Nuclear submarines are at the pinnacle of modern marine warfare. The design & engineering of these nuclear submarine monuments have been closely guarded secrets from their beginning. Here are 10 design features of nuclear submarines that have been declassified over time.

Electrolysis air system - The first hurdle to underwater operation was to provide a breathable atmosphere. That’s over 12 cubic metres of air per crewmember per day. Depth control - The captains of the first submarines controlled their depth by pumping water in and out of ballast water tanks. Electric torpedoes - Early torpedos used compressed air to drive them thru the water, but the line of air bubbles they produced easily revealed their presence to vessels on the surface, making them easy to avoid. Remote-controlled and programmable torpedos - One limitation of electric torpedoes is controlling them: essentially, they continue in the direction they are launched. Nuclear reactor - All of the systems on board the submarine draw power. Steam-driven vertical launch missiles - During the cold war, the Russians got the upper hand with the ability to fire nuclear weapons from submarines. Passive and active sonar - Hiding underwater, the submarine is hidden from view, but not entirely undetectable. Sound is their enemy where light doesn’t penetrate. Silent running thru isolation and hydrodynamics - Since sound travels underwater for great distances, the hum from a motor or the tick of a clock could give away the location of a submarine. Hull pressure chamber and Hull tiles - The design of the hull has evolved from an oak shell held together with barrel hoops to a pressure vessel that can dive to more than 240 metres where the pressure is equivalent to 25 atmospheres. Multi-Mission Platform Seawolf-class Submarine - The Cold War drove the United States to design their most silent fast attack submarine, the Seawolf.
