Ken,
A generation before the Tornado ADV The US was producing the F-4, F-5, F-8, F-101, F-104, F-105, F-106. Other successful fighters of the time to consider - Mirage 3 and Mig 21. How do they compare with the Tornado ADV after the merge? I imagine the F-8 and F-106 might have low wing loadings but not enough puff? Mig 21 would be an interesting. But on the whole Tornado would pretty agile compared to fighters of the time.
Now lets compare the 80's benchmark F-15 with today machines after the merge? How would the Eagle go against F-22, Su-30MKi, Typhoon ?
Perhaps you will agree there is a correlation between time and increased agility?
Now what were you leading to with respect to the F-35?
