'''USNS ''Mizar'' (MA-48/AGOR-11/AK-272)''' was a vessel of the United_States_Navy. She was named after the star, Mizar.
''Mizar'' was built as a small ice-strengthened cargo ship of the ''Eltanin'' class on a Maritime Administration type (C1-ME2-13a) hull, by Avondale Marine Ways, Inc. from January 1957. She entered service on March 7, 1958 and served as part of the Military_Sea_Transportation_Service, working around Canada and Greenland, with a single voyage to Antarctica in 1961.
In 1963 she was chosen for a major conversion. On April 15, 1964 she was reclassifed '''AGOR-11''', designed for deep oceanographic search and research and fitted with a deepsea probe, equipped with strobe lights, cameras, sonar, and magnetometer. She was then operated by the MSTS under the Naval_Research_Laboratory, Washington. Her major tasks were ocean floor study and service as a floating base for underwater acoustic, chemical, and biological research.
She was assigned to Military_Sealift_Command Pacific in 1975 and underwent another major modification in 1980.
Mizar took part in the search operations for {{USS|Thresher|SSN-593}}, the nuclear weapons lost off Palomares, Spain, and the extended search for {{USS|Scorpion|SSN-589}} - which was found in October, 1968. She has also taken part in searches for foreign wrecks, including ''Eurydice'' and Soviet submarines including ''K-129''.
She was withdrawn from active service in the 1990s and reclassified as '''AK-272'''. Currently she is part of the National_Defense_Reserve_Fleet in the James River, Fort_Eustis,_Virginia and is listed for disposal. Bay Bridge Enterprizes, LLC, was awarded a contract for the dismantling and recycling of ''Mizar'' on 21 July 2005.
