Paraíba was a Pará-class destroyer of the Brazilian Navy, serving from 1909 to 1944. She was named after the Brazilian state of Paraíba.
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 6,700 indicated horsepower (5,000 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 27.29 knots (50.54 km/h; 31.40 mph). [3] Steam for the turbines was provided by two double-ended Yarrow boilers. Paraíba 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.
Her first commander was Captain Affonso de Fonseca Rodrigues.

The class comprised the lead ship Bahia and her sister Rio Grande do Sul, along with a canceled third ship, Ceara. Both were named after states of Brazil. As a class, they were the fastest cruisers in the world when commissioned, and the first in the Brazilian Navy to use steam turbines for propulsion.

NRP Espadarte was the first modern submarine of the Portuguese Navy. Preceded by Plongeur which was discarded in 1910, Espadarte was constructed at La Spezia Naval Base, Italy beginning in 1910 and was launched in 1912. The submarine was the basis for the establishment of the 1st Submarine Squadron of the Portuguese Navy. Espadarte was discarded in 1931.
The Foca class, or simply F, was the first naval class of submarines operated by the Brazilian Navy. It consisted of the F1, F3 and F5 submarines designed by Italian naval engineer Cesare Laurenti and built in La Spezia, Italy. The name Foca comes from the Portuguese vessel of the class. The class was part of Brazil's 1906 naval program to acquire warships to modernize its navy. The submarines were acquired to serve as a training and maintenance platform for the crews, with few naval actions during the 19 years they were active. The navy incorporated the class on 17 July 1914 and, as a result, expanded its naval structure to house these new vessels, such as the creation of the first naval school for submariners and the incorporation of ships designed to support submarines only.
