S-1

Construction, trials, and early service

S-1 entering port at an unknown location early in her career, approximately 1920 or 1921. On her forward deck is a protective cage over the three Y-tube transducers for her early passive sonar system. Just below that are the slab-sided fairings for her bow plane pivots, a characteristic feature of the Quincy built members of this class.

S-1 (right) and S-2 (SS-106) moored outboard of the submarine tender USS Beaver (AS-5) at New York City. The sign on the building in the background says "New York Central Line". The time frame is pretty tight as the S-2 was modified with a large, flared bow and a bow buoyancy tank soon after trials and this is missing in this photo. The S-1 was commissioned on June 5, 1920 and the S-2 on May 25, 1920 and the Beaver left July 22, 1921 for the Pacific with S-2 and others. That makes the date of this photo late summer 1920.

CDR Vincent John Moore was XO of the USS S-1 (SS-105) in 1921. He later became the CO of the USS R-9 (SS-86). He was a graduate of Annapolis, class of 1917. He served on board USS Pennsylvania (BB-38) when it went to Europe with President Wilson to sign the treaty ending WWI. CDR Moore retired from the Navy in 1924 due to health reasons. He was recalled to active duty in 1942 as an instructor. He passed away on December 9, 1973.

Notes

The dates of the testing below are in doubt. Even though they were taken from official USN sources (the Dictionary of American Naval Fighting Ships, aka DANFS), the webmasters are having a hard time believing that over 2½ years elapsed between the 1923 tests in Norfolk and the "first full cycle test" in 1926 in Groton. We believe that it is likely that the later date is in error, and the first full cycle test was actually sometime in 1924, vice 1926. It is possible that the dates are correct and that the Navy, for whatever reason, was just moving very slowly in the test series, but we find that unlikely. For now we will leave the dates as published, and if we find a correction we will publish it then.

This photo shows the beginning of the conversion work done to S-1 so that she could carry out the Navy's first, and as it turned out only, tests with launching an airplane from a submarine This is at the Portsmouth Navy Yard, Kittery, Maine in the late spring of 1923. The photo shows S-1 alongside the work pier, with O-8 maneuvering into the berth to the left. S-1 has had her aft superstructure removed in preparation to have the watertight aircraft storage cylinder installed. Work is also being done to her forward superstructure to remove the original 3"/23 caliber Mk 9 deck gun. In its place will be a foundation for and installation of a much more substantial 4"/50 caliber Mk 12 Mod 6 gun.

By the fall of 1923 the conversion work on S-1 was essentially complete and the Navy was eager to begin the initial aircraft testing. S-1 moved down to Naval Air Station Norfolk off Willoughby Bay in Norfolk, VA. There she conducted the earliest experiments with a Martin MS-1 floatplane on October 23, 1923. The plane would normally be stored in the hangar disassembled. It had to be pulled out and assembled, then the boat would submerge the after deck until it floated off. The pilot would then start the engine and make his take off run. After landing the process would be the reverse. From first breaking the surface to the airplane taking off took at least 30-40 minutes, and the process required a flat calm sea to do safely.

Note how much further down on the pressure hull the newly expanded aft superstructure extended, compared to the first photo above.

In the fourth photo S-1 has flooded down her after ballast tanks, submerging her stern. Note the crewmen walking on her after deck, up to their ankles in water. It appears that S-1 is trying to recover the MS-1 floatplane after a taxi or flight test.

These four photos were taken in late 1923 into early 1924 at a cold and snowy Portsmouth Navy Yard and show overhaul work being conducted on the aircraft cylinder, perhaps to correct problems revealed in the Norfolk tests. These photos give a good view of how the cylinder was arranged. The hemispherical door is hinged on the bottom and sealed to the cylinder by 11 individually bolted flanges. It proved to take an undesirable amount of time to open the door due to the bolted flanges. When open, the door swung downward into a recess in the deck, allowing the aircraft to be pulled out and assembled for flight.

Note the gunboat USS Wilmington (PG-8) moored in the background.

Aircraft testing continued quite slowly between late 1923 and the spring of 1926. It was a conservative testing program, and it may have been slowed by budgetary concerns as well. The first full cycle of surfacing, assembly, launching, retrieving, disassembly, and submergence actually did not take place until July 28, 1926 on the Thames River at New London.

Newspaper Photo Caption: THE FIRST SUBMARINE AIRPLANE IS TESTED OFF NEW LONDON
New London, Connecticut -- The United States Navy held the first tryout of the "Peanut Plane" off New London recently. It is a tiny three cylinder airplane installed in a waterproof casing on the deck of the U.S. submersible S-1 and can be launched in the short time of nine minutes. The plane weighs only 1000 pounds and is flown by the first "Submarine Pilot" LT Dolph C. Allen. Photo shows the plane completely assembled and ready for flight, which is launched by lowering the stern of the submarine. 9-2-26

It should be noted that the launching time of nine minutes was an initial estimate only. In actual practice it turned out to be more like 30-40 minutes in calm weather and good conditions.

This photo was taken shortly after the one above, with the S-1's forward deck completely clear of the water, but with the after deck still submerged.

This photo was taken just a few minutes after the one above, and shows details of the S-1's fairwater, bridge, and superstructure. This is not all of the S-1's crew, and they may have only been the men assigned to operate and maintain the airplane.

A series of four photos that show S-1 diving with a very brave camera man on top of the periscope shears! Location is unknown, but the date is approximately 1926.

S-1 firing a Mk 10 torpedo. Location and date unknown, but is probably mid to late 1920's. In the first photo you can see the torpedo streaking away from the boat after firing. The gyroscope in the weapon has turned it to its pre-programmed course. In the second photo the weapon has reached the end of its run and a burst of compressed air has blown ballast water out of the non-explosive practice warhead. In the third and fourth photos the weapon has surfaced and is being picked up by a torpedo retriever boat.
