As per the deal, two ships are to be built in Russia, while the other two to be built at the Goa Shipyard in India with technical collaboration from Russia. The first of the two frigates will be delivered to Indian Navy by 2022-end, while the second vessel is scheduled to be delivered six months later in 2023.
