A frigate or cruiser is a type of VESSEL used by navies around the world. Frigates and cruisers are both large warships, but frigates are generally smaller and less heavily armed than cruisers. Frigates are typically used for patrolling, convoy escort, and anti-submarine warfare, while cruisers are used for long-range operations and power projection. Both types of vessels are equipped with a variety of weapons, including missiles, torpedoes, and guns.
