HMS Howe (1860)
HMS Howe was built as a 121-gun screw first-rate ship of the line of the Royal Navy.
She and her sister HMS Victoria were the first and only British three-decker ships of the line to be designed from the start for screw propulsion, but the Howe was never completed for sea service (and never served under her original name) as she had already been made obsolete by the first ironclad battleships.[1]
