Itsukushima (厳島) was the lead ship in the Matsushima class of protected cruisers of the Imperial Japanese Navy. Like her sister ships, (Matsushima and Hashidate) the name Itsukushima comes from one of the traditional Three Views of Japan, in this case, the Itsukushima Shrine in Hiroshima prefecture on the Seto Inland Sea, home to a famous Shinto-Buddhist shrine dedicated to the Buddhist goddess Benzaiten.

Forming the backbone of the Imperial Japanese Navy during the First Sino-Japanese War, the Matsushima-class cruisers were based on the principles of Jeune Ecole, as promoted by French military advisor and naval architect Louis-Émile Bertin.[1] The Japanese government did not have the resources or budget to build a battleship navy to counter the various foreign powers active in Asia; instead, Japan adopted the radical theory of using smaller, faster warships, with light armor and small caliber long-range guns, coupled with a massive single 320 mm (12.6 in) Canet gun. The design eventually proved impractical, as the recoil from the huge cannon was too much for a vessel of such small displacement, and its reloading time was impractically long; however, the Matsushima-class cruisers served their purpose well against the poorly equipped and poorly led Imperial Chinese Beiyang Fleet.

Itsukushima was built by the Société Nouvelle des Forges et Chantiers de la Méditerranée naval shipyards at La Seyne-sur-Mer, in France, and was launched on 18 June 1889.[2] She underwent trials by the builder in September and October, and achieved an average maximum speed of 16.78 knots on 15 October 1890.

Design

Armour and armament sketch of Itsukushima and Hashidate

Itsukushima differed from her sister ship Hashidate primarily in that her windows were square instead of rectangular, and in that Hashidate had a stronger engine.

Itsukushima had a steel hull with 94 frames constructed of mild steel, and a double bottom, divided into waterproof compartments, with the area between the bulkheads and armor filled with copra. The bow was reinforced with a naval ram. The vital equipment, including boilers and ammunition magazines, were protected by hardened steel armor, as were the gun shields. The main armament consisted of one breech-loading 320 mm (13 in) Canet gun mounted in the bow of the ship, which could fire 450 kg (992 lb) armor-piercing or 350 kg (772 lb) explosive shells at an effective range of 8,000 meters (8,700 yd). The maximum rate of fire was two rounds per hour, and the ship carried 60 rounds. Secondary armament consisted of twelve QF 4.7 inch Gun Mk I–IV Armstrong guns, with a maximum range of 9,000 meters (9,800 yd) and maximum rate of fire of 12 rounds/minute. Ten were mounted on the gun deck, five to each side, with the eleventh gun located on the upper deck of the fantail, with a twelfth mounted on the lower deck of the fantail. Each gun was equipped with 120 rounds. Tertiary protection was by six QF 6 pounder Hotchkiss mounted in sponsons on the upper deck, with a maximum range of 6,000 meters (6,600 yd) and rate of fire of 20 rounds/minute. Each gun had 300 rounds. In addition, eleven QF 3 pounder Hotchkiss were mounted at various locations, with range of 2,200 meters (2,400 yd) rate of fire of 32 rounds/minute and 800 rounds per gun. Each ship in the class also had four 356 mm (14 in) torpedo tubes, three in the bow and one in the stern, with a total of 20 torpedoes carried on board. The weight of all of this weaponry led to the design becoming dangerously top-heavy, and armor was sacrificed in an effort to reduce weight.[3]

The ship was driven by two horizontal triple expansion steam engines. However, the design had problems with seaworthiness, and the design speed was seldom attained in operation.[3]
