The Submarines

Submarines are water transport vehicles. People use them to travel under water. 

Scientists go in submarines to study about water animals we don't even know about. Militaries use submarines to patrol oceans and to attack enemy ships during war. Militaries submarines carry missiles and torpedoes. A submarine has a big tank called a ballast tank. The submarine is light for it's size so the ballast tank gets filled up with water and the submarine sinks. When the submarine is ready to surface the the ballast tanks release the water and fill with air so the submarine starts to float.
