Brazilian destroyer Rio Grande do Norte (1909)

The ship had an overall length of 240 feet (73.2 m), a beam of 23.5 feet (7.2 m) and a draught of 7+5⁄6 feet (2.4 m). She was powered by 2 triple expansion reciprocating steam engines, driving two shafts, which developed a total of 7,778 indicated horsepower (5,800 kW) and gave a maximum design speed of 27 knots (50 km/h; 31 mph). During the trials the contract speed was exceeded, and the vessel was clocked at 27.27 knots (50.50 km/h; 31.38 mph).^[3] Steam for the turbines was provided by two double-ended Yarrow boilers. Rio Grande do Norte carried a maximum of 140 long tons (140 t) of coal that gave her a range of approximately 3,700 nautical miles (6,900 km; 4,300 mi) at 14 knots (26 km/h; 16 mph).

The ship mounted two 4 in (102 mm) guns in single mounts. In addition, four 47 mm (3pdr) cannons in single mounts were deployed at the time of launching.
