I flew F-4’s out of Andrews in ’76 just as the 1st TFW was getting the brand new F-15A. We got to fight them in dissimilar ACM. The performance of the F-15 was eye watering. They were significantly superior to the F-4 in every area, particularly if the F-4 got below 400 kts. My technique for fighting them was to stay between 500 and 600 kts. Everyone turns the same at 6 g. at 500 kts. That was where I minimized my disadvantages.
