Fate:
To conform with the Washington Disarmament Treaty of 1920 the 12 inch gun was removed.
She was refitted as a submarine minelayer capable of carrying more than 100 mines. The method of laying the mines over the stern by the use of a conveyor belt proved more than successful and she suffered no disasters in her career.

Scrapped in 1932.
