What does it feel like to live in a pressurized metal tube, 1000 feet (300 m) under the ocean, and only steps away from lethally dangerous nuclear fissile material? Nuclear submariners know. In wartime, theirs is an unenviable task – to hunt other submarines and destroy them before they themselves can be hunted down. Nuclear power allows these submarines to operate at high speed for long durations without having to surface frequently. Nuclear submarines never need to be refueled throughout their 25-year life-span. This fascinating book looks at what life is like for the men who live and work together on these boats; what the inside of a nuclear submarine looks like and how it works; how the sea gives the submariners all the air they need to breathe while under water; and how they "fight" the boat while they hunt other submarines.
