantly increase the firepower of infantry detachments (the equivalent of squads in the Chinese army).

However, the Taisho 10-style itself was not very good, its range was too short (less than 200 meters), which made it impossible for soldiers to use it at a relatively safe distance, and its accuracy was not good, which made it quickly replaced by the later 89-type grenadier canister.

The 89 type grenadier is an improved version of the Taisho decade, the caliber is also 50 mm, the total length of the gun is 413 mm, the length of the barrel is 260 mm, the weight of the whole gun is 2.7 kg, the weight of the barrel is 1.6 kg, the length of the barrel foot is 170 mm, the weight of the barrel plate is 1.1 kg, the height of the foot plate is 60 mm, the width of the foot plate is 67 mm, the maximum firing range is 700 meters, and the effective firing range is 500 meters.

"Chairman Zhang, don't get excited." Shen Daxing said, "The grenadiers we made will never be the same as those in World War II, and we haven't made fire caps and primers until now." Actually, we just made a small mortar. ”

Zhang Guodong smiled: "Okay, you scared me, I thought you had achieved leaps and bounds." ”

Shen Daxing explained: "But Chairman Zhang, don't underestimate this thing, we have tested it, although the power is not as good as our six-pounder gun, but it can hit the parabola, it still has a certain effect, the key is that there are few people and the cost is low." ”

Zheng Jiang also stood up: "Daxing, it's useless to say anything else, take me and Chairman Zhang to see your mortar." ”

The two high-ranking officials saw the grenadier in Shen Daxing's mouth at the Military Research Institute. This small mortar has a caliber of 8 cm, a gun length of 90 cm, an adjustable stand, a total weight of 11 kg, and a firing elevation angle of up to 45 degrees.

Zhang Guodong looked around the grenadier: "How far can this thing hit, how many people operate it, and what kind of shells are used?" ”

Shen Daxing pointed to the sample on the ground and replied: "After testing, the range is not too far, about 180 meters to 200 meters. However, this thing is lightweight, and it does not need mules and horses, it can be operated by three to four people, and if you are proficient, you can shoot 2 to 3 cannons a minute. ”

"As for the shells." Shen Daxing picked up a sample of an artillery shell from the side, "We are going to use all flowering shells, and the killing radius can reach 3 meters." ”

Zheng Jiang didn't understand these things very well, so he interjected and asked: "So this thing is useless, the range is not as far as a rifled gun, and the killing radius is not very large, what can you use it to fight." ”

"Chairman Zheng, you don't understand this." Shen Daxing explained, "Your military people have approached me several times. Now Tao Min and they are also very good at using trenches and shield vehicles, and it is difficult to deal with them without mortars, so we did this, you don't know, it took a lot of effort. ”

"Daxing, you don't have to complain, report the parameters to the Military Commission, and the Military Commission will come up with a resolution after studying it. At present, it is necessary to step up the production of rifled guns and new rifles, and the spring offensive is about to begin. Zhang Guodong didn't have much confidence in this kind of mortar in his heart, because both in terms of range and power were too small. The main role of mortars is to clear enemy fire points, especially machine-gun positions, but the question is which machine gun is now. If it is used against artillery or cavalry charges, it will definitely not work, and the range of 180 meters will not even catch up with a three-pounder gun. But Zhang Guodong was also unwilling to dampen Shen Daxing's enthusiasm, so he still praised a few words.

"I know that I won't delay going to Vietnam." After Shen Daxing finished speaking, he stopped the two people who were leaving, "Two, there is still something to report to the two of you, Ye Sunquan gave me a report, I want to resign and quit." ”

"Lao Ye is going to resign? Why, didn't he do a good job, why did he suddenly stop doing it. Zheng Jiang stopped and asked.

"Actually, he had this idea for a long time." Shen Daxing said, "Now the Ye family is also a rich family in the entire Qiongzhou Mansion, and the three sons are all promising, Lao Ye wants to go home to hug his grandson, and his thoughts are all on his grandson now." ”

"And how did you reply?" Zhang Guodong asked.

"I just refused." Shen Daxing said with a smile, "Lao Ye also signed a confidentiality ordinance, and even if he goes out of the military research institute, he can't engage in other work." But I promised him that I wouldn't give him too much work in the future, and that he would just come and see him every day when he was fine, even if he was a consultant. In fact, in recent years, Lao Ye has not made much effort, our current arms research and development is becoming more and more modern, and he can't understand many things at all. We are mainly recruiting students who have graduated from the academy and Wanzhou Academy, and Lao Ye probably understands that he is useless, so he made this application. ”

"Then come according to your arrangement." Zhang Guodong said again, "But people like Ye Sunquan must be taken care of, don't let someone in your family feel that the tea is cold." ”
