U-Boats were German Submarines that caused havoc to the US Navy as well as merchant ships. They nearly cut off all trade between the US and Europe, as well as caused much damage to the US and Royal Navies. Their weapons were torpedoes fired just below the surface that if successfully hit their target could bring a ship down with ease.
