In late June, "North Carolina" was one of the American ships which took part in the so-called "Marianas Turkey Shoot", where a majority of attacking Japanese aircraft were shot down out of the air at little cost to the American defenders. Problems with its propeller shafts then caused the battleship to sail to the Puget Sound Navy Yard to receive an overhaul. It returned to active duty in November and to its carrier escort tasks in time to be hit by a typhoon. "North Carolina" protected carriers while they provided air cover for invasion fleets and launched attacks on Leyte, Luzon, and the Visayas. Surviving another typhoon, one which sank three destroyers, "North Carolina" continued escort duty when naval aircraft struck Formosa, Indo-China, China, the Ryukyus and Honshu in January and February 1945. During the invasion of Iwo Jima, the battleship provided bombardment support for troops ashore.
