why would it be operating UAVs? like we said, it's helipad is the same as one 053h2 class. That helipad was purposefully made big enough to operate proper helicopters.
It is all about the mission profile. If the 056 goes out 500-1000 km away from chinese shores, it probably won't be operating helicopters. But I don't think that is a mission 056 will often, if ever do. I think it was designed to go a few hundred km away from chinese shores. It isn't meant to support a helicopter past refuelling and rearming. I imagine helicopters, in those missions where they are required, would fly to the 056 from the shore, would then temporarely base itself on the ship for x days, operate from it as needed, then return to the shore, at which point, if needed, another helicopter might replace it. Yes, that might mean that at certain times, due to extreme weather and sea states, helicopters would have to leave prematurely. But it is still an added capability.
