Modifications
Many of these units were converted to fast transports in 1941-1942, with armament of 2 4.7" guns, 10 25mm/60 AA guns, and their torpedoes.
1944-6: Remaining units had light AA armament of 10 25mm and 5 13mm/76 AA guns.


The Mutsukis were completed in 1925-1927, primarily in naval yards. They were the first Japanese destroyers completed with tubes for 24" (61 cm) torpedoes. They were also the first destroyers with triple tubes, which reduced the number of mountings without loss of firepower. In most other respects they resembled the Kamikazes.

They were a disappointment to the Japanese, falling short of their design speed and proving flimsy in combat. As a result, most were converted to fast transports early in the war. No ship of this class ever survived a solid hit by a bomb or torpedo, and none survived the war.

It is an indication of how badly the Japanese underestimated the Wake defenses that the Wake Invasion Force escort was built around ships of this type.
