A destroyer squadron is a naval squadron or flotilla usually consisting of destroyers rather than other types of vessel. In some navies other vessels, such as frigates, may be included. In English the word "squadron" tends to be used for larger and "flotilla" for smaller vessels; both may be used for destroyer units. Similar formations are used in non-English-speaking countries, e.g., the "escadrille"—which would translate directly as "squadron"—in France.
