アッツ島沖海戦
"Abukuma" participated in the Battle of the Komandorski Islands on 26 March 1943, during which time she fired 95 rounds from her 140mm guns and four torpedoes. "Abukuma" was undamaged during the battle, but the heavy cruiser was badly damaged and the Japanese Fifth Fleet was forced to abort its supply mission to the Aleutians. The fleet commander, Vice Admiral Hosogaya, disgraced because he had been forced to withdraw by the weaker American fleet, was forced to retire.
