If you want a on hit sink, then the torpedo would be the choice. The dive bomber was expected to hit the target over and over again and the torpedo planes were icing on the cake. The bombs that were used could only sink the ship in one hit if a magazine or boiler was hit. But against a carrier bombs blow up the deck and can make it usless not to mention the lack of armor here as compared to a battleship. Special bombs were developed for the divebombers I believe.

If you want a hit and not a kill go with the dive bombers, get five or six hits and you will probably sink the ship.
