HMS Defiance was the last wooden line-of-battle ship launched for the Royal Navy. She never saw service as a wooden line-of-battle ship. In 1884 she became a schoolship.

Design

Defiance was a development of the Renown class. The second pair of Renown's, HMS Atlas and HMS Anson, had a modified, finer stern run. Defiance was originally laid down as to the same plan as Atlas, but a new plan dated 8 October 1858 was prepared giving Defiance a lengthened bow.[2]

Defiance was the last ship to use the midsection design that Isaac Watts created for HMS James Watt.[3]

Career

Her trials off Plymouth on 5 February 1862 were conducted when she was neither masted nor stored. The trial speed of 11.886 knots (22.013 km/h) was worse than the similar trials of Atlas (13.022 knots) and Anson (12.984 knots). However Defiance's lack of sea service means that there can be no certainty as to whether her design was an improvement on Atlas.[4]

On 26 November 1884 Defiance became the Devonport torpedo and mining schoolship.[5] A special railway station to serve personnel travelling to and from the school, known as "Defiance Platform", was situated just west of Saltash railway station from 1905 until 1930.

She was sold on 26 June 1931 to Castle's Shipbreaking Yard for dismantling at Millbay, Plymouth.[6] Doige's Annual for 1932 poignantly describes her as "the last of England's 'Wooden Walls'".
