Sounds like good value for money if four F-35s can do the work of 12 or 13 aircraft of the previous generation:
The good general's "previous generation" comprises clapped-out Classic Hornets and Harriers with warmed-over 1970s radar, superheterodyne/analog RWR and either no ECM or a bit of wheezy 1980s stuff. So the statement is not as exciting as enthusiasts might like.
