The USCGC Chelan was a Lake-class cutter constructed by Bethlehem Shipbuilding Corporation in Quincy, Massachusetts, with her keel laid down on November 14, 1927. She was launched on May 19, 1928, and commissioned into the United States Coast Guard on November 5, 1928. The vessel was primarily assigned to the Bering Sea Patrol, operating out of Seattle, Washington, with annual patrols beginning in April 1929. Her duties included search and rescue, law enforcement, and maritime patrols in the challenging conditions of the northern Pacific. Chelan’s service included notable rescue operations, such as in 1931 when she responded to the wreck of the motor vessel Gladiator near Unimak Island. During this incident, Chelan’s crew attempted to rescue the stranded crew under harsh weather conditions; despite losing her lifeboat, Chelan successfully transported the rescued crew to Seattle, including a critically ill individual who recovered after medical treatment. In 1937, Chelan was reassigned from Seattle to Boston, Massachusetts, expanding her operational scope to the North Atlantic. She responded to distress calls from vessels like the Norwegian steamer SS Bjerkli, rescuing and transporting crew members safely to port. She also played a role in the International Ice Observation Service and the International Ice Patrol, supporting maritime safety in the North Atlantic. During World War II, Chelan was transferred to the Royal Navy under the Lend-Lease Act on May 2, 1941, and renamed HMS Lulworth (Y60). As part of the Royal Navy, she served as a convoy escort in the Atlantic, Mediterranean, and Indian Ocean theaters. She engaged in anti-submarine actions, notably forcing the scuttling of the Italian submarine Pietro Calvi in July 1942. Lulworth participated in significant wartime operations, including escorting convoys in Burma and operations in the Indian Ocean. After the war, she was returned to the U.S. Coast Guard in 1946, resuming her original name, Chelan. She was subsequently sold on October 23, 1947. Throughout her service life, Chelan/Lulworth exemplified versatility and resilience in both peacetime patrols and wartime convoy escort operations, marking her as a significant vessel in maritime security and rescue history.
