Cadmus-class sloop
 The Cadmus class was a six-ship class of 10-gun screw steel sloops built for the Royal Navy between 1900 and 1903. This was the very last class of the Victorian Navy's multitude of sloops gunvessels and gunboats to be constructed and they followed the traditional pattern for 'colonial' small warships with a full rig of sails. After them the Fisher Reforms of the Navy ended the construction and deployment of this type of vessel.
