The Fantome class was a six-ship class of 4-gun screw composite sloops built for the Royal Navy during 1873 and 1874.

Design

Construction

Fantome and her sister ships were constructed with an iron frame that was sheathed in teak and copper (hence 'composite').

Propulsion

The ships were powered by a two-cylinder horizontal compound-expansion steam engine supplied by Humphrys, Tennant & Co. This engine powered an 11-foot (3.4 m) diameter screw. Steam was generated by three cylindrical boilers operating at 60 pounds per square inch (4.1 bar). The indicated horsepower varied from 836 to 1,011 ihp (623 to 754 kW). Additionally, Daring was equipped with a trunk engine provided by John Penn & Sons.

Sailing rig

All ships in the class were provided with a full barque rig.

Armament

The Fantome class carried two 7-inch (180 mm) and two 64-pounder muzzle-loading rifles, all mounted on pivots.

Evaluation

Built during a significant technological change in naval architecture, these composite sloops became obsolete before they were completed. Nevertheless, they served an important role on the far-flung stations of the British Empire, including participation in minor wars, such as the Perak War. They were also used for hydrography, and for this reason, Egeria was retained until 1911.
