在第二次世界大战的太平洋战争中,日军共有60多艘特种潜艇被投入到中途岛、基斯卡岛、腊包尔、特鲁克群岛、比岛(菲律宾)、冲绳、父岛等地区。它们通过货船拖运、搭载母舰或运输舰以及自行的方式前往预定作战区域,但是因为在中途遭遇袭击、恶劣天气或变更作战部署等原因,只有大约四成的特种潜艇历尽艰辛,最终抵达了目的地。在抵达目的地后,由于缺少有力的后方支援及指挥失误,结果只有8艘特种潜艇向盟军舰队发射了鱼雷,只摧毁了1艘盟军驱逐舰,这是得到确认的唯一战果。后来,在抵抗美军登陆日本本土的作战中,日军特种潜艇部队伤亡巨大,最终全军覆没。总的来看,与他们无与伦比的“忠诚”相比,所得到的回报几乎等于零。 During the war in the Second World War in the Pacific, a total of more than 60 Japanese special submarines were deployed to Midway, Keyca, Rabaul, Truk Islands, Bhikkhu (Philippines), Okinawa, . They are towed by cargo ships, loaded with mothership or carrier ships and made their way to the intended areas of combat. However, only about 40% of the special submarines have finally reached their goal because of attacks on mid-way, inclement weather or changing deployment. Ground After arriving at the destination, only eight special submarines fired torpedoes on the Allied fleet and destroyed only one Allied destroyer in the absence of strong rear support and commanding mistakes. This was the only confirmed outcome. Later, in fighting the U.S. military’s landing in Japan, the Japanese special submarine force suffered heavy casualties and eventually wiped out the army. On the whole, the returns they receive are almost equal to zero compared to their unparalleled “loyalty.”
