The STS or
Sen-Taka-Sho were
small coastal defense submarines that were optimized for underwater
speed and equipped with a snorkel, making them "true" submarines. They
were a good design for their intended role and were relatively simple
to construct. In practice, their endurance was considerably greater
than the design figure, as was their maximum safe dive depth, estimated
by Japanese naval architects as 500 feet (150 meters). Although 90
units were planned, few were completed before the war ended. We
list here only those that were completed before the surrender.
