The G-1 design had been approved by early 1909 and the keel was laid on 2-2-09. The completed vessel was christened by Simon Lake’s daughter, Margaret, and launched Feb. 8, 1911. She was commissioned on 10-28-12 and was commanded by LT Kenneth Whiting until 3-6-20.
The success of the G1 led to five additional submarine boats contracts with the U. S. Government, including the G-2 (The Tuna) and the G-3 ( The Turbot).
