Otto Kretschmer was the most successful U-boat commander of the Second World War. While his wartime actions have been narrated several times, his tactics, summarized by the famous motto ‘one torpedo, one ship’, have never been systematically analysed. In this work, Kretschmer’s success is appraised through the analysis of the key characteristics of his attacks, and the conditions of the battlefield in which he operated. In doing so, both the effectiveness and limitations of Kretschmer’s tactics are clarified and put into the context of the Battle of the Atlantic.

“一枚鱼雷，一艘船”：对奥托·克雷奇默（Otto Kretschmer）的U艇战术的评估，1939年-1941年

奥托·克雷奇默（Otto Kretschmer）是第二次世界大战中最成功的U型船指挥官。尽管对他的战时行动进行了数次叙述，但他的战术以著名的座右铭“一枚鱼雷，一艘船”来概括，却从未得到过系统的分析。在这项工作中，克里特施默尔的成功是通过分析其攻击的主要特征以及他所从事的战场条件来评估的。通过这样做，阐明了克雷奇默策略的有效性和局限性，并将其纳入了大西洋之战的背景。
