The two U-3-class boats, both launched in 1908, were just under 140 feet (43 m) long and were each powered by two kerosene two-stroke engines while surfaced, and two electric motors when submerged. The U-3 class initially had diving problems that were alleviated after several modifications to fins and diving planes. Both boats of the class served in combat during World War I. U-3, the lead boat of the class, was sunk by gunfire in August 1915. U-4 was the longest-serving Austro-Hungarian submarine and sank 14,928 gross register tons (GRT) and 7,345 tons of ships, including the Italian armored cruiser Giuseppe Garibaldi in July 1915. U-4 was handed over to France as a war reparation in 1920 and scrapped.
