[Machine Translation] In August 1942, Commander-in-Chief of the Combined Fleet Isoroku Yamamoto decided to organize an epoch-making new fleet to break the deadlock in the war. It was a submarine task force consisting of a huge submarine carrier, the I-400, equipped with the Hararashi surface attack aircraft. In January of the following year, the newly organized task force secretly set sail. A major counteroffensive began in the Central Pacific, destroying trade between the U.S. and Australia and recapturing Guadalcanal. The U.S. Navy countered with massed maneuvers, and the submarine task force was temporarily threatened. However, the submarine task force counterattacked with ultra-long-range oxygen torpedo attacks and new anti-destroyer weapons, and also deployed the high-speed submarine I 201 to escort the submarine carriers. The Japanese Navy, which planned to use the capture of Hawaii as a foothold for early peace, and the U.S. Navy, which was determined to win a decisive battle, clashed off the coast of Hawaii.

1942年8月、山本五十六連合艦隊司令長官は、敗色濃厚となった戦局を打開すべく、画期的な新艦隊の編成を決意した。それは巨大潜水空母伊四〇〇型に水上攻撃機晴嵐を搭載した海底機動艦隊だった。翌年1月、新編成なった機動艦隊は秘かに出撃。米豪間の通商破壊、ガダルカナル再奪還と中部太平洋方面での大反攻が始まったのだ。米海軍は物量作戦でこれに対抗、一時は海底機動艦隊にも危機が迫る。だが、海底機動艦隊は酸素魚雷超遠距離雷撃、対駆逐艦攻撃用新兵器で反撃、さらに潜水空母を護衛する水中高速潜伊二〇一型も投入し、万全の態勢を整えた。ハワイ占領を足がかりに早期講和を目論む日本海軍と乾坤一擲の決戦に臨む米海軍が、ハワイ沖で激突する。
