Hindustan Aeronautics Limited (HAL) is actively reviewing a proposal from Moscow to locally manufacture or co-produce the Sukhoi Su-57, a fifth-generation stealth fighter.
HAL's Chairman and Managing Director, Dr. D.K. Sunil, recently shared public insights into the progress of these high-level bilateral negotiations.
According to Dr. Sunil, Russian delegates have already delivered comprehensive presentations to the Indian Air Force (IAF) outlining the advanced capabilities of the Su-57.
Concurrently, HAL has performed an internal audit of its manufacturing plants to see how well its current infrastructure could accommodate the production of this new Russian hardware.
Following a site inspection by Russian technical experts, an evaluation concluded that approximately half of HAL’s existing infrastructure is already suitable for Su-57 assembly.
Even so, building a complete and fully functional production line will demand fresh financial investments to upgrade the remaining facilities.
Dr. Sunil confirmed that HAL is currently waiting for Moscow to provide a detailed financial estimate for this required capital.
Once this critical quotation is received, the aerospace company plans to formally present the IAF with the concrete production costs, required manufacturing volumes, and projected delivery schedules.
This latest update aligns with prior observations from Russian engineers, who noted that the specific HAL facilities currently dedicated to building the Su-30MKI are highly compatible with the new stealth jet.
If greenlit, the Su-57 manufacturing model would closely mirror the success of the Su-30MKI programme, ensuring robust participation from the domestic Indian defence industry and the integration of locally developed subsystems.
Recent reports highlight that Russian entities like Rostec and the United Aircraft Corporation (UAC) are fully agreeable to India's technical demands, promising unrestricted technology transfer for crucial components like engines and radar.
For the IAF, Russia's premier stealth fighter is being viewed as a possible stopgap measure to strengthen its combat edge while India's homegrown Advanced Medium Combat Aircraft (AMCA) project is still under development.
The strategic environment—particularly the rapid deployment of stealth fighters like the J-20 and new J-35 by neighbouring China—adds urgency to securing a near-term fifth-generation capability.
To make the deal irresistible and resurrect the spirit of the joint Fifth Generation Fighter Aircraft (FGFA) project that New Delhi exited in 2018, Moscow has offered massive incentives.
These reportedly include complete technology sharing and an exclusive twin-seat variant designed for manned-unmanned teaming (MUM-T) and drone swarm control.
These ongoing developments show that the Su-57 dialogue has moved past basic curiosity and entered a serious phase of evaluating industrial readiness, financial burdens, and practical execution.
Establishing a local manufacturing line for a modern fifth-generation fighter would be a monumental achievement, significantly upgrading India’s domestic aerospace engineering and defence production capacity.
Despite the progress, final approvals are still pending. The ultimate decision rests on thorough cost-benefit assessments, the specific tactical needs of the IAF, and ensuring the purchase does not disrupt the long-term vision of the indigenous AMCA programme.
IAF Chief Air Chief Marshal A.P. Singh has recently maintained a cautious approach, emphasising that the military will strictly follow its standard induction protocols and weigh all options carefully.
Ultimately, the acquisition will only proceed if the Su-57 perfectly aligns with India's broader technological roadmap and future force structure.
