Too bad they weren't fitted with the engines from the F-111F...
GK121, u r so right.
We evidently had the option, in the day (1969-71, I believe) because of the delivery delays, to change our F-111C order to the F-111F.
Unfortunately, due to Govt bureaucracy (and possibly for fear of further price increases), this was not taken up.
Big shame. We could have avoided our orphan AUP (based largely on F-111A/E AMP) and run with the F-111F Pacer Strike upgrade in 1995. 25k of poke per side, and the aircraft could easily have pressed on beyond 2010 (our withdrawal date). BTW, I think F-111F airtests went to M2.5.
