T-55A is a modernization of the T-55 tank, which was designed on the basis of the T-54. The reason for the creation of the T-55 was that by the 50s of the XX century, nuclear weapons had become widespread and there was a need for a tank that could operate in the conditions of its use. The new tank was based on the T-54B, a modification of the T-54 with a D-10T2S gun and a weapon stabilizer, as well as a new night vision device.
