However, the two Indian shipyards had stood firm on their stand that all the frigates could be manufactured indigenously and there was no need to outsource even one of the warships. One argument put forward was that it would not be wise to manufacture the ship abroad as it incorporated advanced indigenously developed stealth features.

With the Defence Ministry taking the final call on the matter, the frigates will be manufactured in India and are expected to be inducted by 2021. The project is expected to start by 2011 when both GRSE and MDL complete an upgrade that will allow them to undertake modular construction. The first ship is expected to be delivered 3-4 years after work starts.
