Service history

HMS Caledonia was not completed until July 1865 due to a delay in the delivery of her main armament. Once this was installed, she was commissioned as Second-in-Command of the Mediterranean Fleet, becoming the first ever armoured flagship of the Royal Navy.

She was temporarily withdrawn from service in 1866 for reconstruction which involved the addition of a poop deck. Following this, she was flagship of the Channel Fleet until 1867, when she was paid off for re-armament.

HMS Caledonia was flagship of the Mediterranean Fleet until 1869 (relieving HMS Victoria, the last three-deck Royal Navy flagship) until 1872. She was a guardship in the Firth of Forth from 1872 until 1875. She was paid off at Plymouth, and was laid up there until she was sold on 30 September 1886.
