Indian Army’s T-72 and T-90 Tanks to Get Indigenous Power Upgrade Under ₹586 Crore Deal

The Indian Army’s T-72 and T-90 tank fleet is set to receive an indigenous power-system upgrade after the Ministry of Defence signed a ₹586 crore contract with Accurate Industrial Controls Private Limited. The contract was signed in New Delhi on September 21, 2026, in the presence of Defence Secretary Rajesh Kumar Singh.

The agreement, signed in New Delhi on September 21, 2026, covers the procurement of Auxiliary Power Units (APUs) for the two armoured platforms. The contract is being executed under the Make-II category, which is intended to encourage Indian industry to develop and manufacture defence equipment and technologies.

The APU will function as an additional power source for the tank when its main engine is not required to be running. It is designed to support several critical electrical and electronic systems, including the fire-control system, firing circuit and gun stabilisation system.

For armoured vehicles, the ability to power essential systems while remaining stationary can have operational and logistical benefits. Instead of operating the main engine solely to generate electrical power, the auxiliary system can provide the required electricity independently. This can help reduce unnecessary engine running, fuel consumption and wear during stationary periods.

The development is particularly relevant to India’s existing armoured fleet, where the T-72 and T-90 tanks continue to form a major part of the Indian Army’s mechanised formations. Rather than replacing these platforms, the APU procurement is aimed at improving the supporting systems that enable them to operate effectively.

The contract also reflects the increasing focus on developing critical defence subsystems within India. Accurate Industrial Controls is undertaking the work as an Indian industry partner under the Make-II framework, providing an example of private-sector participation in the development of specialised military equipment.

The Ministry of Defence has identified the indigenisation of critical components and subsystems as an important part of strengthening India’s defence manufacturing capabilities. Indigenous solutions for established platforms can also help reduce dependence on external suppliers while creating opportunities for Indian companies to contribute to military modernisation.

The ₹586 crore agreement consequently combines two objectives: improving the power-management capability of the Army’s T-72 and T-90 tanks and expanding the domestic industrial base for specialised defence technologies. The induction of the APUs is expected to contribute to the reliability, sustainability and operational readiness of India’s mechanised forces.
