How many 1918-1919 destroyer leaders was the US Navy likely planning?
Short answerThe answer estimates the requirement from the very large four-stack destroyer program, roughly one leader for each flotilla-sized group.
NotesThe answer approaches the question through force structure rather than a single surviving plan. With destroyers being ordered by the dozen, leader requirements would follow the number of flotillas the four-stack program could create. Procurement totals can therefore imply command-ship needs even when the exact staff paper is unavailable.
