SMS Wien

SMS Wien circa 1898

After her commissioning, Wien took part in Queen Victoria's Diamond Jubilee International Fleet Review at Spithead on 26 June 1897, as well as an international blockade of Crete during the Greco-Turkish War of 1897. She was back at Pola on 16 April 1898. Wien and her sisters formed the Navy's 1st Capital Ship Division (I. Schwere Division) in 1899 and the division made a training cruise to the Eastern Mediterranean where they made port visits in Greece, Lebanon, Turkey and Malta later that year. In early 1902 they made another training cruise to the Western Mediterranean with port visits in Algeria, Spain, France, Italy, Corfu, and Albania. The ship was fitted with a Siemens-Braun radio early the following year. The ships of the division were inspected by Archduke Franz Ferdinand, the heir to the throne, in March 1903 at Gravosa. Shortly afterwards, Wien, Budapest, the battleship Habsburg and the destroyer Magnet made a cruise to the Eastern Mediterranean. Wien served as flagship of the division until she was posted at Salonica, Greece on 13 May to support Austro-Hungarian interests there after several terrorist acts against Austro-Hungarian citizens. She returned to Pola on 10 June and resumed her assignment as flagship. In 1904, the Monarch-class ships formed the 2nd Capital Ship Division[10] and they took part in the 1904 cruise of the Adriatic and Mediterranean Seas as well as training exercises in which the three Habsburg-class battleships engaged the Budapest and her sisters in simulated combat. Those maneuvers marked the first time two homogeneous squadrons consisting of modern battleships operated in the Austro-Hungarian Navy.[11] In 1905, Wien made a cruise of the Levant and visited ports in Greece, Turkey, Egypt and Albania. Later that summer, the ship ran aground during a night exercise off Meleda Island; it took two tries by Budapest and Habsburg to pull her off. She had to be dry-docked for repairs.[12]

The Monarchs were relegated to the newly formed Reserve Squadron on 1 January 1906 and were only recommissioned for the annual summer exercises. They participated in a fleet review by Archduke Franz Ferdinand in September conducted in the Koločepski Channel near Šipan. The ships were briefly recommissioned at the beginning of 1913 as the 4th Division after the start of the Second Balkan War, but were decommissioned again on 10 March.[13]

With the beginning of World War I the three Monarchs were recommissioned as the 5th Division. They were sent down to the Cattaro in August 1914 to attack Montenegrin artillery batteries on Mount Lovćen bombarding the Austro-Hungarian naval base at Cattaro and the fortifications defending it. Budapest and her sisters arrived on 13 August, but their guns could not elevate sufficiently enough to engage all of the enemy artillery, which was reinforced by eight French guns on 19 October. The battleship Radetzky was summoned to deal with the guns two days later and she managed to knock out several French guns and forced the others to be withdrawn by 27 October. The Monarchs remained at Cattaro until mid-1917 to deter any further attacks. In August, Budapest and Wien were transferred to Trieste to serve as guard ships against Italian commando raids. Each ship was fitted with an anti-aircraft gun after their arrival on 26 August to counter constant Italian air attacks. Wien was damaged by a near miss on 5 September and both ships withdrew to Pola on 12 September.[14]

They returned to Trieste on 30 October[6] and sortied into the Gulf of Trieste on 16 November to attack Italian coastal defenses at Cortellazzo, near the mouth of the Piave River. Budapest and Wien opened fire at 10:35 at a range of about 9–10 kilometers (5.6–6.2 mi) and knocked out most of the Italian guns after about a half-hour. Their bombardment was interrupted by several unsuccessful Italian air attacks before a more coordinated attack was made by five MAS torpedo boats and five aircraft around 13:30. This was also unsuccessful and the last Italian coast defense gun was knocked out an hour later.[15] Wien was hit seven times in the superstructure and only lightly damaged;[6] none of her crewmen were wounded.[16]

Anxious to revenge themselves against the Austro-Hungarians, the Regia Marina (Royal Italian Navy) made plans for a sneak attack on the two ships in their berths in the Bay of Muggia, near Trieste, by MAS launches.[17] On the night of 9/10 December, two MAS boats managed to penetrate the harbor defenses undetected, and fired torpedoes at Wien and Budapest at 02:32. The torpedoes fired at Budapest missed, but Wien was hit by two torpedoes fired by MAS 9, commanded by Lieutenant (tenente di vascello) Luigi Rizzo, that blew a hole 10.5-meter (34 ft) wide abreast the boiler rooms.[18] All of the watertight doors were open on board the Wien and the ship capsized in five minutes despite an attempt to counter her growing list by flooding the trim tanks on the opposite side. The attack killed 46 members of the crew.[19] Both Italian boats escaped without being detected and Rizzo was awarded the Gold Medal of Military Valor.[6]

Wien was buried in the mud of the harbor bottom at a depth of 16.5 meters (54 ft) and salvage of the ship was ordered on 14 December. That same day the navy convened a court-martial of Vice Admiral Alfred Freiherr von Koudelka, commander of the naval district, the captains of both ships, and the commander of the naval defenses of Trieste. On 16 January 1918, the court convicted all four individuals for failing to take all possible precautions to protect the ships and failing to ensure that the precautions were taken. As punishment the court recommended that Koudelka and the two ship captains be retired and the commander of the naval defenses of Trieste to be returned to his former reserve status. Emperor Karl approved the recommendations on 23 January.[20]

The navy ordered that the salvage of Wien be stopped on 7 June and the wreck was ultimately salvaged by the Italians sometime during the 1920s. A section of the ship's stern is on display at the Museo Storico Navale in Venice.[21]
