The S-class submarines were built to five distinctly different designs with several variations at four different shipyards. The designs were from the Electric Boat Company (EB) of New York City (later Groton, CT.), the Lake Torpedo Boat Company (LTB) of Bridgeport, CT., and the Portsmouth Navy Yard in Kittery, ME. While similar in military and operational capability, the various designs were vastly different in installed equipment, interior arrangement, and external appearance. For further information, see the Visual Guide articles here.
The class is broken down by groups below.
S-1 and S-18 through S-29 (EB design built at Bethlehem Quincy)

Elements of Submarine Division 4 alongside the pier at Coco Solo, Panama, March or April 1927. Not all of the boats can be positively identified. Left to right: S-19, possibly S-18, S-27, S-1, S-22, and unknown. All of the boats have their T-shaped radio mast raised, with aerial wires running from the mast down to the bow and stern. These long wires provided long range communication.
S-2 (Lake design built at Lake Torpedo Boat Company)

S-2 while on sea trials in 1919, prior to commissioning. S-2's bow planes retracted into the superstructure horizontally, the EB design had the bow planes retracting at an angle. Trials showed that she had the tendency to burrow into the waves due to a lack of buoyancy forward. S-2's bow would be soon modified with an additional bow buoyancy tank, giving her a distinctive humped appearance. Her chariot style bridge fairwater has not yet been added. S-2 does not have a deck gun installed in this photo. She would later have a 4"/50 caliber Mk 9 gun installed forward, requiring the installation of a large deck sponson around the gun.
S-3 through S-9 (Government design built at Portsmouth Navy Yard)

A portion of Submarine Division 12, consisting of S-4, S-8, S-6, and S-9 alongside the pier at Coco Solo, Panama, March or April, 1927. S-4 would be lost in a tragic accident off Provincetown, MA. just eight months later.
S-10 through S-13 (Modified Government design built at Portsmouth Navy Yard)
Photo courtesy of the Naval History & Heritage Command.
S-13, S-10, and S-12 moored alongside the Balboa Docks, Panama, approximately 1935. Temporary canvas awnings have been erected forward of the conning tower fairwaters in an attempt to ward off the tropical heat. These boats did not have air conditioning. They all have received the safety modifications enacted after the S-4 sinking. The forward rescue buoys can be seen on the starboard side, just forward of the boat's name. They are painted black, a force wide effort that began in 1934. Previously all USN submarines were the standard battleship gray.
