A torpedo boat is a small, fast naval vessel designed primarily for launching torpedoes against larger ships. These boats are typically equipped with powerful engines and are built for speed and agility, allowing them to evade enemy fire while closing in on targets. They played a significant role in naval warfare, especially during the late 19th and early 20th centuries. Torpedo boats were often used in conjunction with larger ships, such as battleships and cruisers, to create a layered defense. Their effectiveness led to the development of more advanced vessels, including destroyers and fast attack craft, which continue to serve in modern navies around the world.
