The aircraft range values appear inconsistent.
F-15 and F-16 seem calculated with external fuel tanks, while Su-27/Su-33 appear based on internal fuel only.
Since the displayed value represents internal endurance, ranges should be normalized using internal fuel capacity only to keep aircraft balance realistic.
Logically speaking, the ranges should be something like this :
F-15C 292 km
Su-27 270–300 km
Su-33 240–270 km
F-16 150–180 km
