The T-54 and T-55 tanks are a series of Soviet main battle tanks introduced just as the Second World War ended. The first T-54 prototype was completed at Nizhni Tagli by the end of 1945. Initial production ram up settled for 1947 at Nizhni Tagli, and 1948 for Kharkov were halted and curtailed as many problems were uncovered; the T-34-85 still accounted for 88 percent of production through the 50's.
