New military inventions shaped the outcome of war in many ways. One way would be how warships have changed fighting in the sea. A submarine is a good example of this. There are different submarines for different missions and come in different shapes and sizes. They are propelled by electric motors and batteries. This helps because they have less people to rely on and go much faster in the water. They use sonar and radar to find enemy submarines and any other target they need to find. Submarines travel deep in the water and many types of submarines carry missiles, torpedoes, and other weapons. They don’t have to be on land or on the surface of the sea to battle. They are able to shoot missiles and torpedoes underwater from far distances.
