This photo shows R-6 alongside the R-10 with her bow sticking up above the water and with her stern sunk to the bottom. The minesweeper USS Cardinal (AM-6) is standing by in the background.
A malfunction in one of her torpedo tubes interlock systems caused the inner and outer doors to be able to be opened at the same time. The startled crew escaped and one man seeing what was happening raced to the deck an chopped the mooring lines.
Electrician's Mate 2nd Class Frank A. Spalsbury and Seaman John E. Dreffien lost their lives during this sinking.
The combined efforts of the crews of the R-10 and the Cardinal sealed up the R-6 and pumped out the water. She was fully raised on October 13, 1921 and towed to the Mare Island Navy Yard for reconditioning. Surprisingly she had suffered little damage and after a thorough drying out and cleaning was put back into full service.

R-6 seen from the air, port side, somewhere in the Atlantic, 1940-1941. For the R-class it was normal to have the deck gun stowed in an aft pointing position. There was a bracket on the forward end of the fairwater that the barrel could be clamped to. The R-class was unusual in this respect. R-6 had sat in reserve with the mothball fleet in Philadelphia from 1931 to 1940, when the war conditions in Europe prompted the Navy to put the reserve O and R-class boats back into full service.

R-6 crew, 1944. Michael Raymond Gargano, Signalman 2nd Class, is fifth man from the right in the back row. This is the crew that did the early work on developing the first USN submarine snorkel. The fifth man from the left in front row is Ensign W. Bernard Carlson, Jr. He had served aboard the USS Crevalle (SS-291) before reporting to the R-6. As a side note it is interesting that Ensign Carlson's wife was also a commissioned Navy Officer who ran the Medical Technology Laboratory at Submarine Base New London during the war.
The crew photo was most likely taken at Christmas 1944 in or around New London/Groton at a place called "Polly's" that burned down in the late 40's or early 50's. There were numerous crew parties and photos taken there. When asked, locals can no longer tell you exactly where it was located.

R-6 topside watch. The view is looking forward. Photo taken August 1945 in Ft. Lauderdale, Florida during snorkel testing operations. The bow of the USS R-10 is seen to the left. If you compare the R-6 forward hatch with images of older hatches from the 20's and 30's you can see how the technology changed. This is a modern submarine hatch very similar to those used today.

R-6 heading to sea in August, 1945 for tests of the newly installed snorkel device. This device would allow the submarine to run its diesel engines while at periscope depth, giving it a significant tactical advantage by eliminating the need to surface to charge batteries. Unfortunately, the technology came to the U.S. too late to have any impact on the war effort. By the time a design had been adapted from the original Dutch drawings and testing had begun, the war in the Pacific had concluded. The snorkel would play a large role in post-war submarine operations, with nearly every USN submarine adapted to use one.

R-6 snorkel mast with Michael Gargano sitting on the engine exhaust, August 1945. The head valve of the snorkel can be seen above Gargano's head. The induction head valve was an extremely important part of the design. It had a round float attached to a lever arm. If the boat dipped to low or if a wave washed over the head valve, the float would shut a valve disk on top of the assembly and prevent water from being ingested into the engines, which is a very bad situation. The float valve was nearly directly copied from the original Dutch design, and it had been adopted by the Germans. USN testing showed that that design was not sensitive enough to close off for spray nor did it close tight enough. Leaks were commonplace. Iterative testing eventually led the USN to alter the design significantly. As adopted for operational use the head valve was pneumatically actuated by three electrodes paced evenly around the rim of the head valve opening. When one or more of the electrodes was touched by seawater it closed an electrical circuit that actuated a pneumatic valve that instantly closed the head valve tightly and firmly. Once the electrodes were clear of water the valve would release the air pressure and the valve would pop back open.

R-6 crew relaxing while in port at Fort Lauderdale, Florida, August, 1945. The war had just ended when this photo was taken and the men of our submarines could relax for the first time in three and a half years. The R-10 (SS-87) is moored alongside.

A photo taken just after the one above from a slightly different angle. More details of the R-10 can be seen. One crewman is sitting on a chair on the deck of the R-10. Fort Lauderdale, Florida, August, 1945.
