>>That’s assuming the aircraft are not superior aircraft.
The F-35A is an outstanding strike fighter and the STOVAL F-35B is a breakthrough aircraft technology that so outclasses the AV-8B it replaces that there is no comparison.
The jury is still out on the F-35C Navy variant but it should be much better than the F-18 it replaces. <<
I hope your grandkids appreciate it.
The United States Marine Corps has done an outstanding job with the Harrier despite its many handicaps and serious deficiencies. I’m sure they will manage to do the same with the much more expensive and equally capable F-35 somehow.
