A tandem-charge warhead fitted on the missile can defeat targets equipped with explosive reactive armour (ERA) and advanced spaced armour. The missile can be fired on the move against travelling targets. The main gun can also fire a laser guided missile against armoured ground vehicles and hovering helicopters within the range of 5,000m. The ammunition includes high explosive fragmentation (HE-FRAG), armour-piercing fin-stabilized discarding sabot (APFSDS) kinetic energy penetrator, and high-explosive anti-tank (HEAT).

The main gun is fed by a loading system equipped with conveyor, automatic loader, and control system. The Oplot is armed with a smoothbore 125 mm KBA-3 cannon, a KT-7.62 (PKT) coaxial machine gun and a KT-12.7 anti-aircraft machine gun. The combat weight of the tank is 51 tons. The tank has a length of 9.7 m (including the forward-facing gun), a width of 3.4 m without removable side skirts, and a height of 2.8 m.

The commander on the right and the gunner on the left have single-piece hatches.

The driver sitting in the centre is provided with a single-piece hatch cover that opens to the right. The tank has a conventional layout with the driver's compartment at the front, fighting compartment in the middle and engine at the rear, accommodating a crew of three. The BM Oplot is a further development of the prior T-84 Oplot. It is also designed to perform well in hot climates, and includes an air-conditioned crew compartment ( operating temperature range is claimed to be −40 to 55 ☌). The T-84's outstanding feature is a 26 hp/t power-to-weight ratio. Ukraine was forced to sell off four of these to the United States when it struggled to finance the tanks. Ten T-84Ms were delivered from 2001 to 2003. The Ukrainian government eventually made good on its promise to buy the T-84 for the Ukrainian Army. This was marketed to Turkey as the Yatagan, and was trialed there in 2000. The 125 mm caliber gun was replaced with a 120 mm one able to fire NATO ammunition, and designated the T-84-120. 478DU4 gave rise to the T-84 Oplot, which was marketed to Turkey. 478DM appeared at IDEX 1999 as the T-84M. One prototype appeared at International Defence Exhibition (IDEX) in 1995 as the 'T-84 Supertank.' An Ob. 478D with Aynet fire control system and Buran night sight was trialed. KMDB developed a welded turret to replace cast turrets, which were no longer made in Ukraine after the breakup of the Soviet Union. It was first publicly shown at the 1990 Moscow Victory Day Parade, then later in the 1991 Soviet coup d'état attempt. The T-80UD was first deployed to the 4th Guards Tank Division and the 2nd Guards Motor Rifle Division. It was subsequently adopted into service as the T-80UD. The Central Committee settled the debate, siding with the Army. The Soviet Army also opposed a plan to name the tank the T-84, as KMDB had originally envisioned, because it would draw attention to the fact that the Soviets were operating four tanks (T-64, T-72, T-80 and T-84) with more or less similar characteristics. The Soviet Army noted problems with the tank, and full-scale production was delayed to make changes. The government approved production of the Ob.

Prototypes of a less sophisticated model, called Ob. 478B with the 6TD engine were produced by year's end. In September 1985, the government approved the development start of a diesel-powered T-80U. Īfter the death of Ustinov in 1984, the strength of the design bureau of the LKZ began to weaken and the Ministry of Defense started to think seriously about equipping the T-80 tanks with diesel engines. This too was abandoned as it was considered too costly. Improvements included the Sistema fire control system, Shatter active protection system, and a 1,500 hp diesel engine. 478M was a more sophisticated model than the Ob. This quickly became outclassed by the Ob. In 1975, Kharkiv Morozov Machine Building Design Bureau (KMDB) began work on the Object (Ob.) 278, a T-80 powered by a 6TD 1000 hp diesel engine developed for the improved T-64 and T-74. Further work on these was not continued as the main focus at the time was on the gas turbine engine favored by Defence Minister Dmitry Ustinov. The design bureau at Omsk Transport Engineering Design Bureau developed a test bed, called the Ob. Leningrad Kirov Plant (LKZ) began work in 1975 with a diesel 2V16 1500 hp engine on a T-80B chassis. The disadvantages of the gas-turbine engine were readily apparent, and so several design projects were initiated to adopt a diesel alternative. After the adoption of the T-80 tank, the Soviets began improving its design.
