The USS Matagorda (AVP-22/AG-122) was a United States Navy Barnegat-class seaplane tender constructed at the Boston Navy Yard, with her keel laid on September 6, 1940. Launched on March 18, 1941, and commissioned on December 16, 1941, she was designed to support seaplane operations during World War II. The vessel measured a standard displacement typical of Barnegat-class ships and was built to be seaworthy and reliable, with good habitability for her crew. Initially stationed in Boston, she undertook shakedown and training in Chesapeake Bay before deploying to various operational theaters. By May 1942, Matagorda was operating in the Galápagos Islands, relieving USS Osmond Ingram and tending to Patrol Wing 3 seaplanes. Her duties included tending aircraft, escorting merchant ships, and conducting supply runs across Central and South America, notably from bases in Honduras and Colombia. She also engaged in escorting convoys across the Atlantic to the United Kingdom, making multiple trips to Pembroke and Bristol, England, and participating in supply runs to Casablanca, French Morocco, and Gibraltar. Throughout 1944, Matagorda operated along the Brazilian coast, rescuing the crew of the torpedoed SS William Gaston and other downed aircraft crew members. She also conducted extensive training and supply missions in Brazilian waters and was involved in the search and rescue of downed airmen. In late 1945, she was assigned to be converted into a press information ship to support the projected invasion of Japan, but the war ended before this conversion was completed. She was subsequently decommissioned in February 1946 and laid up in the Atlantic Reserve Fleet. Transferred to the Coast Guard in 1949, she was reconfigured as a weather-reporting ship designated USCGC Matagorda (WAVP-373). Her Coast Guard duties included ocean station patrols, weather reporting, search and rescue, and law enforcement in the Atlantic and later in the Pacific from Honolulu. Notable incidents include rescuing survivors from torpedoed vessels and towing disabled ships. She was reclassified as a high endurance cutter (WHEC-373) in 1966 and served until her decommissioning at Honolulu on October 15, 1967. The vessel was stricken from the Naval Vessel Register in 1968 and was ultimately sunk as a target in 1969 off Hawaii.
