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. Note the retracted wheels under the keel and the diving compartment near the torpedo tubes, the last time these unorthodox features would appear in a Lake submarine that was purchased by the USN.
