SMS Kronprinz Erzherzog Rudolf was a unique ironclad warship built for the Austro-Hungarian Navy in the 1880s, the fleet's last vessel of that type. The ship was laid down in January 1884, launched in July 1887, and completed in September 1889. She was armed with a main battery of three 30.5-centimeter (12 in) guns and had compound steel plating of the same thickness on her armored belt. The ship had an uneventful career, in large part due to her rapid obsolescence. She made trips to foreign countries to represent Austria-Hungary, but was reduced to a coastal defense ship by 1906. She continued in this role through World War I, based at Cattaro Bay, where her crew took part in the Cattaro Mutiny in early 1918. After the war, Kronprinz Erzherzog Rudolf was transferred to the Navy of the Kingdom of Serbs, Croats and Slovenes, renamed Kumbor and classed as a coastal defence ship, but she remained in their inventory for only a year, being sold for scrap in 1922.
