Background
- Project number I4. Improved model of the No.13-class. They were built to update timeworn No.7-class, No.9-class and No.11-class.[1] Kampon deleted minelayer facility from them, because IJN hoped they act in Yangtze River. And they added to 1 × 120 mm naval gun for engage with National Revolutionary Army. Therefore, No.7-class had the silhouette which resembled torpedo boat Chidori-class and Ōtori-class well.
