HMS Northumberland (1866)

HMS Northumberland was the last of the three Minotaur-class armoured frigates built for the Royal Navy in the 1860s, ordered on 2 September 1861 from the Millwall Ironworks and laid down there on 10 October 1861. She measured 400 feet between perpendiculars, displaced about 10,584 long tons and was driven by a two-cylinder trunk steam engine from John Penn and Sons to a best speed of 14.1 knots. Unlike her half-sisters she carried a mix of seven, eight and nine inch rifled muzzle-loading guns and was armoured only over her battery and along the waterline. She stuck on the slip for years and was finally floated off with pontoons on 17 April 1866, just as her builders went bankrupt, so the liquidators seized her. She was completed on 8 October 1868 at a cost of 444,256 pounds, served mainly in the Channel Squadron, became a stokers training ship, then a coal hulk, and was scrapped in 1935.
