Due to the threat of American submarines and aircraft carriers and worsening fuel shortages, both "Yamato" and "Musashi" spent the majority of their careers in naval bases at Brunei, Truk, and Kure—deploying on several occasions in response to American raids on Japanese bases—before participating in the Battle of Leyte Gulf in October 1944, as part of Vice Admiral Kurita's Center Force. "Musashi" was sunk during the battle by American airplanes. "Shinano" was sunk ten days after her commissioning in November 1944 by the American submarine while "Yamato" was sunk by US carrier aircraft in April 1945 during Operation Ten-Go.
