T-72S Main Battle Tank, Russia
The Russian T-72 main battle tank was produced at the Malyshev HMB Plant, based in Kharkov, Ukraine and at UKBM Nizhny Tagil, Russian Federation and produced under licence in a number of countries. The T-72 first entered production in 1972 and an estimated 50,000 have been built.
The T-72 has been exported to: Algeria, Bulgaria, Cuba, the Czech Republic, Slovakia, Finland, Hungary, India, Iran, Libya, Myanmar, North Korea, Poland, Romania, Syria and Yugoslavia.
Hungary donated 77 T-72 tanks to the government of Iraq in November 2005. As of 2009, the Iraqi Government was planning to purchase 2000 T-72 tanks along with modernisation of the T-72S tanks and Venezuela was planning to purchase 92 Russian T-72 tanks.
The T-72A tank was in production until 1985, along with export versions T-72M and T-72M1. The T-72B entered production in 1985. The export version of the T-72B, the T-72S has a new engine and suspension system and is configured for mounting explosive reactive armour (ERA).
T-72S main battle tank armament
The tank is fitted with a 125mm D-81 smoothbore gun, a 7.62mm co-axial machine gun and a 12.7mm air defence machine gun mounted on the commander's cupola. The T-72S carries 45 rounds of 125mm ammunition, 22 rounds of which are carried on an automatic loading carousel.
The gun fires separate loading armour-piercing discarding sabot rounds (APDS), high-explosive anti-tank (HEAT) rounds and high-explosive fragmentation (HE-FRAG) projectiles. Fire accuracy is attained by a laser rangefinder sight, ballistic computer and a thermal barrel sleeve. Dual-axis stabilisation ensures effective firing on the move.
The tank's anti-armour missile system is the 9K120 Svir (Nato codename AT-11 Sniper), designed by the KBP Instrument Design Bureau, Tula.
The system is intended to engage tanks fitted with ERA as well as low-flying air targets. It has a range of 100m to 4,000m and firing requires the tank to be stationary.
The system's 9M119 missile has semi-automatic laser beamriding guidance. The gun's automatic loader will feed both ordnance and missiles.
