Arena Active Protection System
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.
