HNoMS Otra was an
Otra-class minesweeper built in 1939 for the
Royal Norwegian Navy. Captured by the Germans during the 1940 invasion of Norway and renamed
Togo, she was returned to the Norwegians in 1946.
Otra remained in service until being sold for scrapping in 1963.
Otra and her sister ship
Rauma were two purpose-built minesweepers constructed at
Nylands Verksted in
Oslo. Both ships were completed and commissioned only a short time before the
German invasion of Norway. The Otra class vessels used the
Oropesa system of mine sweeping. As the threat of war in
Europe became ever more clear the decision was made to improve the
Royal Norwegian Navy's mine warfare capabilities. At first a number of 2. class gunboats were rebuilt into
minelayers and
mine sweepers, but with war looming it soon became clear that more capable vessels were required.
