T-72 Tanks: India's Backbone in Modern Armored Warfare

Introduction

The T-72 main battle tank (MBT) is one of the most widely used and battle-proven tanks globally. India, operating over 2,400 T-72 tanks, has significantly relied on these armored vehicles for national defense. Recently, India signed a $248 million contract with Russia’s Rosoboronexport to procure 1,000 HP engines, replacing the older 780 HP engines. This upgrade enhances the mobility, speed, and combat efficiency of the T-72 fleet, ensuring they remain relevant in modern warfare.

Development of the T-72 Tank

• Originally developed by the Soviet Union in the 1970s, the T-72 has been a core component of many armed forces worldwide.

• Designed by Uralvagonzavod, the tank has seen multiple upgrades and modernizations.

• India locally manufactures and upgrades its T-72 fleet at the Heavy Vehicles Factory (HVF) in Avadi, Chennai.

Key Features of the T-72 Tank

1. Firepower

• Armed with a 125mm smoothbore gun, capable of firing APFSDS (Armor-Piercing Fin-Stabilized Discarding Sabot) rounds.

• Equipped with a 7.62mm coaxial machine gun and a 12.7mm anti-aircraft gun.

2. Mobility and Engine Upgrade

• The T-72 was originally powered by a 780 HP engine, limiting its maneuverability.

• With the latest 1,000 HP engine upgrade, the tank achieves greater speed, endurance, and operational efficiency.

3. Armor Protection

• Features composite armor and explosive reactive armor (ERA) to withstand anti-tank missiles and enemy fire.

• Enhanced mine and IED protection ensures crew survivability.

4. Night Combat Capability

• Equipped with thermal imaging and infrared sights, allowing for effective night operations.

• Advanced fire control systems improve target acquisition and accuracy.

5. Operational Range and Endurance

• The T-72 can travel 460 km on-road and 300 km off-road using auxiliary fuel tanks.

• Designed for high-altitude operations, deployed in Ladakh and desert warfare zones.

Significance of T-72 Tanks in India’s Defense Strategy

1. Backbone of the Indian Army

• With 2,400+ units in active service, the T-72 remains the largest tank fleet in the Indian Army.

• Essential for rapid deployment and strategic defense in border conflicts.

2. Cost-Effective Modernization

• Upgrading T-72 tanks is cheaper than acquiring new MBTs like the T-90 or Arjun.

• Ensures combat readiness while reducing operational costs.

3. High-Altitude and Multi-Terrain Capability

• Used effectively in Ladakh, Rajasthan, and Punjab, proving adaptable in diverse terrains.

• Supports mechanized infantry and armored divisions in offensive and defensive roles.

4. Strengthening India-Russia Defense Relations

• The $248 million contract with Rosoboronexport reinforces India’s long-standing defense partnership with Russia.

• Includes Transfer of Technology (ToT) to Armoured Vehicles Nigam Limited (AVNL) in Avadi, enhancing India’s defense manufacturing capabilities.
