The T-84 Main Battle Tank is a Ukrainian development of the Soviet T-80 tank. The T-84 is based on the diesel-engined version, T-80UD. Its high-performance engine makes it one of the fastest existing MBTs in the world, with a power-to-weight ratio of about 26 hp/tonne.

Production history

The T-84 is the latest Ukrainian development of T-64 and T-80 series, designed by KMDB in Kharkiv (while the Russian T-90 is an advanced T-72, with some T-80 features). A main design objective was to make Ukraine's arms industry independent of Russia's, after resulting difficulties in fulfilling a contract to supply T-80 tanks to Pakistan. An external difference from earlier models is the new Ukrainian welded turret, replacing the Russian-built cast one.

The T-84's outstanding feature is the 26 hp/tonne power-to-weight ratio, compared to the T-90's 18 hp/tonne. The tank is also designed to perform well in hot climates, and even includes an air-conditioned crew compartment.

Ukraine has demonstrated several advanced prototypes, intended for international sale.
