I was in Central America when the “Moskva” visited and was able to talk with one of its senior officers.
Their “culture of maintenance” stinks beyond anything we could even imagine and the ship was barely able to keep moving for it’s port visits.
Any weapon system used by the Russians will need some major tinkering to get it to work correctly, if reliably.
And knowing how they “weigh” their testing, the Indians must think they can do something with the tech. not necessarily the actual system.
In the early 90s, a Kynda and Kara class cruisers stopped at the Norfolk Naval Station. Got a chance to tour both ships. They were disasters waiting to happen. Soviet naval architects have zero concept of water tight integrity. I didn’t see one complete watertight bulkhead on either ship. Cables passing through were not in stuffing tubes. Openings between decks without hatches. Door ways through bulkheads with out water tight doors. Never did see anything akin to repair locker. No emergency power distribution system, didn’t see any fire main or hose connections. If you dodged the missiles, a 2250 class tin can could have easily sent either of these ships to the bottom with their 5 inch guns. Guess the Soviet Navy philosophy was stay afloat just long enough to launch you main missiles and we will see the Captain gets his Hero of the Soviet Union medal presented to his widow.
