Mogami also had collided with her sister Mikuma during the Battle of Midway in 1942. She bent her bow in the collision, but Mikuma's oil tanks were ruptured, leaving a trail for USN Dauntlesses to follow - in the subsequent attacks on 6 June, both ships were bombed. Mikuma did not survive her damage, especially when her torpedoes were touched off, and she sank.
