T-54/T-55
The T-54 and T-55 tanks are a series of Soviet medium tanks introduced in the years following the Second World War. The first T-54 prototype was completed at Nizhny Tagil by the end of 1945. From the late 1950s, the T-54 eventually became the main tank for armoured units of the Soviet Army, armies of the Warsaw Pact countries, and many others. T-54s and T-55s have been involved in many of the world's armed conflicts since their introduction in the second half of the 20th century.
The T-54/55 series is the most-produced tank in history. Estimated production numbers for the series range from 96,500 to 100,000. They were replaced by the T-62, T-64, T-72, T-80 and T-90 tanks in Soviet and Russian armies, but are still used by up to 50 other armies worldwide, some having received sophisticated retrofitting. The Chinese version of the T-54A is the Type 59.
During the Cold War, Soviet tanks never directly faced their NATO adversaries in European combat. However, the T-54/55's first appearance in the West around the period of the 1950s (then the beginning of the Cold War) spurred the United Kingdom to develop a new tank gun, the Royal Ordnance L7, and the United States to create the M60 tank.
The Soviet T-34 medium tank of the 1940s was well regarded and development never stopped throughout the Second World War. It continued to perform well; however, the designers could not incorporate the latest technologies or major developments as vital tank production could not be interrupted during wartime.
In 1943, the Morozov Design Bureau resurrected the pre-war T-34M development project and created the T-44 tank. Thanks to a space-efficient torsion-bar suspension, a novel transverse engine mount, and the removal of the hull machine-gunner's crew position, the T-44 had a cross-country performance at least as good as the T-34, but with substantially superior armour and a much more powerful 85 mm gun.
By the time the T-44 was ready for production, the T-34 had also been modified to fit the same gun. Although the T-44 was superior in most other ways, by this time, T-34 production was in full swing and the massive numbers of T-34s being built offset any advantage to smaller numbers of a superior design. The T-44 was produced in only small numbers, with around 200 completed in 1945. Instead, the designers continued to use the design as the basis for further improved guns, experimenting with a 122 mm design, but later deciding a 100 mm gun was a better alternative.
Efforts to fit the 100 mm gun to the T-44 demonstrated that small changes to the design would greatly improve the combination. The main issue was a larger turret ring, which suggested slightly enlarging the hull. A prototype of the new design, about 40 centimetres (16 in) longer and only 10 cm wider, was completed in 1945. This model looked almost identical to the original T-44, albeit with a larger gun.
Testing revealed several drawbacks that needed correcting and many alterations that had to be made to the vehicle's design. It was decided to begin serial production of the new vehicle and the vehicle officially entered service in April 1946. It would go into production in Nizhny Tagil in 1947 and Kharkiv in 1948.
