Considering that the US would be launching their offensive off of their aircraft carriers, the F-15's would be much riskier in a combat situation since US ME air bases are within missile range. The dual would come from the American Super Hornet and the main Iranian F-14's still in service that guard the vital infrastructure. The F-14 is an air superiority fighter armed with the existing AIM-54 Phoenix AA missiles the Iranians still have, which outmatch anything the F-14 carries. Iran would also have the viability advantage since ground radars can transmit data to the pilot. Which one would win?
