HMS Belleisle was one of the four ships that were under construction for foreign navies in British shipyards which were purchased by the British government for the Royal Navy in 1878, at the time of the Russian war scare.

HMS Orion was a Belleisle-class ironclad of the Victorian Royal Navy. Originally constructed for the Ottoman Empire, and called Bourdjou-Zaffer, she was purchased by the British Government before completion.
