Armament

SM U-22 or U-XXII was a U-20-class submarine or U-boat built for and operated by the Austro-Hungarian Navy (German: Kaiserliche und Königliche Kriegsmarine or K.u.K. Kriegsmarine) during the First World War. The design for U-22 was based on submarines of the Royal Danish Navy's Havmanden class (three of which had been built in Austria-Hungary), and was largely obsolete by the beginning of the war.

U-22 was just over 127 feet (39 m) long and was armed with two bow torpedo tubes, a deck gun, and a machine gun. The submarine was laid down in mid 1915 and launched in January 1917. The still unfinished U-boat sank in the harbor at Fiume in June but was raised, repaired, and relaunched in October. After her commissioning in November, U-22 patrolled off the Po River estuary and, later, in the northern Adriatic out of Trieste.

After undergoing months of repairs for her failed electric motor in mid 1918, U-22 returned to duty and patrolled off the Montenegrin coast out of Cattaro in August. At Cattaro at the end of World War I, U-22 was ceded to France as a war reparation and scrapped in 1920. U-22 had no wartime successes.
