You can apply this to J-36 versus NGAD
Extra engine needs extra fuel, that implies more weight see DC-10 is heavier than A-300, but also see A-300 carries more passengers, so actually a third engine does not bring more passengers and the fuel, seat km does not bring a better aircraft DC-10 carries more fuel for the same range and less passengers.

If the USA makes better engnes means less number of engines and less engines means less fuel, better thermal efficiency means then you need less fuel, less weight and less weight is a more agile fighter
