The Porpoises
were minelaying submarines built in 1931-1937. They used a simple and
effective minelaying systems in which mines were stored in a rail on
top of the pressure hull and winched through a hatch in the stern.
However, the final three units were canceled when a mine suitable for
deployment through the torpedo tubes of regular submarines was
developed.
