A torpedo is a self-propelled weapon designed to travel underwater and explode upon impact with a target, typically a ship or submarine. It is launched from various platforms, including submarines, ships, and aircraft. Torpedoes are equipped with guidance systems that help them navigate toward their target, making them effective in naval warfare. The design of a torpedo includes a cylindrical body filled with explosives and fins for stability and steering. Modern torpedoes can be guided by sonar or other technologies, allowing them to adjust their course during flight. They play a crucial role in naval strategy and defense, particularly in engagements involving naval forces and submarines.
