On 10 September, "Torsk" sailed from the Marianas, bound for Pearl Harbor. From there, she proceeded to the Panama Canal, sailed into the Atlantic and ultimately arrived in New London, Connecticut in mid-October. This was her home port for the next seven years, during which time she served primarily as a training ship. She was also involved with various tests and training exercises. The submarine was also used for Navy Reserve training cruises. She was assigned to Submarine Squadron 2 in June 1949 and in mid-1950 she was sent on a deployment to the Mediterranean Sea. She returned to New London later in the year for fleet maneuvers. In 1951, her training operations took her to the Caribbean Sea.
