What is the difference between a normal ship and a submarine?
Normal ships are designed to move on the surface of the water. Submarines are designed to be able to submerge and travel under the water's surface, as well as on the surface. When normal ships go down, they stay down. Submarines are able to come back up after they go down. All American submarines are nuclear powered. With the exception of Aircraft carriers, surface ships are powered conventially.
Why does the submarine float and submerge in water?
Submarines must be able to float to load and offload crew and cargo and to have repairs and maintenance. They are designed to submerge either for underwater exploration or to pass undetected by ships at the surface and planes and satellites above.
Why do ships float while submarines sink?
Submarines are designed with enough ballast and control systems to allow them to submerge and surface as needed.Surface ships are designed only with enough ballast and control systems to keep them on the surface. While they can sink just as well as submarines can, their ability to re-surface without a salvage operation is non-existent.
