Which ship classes from the world wars and Korean War are most often overlooked?
Short answerFlower-class corvettes and especially the earlier Flower-class sloops are singled out. A later contribution adds U.S. Navy repair ships such as Vulcan.
NotesThe First World War Flower-class sloops are easy to overlook, especially because the better-known Second World War ships were corvettes. Confusing the two can erase an entire earlier group from discussions of small warships. The Royal Navy repeatedly returned to flower names when it needed to expand its small-vessel force quickly. The answer also notes that one of the First World War sloops survived through both world wars, without identifying it.
