HMS ''Hannibal'' was a pre-dreadnought battleship built for the Royal Navy, and the sixth ship to bear the name HMS ''Hannibal''. The ship was laid down at the Pembroke Dock in May 1894, she was launched in April 1896, and commissioned into the fleet in April 1898. She was armed with a main battery of four guns and a secondary battery of twelve guns. The ship had a top speed of . ''Hannibal'' served with the Channel Fleet (later reorganised to the Atlantic Fleet) after commissioning in 1898. In 1906 she underwent a refit, which included a conversion from a coal burner to using oil. She was placed in reserve from 1907, only to be mobilised in July 1914 as a precautionary measure prior to the outbreak of World War I. From August 1914 to February 1915 ''Hannibal'' was a guard ship at Scapa Flow. Later that year, her main armament was removed and she was converted to a troopship, serving in this capacity during the Dardanelles campaign. From November 1915 to the end of the war, she served as a depot ship based in Alexandria, Egypt. She was disposed of in 1920 and scrapped later that year. == Design == (詳細はlong overall and had a beam of and a draft of . She displaced up to at full combat load. Her propulsion system consisted of two 3-cylinder vertical triple-expansion steam engines powered by eight coal-fired cylindrical boilers. By 1907–08, she was re-boilered with oil-fired models.

She had a crew of 672 officers and enlisted men. The ship was armed with four BL 12-inch Mk VIII guns in twin turrets, one forward and one aft. The turrets were placed on pear-shaped barbettes; six of her sisters had the same arrangement, but her sisters and and all future British battleship classes had circular barbettes. ''Hannibal'' also carried twelve QF 6-inch /40 guns. They were mounted in casemates in two gun decks amidships. She also carried sixteen QF 12-pounder guns and twelve QF 2-pounder guns. She was also equipped with five 18-inch (450-mm) torpedo tubes, four of which were submerged in the ship's hull, with the last in a deck-mounted launcher. ''Hannibal'' and the other ships of her class had 9 inches (229 mm) of Harvey armour, which allowed equal protection with less cost in weight compared to previous types of armour. This allowed ''Hannibal'' and her sisters to have a deeper and lighter belt than previous battleships without any loss in protection. The barbettes for the main battery were protected with of armour, and the conning tower had the same thickness of steel on the sides. The ship's armoured deck was thick.
