How wartime sloops became modern frigates

Do modern frigates descend from Second World War escorts rather than sailing frigates?

The wartime escort lineage matters, but it revived an older small-warship name and developed closely through sloops and destroyer escorts.

There is no clean break between the sailing frigate and the modern escort label. During the Second World War, a somewhat larger escort built to semi-civilian standards was called a frigate and remained closely related to the sloop. Postwar classification then gathered destroyer escorts and sloops under the frigate name. The modern category is therefore a revived label shaped by escort evolution rather than a physically unchanged descendant of the sailing frigate.
