I-15 was a Japanese B1 type submarine. She was completed at Kure Navy Yard on September 30, 1940, whereupon she entered into service with the Imperial Japanese Navy. Her first and only commanding officer was Commander Nobuo Ishikawa. I-15 operated off the north coast of Oahu during the raid on Pearl Harbor. Her second wartime patrol, in May and June 1942, took her to the Aleutians, where she conducted reconnaissance of several islands. I-15's third and final patrol took place from August to November 1942, when she operated in the Solomon Islands in the South Pacific, supporting the Japanese efforts to hold Guadalcanal. One source (Morison) suggests that I-15 hit the battleship USS North Carolina with a torpedo on September 15, 1942, but more recent authorities (Hackett & Kingsepp) maintain that the torpedo came from another submarine operating in the area, I-19. On November 10, 1942, a U.S. ex-destroyer (modified to a fast minesweeper), USS Southard (DMS-10) sank I-15 in Cape Rechereche, San Cristobal, with all hands lost.[2] Commander Ishikawa was promoted to the rank of Captain posthumously.
