HNLMS O 15

O 15 was a O 12-class submarine of the Royal Netherlands Navy that saw service during World War II. It was the only submarine of the O 12 class built by Wilton-Fijenoord of Rotterdam. It was one of many Dutch ships doing convoy duty during the Spanish Civil War. When World War II broke out O 15 was stationed in Curaçao. It returned to Europe and was based in Dundee, whence it patrolled the coast of Norway and accompanied convoys to Arkhangelsk. The sub survived World War II and was taken out of active duty just after the Japanese surrender. It was demolished in 1946 in Hendrik-Ido-Ambacht.
