What was a decisive naval battle in the Pacifix Theater of WW2 that "Zuihō" played a secondary role in?
Battle of Midway The Battle of Midway was a decisive naval battle in the Pacific Theater of World War II which occurred between 4 and 7 June 1942, only six months after Japan's attack on Pearl Harbor and one month after the Battle of the Coral Sea. The United States Navy under Admirals Chester Nimitz, Frank Jack Fletcher, and Raymond A. Spruance defeated an attacking fleet of the Imperial Japanese Navy under Admirals Isoroku Yamamoto, Chuichi Nagumo, and Nobutake Kondo near Midway Atoll, inflicting devastating damage on the Japanese fleet that proved irreparable. Military historian John Keegan called it "the most stunning and decisive blow in the history of naval warfare."
Japanese submarine I-401 The "Sen Toku"-class I-401 (伊号第四百一潜水艦 ) was once the largest submarine in the world. It was commanded by Lieutenant Commander Nobukiyo Nambu of the Imperial Japanese Navy during World War II. Capable of carrying three two-seat Aichi M6A1 "Seiran" (Mountain Haze) float torpedo bombers, the "Sen Toku"s were built to launch a surprise air strike against the Panama Canal.
