INDIA WATCH: From Mykolaiv to Make-in-India

INDIA WATCH: 

From Mykolaiv to Make-in-India

How the Navy is finally getting its own heartbeat 

Ending 40 years of Ukrainian turbine dependence 

For four decades, the roar under the deck of almost every Indian frontline warship was Ukrainian.

The Rajput-class, the Delhi-class, the Visakhapatnam-class destroyers, our Talwar frigates — all sailed on Zorya-Mashproekt gas turbines built in Mykolaiv. 

It was a good, Soviet-legacy marriage. Until the war made it a hostage situation.  

When Russia hit the Zorya plant in 2022, the supply line froze. As one widely shared defence briefing put it this May, thirty frontline destroyers and frigates were suddenly looking at a maintenance blackout — the fleet effectively "PARALYZED". That is vulnerability and why New Delhi finally moved.  

This is not about nationalism. It is about physics and logistics. 

A warship without a secure engine is a museum.

1. The Chokepoint we lived with

Marine gas turbines are cruel engineering. They have to survive salt corrosion, start in seconds for a tactical sprint, and deliver an enormous power-to-weight ratio in a cramped hull.  

Ukraine had that mastery. We bought it. And we paid for it in 2022, when spares, overhauls, and new builds for the Talwar follow-ons all stalled as the conflict severed the supply and maintenance lines.  

The Navy learned what the Air Force learned with the Kaveri: you can import a hull, you can import a missile, but if you cannot turn the shaft, you do not sail.

2. Three tracks to break free

India is not betting on one silver bullet. That is what makes this pivot real.

Track A — The big ship heart: BHEL

Bharat Heavy Electricals has indigenised a 40 MW class marine gas turbine, leveraging 30 years of power-sector turbine work into a full domestic design — compressors, combustors, turbine sections and gearboxes included.

The social feeds in May were full of that BHEL infographic you sent — the silver turbine on the dockyard with D67 in the background — celebrated explicitly as "ending dependence on Ukrainian Zorya-Mashproekt engines", with follow-on carousels showing installation and Digital Twin health monitoring.  

Track B — The DRDO long game: Kaveri Marine

The Gas Turbine Research Establishment's Kaveri Marine Gas Turbine, KMGT, is the indigenous clean-sheet. It is still maturing — "still in the development phase and has not yet matured to the point where it can be reliably deployed" was the frank assessment in October 2024. Output is in the 12-15 MW class, ideal for corvettes and future frigates. It is slow, it is hard, and it is essential.  

Track C — The pragmatic bridge

While KMGT bakes, the Navy went with what floats now: GE LM2500s, 30 MW, proven on the Shivalik, Nilgiri and INS Vikrant classes, assembled in India by HAL.  

At the same time, the lower end is being Indianised fast:

• Bharat Forge just signed a ₹425 crore contract for 12 sets of 1.25 MW Marine Gas Turbine Generators for Kolkata-class vessels, with 60% indigenous content   

• Kirloskar is building India's first indigenous 6MW V12 marine engine for the Navy, contract signed April 2025, delivery target 2028   

• A new private-sector MRO complex is coming up in Visakhapatnam with Bharat Forge, cutting turbine overhaul turnaround from months overseas to a claimed 72 hours at home   

A recent IDU briefing also flagged a Navy MAKE-I program for a 28 MW Indigenous Gas Turbine, with HAL, BHEL and GTRE partnered, four prototypes then at least forty production engines.  

That is the full ecosystem: big turbines, small gensets, MRO, and design bureaus. That is how you break a dependency, not with a press release.

Why this changes maritime security 

1. Lifecycle sovereignty. A warship serves 35 years. Indigenous production guarantees spares, upgrades and overhauls without waiting on a foreign OEM.   

2. Build-rate freedom. Mazagon and GRSE can lay down hulls on our schedule, not Mykolaiv's. 

3. Export leverage. A BHEL-powered frigate with no ITAR or war-zone strings is a very attractive offer to the Global South.   

As the BHEL announcement put it bluntly: this secures "propulsion sovereignty for the Indian Navy".  

Closing note 

The romance of naval power is usually missiles and carriers. The reality is metallurgy. Turbine blades that survive 1,560K, salt spray, and a full-ahead flank order at 2 am.

We spent 40 years renting someone else's heartbeat. The Ukraine war was a brutal teacher, but a clear one.

The shift to indigenous naval engines will not be loud. It will be a low, steady whine in an engine room in Karwar, built in Hardwar, maintained in Vizag. That is strategic autonomy. That is maritime security.

And that is a column worth writing.
