Frigates generally serve as escorts for larger capital ships. Ample speed and acceleration, combined with enlarged cargo and weapons space, make this class of ships ideal for long-range patrols and scouting missions. Frigate-class carriers are cramped for space, but nonetheless do allow for rapid deployment of a fighter wing.
