In 1986, the Cabinet Committee on Political Affairs (CCPA) decided to diversify India's warship building capability, and start an alternate production line to the ''Godavari''-class frigates that were built at [[Mazagon Dock Limited]] (MDL) in [[Bombay]]. 3 additional ''Godavari''-class frigates were to be built at [[Garden Reach Shipbuilders and Engineers]] (GRSE) in [[Calcutta]]. After a transfer of technology from MDL to GRSE, production was to start in 1988, with deliveries between 1993 and 1996.
