A frigate is a type of warship that is generally smaller than a destroyer but larger than a corvette. It is designed for various roles, including escorting larger vessels, anti-submarine warfare, and patrolling coastal areas. Frigates are equipped with advanced radar and weapon systems, making them versatile in modern naval operations. These ships often carry a combination of missiles, torpedoes, and anti-aircraft systems. Frigates are commonly used by many navies around the world, including the United States Navy and the Royal Navy, to protect maritime interests and maintain security in international waters.
