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.

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.

When operating independently as in a deep ocean surveillance mission, acoustic data is transmitted to shore via satellite for analysis and reporting. SURTASS ships have proudly operated throughout the world supporting the Undersea Warfare/Anti-Submarine-Warfare mission of all five numbered fleets of the U.S. Navy.

This is either the Victorious (T-AGOS 19) or Effective (T-AGOS 21).
