The Royal Navy's Victoria class (or Sans Pareil class) battleships of the 1880s was the first class which used triple expansion steam engines, previous battleships having used compound engines. There were only two ships in this class. The lead ship, HMS Victoria, was sunk in an accidental collision with another Royal Navy battleship in the Mediterranean with the loss of half of her crew. Her sister, HMS Sans Pareil survived until scrapped in April 1907.
