The Enterprise wasn't a hero ship to begin with, it was just a carrier that proved by the end of the war it was a hero ship, thats how most hero ships are born, other are built and over hyped by their goverments, like the yamato, Bismark, Turpiz, ect. Don't get me wrong these weren't JUST hyped ships, they were the biggest and the baddest of ships built, but the Yamato was kept from major battles (battle of the TIN can ships), Bismark was sunk in her first mission, and the Turpiz was never there and was to baddly damaged in dock to do anything and was out of the war. These ships were hyped, the Bismark wasn't suppose to engage any enemys, it was suppose to sink merchant ships, the Yamato kept turning away from battle, till its last battle when they foolishly sent her on a suicide run. After Pearl Harbor they managed to fix a few of those battle ships, they were rarely used for what they were built for though, they were sued for anti surface warefare for landing forces, and they let the carriers take care of anti aircraft, anti ship, and anti land combat. Lots of these hero ships were just used for softening targets. Of course theirs exceptions, like the biggest sea battle ever at Leyte Gulf (I think, I think I'm starting to mix things up)
