Submarine Squadron 4 (also known as SUBRON 4 or CSS-4) was raised by the United States Navy in 1930. Since 9 July 1997, the squadron has been based at the Naval Submarine Base New London, Groton, Connecticut, United States of America.
In 1930, the squadron was raised at the Pearl Harbor submarine base. Its commanding officers to 1945 included the following captains:
It was Captain Freeland A. Daubin who was in command during the Japanese attack on Pearl Harbor on 7 December 1941.
On 13 January 1943, the command of Submarine Base Pearl Harbor and Submarine Squadron 4 were separated, due to the demands on each command by war time operations. As a result, Captain C. D. Edmunds relieved Captain J. H. Brown, Jr., as commanding officer of the submarine base. Captain Brown retained the command of the squadron. The commanding officer of the submarine base continued under the squadron commander until October 1945. At that time, the submarine force was reorganised and the base commander came directly under command of the Submarine Force, U.S. Pacific Fleet.
In about August 1945, the squadron began operations from Key West, Florida, as part of the U.S. Atlantic Fleet. Commanding officers at Key West were Captains Edward S. Hutchinson (October 1945 to 12 March 1947) and Lawrence Randall Daspit (12 March 1947 to 1949). In December 1947, during Daspit's command, President Harry Truman visited the base.
While at Key West, the squadron included USS Howard W. Gilmore (AS-16), and USS Petrel (ASR-14). Submarines assigned to the squadron included the USS Clamagore (SS-343) which was the squadron flagship from January 1946 to 1 August 1959. The USS Sea Poacher (SS-406) was with the squadron from 1 June 1949 to 20 October 1969. The USS Thornback (SS-418) joined the squadron on 2 October 1953. She remained until she was reassigned to the Charleston Naval Base in 1959. Other submarines were the USS Quillback (SS-424); USS Trumpetfish (SS-425) (1953); USS Medregal (SS-480), which joined after the end of World War II; the USS Requin (SS-481) (joined 6 January 1946); USS Irex (SS-482) (1945 to 1947); USS Odax (SS-484); and USS Amberjack (SS-522). The Amberjack arrived in January 1948, and operated along the East Coast and in the West Indies for 11 years.
