The Austal team’s TAGOS-25 Navy Ocean Surveillance Ship design leverages the company’s complex multi-hull design expertise. 

In the designation TAGOS (also written as T-AGOS), the T means the ships are operated by the Military Sealift Command (MSC); the A means they are auxiliary (i.e., support) ships; the G means they have a general or miscellaneous mission; and the OS means the mission is ocean surveillance. 

TAGOS ships support Navy anti-submarine warfare (ASW) operations. They gather underwater acoustical data to support the mission of the Integrated Undersea Surveillance System (IUSS) by providing a ship platform capable of theater anti-submarine acoustic passive and active surveillance using Surveillance Towed-Array Sensor System (SURTASS) equipment to gather undersea acoustic data. The Small Waterplane Area Twin Hull (SWATH) design has features (including very good stability in high seas) that are useful for SURTASS operations.

Capabilities

  • Theater anti-submarine acoustic passive and active surveillance
  • SURTASS equipment to gather undersea acoustic data
  • SWATH design provides good stability in high seas, useful in SURTASS operations
  • Larger and faster than in-service TAGOS ships
