In Memoriam - USS G-2 (SS-27) - July 30, 1919
This very early submarine was designed in the late 1900s, with construction starting in 1909. Originally named USS Tuna, her name was changed prior to commissioning (all named US submarines were given letter and number designations on 17 November 1911, and this practice continued until just before the start of World War II).
G-2 spent much of her time conducting exercises and training, as the exact role of submarines was still being studied. (G-2's maximum depth was less than 50 feet.)
During the First World War, G-2 was used as a training boat for the then newly established submarine school in Groton, CT. She did conduct several short war patrols, searching for reported German U-Boats.
She was decommissioned on April 2, 1919 and was scheduled to be used as a target for testing depth charges. While being used for that duty, she sank at her moorings near Niantic Bay, CT, killing three of her inspection crew. Too deep for the salvage technology of the day, she was left where she sank. In 1962, she was partially salvaged by the U.S. Navy, then allowed to re-sink at the same spot.
