Which nation or shipbuilding company produced the most destroyers?
Short answerYarrow and Vickers were major builders; nationally, the United States probably leads over the longer span, while Britain may have held a slight interwar edge.
NotesThe audience asks for both a national and a company comparison, and the answer depends on the period being counted. Yarrow and Vickers were major destroyer builders, particularly for Royal Navy demand. By nation, the United States probably leads over the longer span because of its post-World War II fleet, while Britain may have held a slight interwar edge and also built heavily during the wars. These remain informed estimates rather than a precise ranking.
