SS 161 44k This and the next photo were both taken during the S-51 (SS-162) salvage operation. The first one was taken on 5 July 1926, the day the S-51 was finally brought to the surface. The S-50 (SS-161) had just emptied her air banks into hoses that led down to the S-51. The air was used to empty the engine and motor rooms of water. The S-3 (SS-107) stood by with full air banks to take over the operation. The S-50 reported her air all gone. The S-3 maneuvered to get alongside her. (Sept. 1925). Photo originally appeared in Edward Ellsberg's 1929 book, On the Bottom which told the story of the S-51 salvage.

SS 161 114k The S-50 (SS-161) came alongside the repair ship Vestal (AR-4) for a divers rehearsal (Oct. 1925). The S-50 was being used as a diver training ship. Techniques for installing special salvage hatches on the S-51 (SS-162) were first practiced on the S-50 so that the divers could work out the procedures prior to getting into the water.
