Antioquia-class_destroyer
The Antioquia class of destroyers consisted of two ships, ARC Antioquia and ARC Caldas, used by the navy of Colombia, the Armada Nacional República de Colombia, between 1934 and 1961. Initially constructed at the Lisbon Naval Arsenal as part of the Portuguese Navy's Douro class, they were acquired by Colombia before completion in response to the Peruvian purchase of two destroyers during the war with Peru. They arrived too late to see service in the conflict and saw little action during their service lives. They underwent a major refit in the mid-1950s which saw their armament completely redone. Following their removal from service in 1961, they were broken up for scrap.

The Antioquia class was initially a version of the Portuguese Navy's Douro class. The design was by the British company Yarrow Shipbuilders, based on that of the Royal Navy's prototype destroyer HMS Ambuscade. The Antioquia-class destroyers were acquired by Colombia before completion but were built to standard Douro-class specifics. The Douro class closely resembled many British designs in the interwar period.[1][2] The destroyers were 323 feet 0 inches (98.5 m) long overall and 307 feet 0 inches (93.6 m) between perpendiculars with a beam of 31 feet 0 inches (9.4 m) and a mean draught of 8 feet 11 inches (2.7 m). The ship had a standard displacement of 1,219 long tons (1,239 t) and was 1,563 long tons (1,588 t) fully loaded.[3]
The vessels were powered by three oil-fired Yarrow boilers providing 400 psi (2,758 kPa) of steam to two Parsons turbines with Curtiss reduction gearing. These turned two shafts and was rated at 33,000 shaft horsepower (24,608 kW) with a maximum speed of 36 knots (67 km/h; 41 mph). The destroyers had capacity for 292 long tons (297 t) of fuel oil and a range of 5,400 nautical miles (10,000 km; 6,200 mi) at 15 knots (28 km/h; 17 mph).[4]
The Antioquia class was armed with four BL 4.7-inch (119 mm) guns with two mounted forward in single turrets with gun shields and two mounted aft in a similar fashion. 140 rounds were carried for each gun. The destroyers were equipped with three single-mounted 40-millimetre (1.6 in) "pom-poms" with two on the aft shelter deck and one between the funnels. They were also armed with two quadruple banks of 21-inch (533 mm) torpedo tubes mounted centrally, two depth charge throwers with twelve depth charges and were fitted for minelaying with 20 naval mines carried.[4]

Originally ordered by the Portuguese government in 1930 as part of a new building programme. In conjunction with Yarrows, the Lisbon Naval Arsenal of Lisbon was chosen to construct two hulls while Yarrows would provide and install the destroyer's machinery. Named Douro and Tejo, the two hulls constructed in Lisbon were sold to Colombia before completion in response to the Colombia–Peru War, in response to the Peruvian acquisition of two destroyers.[1][6] Portugal order two further ships to replace them. Douro was renamed Caldas and Tejo was renamed Antioquia.[1]
The war with Peru was shortlived and the Antioquias did not enter service before the war ended. Both ships were launched in 1933 and were commissioned in 1934. The two destroyers saw little action as Colombia remained neutral during World War II. However, the Colombian Navy did perform neutrality patrols into the Caribbean Sea after the German submarine U-154 began attacking shipping off its shores. Caldas patrolled the Caribbean Sea on 29–30 March 1944 searching for the submarine. In the 1940s, two 20 mm (0.79 in) cannon were added amidships.[3]
Following the war, the destroyers returned to their tranquil service until 1952 when Antioquia began a major refit, beginning at Cartagena before going to the United States in 1953. Caldas underwent the same refit in 1954–1955. Both ships were refitted in the United States when two 5-inch (127 mm)/38 calibre guns replaced the four 4.7-inch guns, one forward and one aft. The destroyers were fitted with Mk 52 fire control, three more 40 mm guns and a hedgehog anti-submarine mortar.[3] The number of torpedo tubes was reduced to one quadruple mount.[5] Antioquia was decommissioned on 23 January 1961, and Caldas on 3 March 1961, with both ships being scrapped.[3]
