Submarine M‑1 (SS‑47) was laid down 2 July 1914 by Fore River Shipbuilding Co., Quincy, Mass., for Electric Boat Co., New York, N.Y.; launched 14 September 1915; sponsored by Miss Sara Dean Roberts; commissioned 16 February 1918; Lt. Cmdr. M. R. Pierce in command.
Following commissioning, M‑1 was assigned to Submarine Division 2, and was home ported at Newport, R.I. For the next 3 years, she operated off the east coast, providing training for the new generation of submariners who would contribute to the defeat of the Japanese Navy in World War II. During her last year of active service, she was under the operational control of SubDiv 5 and SubDiv 3.
The submarine was decommissioned at Philadelphia Naval Shipyard 15 March 1922, stricken from the Navy list the following day, and was sold for scrap 25 September 1922 to J. G. Hitner, Philadelphia, Pa.
