Thrawn, anything is possible
I was just wondering what the situation was.
Vulcan, if the ROE of the engagement was setup as a required visual identification before firing, its definitely possible that a well flown A-4 could outfly a F-15. Just as in Vietnam where MiG-17s shotdown F-4's, because the F-4 wasn't allowed to use its standoff capabilities and it got drawn into close in dogfights. Same with the A-4. Its nimble, agile, and quick, and if the F-15 pilots made mistakes they could easily be "killed" in a guns/IR only environment.
