HMS ''Rover'' was an 18-gun iron screw corvette built for the Royal Navy in the 1870s, the sole ship of her class. The ship was initially assigned to the North America and West Indies Station until she returned home in 1879. She was transferred to the Training Squadron when it formed in 1885. ''Rover'' was not really suitable for such a role and she was placed in reserve four years later and then sold for scrap in 1893. ==Design and construction== ''Rover'' was designed in 1872 by Edward Reed, the Director of Naval Construction, as an improved version of the s.〔Ballard, p. 62.〕 She displaced tons, nearly larger than the older ships.

Ballard believes that one cause of her poor performance under sail was due to the drag of her uneven fore-and-aft trim. Her propeller could be hoisted up into the stern of the ship to reduce drag while under sail.〔 The ship was initially armed with a mix of 7-inch and 64-pounder 64 cwt〔"cwt" is the abbreviation for hundredweight, 64 cwt referring to the weight of the gun.〕 rifled muzzle-loading guns. All sixteen 64-pounders were mounted on the broadside while the two guns were mounted underneath the forecastle and poop deck as chase guns.〔Ballard, p. 64.〕 In 1880, the ship was rearmed with 14 BL 6-inch 80-pounder breech-loading guns. One gun each was mounted at the bow and stern as chase guns while the remainder were broadside guns. Two carriages for torpedoes were added as well.〔 ''Rover'' was laid down at the yards of the Thames Ironworks and Shipbuilding Company at Leamouth, London in 1872. She was launched on 12 August 1874 and completed on 21 September 1875〔 at a total cost of £169,739.
