...You mean no one though to fire anything at the drill while it was drilling a hole in the planet's surface. Even if we figure out thatthat the Vulcans either had no weapons or were not sure to fire on the drill, once it starts hitting Earth they should have been shooting all sorts of stuff to try to destroy it.
That, and the fact that the guy destroys Vulcan, Spock and Kirk are arguing over where to go and what to do, but no one checked out where Nero was headed and figured he might try to do the same thing once he got there?
I think Nero kind of tells Pike that he will not only SAVE ROMULUS but will ensure that it lives free of the Federation (I am pretty sure he planned to take care of the Klingons as well). So he probably would have saved Romulus, but first things first, Revenge.
Im pretty sure any ships that were in a position to attack the drill were easily destroyed by the Narada before they could get close.
When Spock was manuevering to ram Nero's ship, they "fired everything" at him. That amounted to what, a dozen torpedos? When the Federation fleet arrived in Vulcan, they should have had at least one or two shots at the "barbed wire"above the drill platform. Given that the Enterprise herself took out all of the "fire everything" torpedos, it's non-sensical that a fleet couldn't get a shot into that platform or the cables holding it up.
or Nero had hundreds of torpedoes when the fleet arrived but by the end of the battle he was left with a couple of dozen.
Besides, the Federation ships were probably trying to damage crucial systems of the Narada while getting their asses severely kicked by its surprise attack.Bridge, engines, weapons.
I somehow doubt their firing priorities while under heavy damage would include some drilling platform, especially since they didn't know anything about Red matter or a black hole sucking the planet evil plan
