Distilling SystemsUSS Bowfin (SS-287)Clean Water Fresh water is vital on board a submarine not only for drinking, cooking, and washing, but also for storage batteries, boilers, and as a cooling agent for the diesel engines. An American World War II submarine on a war patrol required a minimum of 600 gallons of fresh water a day. The majority of the water usage was for the batteries and cooking/cleaning. Beyond this, remaining water supplies should leave enough for each man in the crew to have a bath at least twice a week. Cooks were normally required to bathe every day, for obvious reasons. But the distiller units were very cantankerous and hard to keep operating when electrical power was reduced when submerged or if the unit became contaminated-a frequent problem. So water was limited. |
Secrets of the Sub
| Submarine Rescues |
Submarine RescuesA critical task performed by the US submarine force during World War II, was the rescuing of downed pilots and air crews; They were so efficient at it, that they rescued 520 US airmen from the Pacific Ocean waters. One of those rescued, went on to become President of the United States.
Former US President George H. W. Bush Sr. He was rescued by the USS Finback after being shot down while he was on an air strike mission over Chichi Shima in the Bonin Islands during 2 September 1944.
