@Penguin do you still think that the IN needs the RBU-600s to provide the "hard kill" option for incoming torpedoes? I'm pretty sure those systems will remain on the majority of frontline IN warships for the foreseeable future (even though some will parrot their use for ASuW also which has always been very dubious to me) but they are perhaps surplus to requirements and an eyesore to boot.
Anyway, the IN is taking ASW very seriously, they are investing in a multitude of complimentary ASW systems (HUMSA NG, ACTAS, P-8I, S-70B- both armed with the Mk 54- P-28 Kaveri ASW corvettes). All top-notch hardware and simply unparalleled in the region.
