SMS Szent István
SMS Szent István (His Majesty’s Ship Saint Stephen) was the last of four Tegetthoff-class dreadnought battleships built for the Austro-Hungarian Navy. She was built at the Ganz-Danubius shipyard in Fiume, where she was laid down in January 1912. Launched two years later in 1914, construction on Szent István was delayed due to the small shipyards in Fiume, and further delayed by the outbreak of World War I in July 1914. She was finally commissioned into the Austro-Hungarian Navy in December 1915.
She was armed with a main battery of twelve 30.5 cm (12.0 in) guns in four triple turrets,
Szent István was struck by two torpedoes launched from MAS-15 during an attack on the Otranto Barrage, capsizing roughly three hours later off the island of Premuda. She is the only battleship whose sinking was filmed during World War I.
