Fire Control System The vehicle incorporates a multi-channel day/night optical electronic suite.
Weapons The weapon set of the 2T Stalker comprises a stabilized
30 mm caliber automatic cannon, a
coaxial machine gun, an
automatic grenade launcher, as well as four ready-fire missiles; two
anti-aircraft and two
anti-tank missiles. The gas-operated gun is a dual feed multipurpose small caliber weapon, The sustained rate of fire is 200 rds/min, though. The missile has replaced the older
3M11 Falanga (AT-2 Swatter) on the
Mi-24 Hind attack helicopter, yet the SACLOS system with IR missile tracking, and radio guidance, similar to the uprated version of the Swatter, the AT-2c, operates the same as the
AT-4 Spigot and
AT-5 Spandrel which unlike the AT-6 Spiral are wire-guided. however, that is as incorrect as the erroneous crediting of the missile with 7,000-10,000 meters as the maximum range. The conventional shaped-charge warhead of the basic Shturm is believed to ba capable of penetrating 560-600mm of armor, where the warhead that contains two tandem HEAT charges would punch through 600–700 mm of rolled homogenous steel armor (
RHA). =====Anti-Air missiles (
SA-18 Grouse)===== The
9K38 Igla (
NATO reporting name is S-18 Grouse) is a 72.2 mm
man-portable air defense missile weighing 10.6 kilograms with a 1.3 kilogram warhead. The missile itself is 1.67 meters long, the container is 1.708 meters and the whole system weights 17 kilograms. The system is designed to engage
fixed-wing and
rotary-wing aircraft,
cruise missiles and
UAVs flying at speeds of 360–400 m/s in head-on engagement (approaching target) and up to 320 m/s in tail chase (receding target) within their optical visibility and in the night-time conditions in background clutter and thermal countermeasures environment. The system uses thermal battery/gas bottle, and is armed with a
high-explosive warhead fitted with a
contact and grazing
fuse. The missile has a maximum range of 5200 meters and operates at altitudes from ten and up to 3500 meters. The 9M39 missile SA-18 employs an
IR (infrared)
guidance system using proportional
convergence logic. The new seeker offers better protection against electro-optical jammers; the probability of kill against an unprotected fighter is estimated at 30-48%, and the use of
IRCM jammers only degrades this to 24-30%. ==Comparable vehicles==
