Rumor was CIWS wasn’t working on the Moskva. Also some of radars interfered with each other so they kept some of them off. That was inferred off of pictures from the sinking and the radar used to detect sea skimming threats was in the stow position. There is also more countermeasures than ciws. Warships also can deploy decoys and chaff to confuse radar homing missiles.
