Bastion
Some more thoughts on how the Chinese might use their two carriers in an operational role:
The design concept for the first Soviet aircraft carriers differed considerably from that of their U.S. Navy counterparts. Instead of supporting expeditionary operations, or carrying out strikes against high value targets, Soviet carriers were designed to deter or defeat Western forays into protected bastions for ballistic missile submarines. This included flying air defense against U.S. anti-submarine warfare aircraft (whether carrier or land-based), as well as having the capability of destroying invading U.S. surface ships and submarines (through SSMs and ASW helicopters). The VSTOL Kievs and the STOBAR Kuznetsovs could only launch short-range fighters, but this was all they needed in order to maintain a defensive perimeter.
