The '''''Stromboli'' class''' was a group of two vessels designed by Sir [[William Symonds]] the [[Surveyor of the Navy]]. The design was approved on 29 August 1838.<ref>Lyon Winfield, page 159</ref> The vessels were of the {{sclass|Medea|destroyer|5}} design but were altered to the new [[Draft (hull)|draught]] derived from the {{sclass|Gorgon|monitor|5}}. The ships were initially classified as Steam Vessels Second Class (SV2) and were later classified as First Class [[Sloop-of-war|sloops]].<ref>Winfield</ref> The ships were built in two Royal Dockyards ([[HMNB Portsmouth|Portsmouth]] and [[Sheerness Dockyard|Sheerness]]). Both ships were at the [[Egyptian–Ottoman War (1839–1841)|bombardment of Acre]] in 1840. Both were in the [[Black Sea|Black]] and [[Azov Sea|Azov]] seas during the Russian War. They served on various stations of the Empire. ''Vesuvius'' was sold in 1865 and ''Stromboli'' in 1866. Both were broken by White at East Cowes on the Isle of Wight.<ref>Lyon Winfield, page 159</ref>

''Stromboli'' was the only named vessel in the [[Royal Navy]].<ref>Colledge, Stromboli</ref>

''Vesuvius'' was the eleventh named vessel (spelt ''Vesuvius'' or ''Vesuve'') since it was used for a 8-gun [[Fire ship|fireship]], launched by Taylor of [[Cuckold's Point]] on 30 March 1691 and expended on 19 November 1693 at [[Saint-Malo]].<ref>Colledge, Vesuvius</ref>

==Design and specifications==
Both vessels were ordered 12 March 1838 and laid down in September at Portsmouth and Sheerness. The vessels were launched in July (''Vesuvius'') and August (''Stromboli'') 1839.<ref>Lyon Winfield, page 159</ref> The gundeck was {{convert|180|ft|0|in|m|abbr=off|2}} with the keel length of {{convert|157|ft|0.75|in|m|abbr=off|2}} reported for tonnage. The maximum beam was {{convert|34|ft|4|in|m|abbr=off|2}} with {{convert|34|ft|0|in|m|abbr=off|2}} reported for tonnage. The depth of hold was {{convert|21|ft|0|in|m|abbr=off|2}}. The light draught forward was {{convert|13|ft|0|in|m|abbr=off|2}} and {{convert|13|ft|5|in|m|abbr=off|2}} aft. The builder's measure was calculated at 965 <small>79/94</small> tons whereas the vessels displaced 1,283 tons.<ref>Winfield</ref>

[[Robert Napier and Sons|Robert Napier & Sons]] of [[Govan]] supplied the machinery for both vessels. They were equipped with two fire-tube rectangular boilers. The engines were 2-cylinder vertical single expansion (VSE) [[Marine steam engine#Side-lever|side-lever steam engine]]s rated at 280 nominal horsepower (NHP). This gave the ships a speed under power of about {{convert|9|kn|km/h}}.<ref>Lyon Winfield, page 159</ref> Pictures show ''Vesuvius'' with a [[barque]] rig.

All four ships were initially armed with two 10-inch 84 hundredweight (cwt) shell Millar's original guns on pivot mounts and two 68-pounder 64 cwt muzzle-loading smooth bore (MLSB) carronades and two 42-pounder (22 cwt) MLSB carronades on broadside trucks.<ref>Winfield</ref> In 1856 the 10-inch guns were replaced with a Dundas 1853 68-pounder 84 cwt MLSB gun and the carronades were replaced with four 32-pounder 42 cwt MLSB guns on broadside trucks. In the 1860s the 68-pounder was replaced with an Armstrong 7-inch rifled breechloader (RBL) gun. This weapon is also known as the 100/110-pounder gun depending on the weight of shell fired.<ref group=Note>"cwt", or "[[hundredweight]]" refers to the weight of the gun itself. "68-pounder" refers to the weight of the ball fired</ref><ref>Lyon Winfield, page 159</ref> They had a complement of approximately 149 men and grew to 160 men with the change in armament.<ref>Winfield</ref>
