Operation Rising Sun: The sinking of Japan’s secret submarine ‘I-52’

摘要

I-52 was to take part in the so-called Yanagi missions which aimed to exchange materials, technology and personnel between Japan and Germany. In all, some five missions were undertaken during the Second World War. Three arrived safely, with two submarines sunk en route. Of the three successful outbound vessels only one completed her return voyage, with two sunk before reaching Japan.
