The British S class submarine of 1914 (not to be confused with the British S class submarine (1931) built during pre World War 2 and World War 2) were built by Scotts, Greenock just before World War 1. The S class was based on an Italian design of the Laurenti boats.

3 vessels were constructed and all 3 were transferred to the Italian Navy in October 1915 presumably on the grounds that the Italians would be more familiar with the design and technology.
