T-72B3

Russia's most numerous upgraded main battle tank — a deep modernization of stored T-72B hulls with enhanced firepower, protection, and mobility, serving as the armored backbone in the war in Ukraine.

Overview

The T-72B3 is a modernized Russian main battle tank derived from the Soviet T-72B. Developed as a cost-effective upgrade to extend the life of thousands of stored T-72B hulls, it combines a 125 mm smoothbore gun, a carousel autoloader, Kontakt-5 or Relikt explosive reactive armor, and a 1,130 hp diesel engine. The baseline T-72B3 (obr. 2011) entered service in 2012; the improved T-72B3M (obr. 2016) followed in 2017, adding Relikt side skirts, a panoramic commander's sight, and other refinements. The type is the most widely fielded Russian tank in the ongoing war in Ukraine, where it has borne the brunt of both offensive operations and attrition.

Development

The T-72B3 program was launched to keep Russia's massive Cold War-era T-72B fleet combat-relevant without the expense of new builds. Uralvagonzavod (UVZ) developed the Obyekt 184-M3 modernization, first revealed in 2011 and adopted by the Russian Ground Forces in 2012. The upgrade replaced the original 840 hp V-84 engine with the 1,130 hp V-92S2F, added a new fire-control system (Sosna-U) with a French Catherine thermal sight (later replaced by a domestic version), and fitted Kontakt-5 ERA, according to Bellingcat. The upgrade program targeted the large stockpile of T-72B tanks, part of the sprawling T-72 family described by Wikipedia. The subsequent T-72B3M (sometimes incorrectly called “T-72B4”) emerged in 2017, incorporating Relikt ERA on the hull sides and turret, slat armor, improved side skirts, and additional upgrades to the fire-control and communication suite, as detailed by Weaponsystems.net. The upgrade program converted over 1,700 hulls at an estimated cost of about 52 million rubles per tank in 2013.
