HMAS Launceston (J179/B246/A120) was a Bathurst-class corvette constructed during World War II, named after the city of Launceston, Tasmania. As one of 60 corvettes built under the Bathurst class, she was designed as a versatile, locally produced vessel capable of anti-submarine and mine-warfare duties. The initial concept in 1938 envisioned a smaller 500-ton vessel with a speed of 10 knots and a 2,000 nautical mile range, but the design was expanded to approximately 680 tons, with a top speed of 15.5 knots and a range of 2,850 nautical miles. Armed with a 4-inch gun and equipped with asdic, Launceston could be fitted with depth charges or minesweeping gear, making her a flexible asset for convoy escort and patrol duties. Launceston was laid down by Evans Deakin & Co in Brisbane on 23 December 1940 and launched on 30 June 1941. She was commissioned into the Royal Australian Navy on 9 April 1942. Her early service involved convoy escort duties around Australian waters, but she soon deployed to the Indian Ocean, joining the British Eastern Fleet in September 1942. During her wartime service, Launceston participated in convoy escort missions and notably contributed to the destruction of Japanese submarine Ro-110 on 11 February 1944, in collaboration with sister ship HMAS Ipswich and the Indian sloop HMIS Jumna. After a refit in September 1944, she continued anti-submarine patrols from Fremantle until February 1945, when she joined the British Pacific Fleet at Manus Island. Launceston took part in the Battle of Okinawa, marking her significant involvement in the Pacific Theater. Post-war, Launceston served in Hong Kong as a minesweeper and anti-piracy patrol vessel before returning to Australia in late 1945. She made official visits to Tasmanian ports, including her namesake city. Over her wartime career, she earned four battle honours: "Pacific 1942–45," "Indian Ocean 1942–44," "East Indies 1944," and "Okinawa 1945." In 1946, she was transferred to the Turkish Navy, initially named TCG Ayancik, serving as a minelayer and minesweeper until her withdrawal from military service in 1965. She was later transferred to the Turkish Seamanship College and renamed Hamit Naci. Launceston's service exemplifies the versatility and importance of the Bathurst-class corvettes in Allied maritime operations during and after World War II.
