Project history

"Flower" with considerably increased fuel stowage. They were built in Britain and Canada and differed only by boilers: British-built ships had traditional fire-tube but Canadian-built ships had water-tube ones. All 10 ships built in Britain were transferred to Commonwealth navies. 27 corvettes were built for RCN (under 1942-1943 and 1943-1944 Programmes, the order for 6 ships had cancelled) and, besides, 15 corvettes were built under British order for transfer to the USA by "reverse" lend-lease. By the moment of their completion USN did not feel any more lack in the escorts and commissioned 8 corvettes only (classified as gunboats), remaining ships were returned to RN (besides in lend-lease frameworks, this time direct).

Modernizations

None.
