NRP Tâmega was a Guadiana-class destroyer built for the Portuguese Navy in the early 1920s.
Design
The Portuguese Navy had struggled to secure funding for new ships after the 1890s, when a number of protected cruisers and smaller craft had been built. The navy nevertheless made repeated attempts for ambitious construction programs. After the toppling of the Portuguese monarchy in 1910, the navy submitted another large construction plan in 1912, which the new republican government passed (and then reduced in scope in 1913). The revised plan called for two new cruisers, six destroyers, and three submarines; the Guadiana class of four destroyers comprised a significant part of the program.[1] The design for the new ships was prepared by Yarrow Shipbuilders.[2]
The ships of the Guadiana class were 73.2 m (240 ft 2 in) long, with a beam of 7.2 m (23 ft 7 in) and a draft of 2.3 m (7 ft 7 in). They displaced 515 long tons (523 t) standard and up to 660 long tons (670 t) at full load. They had a crew of 80 officers and enlisted men. The ships were powered by two Parsons steam turbines, with steam provided by three Yarrow water-tube boilers that were vented through individual funnels. The engines were rated to produce 11,000 shaft horsepower (8,200 kW) for a top speed of 27 knots (50 km/h; 31 mph). At a more economical speed of 15 knots (28 km/h; 17 mph), the ships could cruise for 1,600 nautical miles (3,000 km; 1,800 mi).[2][3]
The ship carried an armament that consisted of a single 102 mm (4 in) gun and two 76 mm (3 in) guns, along with four 457 mm (18 in) torpedo tubes. The 102 mm gun was placed on the forecastle and the 76 mm guns were mounted on the centerline further aft, one between the first and second funnel and the other gun further aft. The torpedo tubes were in twin mounts, also on the centerline, one aft of the third funnel and the other at the stern.[2][3]
Service history
Tâmega was built at the Lisbon Naval Base and was launched on 21 October 1922.[3]
The ship was eventually discarded around 1945.[3]
