How does submarine dive and surface

Some submarines use two hulls—one inside of another—instead of ballast tanks. This design allows it to flood the outer hull with water, which causes the vessel to sink, while the crew work and live in the inner one. An example of a double hull design is the Russian Alfa Class submarine considered by many to be the hot rod sub of the Cold War for its incredible speed. Designed during the s, the Alfa Class submarine remains the fastest of its kind till this day, according to Foxtrot Alpha.
