funny. when you have gun, you already lost 1 missile or 2. Gun is heavy, occupy a big chunk of space.
Any space and weight is precious, you have to balance your options, and think how to take the maximum usage of those space and weight.
Everything comes a cost. You carry a gun, lose space and weight for more air to air missiles in the first place.
F-35 can not do super cruise for good reasons. Bulky body, very limited space for weapon bay.
I stop here, mod

It seems you are quite new to jet design.
