Modern labels often describe specialization: frigates lean toward anti-submarine work and destroyers toward air defence, while both still conduct independent deployments and presence missions. Because peace is more common than war, endurance, affordability, and diplomatic utility shape everyday fleet value.

A navy with few large hulls cannot reserve presence work for a separately named cruiser force, so its principal escorts must be able to cruise by default.
