Project history: Design of Matsu class ships has been created, first of all, for replenishment of losses suffered by the IJN during battles at Solomons. Having generalised experience of the last campaign, the Naval Staff has reconsidered requests to destroyers, having outlined a new subclass of fast squadron ship (Kihon Keikaku Bango). These ships did not intend for operations with squadrons, that allowed to simplify and reduce the price of building and to build them in bigger numbers and quickly enough. The technical design provided standard displacement 1250t, 28kts speed and an endurance 3500nm under 18kts speed. The armament intended, basically, for solving of AAW and ASW tasks. Special attention was given to measures on building acceleration to what electric welding was widely applied. For the first time on Japanese destroyers machinery was placed en echelon, that raised general damage tolerance. Unlike 127mm/50 guns in turrets, standard for previous destroyer classes, on Matsu there were dual-purpose 127mms/40 guns in single and twin deck mounts, much more adapted for antiaircraft fire. Though ships also did not intend for squadron battles, they carried torpedo armament, and it was originally supposed to equip them with sextuple 610mm TTs. As creation of these devices was delayed, standard quadruple 610mm TTs were installed.
In total under the additional programme of 1942 it was planned to built 29 ships of this class, however the order on 11 destroyers was subsequently cancelled.
