The T-80U is a Soviet medium tank. It was introduced in Update 1.87 "Locked On".

The T-80U is an all-round upgrade to the T-80B and one of the most advanced MBTs fielded by the Soviet Union. With a new turret and Kontakt-5 ERA, it visually distances itself from its T-64 ancestors and boasts hefty protection against both chemical and kinetic rounds. The engine power has been improved by about 14% and the resulting power-to-weight ratio matches contemporary NATO tanks like the Leopard 2A4 and IPM1. The firepower has also kept up with the times because of its top 3BM46 APFSDS and 9M119 ATGM. The combination of good armour, low profile, high mobility, and a punchy gun make the T-80U a versatile tank that doesn't leave very much to be desired. The post-penetration survivability and reverse speed could still be better, but Soviet tankers will be used to these flaws by now and the latter is still much better than on the T-64s and T-72s.

Fans of the T-80U will be happy with with the succeeding T-80BVM, a upgrade of the T-80B with even more advanced ERA and ammunition to cap off the T-64/80 tech tree line.
