What made this ship special when it was built?

This ship was famous for being one of the first in the world to use triple-gun turrets. These special turrets allowed the ship to carry more large cannons than most other battleships of its time. Because of this design, the ship was much stronger than older boats.

How did the ship help during World War I?

For most of the war, the ship stayed at its port in Pula. By just being there, it acted as a constant threat to enemy ships. This forced the Allied navies to keep a large blockade across the sea to watch the ship, which kept them very busy.

In late 1918, the ship was handed over to a new state as the empire fell apart. Before it could sail under its new flag, brave Italian divers snuck into the harbor. They attached a limpet mine to the hull, which sank the ship on November 1, 1918.

Why is this ship remembered in history?

People remember this ship as the very first dreadnought of the Austro-Hungarian fleet. It is also famous for the dramatic way it was destroyed during the final days of the war. Its sudden sinking serves as a major moment in naval history.

History

Built in Trieste, SMS Viribus Unitis was the first dreadnought battleship commissioned into the Austro-Hungarian fleet. It was famous for being one of the first warships ever equipped with triple-gun turrets.

During World War I, the ship stayed mainly in port at Pula to serve as a fleet-in-being. Its powerful presence forced Allied navies to maintain a continuous blockade across the Adriatic Sea.

In late 1918, as the empire collapsed, the warship was transferred to the newly formed South Slav state. Italian naval commandos sank it with a limpet mine before it could enter service under its new flag.
