Project history: The further development of R class submarines. They were built under three notably differed designs developed by Holland, Lake and Bureau of construction. After the acquisition of these designs by General board in 1917 one submarine was built under each of them as "prototype" (S1, 2 and 3 respectively). Lake variant (S2) appeared unsuccessful, and later Lake built submarines under Bureau design.
Modernizations: none.
Naval service: No significant events.
