No twin engines are required for deep strike and air superiority ... now realistically speaking is it possible for Pakistan to ever acieve air superiority or deep strike in india which is 5 times larger ? So our war strategy is to keep the deep strike to missiles and airforce prime responsibility is for air defence, air support and to create a buffer zone of few 100 kms from the border ... thunder is a perfect fit in that bill infact it will have an edge over twin seater due to small rcs l, low maintenance and short turn around time ...
