1945年1月,日本在输掉了所谓“决定帝国命运”的“阿”号。“捷-1”号作战后,已经无法再和占绝对优势的美军拼杀了。为了保存第4航空军在菲律宾所剩的为数不多的飞行员,日本人决定用他们惯用的伎俩,派潜艇乘夜暗潜行穿过美军的封锁线,到吕宋岛接应他们撤离。但是,这次计划和山本五十六的下场一样,日本人认为绝对可靠的密码再次葬送了他们。 In January 1945, Japan lost the so-called “A ” number that “determines the fate of the empire.” “Czech-1 ” after the battle, it has been unable and the absolute superiority of the U.S. Army to kill. In order to preserve the few remaining pilots of the 4th Air Force in the Philippines, the Japanese decided to use their usual tactics to send submarines to darkness and sneak through the U.S. military cordon and escort them to Luzon. However, like the end of Yamamoto’s 56th plan, the Japanese thought that the absolutely reliable password was ruined again.
