SMS Prinz Eugen was the second member of the Kaiser Max class built for the Austrian Navy in the 1860s. Her keel was laid in October 1861 at the Stabilimento Tecnico Triestino shipyard; she was launched in June 1862, and was completed in March 1863. She carried her main battery—composed of sixteen 48-pounder guns and fifteen 24-pounders—in a traditional broadside arrangement, protected by an armored belt that was 110 mm (4.3 in) thick.
