The Ciclone class were a group of torpedo boats or destroyer escorts built for the Italian Navy which fought in the Second World War. They were modified, slightly heavier, versions of the previous Orsa class, with improved stability and heavier anti-submarine armament. These ships were built as part of the Italian war mobilization programme and completed in 1942–43.
