Russian-Ukraine War will have larger consensuses on the Indian defense sector and the Indian Navy which operates at least 150 ships and vessels that are powered by gas turbine engines that are supplied by the Ukrainian company Zorya-Mashproekt might face the brunt of the issues in the next few weeks and months due to disturbed supply of critical spares and other components from Ukraine due to ongoing war.
DRDO has used the core of the Kaveri engine to develop a Kaveri Marine Gas Turbine (KMGT) that can generate a modest 12Mw of propulsion power and can be used to power small warships in a class of 2000-2500 tons. According to the Indian Navy, it had requirements of 30-40 KMGT but KMGT in trials failed to maintain desired power requirements for long durations, and also was not able to meet requirements of greater endurance.
Unlike jet engines that need to be replaced after 3000-4000 hours of flight time, Marine Gas Turbines usually have a life span of 30000 hours before its due for engine replacement in any major warships. Indian Navy also needed 42 Gas Turbine generators or GTGs. These are de-rated versions of the marine Kaveri, which will be used for generating electrical power on warships but that too has not materialized yet.
GTRE has plans to develop a Marine Gas Turbine engine based on the 125kN jet engine that it plans to develop with France but it won’t be ready for commercial use at least for 15-20 years. Off late India did diversify and equipped many frontline warships with American General Electric LM2500 on indigenously designed warships, but when it comes to Russian designed warships it still needs to rely on the Ukrainian engines which in future might be replaced by the Russian developed ones but with military sanctions likely to remain in place on Russia for few years that too might be difficult for India.
