G-class

Design, Construction, and Naming Notes

The four G-class submarines were not actually a class at all. They were built to four completely different designs, but they were intended to have similar military characteristics, so they were grouped together. They were named Seal, Tuna, Turbot, and Thrasher when ordered, but their names were all changed to the G-class names on November 17, 1911, well before any of them had been commissioned. G-1 and G-2 were of a related Lake Torpedo Boat Co. design and were built by the Newport News Shipbuilding & Drydock Co. in Newport News, VA. G-3 was of a modified Lake design whose construction was started at the Lake company yard in Bridgeport, CT. Lake ran into severe financial difficulties and declared bankruptcy, so G-3 had to be towed to the New York Navy Yard for completion. G-4 was an ill-advised attempt to introduce competition to the submarine acquisition process, being built to the Italian Laurenti design at William Cramp & Sons Shipbuilding Co. in Philadelphia, PA. None of these boats were considered successful, spending an average of just six years in service before being decommissioned and disposed of.

G-1 represents a unique anomaly in the USN. Her development and construction was so troubled that the Navy was very unsure if they would even accept it. When it did eventually pass acceptance trials, the Navy awkwardly assigned it hull number 19½, the only time in its entire history that the Navy assigned half a hull number to a commissioned warship. When the USS F-1 (Submarine No. 20) was lost in a collision, the Navy took another unprecedented step and reassigned the F-1's hull number to G-1! She was eventually redesignated in the SS series, but not long after she was disposed of as a depth charge target

Submarine Seal, February 8, 1911.

Simon Lake's submarine Seal is shown here shortly after her launch from Newport News Shipbuilding, Virginia on February 8, 1911. It would be nearly another two years before she was commissioned into the United States Navy, and then only reluctantly. During this fitting out period her name was changed to G-1.
