The SS or Sen-Yu-Sho were
small supply submarines of
simple construction and limited endurance
designed to deliver vital supplies to isolated garrisons. They were built in response to heavy losses of the larger D2 type. Their modular
design, with all-welded construction, allowed a unit to be completed in
as little as five months. They had a
primitive anechoic coating applied to their conning towers, and some units were equipped with snorkels. However,
they proved unable to deliver enough supplies to vitiate the Allied island hopping strategy. All were surrendered
to the Allies at the end of
the war, and most were scuttled by the Americans within a year.
An additional two units were not completed, and another 88 units were ordered but never laid down.
