To avoid taking the Su-57 thread off topic, and to set the record straight by providing data straight from McDonnell Douglas themselves, here's some actual max ITR data for F-15C, unless @PeregrineFalcon has information to prove that they are wrong about their own aircraft.
And for the record, on the F-15 the AOA[units]=AOA[degrees] + 11.
This is to show that first of all, 40 degrees AOA is actually usable, and F-15 can reach those AOAs well under 700km/h that's been thrown around here.
And also, same user claimed that F-15C has range on internal fuel of 2,067km by simply taking the percentage of internal fuel to max fuel with 3 EFTs, 53%, and multiplying with the ferry range with 3 EFTs, which completely ignores the additional drag from the 3 EFTs which has DI=23.2 and the higher fuel flow from the higher weight. One can easily see that DI=20 causes over 10% more fuel flow at 480 knots.
So in actuality, even pessimistically assuming that F-15C uses 3,455lbs of fuel for takeoff, climb, and landing, still can cruise over 2,300km at 480 knots with 10,000lbs of internal fuel remaining.
