SMS Zrínyi

SMS Zrínyi ("His Majesty's ship Zrínyi" [ˈzriːɲi]) was a Radetzky-class semi-dreadnought battleship (Schlachtschiff) of the Austro-Hungarian Navy (K.u.K. Kriegsmarine), named for the Zrinski, a Croatian-Hungarian noble family (Hungarian: Zrínyi). Zrínyi and her sisters, Erzherzog Franz Ferdinand and Radetzky, were the last pre-dreadnoughts built for the Austro-Hungarian Navy.

During World War I, Zrínyi saw action in the Adriatic Sea. She served with the Second Division of the Austro-Hungarian Navy's battleships and shelled Senigallia as part of the bombardment of the key seaport of Ancona, Italy, during May 1915. However, Allied control of the Strait of Otranto meant that the Austro-Hungarian Navy was effectively contained in the Adriatic. Nonetheless, the presence of the Zrínyi and other battleships tied down a substantial force of Allied ships.

With the war going against the Austrians by the end of 1918, Zrínyi was prepared for transfer to the new State of Slovenes, Croats and Serbs. On 10 November 1918, just one day before the end of the war, navy officers sailed the battleship out of Pola (Pula) and surrendered to a squadron of American submarine chasers. Following the handover to the United States Navy, she was briefly designated USS Zrínyi. In the Treaty of Saint-Germain-en-Laye, the transfer was not recognized; instead, Zrínyi was given to Italy and broken up for scrap.
