The U-48 class was a class of four submarines or U-boats planned for the Austro-Hungarian Navy (German: Kaiserliche und Königliche Kriegsmarine or German: K.u.K. Kriegsmarine) during World War I. The design of the boats was based on plans purchased from the German firm AG Weser in January 1916. The Navy authorized Cantiere Navale Triestino to begin construction of the submarines in Pola in September 1916. Only two of the planned four boats were laid down, but neither of them was launched or completed. Both incomplete submarines were scrapped after the war ended.
