This image is of HMS Howe. She was a 121-gun screw 3 deck ship of the line (one of only 2 designed from the start for screw propulsion), but was never completed for sea service as ironclad battleships were making unarmoured two and three deckers obsolete at this time and she only received 12 guns.
She never served under her own name as she became the training ship Bulwark in 1885, being renamed Impregnable in 1886 and back to Bulwark in 1919. She was broken up in 1921.
