a Brief history of the machine gun Type 98 7.92 mm:


Japanese army air force on the chinese battlefield could get acquainted with the efficiency of the soviet machine guns ŠKAS. These weapons were equipped with aircraft that the USSR added to the Chinese. Japanese army air force around the year 1937 a widely used machine guns of the type 89 in the implementation of a moving (model 1), or for fixed installation (model 2). This machine gun, however, was already quite technologically outdated, and it was actually a license-produced british machine-gun the Vickers Class E, which used a hub 7,7x58 SR. This weapon was in the Uk produced already during the first world war. Japanese machine guns for soviet ŠKASy hopelessly lagged behind, for example, the rate of fire was for the type 89 up to 50% lower. The technical department of the Dai-Nippon Teikoku Rikugun Kōkū Hombu (Imperial army air force) responded relatively quickly and quickly announced specifications with the technical requirements for a new weapon. This was required in the moving implementation, i.e., as a weapon of defense.

Japanese designers embarked into projects, but most failed to leave the machine gun type 89 and only offered to its more powerful variants, mostly based in his vícehlavňovém embodiment, therefore, the juxtaposition of the existing machine gun. An interesting proposal was from the designer Kijiro Nambu marked 6, but that definitely couldn't be completed and put into production in the foreseeable future. Army air force considered also the possibility to produce a copy of the machine gun ŠKAS that his technicians detail, for several such weapons the Japanese captured. This machine gun was eventually found to be too complex and demanding on maintenance. In the end, therefore, left with only one option - to purchase such a machine gun along with the rights for license production. At that time, however, was japanese aggression in China subject to the condemnation of many governments and the renegotiation of a similar trade was becoming increasingly less realistic option. Finally had a real opportunity to purchase a license in Italy and in Germany, the Japanese have left to submit different bids, and after their examination has been approached by the company Rheinmetall-Borsigwhose machine guns the MG 15 and the MG 17 for its simplicity and the performance of the Japanese most suit.

Already at the beginning of the year 1938 laid down the conditions for licensing the production of moving machine gun the MG 15 in the japanese army arsenal in Nagoya (名古屋陸軍工廠 - Nagoya Army Arsenal). In the agreed conditions, the company Rheinmetall-Borsig has set a condition that the Japanese will not be a machine gun to further self develop. The production was launched very quickly, the Germans have supplied drawings, sample pieces and a lot of parts for production immediately after the signing of the agreement. Army arsenal in Nagoya was actually five large plan, the dislocated and in the surrounding cities (Atsuta, Chikusa, Takagi, and Toriimatsu). It was originally for this machine gun reserved for the designation of the Te 5, but it is used. The germans quite a long time after the start of production supplied to Japan a considerable amount of parts for this machine gun. It was mainly double-sided drum mags, the springs of the shutter, some of the moldings and bakelite part of the handle.

Rikugun Kōkū Hombu planned rapid and extensive modernization of the machine-gun armament of the japanese planes, but this modernization was never fully completed. Many of the japanese aircraft continued to vyzbrojováno older machine guns type 89 model 1, the reason was obviously a logistical trouble. Rikugun Kōkū Hombu introduced into the armament of the fixed machine guns the MG 17, (the Japanese reportedly had problems with the production of the return springs) and so it was necessary to secure for each a military airport (and even on the most remote islands) the supply of ammunition of a caliber of 7.7 for fixed machine guns and machine guns of the variable calibre of 7.92 mm. An interesting and very rare, it was the fact that this weapon was also used air force maritime (海軍航空本部 Kaigun Kōkū Hombu), the naval gun was designated as Type 1 and was only minimally different from the army version, the development has been in both arms the joint and the hub are identical. This was exceptional, because in the vast majority of cases were all the guns and bullets are developed completely separately and completely independently.

Also in the marine corps, this weapon has not spread to a different caliber fixed machine guns.
