operation called Magic Magic intercepts allowed Admiral Nimitz to
position two carriers off the eastern tip of New Guinea Both sides
suffered heavy losses but the Japanese were forced to call off
their amphibious attack on Port Moresby Battle waged exclusively
via air strikes Opposing surface ships never made direct contact

- Became the model for Pacific commanders throughout the rest of
the war dont move island to island; advance by great bounds using
air superiority bypass major strongpoints and leave them reduced to
strategic and tactical impotence hit Japanese weak spots; avoid
frontal assaults; use deception and surprise seize existing
airfields and ports and use these newly acquired bases to support
the next leap forward
