Construction practice separated the types as clearly as size and weapons. Flower-class corvettes used commercial standards so a broad range of yards could build them quickly. Frigates occupied an intermediate position, gaining more naval features without demanding the full effort of a sloop. Sloops were naval-standard warships with stronger subdivision and machinery, making them more capable but slower and harder to mass-produce.

Corvettes, frigates, and sloops used different construction standards
The escort labels also reflected a ladder from commercial construction through an intermediate frigate standard to naval-standard sloops.
