How thick was the armour of HMS Devastation?

HMS Devastation was armed with armor ranging from 250 to 300 mm in thickness. This level of armoring was significant for its time, as it provided enhanced protection against not only traditional naval artillery but also the emerging technologies of naval warfare, such as explosive shells. The thick armor was especially crucial in protecting vital areas such as the machinery spaces and ammunition magazines, which were critical for the operational capability of the ship. The specific thickness of the armor allowed HMS Devastation to withstand direct hits more effectively than many of its contemporaries and was part of the innovation seen in warship design during the late 19th century, which moved towards heavier and more effective armoring solutions to address the threats posed by modern naval weapons.
