Austro-Hungarian Battleship Radetzky
 
Austro-Hungarian Battleship Radetzky
Country: Austria-Hungary
Type: Battleship
Service: 1908 - 1918
Ships in class: 3

The Radetzky class were pre-dreadnought battleships built for the Austro-Hungarian Navy between 1907 and 1910. All ships were built by the STT shipyard in Trieste. The class saw limited action during World War I. At the end of the war in 1918, Austria intended to transfer her entire fleet to Yugoslavia in order to keep it out of Italian hands. However, under the subsequent peace treaty, the Yugoslavs were not able to keep the battleships, and all three were broken up in Italy in 1920.

Radetzky class battleships: Erzherzog Franz Ferdinand; Radetzky; Zrinyi.
