Submarine

the boat that doesn't float

Its creation

The submarine was first planned to be in the U.S. Navy in 1875, but the inventor, John Holland, was rejected of those plans. A group of Irish men that hoped to destroy England's Navy and funded Holland to build two submarines. The first one failed, while the second one, launched in 1881 was successful. The success has based most of the basic features of submarines even today. The final launch of a submarine was put in the Navy successfully in 1898. The inventor, John Holland, was born in 1841 as an Irish American. He died in obscurity on August 12, 1914

How it works

overveiw

Submarines are cigar shaped, to reduce drag for aerodynamics. This cigar shape can be called a tear drop hull. The outer hull is covered in a sound absorbing rubber, to make it hard to detect. They contain air for many people to be in the hull. Submarines use GPS to maneuver under water. They can control their buoyancy, they have large tanks that fill up with air if they want to go up or fill up with water to sink to their depth. The hull has air containers that will have the needed air for temperature, and air for living.

Benefits and evolution

The submarine has advanced naval warfare in all of the modern countries that use it. The submarine started off as a boat that can go under water for short periods of time. it has evolved into one of the worlds most stealthy, deadly war machines.
