Description and Construction
Line drawing of the Pará class

In 1904 Brazil adopted an ambitious plan to renovate and modernize its Navy. The Naval Renovation Program was negotiated and enacted in December 1904 and envisioned acquisition of large number of vessels, including a dozen destroyers. In 1906 the program was modified reducing the total number of destroyers to ten.[4] These ships became known as Pará-class destroyers.

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 6,563 indicated horsepower (4,894 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 27.21 knots (50.39 km/h; 31.31 mph).[3] Steam for the turbines was provided by two double-ended Yarrow boilers. Piauí 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.

Upon completion of sea trials, Piauí was officially delivered to the Brazilian government on December 21, 1908, with Captain Pedro de Frontin serving as her commander. She left Yarrow's yard on December 28, and departed for Brazil on December 31. The destroyer reached Falmouth in the morning of January 2, 1909, spent three days there, leaving for Vigo on January 5 and reaching it two days later. Piauí departed Vigo on January 10 for Lisbon where she arrived on the same day. The destroyer left Lisbon on January 23 and reached Las Palmas on January 25. On January 30 she sailed out from Las Palmas for Cabo Verde, arriving in St. Vicente on February 1. After spending four days in port, Piauí left St. Vicente on February 5, and successfully arrived in Recife shortly after 11:00 on February 10, 1909.[5] At about 04:00 on February 14, 1909 the ship departed Recife for Bahia where she arrived after a 21 hour journey.
