The Sumitomo NTK-62[6] (62式7.62mm機関銃, Rokuni-shiki Nana-ten-rokuni-miri Kikanjū) is the standard issue general-purpose machine gun of the Japan Self-Defense Forces. It's also known as the Type 62 GPMG.[7]
When first issued, it fulfilled both light and medium machine gun support throughout the JGSDF. Though the Sumitomo Heavy Industries' M249 firing the smaller 5.56×45mm NATO cartridge has largely replaced it in the light machine gun role at the squad level in the JGSDF,[8][9] the Type 62 still plays the support role at platoon and company level for the infantry as a medium machine gun firing the more powerful 7.62×51mm NATO cartridge. It also continues to be used as a co-axial weapon in various armored vehicles, including tanks and APCs.
Like all modern Japanese-made firearms, it was never exported.[3]
After years of using the Browning M1919A4 as its standard GPMG during the early days of founding the Japan Self-Defense Forces, NTK-62 GPMG was designed at Nittoku Metal Industry (NTK) in order to market it as the M1919's successor.[10] The GPMG was made to meet the requirements of the Japanese Defense Agency.[1]
The designation "62" was present due to the fact that first batches of the NTK-62 were made in 1962 after development started in 1954.[2] It was specifically adopted on February 15, 1962, effectively replacing the M1919 Browning machine gun in JGSDF service.[1]
In 2013, SHI was involved in a scandal where NTK-62 test data was falsified on purpose for 5,350 machine guns produced from 1974.[11]
The Sumitomo NTK-62 is a gas operated machine gun chambered in the 7.62×51mm NATO cartridge, belt fed with the use of M13 disintegrating links.[3] Pressed metal was used in parts of the machine gun during manufacturing in order to reduce overall weight.[10] While normal 7.62 NATO ammo is used, a version with reduced powder charge is also used.[10]
It has an unusual feed tray as the pivoting lever is above the bolt in the receiver, rather than in the feed tray cover found on most machine guns.[citation needed]
The design was done based on physique of the Japanese person who would be expected to handle the machine gun.[12]
The Type 74 (74式車載7.62mm機関銃, Nanayon-shiki Shasai Nana-ten-rokuni-miri Kikanjū) is a fixed mount variant for AFV use, including the Type 74, Type 90 and Type 10 MBTs, Mitsubishi Type 89 IFV and the Komatsu Type 87 Reconnaissance Vehicle.[13]
It weighs 20.4 kg (45.0 lb), unlike the Type 62 which weighs 10.15 kg (22.4 lb).[14]
