Destroyers, or known as originally Torpedo Boat Destroyers, are small, fast and unarmored ships that were very commonly used during World War II. Destroyers usually had 4-5 inch guns, had 3-10 torpedo tubes, and also had Anti- Submarine artillery on board. These ships were meant to escort bigger, more armored ships in a fleet across the oceans. They were also meant to keep other destroyers at a distance from bigger ships in the fleet. Their maximum speed was around 34 knots or around 39 miles per hour. Destroyers are the basis of any modern naval fleet today, with many of them now carrying cruise missiles instead of solely relying on torpedoes and gunfire to take down other ships.
