SM UB-13 was a German Type UB I submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The submarine was probably sunk by a British mine net in April 1916.
UB-13 was ordered in October 1914 and was laid down at the AG Weser shipyard in Bremen in November. UB-13 was a little under 28 metres (92 ft) in length and displaced between 127 and 141 tonnes (125 and 139 long tons), depending on whether surfaced or submerged. She carried two torpedoes for her two bow torpedo tubes and was also armed with a deck-mounted machine gun. UB-13 was broken into sections and shipped by rail to Antwerp for reassembly. She was launched in March 1915 and commissioned as SM UB-13 in April.[Note 1]
UB-13 spent her entire career in the Flanders Flotilla and sank 11 merchant ships, about half of them British fishing vessels. In March 1916, UB-13 was responsible for sinking the Dutch ocean liner Tubantia, raising the ire of the Dutch public. Tubantia was the largest neutral vessel sunk during the war and among the 30 largest ships sunk by U-boats. On 25 April 1916, UB-13 was sunk with all hands.
