Abukuma was a Nagara-class light cruiser of the Imperial Japanese Navy. In December 1941 she was flagship of Destroyer Squadron 1 with the striking force that went to Pearl Harbor.
On 7 December 1941 she flew that flag over the destroyer squadron screening the carriers. The attack left her unhit.
On 25 October 1944 she entered the Battle of Surigao Strait. A torpedo struck her on the way in, damaged her, and she fell out of the column.
The torpedo came from the boat PT-137. Lieutenant (junior grade) Isadore Michael Kovar fired at a destroyer and could not see the cruiser when he fired. The torpedo ran on and hit Abukuma.
Army bombers sank her the next day off Negros. PT-137 had damaged her; the bombers sank the ship the following day. That sinking is not credited to one ship.
