HMS Warrior is considered to be 'rather unique' as a warship - as she was equipped with both sails, and a steam engine (that was fuelled by coal):
This meant that she could navigate the oceans of the World, using one of three modes: i) just her sails. ii) just her steam engine. iii) both her sails and her steam engine - when speed was of the essence! Her sails, though retained from the days of HMS Victory (1803), also meant that Warrior had a useful fallback, in the event that she run out of coal. Despite this, her steam engine was connected to a single propeller, which could be regarded as the grandfather of all modern ship propellers (because it was of a simpler design - with only two blades). In any case, Warrior's propeller was designed, to push her 9000 tons, through the sea lanes of the British Empire.
