T-AGOS Victorious class Swath-S (Small) Ocean Surveillance Ship

Victorious class ocean surveillance ships are built on a Small Waterplane Twin Hull, or SWATH, design for greater stability at slow speeds in high latitudes under adverse weather conditions. The SWATH design provides greater stability at slow speeds in high latitudes under adverse weather conditions.

T-AGOS ships are operated by the Military Sealift Command and are under the administrative command of Commander, Undersea Surveillance. They are deployed under the Operational Control (OPCON) of the Theater ASW Commanders, CTF 84 and CTF 12. Civilian technicians who operate and maintain the mission equipment man the SURTASS Operations Center (SOC), the nerve center of the ship. When operating with tactical forces, military detachments are embarked for onboard analysis and direct reporting to fleet units. A SURTASS mission consists of 60 days on station while towing an array of hydrophones that collect acoustic data.
