By than 002 would be the primary carrier for the PLAN with catapult launching capabilities. There would be no more building of the type 001 or 001A unless Pakistan, Russia, or someone else wants one to be build to spec.
The 001 & 001A should have a service life of roughly 50 years (the US carriers served even longer than that), which would necessitate a complete rehaul of her airwing some time between now and then. Even if no more 001/001A are built, the current vessels would need a next-generation fighter to replace her J-15s.
