Mark 31 torpedo
http://dbpedia.org/resource/Mark_31_torpedo an entity of type: Thing
The Mark 31 torpedo was a destroyer-launched acoustic torpedo developed by the Harvard and Pennsylvania State universities during World War II. A modification of the Mark 18 electric torpedo, it was conceived as an interim weapon to be used in the Pacific War until a new high-speed acoustic torpedo could be developed for the United States Navy. Further development of the torpedo was terminated due to the status of other more promising programs, notably the Mark 16 torpedo and the Mark 35 torpedo.

Mk 31型魚雷是一種於驅逐艦上發射的聲波制導魚雷，由哈佛大學和賓夕法尼亞州立大學於二戰期間研發。作為Mk 18型電力推進魚雷的修改版，被視為是太平洋戰爭上的一種暫時過渡性武器，直至有供美國海軍用的新型高速聲波制導魚雷被研發出來。 Mk 31因其它成功率更高的項目的狀態，特別是Mk 16型魚雷和Mk 35型魚雷，Mk 31型魚雷的進一步研發被終止。
