United States R class submarine

The R-class submarines were a class of United States Navy submarines active from 1918 until 1945.

The R-1 thru R-20 boats built by Fore River Shipyard and Union Iron Works were known as the "R-1 class" subs. These single-hull submarines were structurally very similar to the preceding O-class, but with the addition of 21-inch torpedo tubes and a fixed (rather than retractable) gun mount.

Boats R-21 to R-27, which were slightly smaller and faster than the R-1s, were built by Lake Torpedo Boat and are sometimes regarded as a separate class, the "R-21 class." These featured a double-hull and had their diving planes more conventionally positioned fore and aft, but retained the characteristic wide stern and 18-inch torpedo tubes.

Electric Boat built four boats for the Peruvian Navy (R-1 to R-4). Built after World War I using materials assembled from cancelled S-class submarines, they were refitted in 1935 36 and 1955 56, and renamed Islay, Casma, Pacocha, and Arica in 1957. They were discarded in 1960.
