   The T-72B3 is a recent Russian upgrade of the ageing T-72B tanks. It can be seen as a low-cost alternative to the T-72B2 Rogatka upgrade to keep older T-72B tanks operational. Refurbished and upgraded T-72B3 tanks are fitted with new engine, new gunners sight, new fire control system and have some other improvements. Now this MBT has a hunter-killer capability. First upgraded T-72B3 tanks were delivered to the Russian Army in 2013. By 2016 At least 600 older tanks were upgraded to this standard.

   During 2014 and 2015 the T-72B3 tanks saw combat during a military conflict in Ukraine. At least a couple of these tanks were captured by Ukrainian armed forces and pressed into service against the Russians.

   Protection of the upgraded tank was slightly improved. The T-72B3 is fitted with built-in Kontakt-5 explosive reactive armor. The same armor is used by the T-80U, T-90 and some other main battle tanks. This armor can effectively defeat most older APFSDS rounds.

   The tank is armed with the same 125-mm smoothbore-gun as its predecessor. However autoloader of the T-72B3 has some modifications and can use newly-developed munitions. This tank can launch 9M119 Svir or 9M119M Refleks anti-tank guided missiles in the same manner as ordinary projectiles. Western reporting name for both missiles is AT-11 Sniper. A total of 45 rounds are carried, 22 rounds are stored in the autoloader and ready to use, while remaining are stored inside the hull.

   There is a coaxial 7.62-mm machine gun and roof-mounted 12.7-mm machine gun. The roof-mounted 12.7-mm machine gun is controlled manually by the vehicle commander.

   The tank has new fire control system and new ballistic computer. Gunner uses new Sosna-U sight with thermal imager. This sight has day/night and all weather combat capability. The T-72B3 has a hunter-killer capability even though it lacks commander's panoramic sight. Vehicle commander can select a target and lay the gun and let the gunner complete all the aiming and firing process. During that time commander looks for the next target. The tank is also fitted with new digital radio system.

   Some T-72B3 demonstrator tanks were fitted with commander's panoramic sight. This sight might appear on later models.

   This tank has a crew of three, including commander, gunner and driver.

   Initially refurbished and upgraded T-72B3 tanks were powered by original V-84-1 diesel engine, developing 840 hp. However later production tanks were fitted with a new V-92S2F engine, developing 1 130 hp. This tank is also fitted with new tracks.

   There is also an improved T-72B3M version of this tank, also called T-72B4. It has a new A246M5 gun. It is reportedly fitted with a built-in Relikt 3-rd generation explosive reactive armor. This tank is powered by the V-92S2F diesel, developing 1 130 hp.
