Driver-class sloop

The Driver class were a class of paddlewheel steam sloops of the British Royal Navy. Six Driver-class ships were ordered in 1840[2] and a further ten in March 1841, although only six were built. Five were ordered in 1847, but all were either build as paddle frigates or cancelled.[1]

Design

The ships were designed by Sir William Symonds. They were built of wood, displaced 1,590 tons and had a length on the gundeck of 180 feet (54.9 m).[1]

Propulsion

Power was provided by a two-cylinder direct-acting steam engine driving paddle wheels. Spiteful had a side-lever steam engine, Devastation had a 4-cylinder 'Siamese' steam engine and Sphinx had a 2-cylinder oscillating steam engine. The engines developed between 280 and 300 nominal horsepower, apart from Devastation (400 nhp) and Sphinx (500 nhp). All the ships were capable of about 9 knots (17 km/h) under steam, with the more powerful Devastation and Sphinx making 10 or 12 knots.[1] A brig rig was fitted for operating under sail.

Armament

All three ships were armed with two 10 in (250 mm) (84 cwt) guns on pivot mounts, two 68-pounder (64 cwt) guns and two 42-pounder (22cwt) carronades.[Note 2][1] In 1856 the armament was changed to a single 10-inch pivot gun, a 68-pounder (95cwt) gun and four 32-pounder (42 cwt) guns. Later, the 68-pounder was replaced by a 110 pdr Armstrong gun breech-loading gun.[1]

Crew

They had a complement of approximately 149 men, increasing later to 160.[1]
