Although Chitose was speculated to carry Type A midget submarines, she underwent conversion to a light aircraft carrier at Sasebo Navy Yard in 1943, and was recommissioned on Nov. 1, 1943, and saw several naval actions. She was sunk by a combination of naval bombers during the Battle of Leyte Gulf.
