Description


Introduction

The Type 62 is an early Cold War era general purpose machine gun of Japanese origin. It was developed as a domestic and more modern weapon to replace the US Browning M1919A4 in Japanese service. The Type 62 was developed by NTK and was known as NTK-62 at first.

Design

The design may have been inspired by the contemporary Belgian FN MAG, but it differs in various areas. The Type 62 is a belt-fed general purpose machine gun with a quick change barrel. It gas operated and uses a long stroke gas piston. Iron sights and a wooden buttstock are fitted. A highly modified coaxial machine gun variant exists and is known as the Type 74.

Firepower

The Type 62 fires the 7.62x51mm NATO rounds at a cyclic rate of fire of 550 to 650 rpm. The maximum effective range is quoted as 800 m prone, 1.2 km from a tripod and 1.5 km when pintle mounted. The Type 62 uses NATO standard full power rounds, whereas the Japanese Type 64 battle rifle uses reduced load rounds.

Users

The Type 62 general purpose machine gun is only used by Japan and has never been exported. In infantry platoons each Type 62 was supplemented and replaced by two of the lighter 5.56mm FN Minimi machine guns. The Type 62 remains in use on tripods and pintle mounts
