The Etna class was a series of protected cruisers that were built in the late 1880s for the Regia Marina (the Royal Italian Navy). The four ships built were slightly enlarged copies of the Elswick Works' design for the protected cruiser Giovanni Bausan. Etna, the lead ship of the class, was the only ship still in service when World War I began, although she served as a stationary headquarters ship for the Navy Commander-in-Chief in Taranto for the duration of the war. The three later ships all participated in putting down the Boxer Rebellion as part of the Eight-Nation Alliance. The three were struck from the Navy List before 1912, but Etna was not sold for scrap until 1921.

Design and description

The design of the Etna-class protected cruisers was based on that of Sir W G Armstrong Mitchell & Co.'s Elswick Works' earlier Giovanni Bausan, which was the first modern protected cruiser constructed for the Italian Navy. She proved successful enough that the Italians negotiated for a license to build copies in Italian shipyards. George Rendel and Carlo Vigna designed the ships. The first three ships varied somewhat in their displacement and engine power, and the last ship, Ettore Fieramosca, was slightly longer than the others. [1]

The Etna-class ships measured 283 feet 6 inches (86.4 m) between perpendiculars, with a beam of 42 feet 6 inches (13.0 m). They had a mean draft of 19 feet (5.8 m) and displaced between 3,373–3,474 long tons (3,427–3,530 t). They carried a crew of 12 officers and 296 men. [2] Ettore Fieramosca was 290 feet (88.4 m) between perpendiculars and had a beam of 43 feet 4 inches (13.2 m). She had a draft of 18 feet 9 inches (5.7 m) and displaced 3,538 long tons (3,595 t). Her crew consisted of 17 officers and 298 men. [3]

Propulsion

The Etna-class cruisers had two horizontal compound steam engines, each driving a single propeller. Their engines were powered by four double-ended cylindrical boilers. On sea trials the engines produced a total between 6,252–7,480 indicated horsepower (4,662–5,578 kW) and the ships reached between 17–17.8 knots (31.5–33.0 km/h; 19.6–20.5 mph). The ships carried between 575–620 long tons (584–630 t) of coal which allowed them to steam for 5,000 nautical miles (9,300 km; 5,800 mi) at a speed of 10 knots (19 km/h; 12 mph). [1]

Armament and armor

The main armament of the ships consisted of two Armstrong 10-inch (254 mm), 30-caliber breech-loading guns mounted in barbettes fore and aft. Each gun had an approximate firing arc of 240°. "To load, the gun was laid fore and aft in line with a fixed armored deckhouse into which ammunition was hoisted from below." [4] They fired a 450-pound (200 kg) shell at a muzzle velocity of 2,060 ft/s (630 m/s). The six 6-inch (152 mm), 32-caliber, breech-loading guns were carried in sponsons along the sides of the ships in Vavasseur mountings. The guns fired a shell that weighed 100 pounds (45 kg) at a muzzle velocity of 1,940 ft/s (590 m/s). [4]

For anti-torpedo boat defense the first three ships mounted five 57-millimeter (2.2 in) 6-pounder Hotchkiss guns. Each shell weighed about 6 lb (2.7 kg) and could be fired at 20 rounds per minute. Their muzzle velocity of 1,765 ft/s (538 m/s) gave them a range of about 8,700 meters (9,500 yd). [5] Another five 37-millimeter (1.5 in) 1-pounder Hotchkiss guns were also carried. They fired a shell weighing about 500 g (1.1 lb) at a muzzle velocity of about 610 m/s (2,000 ft/s) to a range of about 3,200 meters (3,500 yd). They had a rate of fire of about 30 rounds per minute [6] Etna, Stromboli, and Vesuvio were fitted with four 14-inch (356 mm) torpedo tubes. One was mounted in the bow underwater and the other three were above water. [2] Ettore Fieramosca's anti-torpedo boat armament differed slightly from that of her half-sisters. She carried six 6-pounder and eight 1-pounder Hotchkiss guns, but only three torpedo tubes. [3]

The cruisers were fitted with an armored deck below the waterline with a maximum thickness of 1.5 inches (38 mm) and had a belt of cork at their waterline, which was intended to seal holes by swelling through water absorption after being hit. [4] This proved to be unsuccessful as hits would result in the destruction of the cork and it tended to deteriorate quickly. The breech and loading area of the main guns was protected by an armored hood 2 inches (51 mm) thick. [4]

Operational history

Etna served in the Squadra Permamente (Permanent Squadron) from her commissioning to 1893 and then served in North and South American waters until the end of 1895. [2] From April to June 1893, she participated in the International Naval Review at Hampton Roads that was part of the Columbian Exposition. [7] Afterward she was stationed in the Red Sea during the First Italo-Ethiopian War of 1895–1896 and then supported Italian interests during the Cretan Revolt of 1898. [8] The ship was then transferred to the Far East, returning home in 1902. Etna was disarmed that same year and she was flagship of the Superior Torpedo-Boat Command in 1904. [9] The ship was rebuilt between 1905 and 1907, her superstructure was enlarged and she was given two 4.7-inch (120 mm) guns, one each fore and aft, as well as four 6-inch guns in her waist, two per side. In 1909 she participated in the Hudson–Fulton Celebration along with the cruiser Etruria. [10] She served as a training ship after her rebuild until the start of World War I when she became the stationary flagship of the Commander-in-Chief in Taranto for the duration of the war. Etna was disarmed again in 1920 and sold for scrap in 1921. [2]

Stromboli, Vesuvio and Ettore Fieramosca participated in the 1893 Naval Maneuvers as part of the Squadron of Maneuvers. [11] Stomboli and Ettore Fieramosca next participated in the 1896 Naval Maneuvers as part of the Maneuver Fleet. [12] Stromboli was sent to the Far East in 1899 while Vesuvio and Ettore Fieramosca were sent there in 1900 to assist in putting down the Boxer Rebellion. [1] All three ships were assigned to the Cruising Squadron in Chinese waters in 1901. [13]

Stromboli returned to Italy in 1901 and was placed in reserve and served as an ammunition ship before being struck from the Navy List in 1907 and sold for scrap in 1911. After a second posting in the Far East, Vesuvio was placed in reserve, struck from the Navy List in 1911 and sold for scrap in 1915. Ettore Fieramosca returned to Italy and made a cruise off East Africa in 1905. She then sailed across the Atlantic and made a number of port visits in South America. The ship was then assigned to the American Squadron and refitted in Boston in November 1906. [14] Upon her return to Italy in 1909 Ettore Fieramosca was struck off the Navy List in July 1909 and sold. [3]

HMS Triumph, originally known as Libertad, was the second of the two Swiftsure-class pre-dreadnought battleships of the Royal Navy. The ship was ordered by the Chilean Navy, but she was purchased by the United Kingdom as part of ending the Argentine–Chilean naval arms race. Triumph was initially assigned to the Home Fleet and Channel Fleets before being transferred to the Mediterranean Fleet in 1909. The ship briefly rejoined the Home Fleet in 1912 before she was transferred abroad to the China Station in 1913. Triumph participated in the hunt for the German East Asia Squadron of Maximilian Graf von Spee and in the campaign against the German colony at Qingdao, China early in World War I. The ship was transferred to the Mediterranean in early 1915 to participate in the Dardanelles Campaign against the Ottoman Empire. She was torpedoed and sunk off Gaba Tepe by the German submarine U-21 on 25 May 1915.

Mikasa (三笠) is a pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the late 1890s, and is the only ship of her class. Named after Mount Mikasa in Nara, Japan, the ship served as the flagship of Vice Admiral Tōgō Heihachirō throughout the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur on the second day of the war and the Battles of the Yellow Sea and Tsushima. Days after the end of the war, Mikasa's magazine accidentally exploded and sank the ship. She was salvaged and her repairs took over two years to complete. Afterwards, the ship served as a coast-defence ship during World War I and supported Japanese forces during the Siberian Intervention in the Russian Civil War.

Japanese battleship <i>Asahi</i> Battleship of the Imperial Japanese Navy

Asahi was a pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the late 1890s. As Japan lacked the industrial capacity to build such warships itself, the ship was designed and built in the United Kingdom. Shortly after her arrival in Japan, she became flagship of the Standing Fleet, the IJN's primary combat fleet. She participated in every major naval battle of the Russo-Japanese War of 1904–1905 and was lightly damaged during the Battle of the Yellow Sea and the Battle of Tsushima. Asahi saw no combat during World War I, although the ship participated in the Siberian Intervention in 1918.

<i>Bayan</i>-class cruiser Class of Russian armored cruisers

The Bayan class was a group of four armored cruisers built for the Imperial Russian Navy around the beginning of the 20th century. Two of the ships were built in France, as Russian shipyards had no spare capacity. The lead ship, Bayan, was built several years earlier than the later three. The ship participated in several of the early naval battles of the Russo-Japanese War of 1904–05, and provided naval gunfire support for the Imperial Russian Army until she struck a mine. Bayan was trapped in harbor during the subsequent Siege of Port Arthur, and was sunk by Japanese artillery. She was salvaged and put into service with the Imperial Japanese Navy with the name of Aso. She mostly served as a training ship before she was converted into a minelayer in 1920. The ship was sunk as a target in 1932.

Shikishima fought in the Battles of the Yellow Sea and Tsushima and was lightly damaged in the latter action, although shells prematurely exploded in the barrels of her main guns in each battle. The ship was reclassified as a coast defence ship in 1921 and served as a training ship for the rest of her career. She was disarmed and hulked in 1923 and finally broken up for scrap in 1948.

<i>Katori</i>-class battleship Imperial Japanese Navys Katori-class of pre-dreadnought battleships

The Katori class was a two-ship class of pre-dreadnought battleships built for the Imperial Japanese Navy (IJN) in the early 1900s. As Japan lacked the industrial capacity to build such warships itself, they were designed and built in the UK. They were the last pre-dreadnought battleships to be built for Japan at overseas shipyards, and the last to be equipped with a ram. The ships were delivered after the end of the Russo-Japanese War of 1904–1905. They saw no action during World War I, although both were present when Japan joined the Siberian Intervention in 1918. They were disarmed and scrapped in 1923–1925 in accordance with the terms of the Washington Naval Treaty of 1922.

The Russian ironclad Kniaz Pozharsky was an iron-hulled armored frigate built for the Imperial Russian Navy during the 1860s. She was the first Russian armored ship to leave European waters when she cruised the Pacific Ocean in 1873–75. The ship did not participate in the Russo-Turkish War of 1877–78, and remained in the Baltic Sea until 1879–80, when she made another cruise to the Pacific. Kniaz Pozharsky was assigned to the Baltic Fleet for the rest of her career. She mainly served as a training ship after her refit in 1885 until she was hulked in 1909 and probably scrapped in 1911.

<i>Warrior</i>-class cruiser Royal Navys Warrior-class of four armoured cruisers

The Warrior class consisted of four armoured cruisers built for the Royal Navy in the first decade of the 20th century. After commissioning, all four sister ships were assigned to the Channel and Home Fleets until 1913 when Warrior was transferred to the Mediterranean Fleet. After the start of World War I in August 1914, Warrior participated in the pursuit of the German battlecruiser SMS Goeben and light cruiser SMS Breslau and her three sisters were assigned to the 2nd Cruiser Squadron of the Grand Fleet. Warrior joined the 1st Cruiser Squadron of the Grand Fleet in late 1914. Neither squadron participated in any of the naval battles in the North Sea in 1915. Natal was destroyed by a magazine explosion in late 1915 and only two of the ships participated in the Battle of Jutland in 1916. Cochrane was not engaged during the battle, but Warrior was heavily damaged and sank the following morning.

Italian cruiser <i>Piemonte</i> Protected cruiser of the Italian Royal Navy

Piemonte was a unique protected cruiser built for the Italian Regia Marina in the 1880s by the British shipyard Armstrong Whitworth. She was the first major warship armed entirely with quick-firing (QF) guns and she was also the fastest cruiser in the world upon her completion in 1889. Piemonte was frequently deployed overseas, including a lengthy tour in East Asian waters from 1901 to 1904. She saw significant action during the Italo-Turkish War in 1911–1912 in the Red Sea, where she frequently bombarded Ottoman ports. During the Battle of Kunfuda Bay in January 1912, she and two destroyers sank four Ottoman gunboats and forced ashore three more. Piemonte participated in World War I but she saw little action during the conflict. She remained in service until 1920, when she was scrapped.

Italian cruiser <i>Etna</i> Protected cruiser of the Italian Royal Navy

Etna was a protected cruiser of the Italian Regia Marina built in the 1880s. She was the lead ship of the Etna class, which included three sister ships. Named for Mount Etna on the island of Sicily, the ship was laid down in January 1883, was launched in September 1885, and was completed in December 1887. She was armed with a main battery of two 254 mm (10 in) and a secondary battery of six 152 mm (6 in) guns, and could steam at a speed of around 17 knots.

Italian cruiser <i>Stromboli</i> Protected cruiser of the Italian Royal Navy
