A Russian team studying the feasibility of manufacturing the fifth-generation Su-57 stealth fighter aircraft in India is expected to submit a report on the overall cost that Hindustan Aeronautics Limited (HAL) will incur if both countries decide to proceed with the project, The Indian Express has learnt.
According to sources, the cost report, which is expected this month, will provide a clear picture of the quantum of expenditure needed to manufacture the Russian fifth-generation fighter jets in India, including advanced technologies, human resource, infrastructure, and supply chain development. The Russian team, which includes representatives from the Sukhoi Design Bureau among defence entities, had sent a report to HAL around two months ago, highlighting that HAL already has half the infrastructure in place to produce the fifth-generation aircraft in India.
Sources said this became possible because HAL has been producing the Su-30 fighter aircraft. An Inter-Governmental Agreement for licence production of the Su-30MKI in India was signed in December 2000.

Fifth-generation aircraft leap
Hindustan Aeronautics Ltd already has half the infrastructure in place to produce the fifth-generation aircraft in India as it has been producing the Su-30 fighter aircraft. However, the government has not yet taken a call on which fifth-generation fighter jet would be acquired from a global defence major before its own indigenous fifth-generation fighter jet, the Advanced Medium Combat Aircraft, is finally inducted in the next decade.
HAL’s Nashik division houses the final assembly line for Su-30MKI fighters. Its Koraput division looks after the licensed production and overhaul of AL-31FP turbofan engines, while the Strategic Electronics Factory (SEF) in Kasaragod, Kerala, manufactures avionics components for the Su-30MKIs.
The exercise is an initiative of HAL in order to get an estimate of the investments and its capacity if this fighter jet were to be produced in India.
Officials clarified to The Indian Express that the government has not yet taken a call on which fifth-generation fighter jet would be acquired from a global defence major if it chooses to fill the gap in the Indian Air Force’s fighter squadrons before its own indigenous fifth-generation fighter jet, the Advanced Medium Combat Aircraft, is finally inducted in the next decade.
At a recent event, Air Marshal Ashutosh Dixit, Chief of Integrated Defence Staff (CISC), said there is a gap of about eight to 10 years until India acquires its own fifth-generation aircraft.

“We are thinking right now how that gap (in fighter squadron strength) can be filled. There are various options. I can’t list the platform. We are still working that out,” he had said, adding that fifth-generation capability was being deliberated upon.
In case India does procure a limited number of squadrons of a fifth-generation fighter jet from a foreign defence major as a stopgap arrangement until the arrival of AMCA, it has two key options: the Russian Su-57E and the American F-35 stealth aircraft. Both were showcased at the Aero India 2025 in Bengaluru last year.
In October last year, Russian Ambassador Denis Alipov had indicated that Moscow was willing to support India’s AMCA programme by way of local production of the Su-57. There has been no official word on whether this was discussed during Russian President Vladimir Putin’s visit to India in December 2025.
