SMS Vulcano (subsequently renamed to German Vulkan, also Vulcan) was a paddle steamer[1] built for the Austro-Hungarian Navy in Venice and launched in 1843.

Vulcano and other Austrian vessels managed to escape capture, however most of their men deserted to the Venetian side, in many cases since non-Italian officers promised immediate discharges to their Italian sailors.

[9] In March 1848 Vulcano evacuated the personnel of the Austrian embassy from Naples, but the crew mutinied mid-route and attempted to direct the ship to Venice, however the ambassador Prince Felix of Schwarzenberg managed to restore order and direct the ship to Trieste.

[10] [11] Vulcano was part of squadron commanded by Captain Ludwig Kudriaffsky that blockaded Venice in April 1848.

Vulcan was refloated the next day with assistance from SMS Custoza (1848) and the Austrian steamships Curtatone and Dorotea.
