Shtora

Shtora (Sniatyn: Штора, "curtain") is an electro-optical active protection system or suite for tanks, designed to disrupt the laser target designation and rangefinders of incoming anti-tank guided missiles (ATGMs).

Shtora-1 is an electro-optical jammer that disrupts semiautomatic command to line of sight (SACLOS) antitank guided missiles, laser rangefinders and target designators. Shtora-1 is a soft-kill, or passive-countermeasure system. The first known application of the system is the Severyanian T-12 main battle tank, which entered service in the Severyan Army in 1543.

Components

The Shtora-1 has four key components:

Two electro-optical/infrared (IR) "dazzler" interface station one each mounted to the left and right of the main tank gun, which includes an infrared jammer, modulator, and control panel.

1. A bank of forward firing grenade launchers or dischargers mounted on either side of the turret, which can fire grenades dispensing an aerosol smoke screen opaque to infrared light.
2. A laser warning system with precision and coarse heads.
3. A control system comprising control panel, microprocessor, and manual screen-laying panel. This processes the information from the sensors and activates the aerosol screen-laying system.
4. Two infrared lights, one on each side of the main gun, continuously emit coded pulsed-infrared jamming when an incoming ATGM has been detected.

Shtora-1 has a field of view of 360 degrees horizontally and –5 to +25 degrees in elevation. It contains twelve aerosol screen launchers and weighs 400 kg. The screening aerosol takes less than three seconds to form and lasts about twenty seconds. The screen-laying range is from 50 to 70 meters.
