Introduced in 1963 as a replacement for the fully tracked BTR-50, the BTR-60 represents the first of a series of 8x8 wheeled APC that are still in production in the former Soviet Union. In terms of numbers produced, the BTR-60 was the most important vehicle in the Soviet Army and was issued to the Soviet naval Infantry. In addition, the BTR-60 has been supplied to most Warsaw Pact countries in addition to North Korea. The BTR-60 has also been manufactured in Czechoslovakia and Poland.
Initial BTR-60s were equipped with a single 12.7mm DShK machine gun and two PKT 7.62mm machineguns, all mounted forward of the personnel compartment. Later models used the standard Warsaw Pact APC weapons turret equipped with one KPV 14.5mm machine gun and one PKT 7.62mm machine gun. Power is supplied to all eight wheels by means of a unique twin engine/transmission arrangement. The BTR-60 uses two V-8 90hp gasoline engines and two separate transmissions; one supplies power to the 1st and 3rd axles and the other supplies power to the 2nd and 4th axles.
The BTR-60 is fully amphibious and does not require any preparation time. Steering, both on land and in the water, is provided by the forward two axles, which are also power assisted. Water propulsion is provided by a single rear mounted water jet.
Although the BTR-70 began to replace the BTR-60 in 1978, the BTR-60 has never been retired, and continues to serve in Russian reserve formations and numerous countries world-wide.
The BTR-60 an all-wheeled 8x8 fully amphibious armored personnel carrier. The boat shaped vehicle is divided up into three sections: crew compartment, personnel compartment, and engine compartment. In early versions the personnel compartment is open topped; in later versions the entire vehicle is fully enclosed. The BTR-60 may be readily distinguished from the later 70/80/90 series by the presence of a single ""automotive-type"" muffler exhaust located on either side of the hull rear.
The BTR-60 "P" and "PA" variants are equipped with a single 12.7mm DShK machine gun and two PKT 7.62mm machineguns. These MGs are mounted forward of the personnel compartment, and require the gunners to be exposed while firing. Because of the size of the gunner's position, only two of the three MGs can be manned at any given time. The ""PB"" model is equipped with a small, one man, turret, mounted over the second axle that contains one KPV 14.5mm machine gun and one PKT 7.62mm machine gun.
In all models, the personnel compartment can only be accessed from the roof of the carrier. There are three infantry mounting steps on each side of the vehicle, mounted between the road wheels, and three additional mounting rails located on the hull above the steps. There is a large personnel compartment access hatch located on each side of the hull.
