What is the difference between a normal ship and a submarine?
December 25, 2009 4:54AM
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.
