How corvettes, sloops, and destroyer escorts differed

What is the difference between a corvette, a sloop, and a destroyer escort?

Corvettes emphasize merchant construction, sloops are naval-standard low-speed escorts, and destroyer escorts are intended to be larger and faster, though wartime designs overlapped.

Corvettes are described as merchant-yard hulls and construction standards adapted with naval weapons and only the necessary military changes. Sloops use naval standards but accept lower speed for escort and anti-submarine work, while destroyer escorts are meant to be larger, more thoroughly militarized, and faster; wartime British designs blur those boundaries because Hunts and Black Swans grew from related escort traditions.
