S90-class torpedo boat

The S90 class of torpedo boats was a group of large torpedo boats built for the German Imperial Navy (Kaiserliche Marine) in the early 20th century. They were Hochsee-Torpedoboot ("High seas torpedo boat") built to varying designs by Schichau at Elbing (36 vessels) and Germaniawerft at Kiel (12 vessels). German torpedo boats were designated by shipbuilder, with the first letter of their designation reflecting their builder.
