The upgraded T-72 MBT is fitted with a weapons-and-fire control system which enables the gunner to fire at stationary and moving targets while the tank is stationary or on the move with a high first round hit probability.
The specific feature of the tank consists in installation of a guided weapon system which enables the gun to fire laser- beam-riding guided missiles and to engage targets with a probability of at least 0.9 at ranges of up to 4000 m. The guided weapon system also enables the tank to engage hovering helicopters which fire from a distance beyond the engagement range of conventional tank armament.
Guided missile can be fired at a moving target while the own vehicle is on the move. The missile is fitted with a tandem warhead to make it possible to defeat targets equipped with explosive reactive armour or modern multi-layer armour with enhanced protection against chemical energy ammunition.
The upgrade ensures the following enhanced capabilities for the gunner:
- increase of effective firing range by day and at night of up to 2000 m when the tank is stationary or on the move
- increase of target detection range by day and night of up to 7000 m, with target recognition range being increased up to 4000 m
- ability to measure target distances of up to 4000 m by day with a probability of 0.9 by means of using a laser range-finder fitted with a amplitude/time selection capability
- capability of firing a guided missile at ranges of up to 5000 m
- automatic allowance for deviation of the current firing conditions from the normal ones with the aid of a high-accuracy digital ballistic computer
The weapons-and-fire control system consists of the following:
- SKAT-M thermal sighting system based on the MATIS thermal camera and fitted with a built-in range-finder
- tank’s guided weapon system consisting of a missile guidance laser beam channel, LKU electronic unit, and 9S601 voltage converter
- tank ballistic computer (LIO-V72)
- muzzle reference system (SUIT)
- gun position sensor (DPP)
- pitch and tilt sensor (DKT)
- tank speed sensor (DST)
- turret traverse sensor (DPB)
- charge temperature sensor (DTZ)
- meteorological sensor (DSA)
- protection unit
- information conversion unit (BPI-72)
The LIO-V72 computer together with TPD-K1 and SKAT-M enable the operator to fire all types of ammunition.
The weapons-and-fire control system carries out automatic calculation of firing data and introduction of the data into the sight or the stabiliser through the ballistic computer.
The SKAT-M thermal sight comprises a gunner’s optronic instrument, monitor and commander’s control panel. The thermal sight enables the gunner to detect and engage targets under almost all weather conditions at big distances and with a high accuracy. This capability is a great advantage when operating in poor visibility or in the hours of darkness. The thermal sight also makes it possible to disregard some common visibility hindrances, such as battlefield smoke.
