SMS Tegetthoff was the second of four Tegetthoff-class dreadnought battleships built for the Austro-Hungarian Navy. Tegetthoff was named for the 19th-century Austrian Admiral Wilhelm von Tegetthoff, most notable for defeating the Italian Regia Marina at the Battle of Lissa in 1866. The ship was armed with a main battery of twelve 30.5 cm (12.0 in) guns in four triple turrets. Constructed shortly before World War I, she was built at the Stabilimento Tecnico Triestino shipyard in Trieste, where she was laid down in September 1910 and launched in March 1912.
