Which type of naval vessel is a multi-purpose ship that relies on speed and mobility for defense?

A destroyer is classified as a multi-purpose naval vessel designed primarily for speed, maneuverability, and flexibility in various operational roles. These ships are equipped to engage in anti-submarine, anti-air, and surface warfare, making them adaptable for different scenarios at sea. The destroyer’s emphasis on speed and mobility allows it to quickly respond to threats and protect larger vessels in a fleet.

In contrast, other types of ships like frigates and submarines have specialized functions and may not prioritize speed to the same extent. For instance, while frigates also serve multiple roles, they are generally smaller and optimized for escorting larger vessels, emphasizing anti-submarine warfare rather than high-speed engagements. Battleships, on the other hand, are heavily armed and armored, focusing on sustained firepower rather than speed. Thus, the destroyer stands out as the vessel best equipped for rapid response and diverse operational capabilities.
