S-1 sliding down the ways at the Bethlehem Quincy shipyard (formerly Fore River Shipbuilding), Quincy, MA. on October 26, 1918. The tube at the tip of the bow is a towing fairlead hawsepipe. The two port side torpedo tube shutter doors can be seen, and at the bottom underneath the retracted bow planes is the boat's mushroom anchor. Despite flying the U.S. flag on the aft flagstaff, the boat is not yet in commission, and would not be until June 5, 1920.
S-18 moored to the Electric Boat owned engine repair barge Isaac L. Rice in the Thames River at Groton, CT., June 2, 1922. This was a frustrating time for the S-18. She had been launched on April 29, 1920 from the Bethlehem Quincy shipyard in Quincy, MA., and during the fitting out phase it was found that the NELSECO 8-EB-15 engines that had been installed had very serious problems that prevented them from being run at high speeds. The Navy refused to accept the boat until a fix had been made, so S-18 was sailed up to Groton by EB personnel and moored to the Isaac L. Rice where her engines were rebuilt. Finally, nearly four years after being launched, S-18 was commissioned into the U.S. Navy on April 3, 1924. All of the Electric Boat design S-boats were affected by the engine problems, greatly delaying their entry into USN service. See the article at this link for the details.

Starboard side view of S-19 sailing along the Thames River, CT., circa 1924. Note that the S-19 has rounded fairings around her bow plane pivots, a marked contrast to the other S-boats of the Quincy group, which all had angular slab sided fairings.
S-29 maneuvering up to moor, probably alongside a tender in the mid 1920's. Location is unknown but is probably San Diego. The photo was taken prior to the safety reforms brought on by the S-4 disaster in 1927, as the aft superstructure skeg near the rudder is still in place. By the time of this photo, the earlier Y-tube deck sonar array had been replaced by the trainable T-shaped SC array, shown here between the flagstaff and the open hatch to the torpedo room. The SC was the first sonar array that was capable of giving a reasonably accurate bearing to the target.
