I grew up as a “Navy Brat”. For those not familiar with the term it refers to those children who grew up with a parent that served in the Navy. This same “brat” designation applies to each branch of the service, but, I believe it is closer to the truth with those in the Navy. This, in part, is due to the fact that our dad would leave for numerous months at a time plus our Dad had to deal with us alone. Then, she would come house plus try to change everything. This led to some rather rebellious attitudes for sure. As every one of us got older, our sister started asking more questions about our dad’s job. Dad was stationed on a submarine plus life was actually strange there. They would sometimes not surface for thirty days at a time plus our sister had all sorts of questions on how that worked. She wondered how they ate, slept, got clean water, plus even fresh air. These were honest questions for sure. The a single that interested myself and others was how they had fresh air to breathe. Dad explained that they depended heavily on the air filtration, oxygenator, plus Heating plus Air Conditioning systems on board to ensure that they were breathing the right ratio of air. If any of the Heating plus Air Conditioning, filtration, or air quality systems are not laboring correctly the sub would have to surface to drawn in fresh air. This could be a dire security issue as it would supply away their position to anyone who wanted to know. My dad worked as a cook on the submarine so she was genuinely grateful to the electricians plus Heating plus Air Conditioning servicemens on board that kept them healthy plus safe while submerged for those long days.
