USNS Henson (T-AGS-63) is an oceanographic survey ship operated by Military Sealift Command for the United States Navy and assigned to the United States Oceanographic Office-style survey mission supporting Naval Oceanographic Office objectives. Built at Halter Marine, Inc. and launched in 1999, Henson conducts hydrographic, bathymetric, and geophysical surveys worldwide using towed sonar arrays, sub-bottom profilers, and unmanned vehicles to support United States Atlantic Fleet, United States Fleet Forces Command, and allied maritime operations.
Henson was laid down by Halter Marine, Inc. in the late 1990s as part of the Pathfinder-class survey ship program, sister to USNS Pathfinder (T-AGS-60), USNS Sumner (T-AGS-61), and USNS Bowditch (T-AGS-62), incorporating commercial shipbuilding techniques similar to vessels built for Bath Iron Works and Ingalls Shipbuilding. The hull form and diesel-electric propulsion reflect design heritage linked to MARAD-style auxiliaries and follow standards promulgated by American Bureau of Shipping classification and NAVSEA engineering oversight. Launch ceremonies included representatives from Department of Defense, Naval Sea Systems Command, and regional stakeholders such as Alabama Shipbuilders advocates.
Henson is outfitted for multi-beam echo sounding, side-scan sonar, and sub-bottom profiling to produce high-resolution bathymetry for NATO and Navy Hydrographic Office charting requirements. Her sensor suite integrates systems from vendors used by Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, and Lamont–Doherty Earth Observatory researchers, enabling seabed mapping, geotechnical surveys, and acoustic data collection supporting ASW environments relevant to United States Atlantic Command operations. Onboard lab spaces and winch systems support lowered sensor arrays, remotely operated vehicles similar in concept to those deployed by NOAA and RV Atlantis (AGOR-25), and embarked specialists from Naval Research Laboratory and civilian contractors for expeditionary work. Communications, navigation, and meteorological suites provide interoperability with Multinational Force exercises and links to Global Positioning System timing maintained by United States Space Force heritage systems.
Assigned to the Military Sealift Command's Special Mission Ship program, Henson entered service supporting hydrographic missions in the Atlantic Ocean, Caribbean Sea, and global littorals where United States Navy forces operate. She has embarked civilian mariners from Seafarers International Union and technical teams from Naval Oceanographic Office, conducting survey missions used by National Geospatial-Intelligence Agency charting efforts and contributing data to NATO Sub-Committee on Oceans and Coastal Areas working groups. Henson supported peacetime charting, scientific collaboration with institutions like University of Miami (Rosenstiel School), and operational preparation for task forces under United States Sixth Fleet and United States Southern Command.
Henson participated in multinational exercises and humanitarian support surveys alongside units from Royal Navy, Royal Canadian Navy, French Navy, and Brazilian Navy forces during joint maritime operations. The ship conducted post-storm bathymetric surveys in waters affected by Hurricane Katrina and Hurricane Ike, aiding United States Coast Guard navigational safety efforts and port re-opening coordinated with Federal Emergency Management Agency. Henson also contributed to bathymetric and acoustic studies in collaboration with Woods Hole Oceanographic Institution and the Office of Naval Research for sea-floor characterization relevant to antisubmarine warfare and undersea infrastructure planning linked to Navy Expeditionary Combat Command priorities.
Throughout her service Henson earned operational commendations and recognition from Naval Oceanographic Office stakeholders for survey contributions to NATO charting and safety of navigation efforts; individual crew and civilian technical teams received awards from Military Sealift Command and interagency partners. The vessel has experienced routine maritime incidents common to survey platforms, including equipment casualties and weather-related mission interruptions addressed under Command investigations and maintenance actions by Norfolk Naval Shipyard-style repair facilities. Safety and environmental compliance follow standards influenced by International Maritime Organization conventions and Environmental Protection Agency maritime regulations.
As a non-commissioned asset operated by Military Sealift Command, Henson's lifecycle is governed by Naval Sea Systems Command maintenance cycles, mid-life upgrades, and potential transfer determinations analogous to previous Pathfinder-class dispositions. Decisions about deactivation, transfer to reserve status, sale, or scrapping would involve review by United States Department of Defense, General Services Administration, and allied interoperability considerations; until such formal action, Henson remains part of the Navy's oceanographic survey capability supporting National Ocean Policy-related missions.
