The Horizon class is a class of air-defence destroyers in service with the French Navy and the Italian Navy. It is easily distinguishable from the Royal Navy Type 45 destroyers by the port and starboard guns located below the bridge. The programme started as the Common New Generation Frigate (CNGF), a multi-national collaboration to produce a new generation of air-defence destroyers. In Italy the class is known as the Orizzonte class, which translates to "horizon" in French and English. The UK then joined France and Italy in the Horizon-class frigate programme however, differing national requirements, workshare arguments and delays led to the UK withdrawing on 26 April 1999 and starting its own national project, the Type 45 destroyer. The FREMM multipurpose frigate are currently under construction using the same company structure as the Horizon project. After withdrawing from the Horizon program the UK then went on to build Daring D32 / Dauntless D33 / Diamond D34 / Dragon D35 / Defender D36 / Duncan D37.
