BALLISTIC PROTECTION
Main passive armour protection
Type - anti-projectile, combined, multi-layer, against penetration of HEAT and APFSDS projectiles (adapted for installation of explosive reactive armour array)
Built-in anti-tandem-warhead explosive reactive armour (BATW-ERA)
The BATW-ERA array is intended to increase the tank's level of protection against kinetic energy (APFSDS) and chemical energy ammunition (HEAT, HESH, HEP), including ammunition with tandem warheads.
The armour protection fitted with BATW-ERA 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
The BATW-ERA array consists of glacis module and side skirts installed on the tank hull, as well as modular elements placed on the outer perimeter of the front and side surfaces of the turret and containers installed on the turret roof.
The Nozh explosive reactive armour elements installed in special niches snap into action when hit by all types of hollow-charge warheads and sub-calibre armour-piercing projectiles.
The Nozh explosive reactive armour elements of the BATW-ERA do not detonate when hit by 12.7 mm bullets, 30 mm armour-piercing projectiles and shell fragments. The Nozh explosive reactive armour elements do not require any maintenance and are safe to deal with.
The Nozh explosive reactive armour elements are stored in containers or on the tank in heated premises or in the open air under a shed protecting them against precipitation and solar irradiation at temperatures from -50 to +55 degrees Centigrade. They can also be stored under the conditions of high humidity (100%) at temperatures of up to +35 degrees Centigrade.
The Nozh explosive reactive armour elements retain their qualities for 10 years, including storage in field conditions for up to 5 years and use on the tank for up to 3 years if the requirements for use, transportation and storage are met.
It takes the tank crew 2.4 to 2.6 hours to prepare the BATW-ERA array for combat operation within without the need to use any special contrivances (to do this, only the explosive reactive armour elements are to be installed).
Anti-mine protection
The anti-mine protection makes it possible to preserve the combat readiness of the crew and operability of the tank's interior equipment in case an anti-tank mine explodes under the tank track (up to 10 kg TNT equivalent) or under the tank driver's compartment bottom plate (up to 4 kg TNT equivalent).
SPECIAL PROTECTION MEANS
Optronic countermeasures system
To improve the tank protectability, the Varta optronic countermeasure system is integrated in the tank.
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

Crew’s collective protection system
The system ensures protection of the crew and interior equipment against effects of nuclear explosions, radioactive substances, toxic agents and biological warfare agents, as well as detection and suppression of fires in the crew compartment and power pack compartment.
NBC protection system
PRHR-M1 radiation and chemical agents detector
PRHR-М1 (RCAD) is designed for continuous check-up, detection, signalling and control using actuators of protection means:
- during intensive gamma- radiation (nuclear blast)
- during gamma-radiation on the contaminated terrain followed by measuring the doze of radiation
- during detection of poisonous vapors in the air as a result of enemy actions
The instrument provides light and audible signals in case of detection poisonous agents in the air or gamma-radiation on the terrain as well as it generates commands for switching blower on and shifting over the valve of filtering ventilation unit (FVU) in the filtering position.
The instrument provides light and audible signals in case of detection powerful gamma radiation as well as commands for engine shutdown, shifting over the valve of FVU in the filtering ventilation mode, switching off the blower if it was on, followed by switching it on in 30 to 50 s.
The instrument provides checking its electrical circuits by generation commands (or without command generation) to actuators.
Range of measuring power of gamma radiation exposure doze

Filter-ventilator unit
The filter-ventilator unit serves to clean external air from poisonous substances, radioactive dust, biological aerosols, to supply cleaned air into the crew compartment and create overpressure in it, as well as to ventilate the crew compartment during firing and fire fighting system comes into action.
