Chronology Leading up to the Attack
Spring 1940. War Games: For twenty years the goal of the annual IJN fleet exercise had been to defeat the American fleet in the Marshalls as it rushed to rescue the Philippines per US warplan "Orange". The place of air power in the fleet gradually increased. With the movement of the US Pacific fleet to Pearl Harbor, Hawaii, in May 1940, the possibility of moving the Japanese attack line east presented itself.Special armor piercing bombs and shallow running torpedoes required to attack the US fleet at anchor are developed and tested. Fleet units move to Tankan Bay, Kurile Islands, north of Japan, in radio silence.
