Actually I take it back I don’t like your metaphor. It would be accurate if the industrial and technical requirements between 5th and 6th gen aircraft were as different as that of a horse and buggy, but fundamentally that’s not the case.
Both call for stealth technology, advanced integrated avionics, high performance gas turbines, composite material and titanium structures to meet strength/weight requirements, and advanced radar/sensors, all combined in a package that is both reliable and can be manufactured em mass.
The US has been demonstrating those capabilities for 30 years. China has obtained some of them (still lags in engine, avionics capabilities, and radar) and has only been able to manufacture aircraft with them at a fraction of the scale.
The Chinese aircraft industry is suddenly going to leapfrog the US on all of those features AND manufacture them on a great scale? I doubt that.
Is this fucking loss
