List of Austro-Hungarian U-boats

The Austro-Hungarian U-boat fleet during the First World War mainly consisted of German manufactured units transported by rail from Germany's northern shipyards to the Austrian ports on the Adriatic Sea. They served throughout the war against Italian, French and British shipping in the Mediterranean Sea with some success, losing eight of the twenty eight boats in service in return. Following the end of the war in 1918, all Austrian submarines were surrendered to the Entente powers, who disposed of them individually. There have never been any Austrian or Hungarian submarines since the war, as both, Austria and Hungary became landlocked.

According to "Jane's Fighting Ships of World War One", Austrian submarines were numbered in the same manner as German U-boats, with the prefix U for "Unterseeboot" followed by a production number. Unlike the German system however, Austrian boats used Roman numerals rather than the Arabic numerals used by the Germans to signify the numbering of their submarines. The numbers do not run in sequence, because a number of Austrian boats were pre-purchased by the German Navy after completion, or were never completed at their German shipyards.
