Why did the US Navy have no corvettes in the Second World War?
Short answerIt did: Flower-derived ships served as Temptress- and Action-class gunboats, obtained from British and Canadian production.
NotesThe US Navy operated Flower-derived ships under gunboat classifications. British-built examples were the Temptress class, while Canadian-built ships formed the Action class. Canadian yards named in the account include Collingwood, Kingston, and Midland. The ships answered an American shortage of escorts. Their transfer also illustrates assistance moving toward the United States within the wartime alliance. HMS Victorious's temporary service with the US carrier force provides a second example of that direction of support.
