SMS Szent István was an Austro-Hungarian dreadnought battleship, the only one operated wholly by the Hungarian part of the empire. Hungary got her battleship in return for agreeing to the immense funding of the Tegetthoff class, and named her after Hungary's first Christian king, Saint Stephen (Szent István in Hungarian).

Building

Szent István was laid down on January 29, 1912 at Ganz & Company's Danubius yard at Fiume, (the only large Hungarian shipyard), was launched on January 17, 1914, and not named Szent Istvan until December 13, 1915. This involved great expense, as the yard had hitherto only built relatively smaller merchant ships for, amongst others, Austrian Lloyd, and therefore had to be itself re-fitted for the building of larger vessels.

She differed from her three sister-ships in that she had a platform built around the fore funnel which extended from the bridge to the after funnel and on which several searchlights were installed. A further distinguishing feature was the modified ventilator trunk in front of the mainmast. She was the only ship of her class not to be fitted with torpedo nets.

Based at Pola she engaged in the usual patrols and bombardments along the Italian coast.

Sinking

At 3.30 a.m. on the morning of June 10, 1918, in the company of SMS Tegetthoff and seven other ships en route to attack the Otranto Barrage, Szent Istvan was hit by two 45 cm torpedoes launched from the Italian MAS-15 Motor Torpedo Boat under Corvette Captain Luigi Rizzo. Many of the 1,087 crew were asleep, getting rested for the battle expected in a few hours. Immediate chaos soon changed into frantic efforts to save the vessel which was rapidly shipping water. The Tegetthoff, which had at first sped away from the vicinity of the torpedo attack, returned and took the Szent Istvan in tow, in an attempt to reach the massive dry dock at Pula. However the pumps were unequal to the task before them and the ship continued to slowly list, sinking at 6.12 a.m. It is said she sank easily due to faults in the Tegetthoff class design: relatively low displacement and high centre of gravity, together with the tremendous weight of 12 × 305 mm main artillery. There were, however, only 89 dead, partly attributed to the fact that all sailors with the KuK had to learn to swim before entering active service.

There is film footage of the last half-hour of the Szent Istvan, taken by Lieutenant Mensburger from the Tegetthoff. The Szent István is one of only three battleships whose sinking was filmed, together with HMS Barham and USS Arizona. The Szent István film was later used to raise money for the Red Cross.
