Designed by Nathaniel Barnaby, the Royal Navy Director of Naval Construction, the hull was of composite construction; that is, iron keel, frames, stem and stern posts with wooden planking. This class of composite sloops was unique in having an internal steel deck over the machinery and magazines for protection. The Satellite class were reclassified as corvettes in 1884, and no more composite or wooden corvettes were built - in fact, Pylades was the last corvette built for the Royal Navy until the Second World War.
Propulsion was provided by a horizontal compound expansion of 1,400 indicated horsepower (1,044 kW) driving a single screw.
All the ships of the class were built with a barque rig.
The class was designed with two 6-inch/100-pounder (81cwt) breech loaders and ten 5-inch/50-pounder (38cwt) breech loaders, plus a single light gun and four (or more) machine guns. Heroine, Hyacinth and Royalist were built with eight 6-inch/100-pounder (81cwt) breech loaders in place of the 5-inch/6-inch mixture, and Satellite was converted to the same fit.
