HMNZS Resolution (A14) was a hydrographic survey vessel operated by the Royal New Zealand Navy from 1997 until 2012. Originally built as the United States Naval Ship USNS Tenacious (T-AGOS-17), she was part of the Stalwart-class ocean surveillance ships used during the Cold War for tracking Soviet submarines. Her construction contract was awarded in February 1987 to VT Halter Marine, Inc., and her keel was laid in February 1988. Launched in February 1989, she was commissioned into the U.S. Navy later that year as USNS Tenacious, serving primarily in collecting acoustic data on Soviet submarines using the SURTASS (Surveillance Towed Array Sensor System) array, which was a linear, neutrally buoyant listening device deployed on a long tow cable. In 1997, she was transferred to New Zealand and renamed HMNZS Resolution, a name honoring James Cook's ship HMS Resolution. Her transfer marked her transition from a Cold War surveillance vessel to a primary hydrographic survey ship, replacing HMNZ Ships Tui and Monowai. During her service with the RNZN, Resolution undertook extensive marine survey tasks, including work for Land Information New Zealand. The vessel also participated in educational initiatives, sponsoring scholarships and engaging university and high school students as part of the 'Students at Sea' program. Resolution played a notable role during the 2011 Canterbury earthquake, providing hydrographic surveys of the Port of Lyttelton following the disaster. She was decommissioned in April 2012 at Devonport Naval Base and subsequently sold to EGS Group, a private surveying company. Renamed RV Geo Resolution, she left New Zealand waters in October 2014 to continue her surveying career in the private sector. Her service history highlights her versatility, from Cold War surveillance to supporting New Zealand’s maritime charting and educational initiatives, emphasizing her maritime and strategic significance.
