"You mean they could have just used a small hyperspace ship to destroy the Death Star? You mean a single HyperSpace capable X-wing could have destroyed the Death Star? "
If a hyperspace capable ship is able to blow apart massive star ships, they they would build small ones and call them "hyperspace torpedoes".
Only one needs to hit squarely, but you need a few squads to deflect the CAP and AA.
