PS. Present today's update, by the way, pull a vote for the "starting point" 515 fan festival, everyone has 8 votes, and the vote will also give the starting point coin, kneel and beg everyone to support and appreciate!

However, the effective range of the heavy machine gun is only 1,500 meters at most, and in order to deal with farther targets, Li Hui also deliberately studied the sub-technology of "machine gun", and also designed a machine gun carriage for long-distance maneuvering.

This carriage is equipped with a Makqin 37mm machine gun, which is commonly known as the "Bang Bang Cannon", which has not been put into actual combat in the world (the Anglo-Boer War a few years later), and its maximum rate of fire is as high as 400 rounds per minute, and it has also been optimized by Li Hui, which has improved its accuracy, charge and firepower continuity.

When the charge of the cannonball was changed to white, the effective killing area was almost doubled, while the cost of the shell was reduced, making the weapon more useful.

If he was not worried that he would not have had time to train, Li Hui would definitely recommend it to the Beiyang Naval Division, and if the so-called "machine guns" on the warships with a single-barrel rate of fire of only 20 rounds per minute could be replaced by this, even if the number of "machine guns" equipped by the Japanese army far exceeded that of the Beiyang Naval Division, they would not want to take advantage of the deck washing

In contrast, the lethality of this weapon when used in the army field is more terrifying, although there are skirmish tactics in the world, but the spacing of soldiers in the offensive queue is still obviously small, as long as the initial calibration is completed when defending, at least one platoon can be reimbursed for a chain of bullets after that.

In an attack, although they are limited by the enemy's fortifications and their effectiveness is greatly reduced, they still have a chance to show their might if the enemy wants to escape or counterattack.

In addition, the weakness of its somewhat heavy weight after being converted to a machine gun carriage was compensated, making it more practical.

Because the age of mortar science and technology is relatively late, and he cannot afford to study it for the time being, and his own arsenal cannot be built in a short time, Li Hui can only be responsible for the task of killing and suppressing fire at a distance of 1,500-3,000 meters with this weapon, which was later mainly used for air defense.

However, this can only solve the problem of medium-range attacks, and for more distant targets, you can only rely on real artillery

In many later materials, "tube retreat" is often regarded as a synonym for "rapid-fire gun", but in fact, it can only be said that "rapid-fire cannon must be a tube retreat gun, but tube withdrawal gun may not be a rapid-fire gun." ", because there are many other factors that will affect the rate of fire of artillery. The reason why the army rapid-fire gun appeared 11 years later than the navy rapid-fire gun is also related to this.

According to the law of conservation of momentum, its recoil will be very large, and it doesn't matter if the tonnage of the warship is huge enough to digest, but when applied to the army field artillery, there will inevitably be problems.

Because the resistance that can be generated by the hoe is not enough to balance the excessive recoil, the army field guns with a caliber of more than 57mm will inevitably be displaced once they are fired, and the result is equivalent to changing back to the old-fashioned rack guns, how can the rate of fire be fast?

Although clever artillerymen came up with the idea of constructing inclined positions, using gravity to reset the artillery on its own after the shelling was completed, the process was not too time-consuming, especially in a real combat environment.

Therefore, the rate of fire of army field guns in the world is generally not worth mentioning, even the so-called "rapid-fire guns", it is difficult to hit the rate of fire of more than 1 minute 3 rounds in actual combat, and at this time, the maximum rate of fire of 75mm caliber naval guns and fortress guns can already reach more than 15 rounds per minute

In addition, it is worth mentioning that although the use of sloped positions can increase the rate of fire of field artillery, it also leads to a great reduction in its flexibility, because it takes a long time to select a suitable artillery position and build a good inclined gun position before it can be fully effective, and their role in mobile operations will inevitably be greatly reduced.

Not to mention the fact that they could not keep up with the nimble enemy, once the troops were attacked by the enemy during the march, the artillerymen could only watch and it was difficult to provide fire support, and by the time they had built the artillery positions, the battle was in a good place

If you want to solve this problem completely, you must find a long-travel anti-recoil principle, which was first proposed by the Germans in history, but did not attract the attention of the German government and domestic military giants, but the French Schneider company bought the patent with a unique vision and improved it, and soon successfully launched the world's earliest hydraulic gas brake system.

Historically, in 1897, the French artillery development team composed of General de Ville, Colonel de Boer and Captain Rimaio, on this basis, developed an epoch-making generation of classics in the history of world artillery development -- the French Schneider 1897 75mm field gun.

The maximum rate of fire of this gun can reach more than 15 rounds per minute, and if it is equipped with a skilled gun crew and is not afraid to shorten the barrel life, this gun can reach an eye-popping rate of fire of 30 rounds per minute in a short period of time, and the rate of fire of rifles of the same period is not so fast (most of them are only 10-20 rounds per minute, only the British Lee Enfield rifle can reach a rate of fire close to 30 rounds per minute). ）。

Therefore, it is only natural that this field gun completely conquered all the French artillery as soon as it entered service, and was affectionately called "Miss Seventy-Five" by them

When the Eight-Nation Coalition invaded China (there are also very few sources that say that it was put into use during the Anglo-Boer War, but I personally think it is misinformation.) For the first time, the "Miss Seventy-Five" was put into service in real combat, and its stormy firepower shocked the whole world.

Since then, countries have bought patents from France for imitation, and soon after the end of World War I, "Miss 75" and her children and grandchildren have monopolized the army barrel artillery market. This grand occasion even lasted into the 21st century, and the "Miss 75" is widely regarded as the originator of modern army field artillery

Once such an excellent artillery appears on the eastern battlefield, where even "pseudo-rapid-fire artillery" is difficult to see, it will inevitably make all the Western powers look sideways, and it is precisely because he is worried that it will attract the attention of the Western powers too soon, Li Hui did not produce it immediately after completing the research and completion of this key technology, and planned to produce it to equip the troops when he really pulled the flag and rebelled.

Anyway, having dozens of pieces of this kind of artillery is already terrifying enough, and the biochemical soldiers are born with full training, so they don't need to consume much ammunition in peacetime. On the other hand, Li Hui also plans to use this time to optimize the "Miss Seventy-Five", this artillery is indeed very good, but in his eyes, there is still room for further improvement

[It's about to be 515, I hope to continue to hit the 515 red envelope list, and the red envelope rain will be able to give back to readers and promotional works on May 15. A piece is also love, and it must be better! 】
