The USS Coos Bay (AVP-25) was a Barnegat-class small seaplane tender constructed by Lake Washington Shipyards in Houghton, Washington. Laid down on August 15, 1941, and launched on May 15, 1942, she was commissioned into the United States Navy on the same day, serving from 1943 to 1946. The vessel measured a typical Barnegat-class size, designed for reliability and seaworthiness, though specific dimensions are not provided in the source. During World War II, USS Coos Bay played a vital role in Pacific operations. She departed San Diego on July 22, 1943, heading towards Pearl Harbor and subsequently established a seadrome for Patrol Squadron 71 at Espiritu Santo. Her service included operating from various locations such as Tulagi, Blanche Harbor, and Green Island until June 1944. She supported fleet air operations, carried men and equipment, and served as a station tender at Saipan from September to December 1944. Notably, during her voyage to Ulithi Atoll in March 1945, she collided with the M/V Matagorda, which required her to undergo emergency repairs at Eniwetok. She returned to Pearl Harbor and remained there until the end of hostilities in August 1945. For her wartime service, she received two battle stars. After the war, Coos Bay served in Japan, arriving at Ominato Ko in September 1945 for station tender duties until December. She was decommissioned on April 30, 1946, and placed in reserve. Recognized for her seaworthiness and adaptability, she was transferred to the Coast Guard in 1949, where she was converted into a weather-reporting and ocean station vessel, designated USCGC Coos Bay (WAVP-376, later WHEC-376). Stationed at Portland, Maine, she performed meteorological data collection, search and rescue missions, law enforcement, and acted as a relay point for communications in the Atlantic Ocean. Her notable rescues include downed aircraft crews in 1953, 1955, and 1960, as well as survivors from a British merchant ship in 1964. Reclassified as a high endurance cutter in 1966, she was decommissioned on September 1, 1966, and returned to the U.S. Navy in 1967. The vessel was ultimately sunk as a target on January 9, 1968, off the coast of Virginia after being struck from the Naval Register. The USS Coos Bay's service exemplifies the versatility and longevity of the Barnegat-class ships in both wartime and peacetime roles, including significant contributions to oceanic weather reporting, search and rescue, and maritime law enforcement.
