HMS Swift was a sloop-of-war built in 1762 at the shipyard of John Greave in Limehouse, on the River Thames, and launched in 1763. The vessel measured approximately 28 meters (92 feet) in length and was armed with a complement of 14 six-pounder guns (weighing 2.7 kilograms each) and 12 swivel guns of half a pound. Its design and armament positioned it as a relatively small, agile warship suited for exploration and patrol duties. Based at Port Egmont in the Falkland Islands, HMS Swift was primarily engaged in exploratory missions along the Patagonian coasts before the winter of 1770. During one such voyage, a storm forced the ship to seek refuge near present-day Puerto Deseado. While entering the Río Deseado, the ship ran aground on a submerged rock. Despite efforts to lighten the vessel by jettisoning cargo and freeing herself from the initial obstacle, Swift encountered a second uncharted rock. The ship ultimately sank at approximately 18:00 on 13 March 1770 along the coast of Puerto Deseado. The sinking resulted in the loss of three crew members out of ninety-one—namely the cook and two soldiers. The cook's body was recovered days later and was given an impromptu burial. At the time of the wreck, HMS Swift was under the command of Captain George Farmer. The ship's mission was to defend the British base at Port Egmont and to undertake exploratory voyages along South America's southern coast. The wreck site remained largely unknown until its rediscovery in 1982 by young amateur divers. The discovery marked the beginning of underwater archaeology in Argentina and contributed to the development of national laws governing the exploration and preservation of underwater cultural heritage. The wreckage was investigated primarily by the National Institute of Anthropology and Latin American Thought (INAPL), and the find included the remains of one of the lost soldiers, whose burial was commemorated ashore. This vessel's archaeological significance lies in its role as a key site for understanding 18th-century British maritime exploration and naval operations in the region.
