Description


Introduction

The Type 74 is a vehicle machine gun of Japanese origin. It was developed as a successor to the Browning M1919A4. The Type 74 was developed for use on the Type 74 main battle tanks and has been fitted to various subsequent Japanese combat vehicles.

Design

The Type 74 coaxial machine gun is a highly modified Type 62. Key differences are the plain and very thick barrel, spade grips and solenoid trigger. The pistol grip, bipod and wooden buttstock are not fitted. Even without the furniture the Type 74 is twice as heavy as the Type 62.

Firepower

The Type 74 is a belt fed machine gun chambered for 7.62x51mm NATO. It has a low and high rate of fire setting. The cyclic rate of fire is 700 or 1.000 rpm. The heavy barrel allows for a high volume of fire. Practical range is 1 km and area targets can be engaged out to 1.5 km.

Platforms

The Type 74 was introduced as coaxial machine gun on the Type 74 main battle tank. The Type 74 can be found on many armored vehicles of Japanese origin since then. It was also retrofitted to some vehicles already in service, such as the Type 73 tracked armored personnel carrier.
