USS C-5 (SS-16) was one of five C-class submarines built for the United States Navy in the first decade of the 20th century. Description The C-class submarines were enlarged versions of the preceding B class, the first American submarines with two propeller shafts. They had a length of overall, a beam of and a mean draft of . They displaced on the surface and submerged. The C-class boats had a crew of 1 officer and 14 enlisted men. They had a diving depth of . For surface running, they were powered by two Craig gasoline engines, each driving one propeller shaft. When submerged each propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, the boats had a range of at and at submerged. The boats were armed with two 18 inch (450 mm) torpedo tubes in the bow. They carried two reloads, for a total of four torpedoes. Construction and career C-5 was laid down by Fore River Shipbuilding Company in Quincy, Massachusetts, under a subcontract from Electric Boat Company, as Snapper, making her the first ship of the United States Navy named for the snapper. Snapper was launched on 16 June 1908 sponsored by Ms. A. Nicoll, and commissioned on 2 February 1910 with Lieutenant Chester W. Nimitz in command. She was renamed C-5 on 17 November 1911 and given hull number "SS-16" in 1920. Service history Snapper fitted out at the Boston Navy Yard, then began three years of training and tests along the East Coast and in Chesapeake Bay. She ran experiments with radio, submarine signalling apparatus, different types of batteries, and other equipment, all of which has since become standard in submarines. She joined in Fleet maneuvers helping to develop submarine tactics in submerged attacks on combatant ships, and engaged in operations with airplanes in the infancy of naval aviation. Highlights of the period were the reviews of the Fleet by President of the United States William H. Taft and Secretary of the Navy George von L. Meyer in November 1911 and October 1912. On 20 May 1913, C-5 and her sisters of the First Group, Submarine Flotilla, Atlantic Fleet, commanded by Lieutenant (junior grade) R. S.
