If there is any truth to recent news stories about France offering Suffren SSN tech to India, a Batch 2 Kalavari program may well become a conduit for ToT and related budget allocation.
Plus the IN is interested in a new sub launched LACM for which a RfI is currently out. More than likely, we'll end up with the Scalp Naval to equip both the Type 214I and Kalvari classes.
TLAM is a non starter for political reasons and Kalibr won't be available/compatible for integration on Western-origin boats.
So we may yet see an order for B2 Kalvari going through, imo.
