On November 20, 1943, the United States launched Operation Galvanic, targeting the Japanese-held Gilbert Islands in the Pacific. A pivotal component of this operation was the Battle of Tarawa, where U.S. forces aimed to capture Betio Island within the Tarawa Atoll. This marked the first major amphibious assault in the central Pacific, confronting well-fortified Japanese defenses. The invasion was supported by a formidable array of aircraft, including 11 fleet and light aircraft carriers, eight escort carriers, and land-based planes from the U.S. Navy and the Army Air Forces’ Seventh Air Force. These air units provided crucial support, conducting pre-landing bombardments and offering close air support to ground troops. Despite the Japanese having only 46 aircraft in the Gilbert and Marshall Islands combined, they managed to damage the USS Independence (CVL-22) with a torpedo, though at the cost of eight of their own planes. After 76 hours of intense combat, U.S. forces secured Betio Island. The battle resulted in significant casualties on both sides but demonstrated the effectiveness of coordinated amphibious and aerial operations. The success at Tarawa also provided valuable lessons for subsequent Pacific campaigns.
