The Asashios were completed in 1937-39. They were loosely based on the Shiratsuyu class. As the first post-treaty Japanese destroyers, they predictably did not lack for firepower or strength. However, they had persistent engine and steering bugs. The rudder design was inefficient, yielding poor maneuverability, whicih was remedied in 1941 by altering the stern shape. The turbines pushed the limits of Japanese technology and were prone to blade stripping, and the root cause of this defect was not identified and corrected until 1943. Their cruising range was also unusually poor.
