One functional classification treats modern general-purpose escorts as performing the peacetime work once associated with cruisers. They show the flag, conduct presence missions, and represent naval power abroad regardless of their formal type label. Frigates act as anti-submarine cruisers in this scheme, while destroyers act as anti-air-warfare cruisers. Ships officially called cruisers may differ chiefly through additional command systems, which shows why type labels do not always describe operational employment cleanly.
