Destroyer escorts and frigates used different wartime standards

What was the difference between a destroyer escort and a frigate during the Second World War?

Destroyer escorts retained fuller naval construction standards, while frigates were simplified two-screw escorts designed for fast production in less-specialized yards.

The panel distinguishes a destroyer escort built to fuller naval standards from a frigate deliberately adapted for rapid construction outside specialist warship yards. Corvettes sat closer to commercial practice and commonly used one screw, while frigates used two screws and semi-naval subdivision and survivability standards. This made frigates accessible to yards without deep warship-building experience and reduced demands on scarce specialist materials. Lloyd's construction rules provide a useful framework for understanding these categories even as definitions evolved during the war.
