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?
Context: In the early 20th century, the Greek Navy embarked on an expansion program to counter a strengthening of Greece's traditional rival, the Ottoman Empire.  The Ottomans ordered a new dreadnought battleship, "Reşadiye" ; in response, Greece ordered the dreadnought "Salamis" from a German shipyard.  The Ottomans acquired the ex-Brazilian "Rio de Janeiro" and renamed her "Sultân Osmân-ı Evvel" .  Greece responded with a second battleship ordered in France, "Vasilefs Konstantinos", built to the same design as the French "Bretagne" class .  As the Ottomans had a significant head start in battleship construction, the Greek Navy purchased two obsolete American pre-dreadnoughts—USS "Mississippi" and "Idaho" —as a stop-gap measure in June 1914.  The ships were renamed "Kilkis" and "Lemnos" , respectively. 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. SMS "Tegetthoff"  was an Austro-Hungarian dreadnought battleship of the "Tegetthoff" class named after Wilhelm von Tegetthoff, a 19th-century Austrian admiral most notable for defeating the Italian Navy in the Battle of Lissa. SMS "Baden" was a "Bayern"-class dreadnought battleship of the German Imperial Navy built during World War I.  Launched in October 1915 and completed in March 1917, she was the last battleship completed for use in the war; two of her sisters—"Sachsen" and "Württemberg"—were incomplete when the war ended.  The ship mounted eight 38 cm guns in four twin turrets, displaced 32200 MT at full combat load, and had a top speed of 21 kn .  Along with her sister "Bayern" , "Baden" was the largest and most powerfully armed battleship built by the Imperial Navy. SMS "Prinz Eugen"  was an Austro-Hungarian dreadnought battleship of the "Tegetthoff" class .  "Prinz Eugen" was built at the Stabilimento Tecnico Triestino yard, Trieste.  During World War I, "Prinz Eugen" supported the escape of  and  as well as the bombardment of Ancona. 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". HMS "Audacious" was the fourth and last "King George V"-class dreadnought battleship built for the Royal Navy in the early 1910s.  After completion in 1913, she spent her entire career assigned to the Home and Grand Fleets.  She was sunk by a German naval mine off the northern coast of County Donegal in Ulster, Ireland, in October 1914. 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. Raid on Pula was a maritime raid undertaken on 1 November 1918 during the end of World War I.  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. HMS "Erin was a dreadnought battleship of the Royal Navy which was originally built in response to an order placed by the Ottoman government with the British Vickers company.  She was intended, when accepted for service in the Ottoman Navy, to be named Reşadiye", as the first of two "Reşadiye"-class battleship s.  The Ottoman intention was to procure a battleship which was at least the equal of any other ship currently afloat or building.  The design was based on that of "King George V" , but with some features of "Iron Duke" .  In August 1914, when the First World War broke out, the ship was nearly completed; but at the orders of Winston Churchill, the First Lord of the Admiralty, she was seized (together with another dreadnought battleship under construction in Britain for the Ottoman Navy, "Sultan Osman I", which was renamed as HMS "Agincourt" ) for use by the Royal Navy.
