Smart top-attack munitions are going to eventually end the present-day tank's reign.

Nah. We're getting close to being able to shoot those things down. The bottom, where the cover is closest, will remain the hardest part to defend.

Smart top-attack munitions are going to eventually end the present-day tank's reign.

Nah. We're getting close to being able to shoot those things down. The bottom, where the cover is closest, will remain the hardest part to defend.

The T-90 features the low silhouette of the earlier Russian tanks, with a low rounded turret centered on the hull, and is fitted with combined passive and active defenses which make the T-90 one of the best protected main battle tanks in the world. The glacis is covered by second generation explosive reactive armor [ERA] bricks, as is the turret. This ERA gives the turret an angled appearance, with the ERA bricks forming a "clam shell" appearance. ERA bricks on the turret roof provide protection from top-attack weapons.

The T-90 is equiped with the TShU-1-7 Shtora-1 optronic counter measures system which is designed to disrupt the laser target designation and rangefinders of incoming ATGM. The T-90 is also equipped with a laser warning package that warns the tank crew when it is being lased. Shtora-1 is an electro-optical jammer that jams the enemy’s semiautomatic command to line of sight (SACLOS) antitank guided missiles, laser rangefinders and target designators. Shtora-1 is actually a soft kill, or countermeasures system. It is most effective when used in tandem with a hard kill system such as the Arena. During the International Defense Exposition (IDEX) held in Abu Dhabi in 1995, the system was shown fitted to a Russian MBT. The first known application of the system is the Russian T-90 MBT that entered service in the Russian Army in 1993. Shtora-1 is currently installed on the T-80UK, T-80U, T-84 and T-90 MBTs.

The Shtora-1 system comprises four key components, the electro-optical interface station, which includes a jammer, modulator, and control panel; a bank of forward-firing grenade dischargers mounted on either side of the turret that are capable of firing grenades dispensing an aerosol screen; a laser warning system with precision and coarse heads; and 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. 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 12 aerosol screen launchers and weighs 400kg. The screening aerosol takes less than 3 seconds to form and lasts about 20 seconds. The screen laying range is between 50-70 meters.
