The first submarines used in wars were not very mobile as no real engines had bee made for them, -So they had very short range and primarily used to plant bombs under or on the hull of enemy ships in harbour .
-By the time of WW1, submarines had electric motors for subsea propulsion and diesels for surface running (the diesels also recharged the huge battery banks) In this much more efficient form, submarines were used to attack enemy supply ships and thus starve the enemy of much needed supplies.
In WW2 and later, attack submarines were developed and these could often sink enemy warships.
In the latest type of nuclear 'boomers' , submarines can carry ICBM's or cruise missiles and could lurk anywhere in the world's oceans.
Submarines fought in both WW1 and WW2.
Submarines have been used in most wars involving naval combat since WWI

During WW2, all the major countries involved used submarines.
They were used by submarines to navigate when not in open waters, They were also used by submarines and anti-submarine ships to locate enemy submarines.
Shallow diving submarines are used for reef watching in many parts of the world.
Nuclear energy is used to power most modern submarines
