They are still working on the catapults. it is years away from service.
Significantly, both the Type 001 and 002 are equipped for short takeoff but arrested recovery, or STOBAR, operations. This involves launching fixed-wing aircraft with the aid of a ‘ski-jump’ ramp on the bow and then recovering them using arrester wires.
The Type 003, however, has no bow ramp and instead marks the PLAN’s switch to catapult-assisted takeoff but arrested recovery, or CATOBAR, operations. While recovery is the same, CATOBAR carriers employ catapults to launch fixed-wing aircraft, allowing them to take off with much heavier fuel and weapons loads. In addition, CATOBAR vessels can support a wider range of aircraft types, including heavier and slower non-fighter designs like the KJ-600 carrier radar plane now in development. Currently, only the United States and France operate carriers of this kind.
This fact make what the Brits did with their two new carrier rather obtuse, going with ramps rather than catapults.
