This Museum exhibit displays The Battle of Midway, which is frequently referred to as "the turning point in the Pacific." In June 1942, the Japanese had hoped to surprise the American military on Midway Island and claim this crucial location. However, American Navy cryptologists stationed in Hawaii had made some breaks into the Japanese Navy Fleet Code, known to cryptanalysts as JN-25B. Knowing Midway would be attacked, the U.S. Navy and Marines were able to adjust their forces and combat the attack head on. After a series of losses, the United States won a decisive victory over the Japanese Imperial fleet. Damages to the Japanese carrier fleet were insurmountable and their momentum was broken. The Japanese were never able to replace the four aircraft carriers and 332 aircraft they lost in the battle.
