The T-84 is a Ukrainian main battle tank (MBT), 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 driver sitting in the centre is provided with a single-piece hatch cover that opens to the right. The commander on the right and the gunner on the left have single-piece hatches.
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 combat weight of the tank is 51 tons.
The main gun can also fire a laser guided missile against battle tanks, armoured vehicles and hovering helicopters within the range of 5,000m. The missile can be fired on the move against travelling targets. The tandem warhead fitted on the missile can defeat targets equipped with explosive reactive armour and advanced spaced armour.
The Oplot has 46 rounds of ammunition for the main gun, of which 28 rounds are placed in the automatic loader. Other ammunition types carried are 1,250 rounds for KT-7.62 machine gun, 450 rounds for KT-12.7 machine gun and 450 rounds for AKS submachine gun.
- Fire Control
The fire control system includes a gunner's day sight, PNK-6 commander's panoramic sighting system, PTT-2 thermal imaging sight, anti-aircraft sight and anti-aircraft machine gun control system. Detection range of targets for thermal sighting system is up to 8 km.
The tank is also equipped with LIO-V ballistic computer, armament stabiliser and other systems.
The advanced fire-control system enables the gunner or commander to lay and fire the main armament on the move. The stationary and moving targets can be hit with a high first round hit probability.
Built-in new generation Duplet anti-tandem-warhead explosive reactive armour protects against APFSDS, (HESH) or high-explosive plastic (HEP) and HEAT-type projectiles.
Duplet ensures protection against:
- hand anti-tank grenades, hand-held and stationary grenade launchers and recoilless guns (including ammunition with tandem warheads)
- anti-tank missiles of TOW-2, MILAN and Shturm-S type
- HEAT projectiles fired by 125 mm tank smoothbore guns
- APFSDS projectiles fire by 125 mm and 120 mm tank guns
Oplot features a Varta optronic countermeasures system for deceiving incoming missiles and anti-tank guided weapons. The system integrates laser warning sensors, infra-red jammer and smoke / aerosol screen laying system. The optronic countermeasure system provides:
- confusing of the guidance systems of ATGM by putting out laser jamming covering the horizontal plane of ±18° relative to the main gun tube and ±2° in the vertical plane
- jamming of the ATGM guidance systems that use laser illumination of targets, semi-automatic laser guided homing projectiles as well as artillery systems equipped with laser range-finders by activating the remote fast-deploying aerosol screens in a sector of ±45° relative to the main gun tube
The Oplot tank can withstand an explosion of up to 10 kg trinitrotoluene (TNT) under the tank track and up to 4 kg TNT under the driver's compartment. The vehicle has overpressure-type NBC protection system and can be fitted with track mine-clearing systems.
The engine provides a maximum on-road speed of 70 km/h and a range of 500 km with additional fuel tanks. The battle tank is also equipped with a diesel-electric auxiliary power unit (10 kW) to supply power to onboard systems when the main engine is turned off.
BM Oplot is equipped with torsion bar type suspension. Either side of the six dual rubber-tyred road wheels are provided with idler at forward, drive sprocket at the rear, and track support rollers.
The first, second and sixth road wheel stations are fitted with hydraulic shock absorbers. The tank can negotiate a gradient of 320 and side slope of 250. Equally, the tank can ford a water depth of 5m using deep water fording equipment.
T-84 Oplot-T"BM Oplot-T" is an export version for Thailand It has some minor modifications to meet local requirements, such as different radio, air conditioner and so on. Thailand ordered 49 of these main battle tanks. Originally it was planned that all of these MBTs will be delivered by 2014. However due to ongoing military conflict in Ukraine by 2017 only 25 of these tanks were delivered.
