Two of the Tegetthoff-class battleships were commissioned less than two years prior the beginning of World War I, while Prinz Eugen was commissioned the same month as the assassination of Archduke Franz Ferdinand.
Dva bojna broda klase Tegetthoff stavljena su u službu manje od dvije godine prije početka Prvoga svjetskog rata, dok je Prinz Eugen stavljen u službu isti mjesec kad je ubijen nadvojvoda Franjo Ferdinand.
