Catclaw (YN-81) was launched 22 May 1943 by Snow Shipyards, Inc., Rockland Me., sponsored by Mrs. F. R. Draper; commissioned 14 January 1944, Lieutenant T. A. Wall, USNR, in command; and reclassified AN-60 20 January 1944.
Catclaw reported at New London, Conn., 10 April 1944 to lay experimental underwater detection and sonar gear until 10 June. At Brooklyn Navy Yard, she was supplied with welding and diving equipment and had radar equipment installed, then sailed on 23 June for a month and a half of duty at Clyde, Scotland. On 20 August she arrived at Cherbourg, where she based until 14 September while laying moorings at Morlaix Roads for cargo ships bypassing the harbor at Brest. Through November, she played an essential part in the huge task of clearing the harbor of Le Havre, and after a month of operations at Plymouth, England, sailed for Charleston, S.C., 9 January 1945, aiding in the escort of a group of disabled ships including LCT -421 which she took in tow.
After overhaul, Catclaw sailed from Charleston 16 February 1945 for San Diego to load nets for Pearl Harbor. Here she had duty from 27 March until 25 May, when she cleared for Eniwetok and Guam to deliver nets. After receiving a new propeller at Guam she sailed to Saipan and Okinawa, where from 13 July to 8 September she conducted salvage operations. From 10 September to 14 October, she laid harbor buoys and issued dry stores at Sasebo, then returned to Okinawa to load acoustic minesweeping equipment for use in Japanese waters. She operated to support minesweepers off northern Kyushu through January 1946, then operated at Kobe until 14 March. Catclaw sailed then to Shanghai, where she was decommissioned 19 April 1946. The next day she was transferred to the Department of State for sale to China.
