Question: Which class was this Austro-Hungarian dreadnought battleship that was renamed to Jugoslavija and rigged with explosives and sunk near the end of World War I?

SMS "Viribus Unitis"  was an Austro-Hungarian dreadnought battleship, the first of the "Tegetthoff" class .  Its name, meaning ""With United Forces"", was the personal motto of Emperor Franz Joseph I. <SEP> The dreadnought was the predominant type of battleship in the early 20th century.  The first of its kind, the Royal Navy's "Dreadnought" , made such a strong impression on people's minds when launched in 1906 that similar battleships built subsequently were referred to generically as "dreadnoughts", and earlier battleships became known as "pre-dreadnoughts".  "Dreadnought"' s design had two revolutionary features: an "all-big-gun" armament scheme, with more heavy-calibre guns than previous ships, and steam turbine propulsion.  As dreadnoughts became a symbol of national power, the arrival of these new warships was a crucial catalyst in the intensifying naval arms race between the United Kingdom and Germany.  With the launch of a single ship, "Dreadnought", the scales of naval power were reset overnight.  As a result, dreadnought races sprang up around the world, including in South America, during the lead up to World War I.  Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era.  Within five years, new battleships had outclassed "Dreadnought".  These more powerful vessels were known as "super-dreadnoughts".  Most of the original dreadnoughts were scrapped after the end of World War I under the terms of the Washington Naval Treaty, but many of the newer super-dreadnoughts continued to be used throughout World War II.  The only surviving dreadnought is USS "Texas" , located near the San Jacinto Battleground State Historic Site. <SEP> The Yugoslav torpedo boat "T1 was a seagoing torpedo boat that was operated by the Royal Yugoslav Navy between 1921 and 1941.  Originally 76 T", a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1914, she was armed with two 66 mm guns and four 450 mm torpedo tubes, and could carry 10–12 naval mines.  She saw active service during World War I, performing convoy, escort and minesweeping tasks, anti-submarine operations and shore bombardment missions.  She was part of the escort force for the Austro-Hungarian dreadnought SMS "Szent István" during the action that resulted in the sinking of that ship by Italian torpedo boats in June 1918.  Following Austria-Hungary's defeat later that year, "76 T" was allocated to the Navy of the Kingdom of Serbs, Croats and Slovenes, which became the Royal Yugoslav Navy, and was renamed "T1". <SEP>  It was carried out by two officers of the Italian Regia Marina with the goal of damaging the Austro-Hungarian fleet anchored in the bay of Pula.  The fleet was handed by the Austrians to the newly established State of Slovenes, Croats and Serbs only a couple of hours before the raid, with Janko Vuković, previously an officer of the Austro-Hungarian navy, being declared the commander-in-chief of the new state's navy.  State of SHS, declared neutrality in the war and informed the Allies shortly after taking over armed forces on 31 October.  However, the attackers were not aware of this, and had rigged the main ship SMS Viribus Unitis (renamed to Jugoslavija) with explosives, which ended in the ship's sinking and the death of Vuković. Raid on Pula was a maritime raid undertaken on 1 November 1918 during the end of World War I.
