context_page_description: HMS Firebrand was a wooden paddle vessel launched in 1831. She was rebuilt in 1843, renamed HMS Black Eagle and employed as an Admiralty steam yacht. She was broken up in 1876.
context_section_description: Built at Merchant's Yard, Limehouse as a wooden paddle vessel, Firebrand was launched on 11 July 1831. In 1832 her original Butterley side lever steam engine was removed and replaced in 1833 by a Maudsley, and Morgan's paddlewheels were fitted. She was rebuilt in 1843, gaining 13 feet (4.0 m) in length, and receiving an oscillating engine manufactured by John Penn and Sons.  Notably, Penn doubled the power output without increasing either the weight or space occupied. On 29 October 1853, she assisted in the refloating of HMS Rodney, which had run aground in the Dardanelles. Firebrand was renamed Black Eagle on 5 February 1842.
  In 1856, the Black Eagle and the paddle-wheel troopship Dee were used in a trial of J Wethered's apparatus for superheated steam.  This produced an economy of fuel of 18% in the Black Eagle, and 31% in the Dee.
