The USCGC Mariposa (WLB-397) was an Iris-class buoy tender belonging to the United States Coast Guard launched on 14 January 1944 and commissioned on 1 July 1944.[1]
The Iris-class buoy tenders were constructed after the Mesquite-class buoy tenders. Mariposa cost $926,446 to construct and had an overall length of 180 feet (55 m). She had a beam of 37 feet (11 m) and a draft of up to 12 feet (3.7 m) at the time of construction, although this was increased to 14 feet 7 inches (4.45 m) in 1966. She initially had a displacement of 935 long tons (950 t; 1,047 short tons); this was increased to 1,026 long tons (1,042 t; 1,149 short tons) in 1966. She was powered by one electric motor. This was connected up to two Westinghouse generators which were driven by two CooperBessemer GND-8 four-cycle diesel engines. She had a single screw.[2]
The Iris-class buoy tenders had maximum sustained speeds of 13 knots (24 km/h; 15 mph), although this diminished to around 11.9 knots (22.0 km/h; 13.7 mph) in 1966. For economic and effective operation, they had to initially operate at 8.3 knots (15.4 km/h; 9.6 mph), although this increased to 8.5 knots (15.7 km/h; 9.8 mph) in 1966. The ships had a complement of six officers and seventy-four crew members in 1945; this decreased to two warrants, four officers, and forty-seven men in 1966. They were fitted with a SL1 radar system and QBE-3A sonar system in 1945. Their armament consisted of one 3"/50 caliber gun, two 20 mm/80 guns, two Mousetraps, two depth charge tracks, and four Y-guns in 1945; these were removed in 1966.[2]

Upon receiving her commission Mariposa was assigned to the 3rd Coast Guard District and homeportedinStaten Island where she was used for general ATON until the end of World War II.[1] After the end of the war, she stayed in Staten Island. In 1990, she underwent a major renovation and from June 1991, until being decommissioned, she was stationed in Seattle.[1]
In 2000, she was transferred to the U.S. Navy for use as a training hulk.[1]
