Proposed Indo-Russian facility promises spares, technology transfer, and long-term readiness boost for Indian Navy’s Russian-origin warships
In a significant move to address India’s long-standing naval propulsion gap, Russia has renewed its offer to supply M-90FR marine gas turbines to the Indian Navy, coupled with a proposal to set up a local manufacturing line in India.
This initiative was discussed during President Vladimir Putin’s December 2025 visit to New Delhi and marks a strategic effort to end India’s dependency on Ukrainian engines for key warship classes.
Ukraine War Exposes a Critical Vulnerability
Several Indian Navy frontline vessels—especially Talwar-class frigates, Krivak III-class corvettes, and Project 1135.6 ships—depend on Ukrainian Zorya-Mashproekt turbines.
Since the Russia–Ukraine war began in 2022, spare parts delivery has nearly ground to a halt, affecting:
- Up to 40% of the affected fleet
- Maintenance cycles, with delays in components like turbine blades and fuel systems
- Overall combat readiness in India’s blue-water operational theatres
“This vulnerability has forced emergency workarounds, but it’s unsustainable for blue-water operations,” noted a senior Indian naval officer.
The M-90FR: Russia’s Answer to India’s Engine Woes
Designed by UEC and NPO Saturn, the M-90FR is a 20MW-class marine gas turbine now in serial production.
Key features:
- 25% higher efficiency over older DT-59 engines
- Afterburning capability: 19,500 shp cruise / 27,000 shp max
- Modular hot section for rapid overhaul
- Supports up to 70% biofuel blend—aligning with India’s green propulsion goals
- TBO (Time Between Overhaul) extended to 10,000 hours
- Lifecycle cost reduction of up to 20% through reduced vibration and improved maintenance predictability
What’s New: A Local Production Line in India
Unlike earlier proposals, Russia is now offering:
- Full technology transfer
- A dedicated production and assembly line for M-90FR engines and spares
- Potential locations: GRSE (Kolkata) or a new greenfield site near Mumbai
- Local expertise in single-crystal turbine blade forging
- Use of digital twin simulation for predictive maintenance
This could enable 60–70% indigenous content within five years, significantly improving India’s naval industrial resilience.
For the Indian Navy, the proposal could deliver:
- Operational recovery for idle or underperforming frigates
- Support for two new Talwar-class ships under construction
- Interim capability while awaiting the Kaveri Marine Gas Turbine (KMGT) program’s maturity
- A more predictable maintenance ecosystem, reducing foreign dependency
Retired Rear Admiral Sanjay J Singh emphasized the long-term value, calling the offer a “bridge to self-reliance while sustaining current assets.”
Looking Ahead: Indigenous Alternatives and Fleet Modernisation
While DRDO is progressing on the KMGT, it remains years from fleet induction. In the meantime:
- M-90FR integration offers a drop-in upgrade path
- Plug-and-play design ensures faster retrofit into existing Russian-origin hulls
- Enables fleet standardization for long-term maintenance planning
This fits India’s evolving naval strategy to reduce foreign risk exposure while still enhancing combat readiness and maritime reach.
