HMS Esk was a 21-gun Highflyer-class screw corvette launched on 12 June 1854 from J. Scott Russell & Co., Millwall.[2] She saw action in the Crimean War, the Second Opium War and the Tauranga Campaign in New Zealand, and was broken up at Portsmouth in 1870.
Esk was built in exchange for HMS Greenock (which went to the Australian Royal Mail Co.) by J. Scott Russell & Co. The words of the Admiralty Order stated she should be "a wood screw vessel complete of Highflyer's [class] in exchange when built".[1] This made her a small wooden frigate to a design by the Surveyor's Department of the Admiralty on 25 April 1847; she and her sister Highflyer were redesignated as corvettes in 1854. In common with other screw corvettes of the time, she was envisaged as a steam auxiliary, intended to cruise under sail with the steam engine available for assistance. Commensurately she was provided with a full square sailing rig. Her oscillating two-cylinder inclined single-expansion steam engine, provided by the builders, was quite different from Highflyer's, but developed broadly the same power — 657 indicated horsepower (490 kW) — and drove a single screw.[1]
Construction
She was laid down in April 1853 in the Millwall yard of J. Scott Russell & Co. on the River Thames. She was launched on 12 June 1854 and commissioned at Woolwich on 21 December 1854.[3]
