3. If a projectile the size of a football would have the power of several nukes, wouldn’t the power still only be directed mostly forwards (and not in all directions like a bomb)? I assume a small projectile would only punch a hole straight through like a bullet rather than “nuking” the target. That wouldn’t necessarily work on something like the Death Star.
Only if the projectile would somehow magically be able to remain intact. However, given the amount of energy involved the projectile would disintegrate as would the Death Star at the point of impact, resulting in flying debris with a similar amount of energy as the projectile, which would wreak havoc on the station and anything in the vicinity.
