USS Sargo (SS-188)
USS ''Sargo'' (SS-188), the lead ship of her class of submarine, was the first ship of the United States Navy to be named for the sargo.
Her keel was laid on 12 May 1937 by the Electric Boat Company in Groton, Connecticut. She was launched on 6 June 1938 sponsored by Mrs. Catherine V. Nimitz, wife of Captain Chester W. Nimitz, and commissioned on 7 February 1939, Lieutenant E. E. Yeomans in command.
==Sargo batteries==
''Sargo'' was the first vessel equipped with a new lead-acid battery designed by the Bureau of Steam Engineering (BuEng) to resist battle damage, based on a suggestion by her commissioning commanding officer, Lieutenant E. E. Yeomans.〔Friedman, p. 265〕 It quickly became known as the "Sargo battery". Instead of a single hard rubber case, it had two concentric hard rubber cases with a layer of soft rubber between them. This was to prevent sulfuric acid leakage in the event one case cracked during depth-charging.〔(The Pacific War Online Encyclopedia, ''Sargo''-class article )〕 This remained the standard battery design until replaced with Sargo II and GUPPY batteries in submarines upgraded under the Greater Underwater Propulsion Power Program after World War II. Each battery's capacity was slightly increased by installing 126 cells instead of 120; this also raised the nominal voltage from 250 volts to 270 volts, which has been standard in US usage ever since, including the backup batteries of nuclear submarines.
