The T-62 is a Soviet main battle tank that was first introduced in 1961. As a further development of the T-55 series, the T-62 retained many similar design elements of its predecessor including low profile and thick turret armour.
In contrast with previous tanks, which were armed with rifled tank guns, the T-62 was the first production tank armed with a smoothbore tank gun that could fire APFSDS rounds at higher velocities (the U.S. prototype T95 medium tank was the first tank ever built with a smoothbore gun).
While the T-62 became the standard tank in the Soviet arsenal, it did not fully replace the T-55 in export markets due to its higher manufacturing costs and maintenance requirements compared to its predecessor.
Although it was followed by later models in successor states of the Soviet Union, the T-62 remained in reserve in the former USSR and in frontline use by other countries. Design features of the T-62 became standardized in subsequent Soviet and Russian mass-produced tanks.
