HMS Hero was a 91-gun, second-rate, screw-powered, modified built for the Royal Navy during the 1850s. Completed in 1859, she initially served with the Channel Squadron and then conveyed Edward, Prince of Wales, to North America in 1860. The ship spent most of 1862 at the North America and West Indies Station before being paid off towards the end of the year. Hero was sold for scrap in 1871.
Description The ships of the line were built in response to the perceived threat from France by the construction of the steam-powered Napoléon-class ships of the line.Lambert, p. 124 Heros design was modified by the Surveyor of the Navy, Baldwin Wake Walker, by lengthening her keel by and fining the lines of her bow with respect to her half-sisters. The ship measured on the gundeck and on the keel. She had a beam of , a depth of hold of , a deep draught of . Hero displaced and had a tonnage of 3,148 tons burthen. The ship was fitted with a two-cylinder, single-expansion steam engine built by Maudslay, Sons and Field that was rated at 600 nominal horsepower and drove a single propeller shaft. During her sea trials on 5 November 1858, Heros boilers provided enough steam for the engine to produce that was good for a speed of . Her crew numbered 860 officers and ratings.Winfield, p. 39
The ships had three masts and were ship-rigged. To reduce drag and improve performance under sail, the Agamemnons could hoist their propeller into the hull and retract the telescoping funnel. The ships were regarded as very manoeuverable for steamships, able to match sailing ships in their ability to tack and wear with precision.Lambert, pp. 57, 63, 122, 124
The ships' muzzle-loading, smoothbore armament consisted of thirty-four shell guns on their lower gundeck and thirty-four 32-pounder (56 cwt) guns"Cwt" is the abbreviation for hundredweight, 56 cwt referring to the weight of the gun. on their upper gundeck. Between their forecastle and quarterdeck, they carried twenty-two 32-pounder (45 cwt) guns.Winfield, p. 37 The single 68-pounder gun was positioned on the forecastle as a pivot gun so that it could serve as a bow chaser.Lambert, p. 35
Construction and career Hero was the fourth ship of her name to serve in the Royal Navy.Colledge, Warlow & Bush, p. 196 Unlike her half-sisters that had been ordered as 80-gun ships, she was ordered as a 91-gun ship on 27 March 1852. The ship was laid down at Chatham Dockyard on 8 June 1854 and launched on 15 April 1858. Hero was commissioned at Sheerness Dockyard by Captain George Broke. He was invalided out of the service on 29 April and replaced by Captain Henry Seymour. The ship completed on 10 May and was assigned to the Channel Squadron.
The ship was selected in 1860 to host the Prince of Wales during his tour of North America and she departed HM Dockyard, Devonport, on 12 July. His return was delayed by prolonged contrary winds and he did not arrive until 16 November, by which time, only one week's provisions remained and the royal party was reduced to eating salted beef and pork like the crew.Clowes, p. 157 Captain Alfred Ryder relieved Seymour on 5 January 1861 and the ship was transferred to the North America and West Indies Station. Hero was paid off at Sheerness on 22 November 1862. Her armament was reduced to 89 guns that same year, 79 guns during 1863–1869 and 71 guns until she was sold for scrap to Henry Castle & Sons on 20 June 1871 to be broken up at Charlton.
