T-72B With ERA Main Battle Tank
The T-72B is an upgraded variant of the Soviet T-72 main battle tank (MBT), introduced in 1985 to significantly enhance armor protection, firepower, and combat survivability. One of the most distinguishing features of the T-72B is its integration of Explosive Reactive Armor (ERA), which provides greater resistance against anti-tank guided missiles (ATGMs) and shaped-charge munitions.
This version of the T-72 remains widely used in Russia, post-Soviet states, and various international operators, proving its durability in modern conflicts.
Development and Features
The T-72B was developed to address the shortcomings of earlier T-72 models, particularly in terms of protection and firepower. Compared to its predecessor, the T-72A, the T-72B introduced:
- Thicker composite armor, reinforced with Kontakt-1 ERA, later upgraded to Kontakt-5 on newer versions.
- Improved 125mm smoothbore gun, capable of firing anti-tank guided missiles (ATGMs).
- Upgraded fire-control system, improving accuracy in long-range engagements.
- More powerful engine, providing better mobility and cross-country performance.
Armament and Firepower
- Primary Armament:
- 125mm 2A46M smoothbore cannon, capable of firing:
- APFSDS (Armor-Piercing Fin-Stabilized Discarding Sabot) rounds.
- HEAT (High-Explosive Anti-Tank) rounds.
- HE-FRAG (High-Explosive Fragmentation) shells.
- 9M119 "Svir" (NATO: AT-11 Sniper) ATGM, allowing for long-range precision strikes up to 4,000 meters.
- 125mm 2A46M smoothbore cannon, capable of firing:
- Secondary Armament:
- 12.7mm NSVT heavy machine gun (for anti-air and infantry).
- 7.62mm PKT coaxial machine gun.
- Autoloader System:
- Reduces crew size to three (Commander, Gunner, Driver).
- 8-second reload cycle, improving firing rate.
Armor and Protection
The T-72B with ERA significantly improves battlefield survivability, incorporating:
- Base Composite Armor:
- Improved glacis plate protection, reducing vulnerability to kinetic and shaped-charge threats.
- Thicker turret armor, offering better protection against enemy APFSDS rounds.
- Kontakt-1 ERA (Early Versions):
- Mounted on the turret, glacis plate, and hull.
- Disrupts incoming HEAT and ATGM warheads, reducing penetration effectiveness.
- Kontakt-5 ERA (Later Upgrades):
- Introduced in the late 1980s, providing increased resistance against APFSDS rounds as well.
- Considered a major advancement in Soviet reactive armor technology.
- NBC (Nuclear, Biological, Chemical) Protection System:
- Fully enclosed, overpressure system to protect the crew in contaminated environments.
Mobility and Performance
The T-72B maintains the high mobility of the T-72 platform, featuring:
- Engine: V-84MS 840 hp diesel engine (upgraded from earlier T-72 models).
- Top Speed: 60 km/h (road), 45 km/h (off-road).
- Operational Range: 500 km (700 km with auxiliary fuel tanks).
- Suspension: Torsion bar system, ensuring good cross-country capability.
Operational Use and Combat History
The T-72B with ERA has been widely deployed in multiple conflicts, proving its effectiveness in modern combat scenarios:
- Soviet-Afghan War (limited deployment) – Some T-72Bs used in defensive roles.
- First Chechen War (1994-1996) – Mixed results in urban warfare; lessons learned led to further armor upgrades.
- Russo-Georgian War (2008) – Effective in rapid armor thrusts against enemy forces.
- Russo-Ukrainian War (2014-present) – Heavily used by both Russian and Ukrainian forces, with additional upgrades applied in the field.
Strengths and Weaknesses
✅ Good armor protection with ERA, making it resistant to ATGMs and HEAT rounds.
✅ Strong firepower, including the ability to fire ATGMs from its main gun.
✅ Reliable and relatively easy to maintain, making it a cost-effective MBT.
❌ Vulnerable to top-attack ATGMs, such as Javelins and NLAWs in modern warfare.
❌ Lacks advanced electronics and fire control compared to Western MBTs like the M1 Abrams and Leopard 2.
