I seem to remember reading something similar about the -30s vs the F-15 C about a year or so back? Although it was the old (non-aesa) radar, the f-22 mafia were monking about the -Cs getting trashed... disaster, loss of air supremacy etc etc etc. A little further digging revealed that the worry was the F-15s had a kill/loss ratio of only 3:1 rather than the 5:1 or 6:1 they'd been expecting.... oh the horror...
