What It Is
The T-72 Main Battle Tank has been the backbone of the Indian Army's armoured corps since the early 1980s. India licence-built the Soviet T-72 M1 at the Heavy Vehicles Factory (HVF) in Avadi (now AVNL), initially with knock-down kits and progressively with increasing indigenous content. The tank entered Indian service as the 'Ajeya' and formed the core of armoured regiments deployed along the western (Pakistan) and northern (China) borders. With a mass of approximately 41 tonnes, a 125mm 2A46 smoothbore gun with an autoloader, and a V-46-6 V-12 diesel engine producing ~780 hp, the T-72 offered a compact, hard-hitting platform suited to India's operational requirements. India's fleet has undergone progressive modernisation under the CIRUS and UpG programmes, incorporating improved fire control systems, thermal imaging, ERA packages, and enhanced communications. The T-72 remains in widespread frontline service, with newer platforms like the T-90S Bhishma and the indigenous Arjun Mk-1A supplementing — but not replacing — the fleet.
Deployments & Procurement
India licence-built approximately 1,500+ T-72 tanks at HVF Avadi from the 1980s onwards, with the majority delivered by the mid-1990s. The fleet is deployed across armoured corps formations on the western and northern borders. Modernisation programmes (CIRUS/UpG) continue to upgrade the fleet with indigenous fire control and ERA packages.
| Agency | Context | Year | Quantity / Note | Sources |
|---|---|---|---|---|
| Indian Army (Armoured Corps) | Licence production — T-72 M1 / Ajeya | 1988 | First batch delivered ~1988; ~1,500+ produced at HVF Avadi through the 1990s | [1] |
| Indian Army | CIRUS / UpG modernisation | 2010 | ~1,000+ tanks modernised; upgraded fire control, thermal imaging, ERA | [1] |

Import Dependencies
Originally licence-built with full Soviet technology transfer. Modernisation packages have progressively increased indigenous content, though certain subsystems remain imported.

FAQ
How does the T-72 compare to the T-90 in Indian Army service?
The T-90S Bhishma (def-019) is a more advanced evolution of the T-72 family with improved composite and ERA armour (Kontakt-5), a more powerful V-92S2 engine (~1,000 hp), Shtora-1 IR jammer, and the 1A45T fire control system. The T-72 remains more numerous (~1,900 vs ~1,200+ T-90S) and forms the backbone of armoured formations, while the T-90S is deployed as the premium frontline MBT. Both share the 125mm smoothbore gun and autoloader, enabling common logistics for ammunition.

What is the CIRUS / UpG modernisation programme?
The CIRUS (Combat Improved Indian Original T-72) and UpG programmes are Indian modernisation initiatives to upgrade the T-72 fleet with improved fire control systems, thermal imaging sights, explosive reactive armour (ERA) packages, digital communications, and enhanced ammunition. The programme aims to extend the operational life of the T-72 fleet and bridge capability gaps until newer platforms are fielded in sufficient numbers.
Sources: [1]
Is the T-72 being phased out of Indian Army service?
Not yet. While newer platforms (T-90S Bhishma, Arjun Mk-1A, and the Zorawar light tank for high-altitude) are supplementing the fleet, the T-72 remains the single most numerous tank in Indian Army service. Modernisation programmes are extending its life, and full retirement is likely to be a gradual process spanning the 2030s and beyond.
