USNS Triumph (T-AGOS-4)

USNS Triumph (T-AGOS-4) was a Stalwart-class ocean surveillance ship of the United States Navy. She was struck from the Naval Vessel Register in 1995. Triumph is currently awaiting disposal.

Stalwart class ships were originally designed to collect underwater acoustical data in support of Cold war anti-submarine warfare operations in the 1980s.

US Congress as per Section 201(f) authorizes the sale to the Philippines of the Ocean Surveillance Ship TRIUMPH (T-AGOS 4). This 12 year-old vessel has over half of its service life remaining (16 years) and originally cost the United States $25,493,000. The Government of the Philippines is expected to pay $11,370,000 for the vessel. However, the transfer of the vessel will be completed without a towed sonar array.
