Submarines

Submarines are underwater crafts that revolutionized sea exploring. Submarines enabled people to explore the deepest parts of the ocean below the waters surface. Nowadays there are really high tech submarines called Submersibles. They are connected to ships and do not have to have people in them.

Most Submarines contain very high tech machinery for example radars which can detect in coming objects from a distance. Submarines also have a machine called a periscope which comes out of the top of the submarine and can come out of the water to see what is above the water.

Submarines where world famous in the second world war. They were used to silently sneak attack aircraft carriers.
