Personally, I think China needs VTOL aircraft. With the rise of China, China's real rival is no longer any other country, but the United States, the world's first military power. In order to be able to cope with the attack of the US Air Force, any military base, port, fleet and local important places in China must have sufficient emergency air defense capabilities to buy time for the take-off and counterattack of the main air defense fleet. Air defense missiles are inherently inferior to air-to-air weapons because they take off from the ground or the sea, so vertical take-off and landing aircraft is the best emergency air defense weapon.
