To be honest, i don't understand some of the violent opposition to VTOL planes i see here. They are obviously serving a specific niche, have been doing so for decades and will do so for many more to come in numerous world navies. Their advantages have been stated quite well by that PLA paper, so i won't go there much, but just to go over again WHERE could they best serve.
First, on the at least 6 075s and whatever number of 076 will be built, though there is still a possibility 076 might use CTOL planes. In a pinch, you can probably fly a couple from the 071s too.
Then, in times of need/hostilities, ro-ro and similar merchants could be converted to operate a few VTOL fighters. China is now the economic and building engine of the world, if someone could pull that off is China.
Needles to say, the capability to fly from small islands and random clearings outside normal airbases, that COULD be incapacitated in a conflict.
Yes, there is a downside to VTOL planes, the need for reduced payload, range or performance in whichever mix, BUT they will still bring to the game the same advanced electronics and weapons as CTOL planes, that otherwise will not be possible to with conventional planes.
Do not forget, the US lackeys Japan, ROK and Australia have another 8 LHDs to add to the US ones, despite what the official statements say, does anyone doubt that in case of conflict with China those will not be flying as many F-35Bs/Harriers as they can stuff in, either american or their own?
So yeah, i can only agree with that PLA paper, within PLAN's aspirations of a world class navy VTOL planes are a necessity.
