USS G-1
Submarine · United States · Lost 1921 · Narragansett Bay & the Rhode Island Coast
An early U.S. Navy submarine, once the record-setting Seal, expended as a target in Narragansett Bay depth-charge tests in 1921.
The Vessel and Her Loss
Laid down in 1909 as Seal and renamed G-1 before commissioning in 1912, this Lake Torpedo Boat Company-designed submarine trained out of the Naval Torpedo Station in Narragansett Bay and set a record dive to 256 feet during acceptance trials. After service through the First World War era, she was decommissioned and stricken from the Navy list in 1920, then sunk as a target during depth-charge tests off Taylor's Point in Narragansett Bay on 21 June 1921.
