The Horizon class (French: Classe Horizon; Italian: Classe Orizzonte) is a class of air-defence destroyers in service with the French and Italian navies. They are designated as destroyers by the Italians and are referred to as "frigates" by the French but nonetheless also use the NATO classification "D" intended for destroyers. The programme started as the Common New Generation Frigate (CNGF), a three-nation collaboration between France, the United Kingdom, and Italy to develop a new generation of air-defence warships. Differing national requirements, workshare disagreements and delays led to the UK withdrawing from the project in 1999 to develop the Type 45 destroyer. The FREMM multipurpose frigate were built using the same company structure as the Horizon project.
