Zhao Yi ignored Liu Jiankun's reaction and continued with his thought process. He wasn't considering installing an anti-gravity propulsion device on an airplane but rather contemplating takeoff on an anti-gravity device.
The former would not be easy to achieve—it would essentially be the development of an anti-gravity aircraft.
The latter had to be considered.
Warhawk aircraft might be used as carrier-based aircraft in the future. Even if they weren't, once anti-gravity technology developed, it would certainly take into account takeoffs and landings on anti-gravity devices, and airplane design would definitely need to be modified; otherwise, it would be phased out by technology.
Putting that aside for the moment, he went on thinking and thought about the application of anti-gravity on aircraft carriers.
