The USS Thrush (AM-18) was a Lapwing-class minesweeper built for the United States Navy, designed for the hazardous task of detecting and removing naval mines. Laid down on 27 May 1918 by Pusey and Jones Co. in Wilmington, Delaware, she was launched on 15 September 1918 and commissioned on 25 April 1919. Her initial service involved operations in the North Sea, where she arrived in June 1919 to assist with clearing the North Sea Mine Barrage, a significant obstacle following World War I, serving with Squadron 3 of the Minesweeping Detachment. After detaching in November 1919, she called at Brest, France, before returning to the U.S. Later assigned to Mine Division 3, Mine Squadron 4, she was redesignated AM-18 in July 1920 and joined the U.S. Pacific Fleet, initially based at San Pedro, Los Angeles, then moving her operations to Pearl Harbor. She participated in peacetime exercises until her decommissioning at Pearl Harbor on 3 April 1922, remaining inactive for over 13 years. Recommissioned in October 1935, she was refitted at Mare Island Navy Yard and converted into a small seaplane tender, redesignated AVP-3 in January 1936. She operated out of Seattle, then Panama, and later in the Caribbean, supporting patrol and neutrality operations during the early stages of World War II. In December 1941, she arrived in Brazil just as Japan attacked Pearl Harbor, marking her entry into wartime service. During WWII, Thrush conducted patrols along the Brazilian coast, provided aid to distressed merchant vessels—including towing the SS Commandante Lyra after a U-boat attack—and supported convoy escort missions. She also served in various roles such as refueling aircraft, transporting supplies, and acting as a floating radio station. Her operations extended to the Galápagos and Panama Canal Zone. After the war, she returned to the U.S., visiting Pearl Harbor and the East Coast, before being decommissioned on 13 December 1945. The vessel was struck from the Navy List in January 1946 and sold to John A. Pohl. The USS Thrush's service highlights her versatility as a minesweeper, seaplane tender, and auxiliary vessel throughout her operational life, especially during pivotal moments of early 20th-century naval history.
