For a time, the Heavy Tank was the pinnacle in armor design for many of the leading military powers. It saw its peak usage during World War 2 though development of such types continued into the late-1950s. Those managing to reach operational-level status by then were ultimately retired during the 1990s for good. The Heavy Tank was replaced in frontline service by the arrival of the Main Battle Tank (MBT).
