Background
Gorō Maru in 1939
- October 1938, the IJA succeeded the amphibious operations for Bias Bay with Shinshū Maru. However, long time needed for the operations, because they used low speed landing craft. Therefore, the damage was big, too.
- The IJA thought about amphibious warfare for "small damage" and "quick action".
- In 1939-1940, the IJA repeated an experiment with Gorō Maru (300 tons gross) and Yorihime Maru (526 tons gross). And they analyzed experiment data and placed an order for prototype Kōryū (later SS No.1).
- The IJN was interested in second prototype Banryū (later SS No.2). As for the IJN, 16 ships placed an order, However, they adopted No.101-class, the ordering was canceled.
