The Norwegian government purchased four submarines that were almost completed in 1913 and received three of these before World War I. The fourth, A-5, was seized by German authorities at the outbreak of war and commissioned as SM UA. It was used for coastal protection and from 1916 as a training vessel in the Baltic Sea.[1]
All three A-class submarines were lost in the first week following the German invasion of Norway, one in combat and the other two through scuttling.
