HMS Orion was a Belleisle-class ironclad of the Victorian Royal Navy, originally built for the Ottoman Empire under the name Bourdjou-Zaffer. Constructed by Samuda Brothers at Cubitt Town, London, she was designed by Ottoman naval architect Ahmed Pasha. Her construction was initiated for the Ottoman Navy, but in 1878, amidst the Russo-Turkish War, she was purchased by the British Government before completion. Her design was modified to align with British naval standards, and she was launched in January 1879, with her first commission commencing on 24 June 1882. The vessel measured approximately 320 feet in length with a beam of about 68 feet, and she displaced around 6,040 tons. She was armed with four 12-inch (305 mm) muzzle-loading rifles mounted in a broadside arrangement, a unique feature as she and her sister ship, HMS Belleisle, were the only British ships ever to carry 12-inch guns in this configuration. Her armor and internal layout were designed to support her heavy artillery, emphasizing her role as a formidable ironclad. HMS Orion’s service included reinforcing the Mediterranean Fleet, although she arrived too late to participate in the Bombardment of Alexandria in June 1882. She contributed to land operations during the Battle of Tell El Kebir in September of the same year. After a period in reserve at Malta, she was recommissioned in 1885, notably shadowing a Russian armored cruiser during tensions following the Panjdeh incident, demonstrating her role in naval reconnaissance and power projection. Throughout her career, Orion served as a guardship at Singapore and later returned to the Mediterranean. She was involved in a notable collision with the battleship Temeraire in 1890 but was repaired and continued service. Declared non-effective in 1901, she was repurposed as a depot-ship for torpedo boats at Malta, later renamed Orontes in 1910, serving as a store-ship before being sold in 1913. Her career highlights her evolution from a state-of-the-art ironclad to a support vessel, reflecting the rapid technological changes in naval warfare during her era.
