Submarine warfare involves the use of submarines to conduct military operations beneath the surface of the water. Submarines can be used for various purposes, including reconnaissance, launching attacks on enemy ships, and gathering intelligence. They are equipped with torpedoes and missiles, making them effective in naval combat. The strategic advantage of submarines lies in their stealth and ability to remain undetected. This allows them to surprise enemy vessels and carry out missions without being easily targeted. Throughout history, submarine warfare has played a significant role in conflicts, notably during World War I and World War II.
