===Propulsion===

The ''Cyclops''-class ships had two steam engines, each driving a single {{convert|12|ft|m|1|adj=on}} propeller. ''Cyclops'' and ''Hydra'' had 4-cylinder [[Marine steam engine#Compound|inverted compound steam engines]] made by John Elder that had a working pressure of {{convert|60|psi|kPa kg/cm2|0|abbr=on|lk=on}}. The engines produced a total of {{convert|1472|-|1528|ihp|lk=onin}} on [[sea trial]]s which gave the ships a maximum speed around {{convert|11|kn|lk=in}}. The engines used by ''Hecate'' and ''Gorgon'' were built by Ravenhill and were simple horizontal 4-cylinder [[Marine_steam_engine#Direct_acting|direct acting steam engines]]. Their working pressure was {{convert|34|psi|kPa kg/cm2|0|abbr=on}} and they produced a total of {{convert|1579|-|1709|ihp}} for about the same speed. The first pair of ships carried {{convert|250|LT|t}} of coal while the second pair carried {{convert|270|LT|t}}.<ref>Ballard, pp. 246–49</ref> This was enough to steam {{convert|3000|nmi|lk=in|abbr=on}} at {{convert|10|knots|abbr=on}}.<ref>Silverstone, p. 169</ref>
