Submarine Coloring Page

Modern submarines can dive between 600 and 1,000 feet, though military submarines reach much deeper. The deepest diving submarine ever was the Trieste, which descended nearly 36,000 feet into the Mariana Trench in 1960. This incredible depth is possible because submarines have reinforced hulls made of special metals that resist enormous water pressure.

Submarines use special compartments called ballast tanks that fill with water to make them heavier and sink, or fill with air to make them lighter and rise. By carefully controlling how much water enters these tanks, submarine crews can stay at exactly the right depth. This ingenious system lets them hover silently beneath the waves.

Submarines have systems that either carry oxygen tanks, generate oxygen through chemical reactions, or use air-independent propulsion that doesn't require oxygen from outside. Modern nuclear submarines can stay underwater for months because they produce fresh water and oxygen through special machines. Older submarines had to surface regularly to get fresh air.
