context_page_description: SMS Viribus Unitis was an Austro-Hungarian dreadnought battleship, the first of the Tegetthoff class. "Viribus Unitis", meaning "With United Forces", was the personal motto of Emperor Franz Joseph I.
  Viribus Unitis was ordered by the Austro-Hungarian Navy in 1908 and was laid down in Stabilimento Tecnico Triestino shipyard in Trieste on 24 July 1910. Viribus Unitis was launched from the shipyard on 24 June 1911 and was formally commissioned into the Austro-Hungarian Navy on 5 December 1912.
  During World War I, Viribus Unitis took part in the flight of the German warships SMS Goeben and Breslau. In May 1915, she also took part in the bombardment of the Italian port city of Ancona. Viribus Unitis was sunk while at anchor by a limpet mine planted by Raffaele Rossetti, an Italian engineer and naval officer of the Regia Marina, and Raffaele Paolucci, an Italian surgeon and naval officer, on 1 November 1918.
