It Headed To The Panama Canal
The U.S.S. R-12 was launched in 1919. It was known as a veteran of sorts and had been decommissioned from the Navy in 1932. After this, it joined the reserve fleet. As the threat of war loomed, it returned to active service in July 1940. The vessel then sailed for Naval Submarine Base New London at Groton and got a comprehensive overhaul. In October 1940, it was fully prepared for active duty. It was sent on its first mission, which was to patrol the Panama Canal. The following year, it was ordered to go back to New London and then cruise the waters of New England. After Pearl Harbor was attacked in December 1941, this vessel went back to the Panama Canal and stayed there for ten months.
