The submarine had been envisioned by ancients as a weapon to be used against surface ships. Hundreds of years went by before technology allow construction of one. The "real" boats were around in a limited way in WWI, but by WWII, they kicked butt. Today, we have superb military submarines. The submarine was also seen as a research vessel and a recreational vehicle before they advent of the "real" submarine.
There are now 'Attack' submarines who's main purpose is to sink enemy submarines and ships and also Missile submarines whose main purpose is to launch ballistic missiles at the enemy.

The normal operating depth of submarines varies depending on their design and purpose. Most military submarines can operate effectively at depths of around 300 to 600 meters (1,000 to 2,000 feet), while some advanced models can dive deeper. Research submarines, like the DSV Alvin, can reach depths of over 4,000 meters (about 13,000 feet). However, the exact operational depth is often classified for military submarines.
