Development of Type 92 Heavy Machine Gun

The modern heavy machine gun originally equipped by the Japanese army on a large scale was the Maxim machine gun. A * * * introduced 200 guns, some of which were equipped with fortress troops. In the Sino-Japanese War, it was not practical on the battlefield. Maxim's machine gun needed the highest technology at that time, which Japanese industry didn't have. 1896, Japan took a fancy to the newly developed air-breathing machine guns in France and bought four for testing. 1898, members of the artillery conference and engineers of Hutchison (also known as Hotchkiss) tested Hutchison machine guns in Japan. The test was not very smooth, because long-distance transportation led to propellant deterioration and frequent failures, but the Japanese were still very satisfied with the machine gun after finding out the reason. 190 1 year, the army purchased the production patent of hutcheson Mle 1897 machine gun and 50 prototype guns. 1902, Japan began mass production of this kind of machine gun, also called protective gun. During the Russo-Japanese War, hutcheson also produced some other kinds of Japanese machine guns Mle 1897.

The caliber of Mle 1897 machine gun used in France is 8mm, and hutcheson Company has specially developed an export model for the Japanese army, using a 30-year-old 6.5mm rifle.

During the Russo-Japanese War, the Japanese army improved the Bao cannon according to the actual combat experience, and became the 38 cannon, with a total output of nearly 1,000 guns.

1909, more than ten improvements were made to Nanren Jiro's 38 heavy machine gun. 19 14 heavy machine guns were designed and finalized in three years. 1933 stopped production and * * * produced about 3,000 guns.

In the 1930s, airplanes were used more and more widely. The reliability of the Sixth Five-Year Tracer Bomb manufactured in Japan is extremely poor. Without tracer bullets, the efficiency of heavy machine guns shooting planes is very low. Moreover, with the increasing number of rival cars and equipment, the Japanese army had to increase the caliber of heavy machine guns.

1932 Based on Type 3 machine gun, Type 92 heavy machine gun with 7.7 mm bullet was developed.

The caliber is 7.7mm, the total length is 1 155 mm, the gun body is 72 1 mm, the guard plate of 30 rounds weighs 55.3 kg (including tripod), the gun body weighs 27.6 kg, the firing rate is 450 rounds per minute, the initial velocity is 732m/s, and the effective range is 800 meters and 200 meters. Equipped with Type 92 or Type 96 optical sight.

The total output of Type 92 heavy machine guns is 45,000, which is produced by Hitachi and Tokyo Heavy Machinery Industry. The production price at that time was 2 175 yen.

1 type 92 machine gun composition 1 machine gun unit (1 sergeant, 1 soldier, 2 horses) and 1 ammunition unit (1sergeant, 65438 soldiers, 8 horses). 1 machine gun squad consists of 4 machine gun squads and 1 ammunition squad.

Four men in the machine gun detachment carry machine guns, and each of the four ammunition soldiers carries a 4A ammunition box, which contains 22kg of 540 rounds of ammunition, ***2 160 rounds of ammunition, and two unlucky two 20kg B props boxes and reserve barrels.

Prop boxes are mainly all kinds of lubricating oil, and bulletproof plates must be used for all kinds of lubricating oil. Take the three-year machine gun as an example. Six heavy machine gun squadrons need to be equipped with six cans of 650g fatty oil, synthetic grease, 10 cans of 700 mineral oil, etc. The prop box also needs tools, needles, tools disassembled from each other, barrel poles, wearing parts, etc.

Ammunition detachment transports 4 boxes of 750 B ammunition boxes weighing 30kg per horse, and all ammunition detachment transports 32 boxes of 24,000 bullets, with a total of 9,660 bullets per machine gun.
