Introduction

The PT-76 is an amphibious light tank of Russian origin. Development began shortly after World War 2 and it equipped most Soviet forces during the Cold War. Nowadays small numbers remain in use, mostly with third world nations.

Layout

The PT-76 is a tracked amphibious light tank. The hull is very large in order to create buoyancy and stability while afloat. The driver is seated in the front of the hull. The turret is fitted in the middle and houses the commander and gunner. The engine and drivetrain are mounted in the rear. Two hydrojets provide propulsion in the water.

Firepower

The main armament is a 76.2mm D-56T cannon, which was non-stabilized in early versions. A total of 40 rounds are carried. The rate of fire is 6 to 8 rounds per minute. As a coaxial weapon a 7.62mm SGMT or PKT machine gun is fitted. Additionally some PT-76 are fitted with a 12.7mm DShK heavy machine gun on the turret roof.

Protection

To keep the weight down for the amphibious capability the armor is quite thin. The steel armor protects against small arms fire and shell splinters. Many PT-76 were not fitted with a NBC system, fire extinguishing system or the ability to lay a smoke screen.

Mobility

The PT-76 has a good cross country performance and is fully amphibious. The road speed is somewhat limited. A 240hp diesel engine provides propulsion.

Users

The PT-76 was used by most Soviet and Eastern European forces during the Cold War. It was also widely exported to nations with close ties to the USSR. Nowadays small numbers remain in use with Russian naval infantry and many others with third world nations.

Variants

PT-76

The original PT-76 is armed with a non-stabilized D-56T 76.2mm cannon and 7.62mm SGMT coaxial machine gun. The improved PT-76B is armed with an improved and stabilized D-56TS cannon. Additionally it is fitted with a PKT coaxial machine gun, NBC system and an improved engine. The PT-76A designation is used for PT-76 and PT-76B that are fitted with a 12.7mm DShK heavy machine gun on the turret roof.
