The Austro-Hungarian U-boat fleet was created in the decade prior to the First World War. They were built to a variety of designs, many under licence from Germany. 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. They were reinforced by the Imperial German Navy’s Pola Flotilla, mainly comprising coastal U-boats transported by rail from Germany's northern shipyards to the Austrian ports on the Adriatic Sea.

The three surviving boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in 1940. After Tarantini was sunk, Bagnolini and Giuliani were selected for conversion to "transport submarines" in order to exchange rare or irreplaceable trade goods with Japan. Cargo capacity of 160 tons reduced reserve buoyancy from between 20 and 25% to between 3.5 and 6%; and armament was reduced to defensive machine guns. They submarines saw action in the Second World War during which they collectively sunk 5 freighters and 1 light cruiser and were eventually either sunk or captured.
