CD-47 was a C Type class escort ship (Kaibōkan) of the Imperial Japanese Navy during the Second World War.

History[edit]

She was laid down by Nippon Kokan K.K. (日本鋼管株式會社) at their Tsurumi, Yokohama shipyard on 15 July 1944, launched on 29 September 1944, and completed and commissioned on 2 November 1944.[1][2] She was attached to the Yokosuka Defense Force, Yokosuka Naval District under Lieutenant Commander Fukuji Chiba.[1][2] During the war CD-47 was mostly busy on escort duties mainly to the Ogasawara Islands and the Kurile Islands.[1]

Convoy-Chi[edit]

On 26 May 1945, she departed Paramushiro for Otaru, Hokkaido in convoy-Chi consisting of cargo/transport ships Kuretake Maru, Kasugasan Maru, Tenryo Maru, and supply ship Shirasaki, with Shimushu-class escort ships Shimushu and Hachijo, fellow Type C escort ship CD-205, and Type D escort ship CD-112.[3] Hachijo was lost in the fog around 50°00′N 146°00′E / 50.000°N 146.000°E / 50.000; 146.000 and CD-205 left the convoy to search for her.[3] On 29 May 1945 at 2055, the U.S. submarine USS Sterlet fired two spreads of three torpedoes hitting two of the freighters. Tenryo Maru quickly sank at 46°46′N 144°16′E / 46.767°N 144.267°E / 46.767; 144.267 killing 773 out of 947 men of the 23rd Air Defense Battalion, 26 gunners, and 83 sailors.[4] Sterlet also severely damaged Kuretake Maru which sank the following day with a death toll of 272 soldiers and six sailors.[4][5][6][7]

Fate[edit]

On 15 July 1945, off Otaru, she was damaged along with CD-55 and Etorofu-class escort ship Kasado by U.S. Navy planes from Task Force 38.[1]

On 14 August 1945, while escorting a freighter, she was torpedoed and sunk by the submarine USS Torsk off Tottori in the Sea of Japan (at 35°41′N 134°38′E / 35.683°N 134.633°E / 35.683; 134.633).[8] On 15 November 1945, she was struck from the Navy List.[1]
