"Viribus Unitis" was soon followed by "Tegetthoff", the namesake of the class, on 14 July 1913. During her gunnery trials, a discharge from one of the main guns of "Tegetthoff" damaged the staterooms of the ship's officers. "Prinz Eugen" was commissioned on 8 July 1914, ten days after Archduke Franz Ferdinand's assassination in Sarajevo. Expansion of the Graz-Danubius shipyards in Fiume delayed the launching and christening of "Szent István" until 17 January 1914. Though it was customary for either the Emperor or his heir to be present at the launching of a major warship, Franz Joseph was too feeble and his heir, Franz Ferdinand, refused to be there due to his anti-Hungarian attitudes. Franz Joseph sent a telegram of congratulations to avoid controversy, and the ceremony was presided over by Archduchess Maria Theresa who launched it with the words: "Slip out and may the protection of the Almighty be with you on all your ways!" Also present at the ceremony was Hungarian Prime Minister Tisza, Minister of Finance János Teleszky, and Minister to the Imperial Court Stephan Burián von Rajecz. As the German cruiser had recently been refitted at Trieste, her officers also attended the ceremony.
