HMS Pandora was a 24-gun Porcupine-class sixth-rate post ship of the Royal Navy, launched in May 1779. Designed by Surveyor of the Navy John Williams, it was an enlarged version of the Sphinx class, with ten ships of this class built. Pandora measured approximately 114 feet 7 inches (34.9 m) along the upper deck, with a keel length of 94 feet 9½ inches (28.9 m), a beam of 32 feet 3 inches (9.8 m), and a depth in the hold of 10 feet 3 inches (3.1 m). Its burthen was 524/94 tons, and it was constructed at Deptford Dockyard, costing around £5,716 to build, with an additional £5,909 for fitting out. The ship's armament consisted of twenty-two 9-pounder long guns on the upper deck, supplemented by two 6-pounder long guns on the forecastle. It had a crew complement of about 160 men. Pandora’s early service included patrolling in the Channel during the threatened invasion of 1779 and deploying in North American waters during the American War of Independence, primarily as a convoy escort between England and Quebec. Throughout the war, Pandora captured multiple American privateers and merchant vessels, including Jack, Terrible, Janie, Mercury, and others, demonstrating its active role in maritime conflicts. In 1790, Pandora was ordered back into service amid escalating tensions with Spain. Under Captain Edward Edwards, the ship was refitted with additional armament—four 18-pounder carronades—and set sail on 7 November 1790. Its mission was to pursue the mutineers of HMS Bounty, who had escaped to Tahiti. Pandora captured several mutineers, including midshipmen Peter Heywood and George Stewart, and crew members who had remained loyal to Bligh. The ship searched the South Pacific for several months, visiting islands such as Tahiti, Tokelau, Samoa, Tonga, and Rotuma. Tragically, Pandora wrecked on the Great Barrier Reef on 29 August 1791, during her return voyage from the Pacific. The ship ran aground and sank, resulting in the loss of 35 lives, including four mutineers. The survivors, including Captain Edwards, managed to escape in open boats and reach safety in Timor. The wreck, located approximately 5 km northwest of Moulter Cay at 11°23′S 143°59′E, is one of the best-preserved in Australian waters. Discovered in 1977, it has been extensively excavated and studied by marine archaeologists, revealing about 30% of the hull intact. The Pandora remains a significant maritime archaeological site, emblematic of the era’s naval history and the famous Bounty mutiny.
