The only use for turbojet engines are in OLD military and commercial aircraft. Modern military planes use turbofans just as commercial ones do - it's the bypass ratio that accounts for the variation in efficiency (i.e. it is more efficient to move a large ammount of air slow than a little ammount of air fast). It's all F=ma.... the more "m", the less "a" the better off you are.
