I have been wondering about the potential utility of light ASW Helicopter Carriers for China going forward.
In the long-term, ASW will have to become a top priority for the Chinese Navy in order to ensure continued access to SCS in the face of possible blockade attempts by nations operating large numbers of advanced submarines.
The first question is whether a dedicated ASW platform in the vein of the Japanese Hyuga/Izumo types, or the Soviet Moskva type, makes sense in this environment, or whether their tasks can be performed almost as well from aircraft carrier and LHD platforms, plus traditional escorts. Or could we see something in between, such as an 055-type hull with extended aviation facilities, akin to the Spruance-derived concepts that the US looked at?
The second question, if a dedicated carrier-type like the Japanese Hyuga/Izumo designs is seen as the way forward, how far do you go with such a design? For example, you could add a single EM cat and arrestor gear to facilitate the operation of UAVs themselves operating in a surveillance/ASW role. And if you go that far, you could size the vessel such that it could serve as an emergency "second deck" for carrier-based aircraft, e.g. able to recover e.g. a J-15 with no payload, and preferably to launch it again with 50% fuel and no payload. You would have a whole range of options ranging from a Hyuga-type vessel to a 40,000 ton light carrier.
