HMS Myrmidon was a Hermes-class sixth-rate post ship constructed for the Royal Navy in the 1810s. Laid down in July 1812 at Milford Dockyard, Wales, and launched on 18 June 1813, she was completed at Plymouth Dockyard by February 1814. The vessel measured approximately 119 feet 11 inches (36.6 meters) in length at the gundeck, with a keel length of 99 feet 10 inches (30.4 meters). Her beam was 31 feet (9.4 meters), with a draught of 10 feet 3 inches (3.1 meters), and a depth of hold of 8 feet 8 inches (2.6 meters). Her tonnage was 509 tons burthen. Myrmidon was armed with a total of twenty guns, comprising eighteen 32-pounder carronades and two 9-pounder cannon serving as chase guns. The ship's complement consisted of 135 officers and ratings, reflecting her role as a versatile warship suitable for various duties within the Royal Navy. Commissioned initially in August 1813 under Captain Valentine Gardner, she was still fitting out at the time. Subsequent command changes saw Captain Henry Bourchier take over in October 1813, followed by Captain William Patterson in 1814, and then Captain Robert Gambier in April 1815. Her early service included deployments in the Mediterranean and later on the Africa Station, where she was recommissioned in 1818 under Commander Henry John Leeke. During her service on the Africa Station, she was active until her decommissioning in October 1822. Myrmidon’s service was relatively brief, spanning about a decade, and she played a role in the Royal Navy's operations during the post-Napoleonic period. She was paid off in 1818, reclassified as a 20-gun sloop in 1817, and ultimately broken up at Portsmouth Dockyard in January 1823. Her construction and service exemplify the typical design and operational pattern of early 19th-century sixth-rate ships, contributing to Britain’s naval dominance during that era.
