HMS Tourmaline (J339) was a Catherine-class minesweeper that served with the Royal Navy during the Second World War. Originally constructed as USS Usage (AM-130), she was part of the United States Navy's Auk class of minesweepers. The vessel was laid down on 1 January 1942 at the Gulf Shipbuilding Corporation in Chickasaw, Alabama, and was launched on 4 October 1942. As part of the lend-lease agreement, she was transferred to the United Kingdom on 7 June 1943, where she was commissioned as HMS Tourmaline (J339). Constructed primarily for minesweeping operations, HMS Tourmaline was deployed in the Atlantic Ocean during the war, contributing to Allied efforts to maintain safe passage for military and merchant vessels by clearing mines. Her service in the Atlantic was part of the broader Allied naval strategy to secure sea lanes against the threat of mines, although specific notable events during her wartime service are not detailed in the available source. Following the conclusion of World War II, HMS Tourmaline was returned to U.S. custody in January 1947, struck from the Navy list, and transferred to the Foreign Liquidation Commission for disposal. Her subsequent sale led to her service with the Turkish Navy, where she was renamed Çardak. She remained in Turkish service until 1974, marking a long operational life beyond her initial military role. In summary, HMS Tourmaline was a wartime minesweeper built in the United States, transferred to the Royal Navy, and later served in the Turkish Navy, exemplifying the multi-national use of naval vessels during and after World War II. Her construction, service in the Atlantic, and post-war transfer highlight her significance as a vessel involved in key naval mine-clearing operations and international military support during this period.
