Decommissioned in June 2014: NOAA RV McArthur II was acquired from the U.S. Navy in 2002 and was converted by NOAA from a T-AGOS surveillance vessel to a multiple-disciplinary platform capable of a broad range of missions. As was it's predecessor, the McArthur, the McArthur II is named after William Pope McArthur. The vessel was operated by NOAA's Office of Marine and Aviation Operations. (NMAO), and was home ported at NOAA's Marine Operations Center, Pacific (MOP), in Seattle, Washington.

The ship conducted oceanographic research and assessments, throughout the eastern Pacific, including the U.S. West Coast, Central and South America. The McArthur II was involved in studies in several of the National Marine Sanctuaries on the west coast of the United States. The 224-foot ship engaged in measurements of chemical, meteorological, and biological sampling for several large scale programs within NOAA.

The McArthur II carried a complement of 5 officers, 17 crew members and up to 15 scientists. The scientists who carry out research aboard the McArthur II came from many divisions of NOAA, as well as other Federal and state government agencies, and academia.
