TAGOS-25 Navy Ocean Surveillance Ship
SWATH ocean surveillance ship for Military Sealift Command supporting Navy anti-submarine warfare with SURTASS towed arrays and integrated electric propulsion.
Description
TAGOS-25 ships support Navy anti-submarine warfare by gathering undersea acoustic data for the Integrated Undersea Surveillance System using Surveillance Towed-Array Sensor System (SURTASS) equipment. The Small Waterplane Area Twin Hull (SWATH) design gives good stability in high seas, and the ships are larger and faster than in-service TAGOS ships. The surface ships page cites a $3.2 billion contract for up to seven ships.
