LFASCU-1 went ashore at Iwo Jima on 24 February 1944 establishing their position a half a mile from the base of Mount Suribachi. On 1 March 1945 at 1000 LFASCU-1 assumed control of close air support missions. This marked the first time that the United States Navy had officially delegated this authority ashore during an amphibious operation. LFASCU-1 operated on Iwo Jima until 11 March 1945 when they were pulled out in order to begin preparations for follow on operations.
