She was the lead ship of the first British A-class submarines and the only one to have a single bow torpedo tube. She was actually sunk twice: first in 1904 when she became the first submarine casualty, with the loss of all hands; however, she was recovered, but sank again in 1911, this time when she was unmanned. The wreck was discovered in 1989 and was designated under the Protection of Wrecks Act in 1998.[2] The wreck is a Protected Wreck managed by Historic England.
