T-84 MBT - Other Features

The T-84 MBT standard equipment also includes an auxiliary power unit, provision for deep fording, satellite navigation support system, self-entrenching device (dozer blade), electric bilge pumps as well as internal and external communications equipment. A crew compartment heater and power pack preheating are also provided for operation at low temperatures.

The T-84 is fitted with an EA-8 under-armour diesel auxiliary power unit (APU) developing 8 kW. This allows the vehicle to run key subsystems without the main engine running (for instance, when the tank is operating from a static fire position or when the vehicle is on silent watch). The APU is mounted at the rear of the hull on the right side.

The deep fording equipment enables the tank to cross water obstacles to a water depth of 5 m (1.8 m deep water obstacles can be crossed without preparation). When fording, the T-84 retains its full nuclear, biological and chemical protection. After the vehicle leaves the water obstacle, the deep fording equipment pipes can be immediately jettisoned with the help of a quick-release mechanism; in so doing, the crew members do not have to leave the vehicle.

The navigation support system is based on the GLONASS and NAVSTAR systems. The system gives the tank commander his own vehicle position and bearing, as well as friendly force location. This makes it easier to control the friendly force manoeuvres, which is especially important when operating in a closed-down vehicle, at night and in misty or smoky conditions. The system also gives various other information such as steering direction to the driver to ensure the vehicle's movement towards the pre-selected destination point.

The navigation support system enables the tank commander to transmit information (including encoded information) through a digital communication channel by using the standard radio set. This feature represents a key element in command and control system which will be enhanced at a future date or adapted according to a specific customer's requirements.

The self-entrenching device is mounted under the front of the hull and enables the tank to dig up a tank caponier within 15-40 minutes (this depends on the structure of the soil).

The communications equipment consists of an R-173M VHF radio set, an R-163-50K HF radio set, and a crew intercom system.

To carry out mine-clearing operations, the T-84 can be fitted with various types of plough and roller-type mine-clearing systems at the front of the hull including KMT-6 plough-type system and KMT-7 roller-type system, both systems being designed for quick installation on the vehicle at unit level. The vehicle hull front is fitted with attachment points for the systems.

In the standard version, the T-84 has no air-conditioning system, but as an option, the Ukrainian-made KTT air conditioning system can be fitted. With an outside temperature of 55 C, the air conditioning system maintains interior temperature at +15-20 C. The cooled interior compartment improves electronics reliability and improves crew performance.

The T-84 MBT design is flexible and could be customised to meet other users' specific operational needs. The options being offered for the export market include an air conditioning system (see above), German-designed sophisticated navigation system, Belgian-made coaxial and anti-aircraft machine guns, French-designed radio equipment an so on. The tank design is modular and its components can be modified over time to cater for changes in the threat posed by the new generations of sophisticated anti-tank weapons as well as being further improved as advanced technologies become available, or slightly modified to suit varying tactical requirements and combinations of firepower, protection, and mobility. A number of technical improvements are currently in development, including sophisticated battle management system with digital map display (which can greatly increase awareness of the tactical situation enabling tank units to react more quickly and reduce crew work-load as well as the risk of fratricidal fire), automatic target tracking in the fire-control system (which enhances its ability to engage moving targets or on the move, eliminating the gunner's tracking error), battlefield 'identification friend or foe' system, electronic engine management, inter-vehicle digital communication etc.

Nowadays, when the prominent role of main battle tanks on the battlefield is being called into question as the tanks are mostly used in tank-versus-tank engagements, the T-84 is designed as a fighting vehicle with multi-purpose capabilities that is able not only to destroy tanks but also to carry out a wide variety of secondary tasks as well as capable of engaging a wide variety of targets, including lightly armoured or unarmoured vehicles, men in the open and protected pinpoint targets such as emplacements or fortified positions.
