Lima Juliet,
"Pretty much every other air force has adopted 2 seat, so is it time for change?"
Er, like who?
F-16, F-35, Typhoon, Gripen, F/A-18, Su-27, Su-30, Su-35 all single seat. Surely the only 2 seat are legacy like F-15E and F/A-18D and a few Rafale anomalies?
I think 1 pilot reducing to 0 pilot is the way rather than 1 to 2...
