UB-12 was ordered in October 1914 and was laid down at the AG Weser shipyard in Bremen in November. UB-12 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-12 was broken into sections and shipped by rail to Antwerp for reassembly. She was launched and commissioned as SM UB-12 in March 1915.[Note 1]
UB-12 spent her entire career in the Flanders Flotilla and sank 22 ships, about half of them British fishing vessels. The U-boat was also responsible for sinking the British destroyer HMS Laforey in 1917. By early 1917, UB-12 had been converted into a minelayer with the replacement of her torpedo tubes with four mine chutes. UB-12 disappeared after 19 August 1918.
