HMS S1 was a British submarine built in 1914 based on an Italian design.
While on patrol in June 1915 the submarine's engines failed. The crew were able to capture the German fishing trawler Ost and used it to tow the submarine home.
The submarine was transferred to the Italian Royal Navy in October 1915.
