Isley BAP (R-1 Class Submarine) 1926

The R-class submarines were a class of United States Navy submarines active from 1918 until 1945. With the first of the class laid down following the American entry into World War I, they were built rapidly, but none were completed until after the Armistice.

The R-1 thru R-20 boats, designed by Electric Boat and built by Fore River Shipyard and Union Iron Works, were known as the "R-1 class" submarines . These single-hull boats were structurally very similar to the preceding O-class, but larger and therefore with more powerful machinery to maintain the required speed. For the first time in a US submarine class, 21-inch (533 mm) torpedo tubes were fitted, a tube diameter that is still standard worldwide. A more powerful fixed 3 inch (76 mm)/50 caliber deck gun replaced the retractable 3"/23 caliber gun found on previous classes.

Following the decommissioning of two Labeuf Class submarines the Peruvian Navy ordered 4 boats from US Electric Boat Co. Groton. A contract was signed in 1924 for the first two 755 ton submarines of the R-Class (R-1 and R-2) and later followed on R-3 and R-4.

Electric Boat built four "R Class" 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.

Dew to technical deterioration and maintenance problems it was decided on November 29, 1958 to put the boats out of service. In 1960 the BAP Isley was taken out of service.
