Accordingly, the Japanese submarine arm had few notable successes against Allied warships during the final two years of the war. One victory was the knocking the anti-aircraft cruiser out for the rest of the war with a torpedo hit on November 3, 1944 (this was the first time in almost two years that a Japanese submarine had successfully attacked an Allied ship operating with a fast carrier task force). A more famous incident was the torpedoing and sinking heavy cruiser , with heavy loss of life. The sinking occurred on July 30, 1945, just two weeks before the Japanese surrender, at a time when few in the United States Navy expected continued Japanese submarine attacks.
