India's Upgrade Advantage: A New Era for Global Tank Operators

India's Upgrade Advantage: A New Era for Global Tank Operators

In a significant shift in its posture, India has emerged as the most extensively upgraded and customised operator of the T-90 main battle tank, and has now offered similar upgrade packages and long-term support to existing international customers of the platform. This move positions India as a modernisation partner for global tank operators, rather than a mere licensed producer and user of Russian-origin armour.

The Bhishma fleet, built and sustained at the Heavy Vehicles Factory in Avadi under Armoured Vehicles Nigam Limited, has moved well beyond the baseline T-90S configuration supplied to most export customers. The fleet now boasts advanced features like a mid-wave thermal imaging commander sight with an 8-kilometre detection range, developed jointly by DRDO and Bharat Electronics Limited. This sight is paired with an automatic target tracker and a digital ballistic computer derived from the Arjun programme to improve first-round hit probability.

The Defence Acquisition Council has also cleared more powerful 1,350-horsepower engines to address the mobility shortfall the older 1,000-horsepower powerplant faced at high altitude. This upgrade is a significant improvement over the baseline T-90S configuration, which would allow the T-90 to operate effectively in high-altitude environments. Additionally, AVNL has separately floated tenders for electromagnetic turret traverse systems to replace legacy hydraulic drives across the T-90 and T-72 fleets.

India has crossed a significant threshold in May 2026 when the 1,000th indigenously built T-90(IM) rolled out of Avadi with more than 90 per cent indigenous content. The Army has separately contracted for 464 upgraded Mk-3 tanks, which reflects the significant investment India has made in its T-90 upgrade ecosystem.

The T-90 family has been exported to more than ten countries since the 1990s, with Algeria, Azerbaijan, Iraq, Turkmenistan, Uganda, and Vietnam among the largest customers alongside Russia's own fleet. Most of these fleets were delivered in baseline T-90S or T-90SA configuration and have not undergone the scale of sensor, fire-control, and mobility upgrades that India's tanks have received over the past two decades of indigenous development.

This gap between India's heavily modernised Bhishma standard and the comparatively static condition of most export fleets is what reportedly underpins New Delhi's outreach, positioning India's upgrade ecosystem, rather than Russia's original production line, as a potential source of life-extension packages for tanks that are now fifteen to twenty years into their service lives.

For India, offering upgrade support to existing T-90 operators serves multiple objectives simultaneously. It opens a potential export revenue stream for AVNL and its partner firms such as BEL at a time when India's broader defence industry is being pushed toward higher export targets under the Atmanirbhar Bharat framework. It also leverages genuine intellectual and manufacturing capability built up over two decades of local production, rather than requiring fresh investment in an entirely new offering.

For customer nations operating ageing T-90 fleets, many of whom face uncertain access to Russian original equipment manufacturer support given Moscow's own production constraints and the diversion of resources toward the war in Ukraine, an Indian upgrade pathway could offer a more accessible and potentially faster route to modernisation than waiting on Uralvagonzavod's own upgrade programmes.

A New Era for Global Tank Operators

India's upgrade ecosystem, developed over two decades, offers a potential life-extension solution for ageing T-90 fleets worldwide. This move positions India as a modernisation partner for global tank operators and opens a revenue stream for Indian defence firms. Discussions are underway on integrating the Israeli Trophy active protection system into the fleet, which would push India's configuration further ahead of the standard export baseline still in service with most other operators.
