HMS Triumph was a broadside ironclad battleship of the Victorian era, the sister-ship of HMS Swiftsure. These two ships comprise the Swiftsure class of 1870. The two sister-ships, which were built side by side by Palmers, were designed and built specifically to serve as flagships on distant stations, primarily with the Pacific squadron. They were powered by a Maudslay horizontal twin-cylinder return connecting-rod engine, and were the last British battleships to be fitted with a hoisting screw.
