HNoMS Horten (A530) was a Norwegian support vessel constructed in 1977 at Karljohansvern in Horten, Norway. Designed initially to serve as a support craft for submarines and fast attack crafts, the ship was modified during construction, resulting in a shorter vessel with smaller torpedo stores, which diminished its original offensive support capabilities. Instead, Horten primarily functioned in logistical roles, providing food, fuel, and water to smaller ships, and occasionally offering onboard facilities to visiting crews. The vessel was notably spacious, boasting well-appointed accommodations. Privates had four-man cabins, leading privates had two-man cabins, and some petty officers enjoyed single cabins. Commissioned officers had high-standard cabins, with the captain's quarters being particularly large and equipped with top-tier amenities. The ship also featured guest quarters for high-ranking officers and a dedicated officers’ mess hall with a bar, reflecting her role as a support and hospitality vessel. In 1985, Horten was repurposed as a royal yacht for King Olav V during the repair of the royal yacht HNoMY Norge, highlighting her versatile facilities. In 1986, Horten was laid up but returned to service in 1989 as a training ship within the Norwegian Navy's "School squadron," providing cadets practical experience in navigation and command alongside her support functions. Throughout the 1990s and early 2000s, she alternated between training duties and support roles, including serving as a command vessel during NATO exercises such as "Blue Game." Between 2005 and 2008, she primarily served as a living and training center for crews of the new Nansen-class frigates. Horten was decommissioned in 2008 after decades of service, with her sale delayed by legal and logistical issues. In 2012, she was sold to CAS-Global Ltd, which intended to operate her under a UK flag with Nigerian interests. However, her transfer was marred by legal controversies, allegations of corruption, and eventual seizure in Nigeria. As of 2014, she was employed as a fishery patrol vessel in Nigeria, marking a significant transition from her original support vessel role in the Norwegian Navy.
