The torpedo is one of the most crucial weapons for any submarine, acting like an underwater missile that can even carry a nuclear warhead. It typically gets its energy from an internal battery, which powers a propeller at the back, allowing it to move forward. However, not all torpedoes rely on battery power—some use compressed fuel, and others even use rocket propulsion. Communication with the torpedo happens through an optical fiber cable, similar to those used for the internet. This fiber connection is essential because using radio waves would make the torpedo detectable on enemy radar, while incoming sound waves guide it to its target. Notably, anti-submarine torpedoes can also be launched from ships, expanding their defensive capabilities.
