Luo Yue said: "If it is a general-purpose machine gun, then it can only be delegated to the combat units at the platoon level at most, and it is still impossible to improve the combat firepower of the units at the squad level." ”

Qiu Yahui said with a smile: "Forget about the combat units at the squad level, in this era, light machine guns are generally delegated to combat units at the company level, and there are very few units at the platoon level, so equipping combat units at the squad level with machine guns is already a matter after World War II." Moreover, the so-called light machine guns of this era weigh about 10 kilograms, which has almost caught up with the general-purpose machine gun, and a machine gun needs at least 4 people to serve, and the real squad light machine guns should be under 7 kilograms, like the Type 95 squad machine gun we used before, which is less than 5 kilograms, so it can be done by one person, and a squad can be equipped with two, so it is impossible for the light machine gun of this era to be delegated to the combat unit at the squad level. He turned his head and asked Tang Nengzhi again: "What is the approximate performance of the general-purpose machine gun developed now?"

Tang Nengzhi said: "This machine gun is still based on the Madsen machine gun, although it is now recognized that the MG34 machine gun made in Germany in World War II is the first type of general-purpose machine gun, but the Madsen machine gun began to use a tripod configuration very early, so the concept of light and heavy general-purpose machine gun has long been reflected in the Madsen machine gun, but the Madsen machine gun is fed by a magazine, and the continuous firepower is relatively poor, and it is usually used as a light machine gun." Moreover, the technical conditions of the Madsen machine gun are easier to achieve in this era, and the MG34 machine gun not only uses a large amount of precious metal, but also its heat sink, casing, and many parts are cut out of a single piece of metal. Not only the material utilization rate is low, but also the process is complex and the processing time is long, and more importantly, it cannot be reached at our current technology level. The total length of this type of machine gun we developed is about 1250 mm, in the state of heavy machine guns, the full weight will be controlled at about 20 kg, and the full weight of the light machine gun state is controlled within 16 kg, of which the weight of the pure gun does not exceed 12 kg, using two modes of lateral drum and chain feeding, but the rate of fire is only 400 rounds per minute, and the firing range is 1000 meters. ”

Luo Yue said: "That's enough, the rate of fire of 5 or 600 rounds per minute is just a glamorous data on paper, and when it comes to the battlefield, it is very good to reach 300 rounds per minute." There are also many ranges of 1000 meters, but in fact it is about the same at 5 or 600 meters. ”

Qiu Yahui also nodded, and said: "The weight is quite appropriate, much better than the Makqin machine gun, a machine gun is enough for 6 people, under extreme conditions, even two people can do it, it can be used as a battalion-level support weapon, you can set up a machine gun platoon or machine gun company, which is directly commanded by the battalion headquarters in peacetime, and delegated to a company or platoon-level combat unit in wartime." The Maxim machine gun, on the other hand, is better used as a regimental fire support weapon. ”

Luo Yue said: "It is possible to use the Makqin machine gun as a regimental fire support weapon, but the general-purpose machine gun must be delegated to at least the platoon-level combat unit, and each platoon must be equipped with at least one, and it is best to be able to achieve two in a platoon, so as to ensure the firepower of the grassroots combat unit." ”

Tang Nengzhi also smiled bitterly and said: "I'm afraid this requirement is a bit difficult, because there is no stamping technology in this era, and the structure of machine guns is much more complex than that of rifles. ”

At this time, he did not speak, but Zhu Yaping, who recorded the speeches and discussions of the officers, said: "Let's wait for this type of machine gun to be finalized, if it cannot be mass-produced, we can imitate the Japanese army in the old time and space, divide the division into two categories, division A and division, prepare different weapons, and ensure that there are several elite divisions." He asked Tang Nengzhi again: "When will the sample gun come out." ”

Tang Nengzhi said: "It is estimated that the sample gun will be able to be produced next month, and after another month or two of debugging, the trial product can be released." After a pause, he said: "In addition, we are still developing *, the progress is similar to the general-purpose machine gun, three months later, you can start the trial, about the guns, the current achievements of the arsenal are these, another series of products is artillery, first of all, introduce mortars, there are samples here, but you can't test fire here, if you want to test fire, you have to go to the production base." ”

Luo Yue was also very interested when he heard this, although the firepower of the machine gun was powerful, but as the support firepower of the platoon and company level, the mortar was actually more powerful than the machine gun, so he immediately said: "There are those samples." ”

Tang Nengzhi said while arranging for personnel to take out the samples of the mortars and support them: "We have now produced a total of 4 types of mortars, namely 45 mm grenadiers, 60 mm mortars, 82 mm mortars, 100 mm mortars, and now we are developing 120 mm mortars. ”

Luo Yue said: "Is there still a grenade Jane?"

Tang Nengzhi nodded, picked up the smallest mortar that had just been erected from the table, handed it to Luo Yue, and said, " In fact, the grenadier is a light mortar, but in the old time and space, only Japan is equipped with a large number of this weapon, after all, some high is not low, other countries are basically using real mortars, of course, that was in World War II, and now the power of the grenadier is considerable, so our type of grenadier is an imitation of the Japanese 89 grenadier canister, caliber 45 mm, full gun length 425 mm, barrel length 285 mm, barrel foot length 140 mm, full gun weight 2.88 kg, gun barrel weight 1.82 kg, barrel plate weight 1.06 kg, effective firing range of 400 meters, maximum firing range of 600 meters, shortest firing range of 100 meters。 It can be launched *, or it can be launched with a dedicated *, of which * weighs 0.6 kg. ”

Qiu Yahui said: "The weight of this grenadier is good, but the range is not too close, 400 meters is not as good as the range of a rifle." ”

Luo Yue said: "I think it's okay, although the range of rifles in this era is more than 500 meters, but the general rifle firefight distance is basically within 300-400 meters, if it is farther, it is difficult to ensure accuracy." Moreover, the weight of this type of grenadier Jane is lighter than that of a rifle, and the shell is not heavy, so it can be carried by a single soldier, and can be used as a fire support weapon for the squad combat unit. And a platoon will have six sets of grenadier canisters, coupled with two general-purpose machine guns, such firepower is considerable. ”

Qiu Yahui laughed and said, "Don't rush to conclusions, what about these types of mortars?"

Tang Zhineng introduced them one by one: "The 60-mm mortar has a total weight of 16.2 kilograms, the barrel weighs 6.5 kilograms, the shell weighs 1.45 kilograms, and the maximum firing range is 1,800 meters; the 82-millimeter mortar has a total weight of 36.6 kilograms and a gun body weight of 15. 2 kg, the shell weighs 3.62 kg, the maximum range is 3200 m, and the 100 mm mortar, the total weight is 82.3 kg, the barrel weighs 38.2 kg, the shell weighs 7.82 kg, the maximum range is 5400 m. ”

Luo Yue and Qiu Yahui listened, and they also nodded frequently, the performance of these types of mortars is slightly worse than the mortars of the same caliber in the old time and space, but it is also quite considerable in this era, compared to the field artillery of the same caliber, it is surprisingly light, even the heaviest 100 mm mortar, on the battlefield can be carried by manpower, and the infantry fights together.

Luo Yue said: "Except for 60mm mortars, other types of mortars cannot be carried out on long distances by carrying them alone. Therefore, 60 mm mortars can be used as company-level support firepower, in groups of 6 people, to ensure that each platoon has two mortars, plus grenadiers and general-purpose guns, such firepower is enough against one company in this era. ”

Qiu Yahui also nodded and said: "Yes, the 82mm mortar is used as a battalion-level support firepower, and the 100mm mortar is used as a regiment-level support firepower, as long as the logistics support can be in place, in this era against the army of the same unit, it is basically invincible, but I don't know if our production capacity can be guaranteed in wartime." ”

Tang Nengzhi smiled bitterly and said: "Then it depends on how big the scale of the war is, there is no problem in supplying one or two divisions, but if it is the scale of World War I, even if it is the scale of the Russo-Japanese War, it is basically impossible." ”

Zhu Yaping made a note in the notebook and said: "We won't discuss the issue of production capacity first, just look at those weapons." Is that all mortars are?"

Tang Nengzhi said: "We are making a 120 mm heavy mortar, but the weight of this type of mortar is expected to reach about 300 kilograms, the weight of the shells is about 25 kilograms, and the range can exceed 6,000 meters. ”

Qiu Yahui said: "That's worth it, 300 kg of 120 mm guns, go where to find proper divisional support artillery fire." ”

Zhu Yaping said: "Don't worry, let's see what artillery can be produced in the arsenal." ”

Tang Nengzhi said: "In terms of artillery, we have determined the progression of caliber, which are 50 mm caliber, 75 mm caliber, 105 mm caliber, 125 mm caliber, and 155 mm caliber. Of course, now we have only made the first three guns, but the last two have already made barrels and are making other parts. However, there are no finished products here, I can only briefly introduce the performance of various types of artillery, 50 mm caliber rapid-fire gun, is an imitation of the Haqikai rapid-fire gun, the performance data are roughly the same, the total weight is 245 kg, the tube length is 45 times the caliber, the rate of fire is 20 rounds / 1 minute, the firing range is 4500 meters, mainly used for ships, of course, it can also be equipped with the army; the 75 mm caliber field gun is an imitation of the French M1897 75 mm field gun, the total weight is 1260 kg, the tube length is 35 times the caliber, the rate of fire is 15 rounds / 1 minute, the firing range is 7500 meters, and the 105 mm caliber light * gun is divided into two models, one is a 35 times caliber short-barreled gun, with a total weight of 2150 kg, a rate of fire of 8 rounds per 1 minute, and a range of 9500 meters, and the other is a 40 times caliber long-barreled gun, with a total weight of 2780 kg, a rate of fire of 8 rounds / 1 minute, and a range of 11000 meters. ”

Qiu Yahui was a little puzzled and said: "Why is the 105 mm caliber light * gun divided into two types: long-barreled and short-barreled?"

Tang Nengzhi said: "Because more than 100 mm should be regarded as large-caliber artillery, the cost of short-barreled guns is low, mainly to equip the army, and the cost of long-barreled guns is higher, mainly to equip the navy; such a combination of high and low is also conducive to reducing the cost of production, of course, if the army needs it, you can also order long-barreled guns." In the future, the two types of guns, 125 mm caliber and 155 mm caliber, will also use two types of long and short barrels, and we will further develop a 45 times caliber extended version. ”
