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

In 1998, the US Congress authorized the sale of Triumph,[4] without the towed sonar array, to the Philippines for $11,370,000.[5] However, the sale was not completed.

Design

The Stalwart-class ocean surveillance ships were succeeded by the longer Victorious-class ocean surveillance ships. Triumph had an overall length of 224 feet (68 m) and a length of 203 feet 6 inches (62.03 m) at its waterline. It had a beam of 43 feet (13 m) and a draft of 15 feet (4.6 m). The surveillance ship had a displacement of 1,600 tonnes (1,600 long tons; 1,800 short tons) at light load and 2,301 tonnes (2,265 long tons; 2,536 short tons) at full load. It was powered by a diesel-electric system of four Caterpillar D-398 diesel-powered generators and two General Electric 550 metric horsepower (540 shp; 400 kW) electric motors. This produced a total of 3,200 metric horsepower (3,200 shp; 2,400 kW) that drove two shafts. It had a gross register tonnage of 1,584 and a deadweight tonnage of 786.[6]

The Stalwart-class ocean surveillance ships had maximum speeds of 11 knots (20 km/h; 13 mph). They were built to be fitted with the Surveillance Towed Array Sensor System (SURTASS) system. The ship had an endurance of thirty days. It had a range of 3,000 miles (2,600 nmi; 4,800 km) and a speed of 11 knots (20 km/h; 13 mph). Its complement was between thirty-two and forty-seven. Its hull design was similar to that of the Powhatan-class fleet ocean tugs.[6]
