Purpose:

protection of main battle tanks (MBT) and infantry fighting vehicles (IFV) from antitank rocket-propelled grenades fired from any kind of launchers, ground-based and helicopter-borne antitank missiles intended to destroy the target by direct impact and in a fly-over attack.                        

System components:

- detection and control equipment: radar, computer, commander's control console, command conversion units;
- countermeasures: protective rounds (PR) and launch cells;
- test equipment.

System features:

• target detection and tracking by a multi-function radar with ‘instantaneous’ view of the entire protected sector;
• aimed engagement of targets by superfast protective rounds of narrow-field action;
• entirely automatic (crew-unattended) operation;
• all-weather day-and-night operation, target detection and destruction under any carrier's operating conditions incl. those on the move and during turret rotation;
• large defended sector in azimuth (220°…270°) that rotates with the turret;
• small dangerous zone (20…30 meters in radius) for accompanying dismounted infantry, no effects on the carrier's external equipment and system components themselves when the protecting round operates;
• sufficient redundancy and possibility of engagement of multiple targets including those from the same direction;
• high counter countermeasure capability and stealth employment;
• rejection of low-speed objects, splinters, bullets, and small-calibre shell explosions, targets moving away from or flying past the carrier;
• system's electromagnetic compatibility with carrier systems and between several APSs when they are used on a group of carriers;
• high safety level.
