HMS Caledonia was a broadside ironclad of the Prince Consort class.

Originally laid down as steam two-decker line-of-battle ship of the Bulwark class, HMS Caledonia, HMS Triumph (later renamed Prince Consort) and HMS Ocean were converted on the building stocks to armoured frigates.

The three ships of the Prince Consort class were intended to improve on HMS Royal Oak, which is often referred to as a half-sister to the rest of the class. In reality, the greater engine power was offset by the increased weight of engines and coal which had to be carried, so that the class had almost a two foot greater draft as compared to Royal Oak, which caused their performance to be essentially identical.

[edit] 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She was temporarily withdrawn from service in 1866 for reconstruction, which involved the addition of a poop deck.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 September 30, 1886.
