Personally, these shots with Fuel tanks on fighter aircraft - to me, just don't say the right thing about fighter aircraft - Fighter - Jangandah - Shikari - armed to the teeth, not one that needs to carry it's fuel it's fuel externally
Unfortunately, these Shikaris have extremely high metabolisms and need to drink a lot.
To be able to carry enough fuel internally and still be deadly you need to be big, dedicated air to air killers like the F-15 and Su-27 are just that.
