What value did helicopter cruisers such as Moskva and the through-deck cruisers provide?
Short answerThey made sense when ASW helicopters had to be concentrated, but became less distinctive as aviation was distributed across more escorts.
NotesEarly helicopter cruisers answer a genuine anti-submarine requirement by putting a large rotary-wing group at sea. That concentration is especially valuable when few other ships can operate useful numbers of helicopters. As aviation facilities spread across the fleet, the same ASW effort becomes less dependent on a single specialised hull. The design's usefulness therefore changes with the wider fleet architecture rather than with the cruiser alone.
