HMS Sulphur was a 10-gun bomb vessel of the Hecla class, launched in 1826 for the British Royal Navy. Designed for bombarding fortifications, her construction featured a robust hull capable of carrying heavy ordnance, though specific dimensions are not provided in the source. The vessel gained notable recognition through her extensive service and exploration missions. Initially, in 1829, Sulphur transported Lieutenant-Colonel Frederick Irwin, officers, passengers, and troops from the 63rd Regiment of Foot to the Swan River Colony, demonstrating her role in colonial support. In 1830, Sulphur participated in a rescue operation with boats from HMS Cruiser, pulling the grounded vessel Medina off Parmelia Reef near the Swan River, highlighting her involvement in maritime assistance. By 1835, Sulphur was converted into a survey ship and became part of an expedition to explore the Pacific coast, under orders to chart from Valparaíso to 63°30' N. Command was initially held by Captain Frederick Beechey, who departed due to illness in 1836, with Henry Kellett and later Edward Belcher taking command. During this voyage, Sulphur visited key locations including New Archangel (Sitka), where she was greeted with a colonial ball, and Yuquot at Nootka Sound, engaging with indigenous leaders. The expedition also reached the Columbia River and San Blas, advancing British knowledge of the Pacific Northwest and Central America. Sulphur's service extended into the First Opium War (1840–1841), during which she participated in military operations. In 1841, she was severely damaged in a typhoon at Hong Kong, resulting in her total dismasting. Subsequently, she was used for harbor surveys, notably of Hong Kong, before returning to England in 1842. From 1843, she served in harbor duties until she was broken up by 1859, becoming the last bomb vessel on the Navy List. The vessel's historical significance is marked by her role in exploration, scientific study, and military conflicts, as well as her connection to maritime history in the Pacific region. The naming of Sulphur Channel near Hong Kong commemorates her contributions.
