Velasco was a Spanish Navy Alsedo-class destroyer in commission from 1924 to 1957. She served in the Rif War in 1925 and fought on the Nationalist side during the Spanish Civil War of 1936–1939. While in commission, she served the Kingdom of Spain from 1924 to 1931, the Second Spanish Republic from 1931 to 1936, the civil war's Nationalist faction from 1936 to 1939, and the Francoist Spanish State from 1936 to 1957.

The Alsedo class was designed jointly by the British companies Vickers and John Brown & Co.[2] The Alsedo class was of similar layout to the Hawthorn Leslie variant of the British M-class destroyer.[3][4]

The ships were 86.25 metres (283 ft) long overall and 83.82 metres (275 ft), with a beam of 8.23 metres (27 ft) and a draught of 4.57 metres (15 ft). Displacement was 1,060 tonnes (1,043 long tons) standard and 1,336 tonnes (1,315 long tons) full load.[4] They were propelled by two geared steam turbines driving two shafts and fed by four Yarrow boilers and had a distinctive four-funneled silhouette. The ships a design speed of 34 knots (63 km/h; 39 mph). They were the first Spanish Navy ships to use only fuel oiil and could carry 276 tonnes (272 long tons) of oil, giving them a range of 1,500 nautical miles (2,800 km; 1,700 mi) at 15 knots (28 km/h; 17 mph). The ships had a crew of 86.[4]

The Alesdo-class ships were armed with three Vickers 4-inch (102 mm) guns manufactured under license in Spain and mounted in three single mounts, with one forward, one aft, and one between the second and third funnels, as well as two anti-aircraft guns,[4] identified by different sources as either 47-millimetre[4] or 2-pounder (40 mm) guns.[5][6] The anti-aircraft guns later were replaced by four 20 mm autocannons.[4][5] Four 533-millimetre (21 in) torpedo tubes were mounted in twin banks, and the Alsedo class ships were the first Spanish destroyers to carry torpedoes of that size.[4] The ships were fitted with two depth charge throwers sometime around 1945.[5] A rangefinder was mounted on each ship's bridge.[7]

By the time the Alsedo class entered service in the mid-1920s, destroyer design had advanced and made them obsolete. The Spanish Navy therefore cancelled plans to build three more ships of the class and instead next constructed the more modern and much larger Churruca-class destroyers.[4] Nonetheless, the Alsedo class had active and lengthy careers.[8]

Construction and commissioning

The Spanish Cortes (Parliament) passed a navy law on 17 February 1915 authorizing a large program of construction for the Spanish Navy, including three Alsedo-class destroyers to be built in Spain at the Sociedad Española de Construcción Naval (SECN) shipyard at Cartagena.[1][2] SECN was part of the same British consortium that included the ship's designers, Vickers and John Brown & Co.[2]

World War I (1914–1918) caused shortages of materials and equipment sourced from the United Kingdom and delayed construction of the Alsedo class, and Velasco′s keel was not laid at the SECN shipyard until 6 July 1920.[8] She was launched on 16 June 1923 and delivered to the Spanish Navy on 27 December 1924.[8]
