It is probably more about range be it subsonic or supersonic.


If it does not have afterburner section on engines then those are lighter thus perhaps 25 percent less gross weight than those that have it. Often heavily loaded fighter jets use afterburner to have shorter take off distance, but that is very inefficient as it can consume 2.5 times more fuel per generated thrust kilogram for kilogram while actual fuel consumption when taking account increased thrust is 4 times greater per second. Take off with afterburner active for at least a minute could consume amount of fuel that is equivalent in weight of a jet engine.



Issue is not amount of engines as is position of those.


This CAC 6th generation aircraft is being efficient in placement of such.
