The T-84 is a Ukrainian main battle tank, a development of the Soviet T-80 main battle tank. It was first built in 1994 and entered service in the Ukrainian Armed Forces in 1999. The T-84 is based on the diesel-engined T-80 version, the T-80UD. Its high-performance opposed-piston engine makes it one of the fastest MBTs in the world, with a power-to-weight ratio of about 26 horsepower per tonne (19 kW/t). The T-84 Oplot is an advanced version incorporating an armoured ammunition compartment in a new turret bustle; ten of these entered Ukrainian service in 2001. The T-84-120 Yatagan is a prototype model intended for export, mounting a 120 mm gun capable of firing standard NATO ammunition and guided missiles.

The T-84 is the latest Ukrainian development of the T-80 series, designed by KMDB in Kharkiv. 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-80UD tanks to Pakistan. An external difference from earlier models is the new Ukrainian welded turret, replacing the T-80's Russian-built cast turret (some T-80s shipped to Pakistan were fitted with the T-84 welded turret, but lack other T-84 improvements).

The T-84's outstanding feature is the 26 hp/t power-to-weight ratio. It has inherited the nickname Flying Tank from the T-80. The tank is also designed to perform well in hot climates, and even includes an air-conditioned crew compartment (operating temperature range is claimed to be -40 °C to 55 °C).

Due to the collapse of Soviet Union, the Malyshev Factory was no longer able to obtain ceramic armour modules from Russia and only the initial batch of T-84 were produced with such. Instead, later batches of T-84's composite armour is composed of special purpose rubber sandwiched between steel and alloy plates. The exact comparison of new and previous armor performance is not known and highly depend on performance of dynamic armor which continuously improved.

Ukraine has demonstrated several upgraded prototypes of this tank, intended for both domestic employment and international sale.


The first T-84 prototype vehicle rolled out in 1994, and in the same year it was decided to build several more vehicles. They were subjected to extensive company and army trials. After successful completion of the extensive trials programme in the late 1990s the T-84 MBT entered service with the Ukrainian Army in 1999. On 24 August 2000, 10 T-84 MBTs took part in the parade dedicated to the 10th anniversary of Ukraine's independence.

In 2014, the T-84 first saw action during the War in Donbass.


In September 2011, The Malyshev Plant, based in Kharkiv, announced plans to produce the first batch of five Oplot-M tanks for the Thai Army by the end of the year. Under the contract, the Ukrainian company will make 49 tanks worth over USD 200 million.


In October 2009, Ukrspetsstroi plans to sell to Georgia 12 modern T-84 Oplot tanks, among other weapons.
