HNLMS O 12

Netherlands

HNLMS O 12 was the lead ship of her class of submarines built for the Royal Netherlands Navy during the 1930s for European service. Completed in 1931, the boat was being overhauled when Germany invaded the Netherlands in 1940 during the Second World War. She was scuttled by the Dutch to prevent her capture, but the boat was salvaged by Nazi Germany's Kriegsmarine and taken into service as UD-2 in 1943. After serving as a training boat, she was scuttled again by the Germans in May 1945.
