Flotilla

A flotilla (from Spanish, meaning a small flota (fleet) of ships, and this from French flotte), or naval flotilla, is a formation of small warships that may be part of a larger fleet. A flotilla is usually composed of a homogeneous group of the same class of warship, such as frigates, destroyers, torpedo boats, submarines, gunboats, or minesweepers. Groups of larger warships are usually called squadrons, but similar units of non-capital ships may be called squadrons in some places and times, and flotillas in others.
