The USS Catalpa (AN-10/YN-5) was an Aloe-class net laying ship built to serve the U.S. Navy during World War II. Launched on 22 February 1941 by Commercial Iron Works in Portland, Oregon, and sponsored by Mrs. E. B. Colton, she was initially placed in service on 20 June 1941 in the 12th Naval District. She was officially commissioned on 22 May 1942 at Alameda, California. The vessel's primary role was to deploy and maintain anti-submarine nets, providing vital harbor protection in the Pacific theater. Constructed as a net-laying vessel, Catalpa measured typical dimensions for her class, equipped with gear suitable for laying, tending, and repairing harbor and fleet entrance nets. After loading equipment at Tiburon, California, she departed for the South Pacific, arriving at Nandi and Suva, Fiji, in June 1942. Throughout her service in the Solomon Islands, including Funafuti in the Ellice Islands, she laid and maintained harbor entrance nets protecting key bases. Early in 1944, she underwent overhaul in Dunedin, New Zealand, where she was redesignated AN-10. Catalpa participated in significant operations, including supporting the invasion of Peleliu in September 1944 and preparing Kossol Passage in the Palau Islands as a major fleet anchorage. Her duties extended beyond net tending to include laying mooring buoys, salvage, towing, and providing divers for maintenance tasks. She played a crucial role in maintaining fleet safety and logistics in the Pacific, contributing to the operations in the Philippines, Ulithi, and Eniwetok until mid-1945. After World War II, Catalpa was stationed in the Marshall Islands and then transferred to duty in the Eleventh Naval District in California. She was decommissioned on 21 October 1946 but was reactivated during the Korean War, returning to service in 1950. From 1952 to 1954, she operated primarily in Tokyo Bay and Guam, installing and tending nets. Her final assignment was at New London, Connecticut, where she was decommissioned and placed in reserve in October 1955. Throughout her service, USS Catalpa earned two battle stars for her World War II efforts, reflecting her vital contribution to naval defense and harbor security during the war.
