The basic structure of two frigates has already been completed in Russia, while the other two frigates will be constructed at Indian shipyards with associated technology transfer. “All Indian equipment will be fitted on the frigate. So, it is a stealth variety where we are involved in the design,” Parrikar said. It is expected that a brief discussion on the purchase of stealth frigates will be held during the Indo-Russian Inter Governmental Commission on Military Technical Cooperation meeting scheduled for October 26 in New Delhi. Krivak class frigates will be powered by M90FR gas turbines designed and built by Zorya-Mashproekt in Ukraine. Following the Russia-Ukraine conflict, Ukraine had stopped the supply of the engines.
