| Notes on class | After U-boats demonstrated mid-Atlantic attack capability from French bases, construction of Flower class corvettes designed for coastal escort was discontinued in favour of River class frigates better suited for ocean escort work. Shipyards too small to build 300 foot frigates began producing an improved 250 foot corvette called the Castle class. |
