Design and Construction Notes

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)

Photo from the private collection of Ric Hedman.
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)

Photo from the private collection of Ric Hedman
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.

A fine bow view of S-14 and S-17 alongside at the Mare Island Navy Yard in Vallejo, CA., September 23, 1927. Very noticeable in this photo is the starboard side mounted anchor, the retracted bow diving planes, and the flared out deck sponson for the 4"/50 caliber Mk 9 deck gun.

S-30 through S-41 (EB design built at Bethlehem San Francisco)

Photo courtesy of the Naval History & Heritage Command.
Elements of Submarine Division 17 moored in a nest at Tsingtao, China, early 1930's. Left to right: S-36, S-39, S-32, S-37, and S-41. Tsingtao (now Qingdao), on the Yellow Sea, was a frequent port of call for Asiatic Fleet submarines in the pre-war years. The boats have only recently arrived from what is likely a division level exercise at sea, and the much anticipated liberty call had not yet been announced. The sailors are milling about topside, chatting with each other, trying to beat the oppressive heat below. This photo gives a good view of the 4"/50 caliber Mk 9 gun that these boats were equipped with, and unusually all of the guns are elevated skyward.

S-42 through S-47 (Modified EB design built at Bethlehem Quincy)

An outstanding photo of Submarine Division 19, July 28, 1928 at San Diego. Left to right: S-46, S-42, S-47, S-43, S-44, and S-45. A lot of very interesting details of these boats can be seen. The crews are all turned out in their dress blues, and if anyone can identify any of these sailors, please let us know.

S-48 through S-51 (Modified Government design built by Lake Torpedo Boat Company)

Official USN photo, a copy of which is in the private collection of Ric Hedman.
S-51 and S-50 maneuvering close alongside, somewhere in the Caribbean, spring of 1924. This group represented the final iteration of the Government S-boat design. They were longer and heavier, and were equipped with a stern torpedo tube. Unfortunately, they were slow divers with poor underwater maneuverability. Not well liked by the Navy, S-49 and S-50 were disposed of under the terms of the London Naval Treaty in 1930. S-51 had been lost in a collision in 1925. Only S-48 survived through WWII, and only because she had been extensively modified in an attempt to improve her performance.
