Description
The T-54 and T-55 are a series of Soviet medium tanks developed to succeed the T-34 and T-44 designs. The first T-54 prototype was completed in Nizhny Tagil in 1945, and the vehicle officially entered service in 1946. Serial production began in 1947 at Nizhny Tagil and 1948 in Kharkiv. The T-55 variant was developed in the mid-1950s following trials with nuclear weapons, which led to the creation of the PAZ nuclear, biological, and chemical (NBC) protection system. This model entered service with the Red Army in 1958. In addition to the Soviet Union, the tanks were manufactured in Poland and Czechoslovakia, while China produced a version designated as the Type 59.
The tank's layout consists of a fighting compartment in the front, an engine compartment in the rear, and a dome-shaped turret centered on the hull. The primary armament is a 100mm rifled gun. Secondary armament typically includes 7.62mm coaxial and bow-mounted machine guns, with some variants featuring a 12.7mm anti-aircraft machine gun. The T-54A introduced the STP-1 vertical stabilizer, while later models like the T-54B and T-55 utilized the STP-2 two-plane stabilization system. Protection is provided by cast turret armor and steel hull plates. Modernizations introduced over the decades added laser rangefinders, infrared searchlights, and explosive reactive armor. The suspension uses torsion bars with five road wheels per side, characterized by a visible gap between the first and second wheels.
The T-54/55 series was produced in large numbers and remains in service with approximately 50 armies worldwide. The series first saw combat during the 1956 Hungarian Revolution. In the Middle East, the tanks were used by Arab forces in the Six-Day War and the Yom Kippur War; Israel subsequently operated captured and modified versions designated as the Tiran. During the Vietnam War, the People's Army of Vietnam utilized T-54s and Type 59s against ARVN and US forces. Other combat deployments occurred during the Indo-Pakistani War of 1971, the Soviet-Afghan War, the Iran-Iraq War, and the Angolan Civil War. In the Yugoslav Wars, the T-55 served as a primary armored asset for several factions. More recently, the tanks have been deployed in the Syrian Civil War and the Russian invasion of Ukraine. In current operations, these vehicles are frequently utilized as assault guns to provide fire support for infantry at extended ranges.
