G-1 plans 1916

Plans for G-1, corrected to December 5, 1916. Unusually, there is a significant error on the title page of these plans. The boat is identified as Submarine Torpedo Boat No. 26. G-1 never carried this designation at any time during her career. When commissioned she was assigned submarine hull number 19½, and much later was redesignated as Submarine No. 20. Submarine No. 26 was actually assigned to the G-4. This mess in designations is indicative of the rather jumbled nature of the acquisition of this boat and the other G-class submarines, none of which the Navy really wanted.

These plans show G-1 after the removal of the trainable superstructure torpedo tubes. She did not have a traditional torpedo room. The breech doors of her tubes let into the battery/crews berthing space, with the reload torpedoes stowed on the deck. She had separate captain's and navigator's "turrets", and a conning tower above them. Her 14 foot dinghy (motor launch) was stowed upside down in a stowage locker under clamshell doors in her after superstructure.
