The Wasp damage report (posted previously) suspects that only two torpedoes struck her.
According to USNI Proceedings, it was indeed three:
The Wasp had just taken in planes and all her gasoline lines were running when at 1442 she reached a position only 500 yards from I-19. The submarine fired four torpedoes, three of which hit the carrier in almost the same place, on the starboard side forward.
Note that if they're wrong and you're right, that only reinforces my point about torpedo vulnerability.
