Constructions Mécaniques de Normandie

What Constructions Mécaniques de Normandie does

Constructions Mécaniques de Normandie (CMN) is a French naval shipbuilder founded in 1946 in Cherbourg-en-Cotentin and operating today as part of the CMN NAVAL group, which also controls shipyards in Germany and the United Kingdom. The company designs, constructs, and supports a full range of military vessels — from 15-meter high-speed interceptors (DV16, HSI25, HSI32 MK III) through fast attack craft (FS46/56/65 Combattante-class) and offshore patrol vessels (CL55 MK II, CL65, CL75 MK II, Ocean Eagle 43 trimaran) to 90+ meter corvettes (BR71 MK II, SEAGUARD 96), plus landing craft and assault boats. CMN has delivered over 450 vessels to 42 navies worldwide and currently supports 35 of them with spare parts, Integrated Logistics Support (ILS), crew training, and Technology Transfer programs.

CMN monetizes through one-time vessel construction contracts with defense ministries and navies (enterprise field sales direct to military procurement offices), supplemented by recurring post-delivery revenue from ILS, In-Service Support, spare parts, training, and licensing/royalties from Technology Transfer arrangements such as the BR71 MKII build with Abu Dhabi Ship Building. Revenue streams also include a tidal energy business via the HydroQuest subsidiary (manufacturer of HQ 2.8 turbines for the FloWatt project at Raz Blanchard) and an ACE joint venture serving the nuclear industry with metalwork and piping. The company is privately held, was bought out by the Safa family in 1992, and is led by President and CEO Serge Quaranta.

Technically, CMN integrates structural design, propulsion, piping, HVAC, electrical, and combat systems (including EMI/EMC and radar cross-section management), and has pioneered the 'dronisation' of its interceptor line — demonstrated in 2022 by remote piloting the UHSI32 over ~5,000 km from Cherbourg to Riyadh, and in September 2025 by autonomous navigation, obstacle avoidance, and interception with the USHI32 MkII in partnership with Anschütz and MTG Marinetechnik. The HSI32 was named Best High-Speed Interceptor in Europe 2025 and the UHSI32 was Interceptor of the Year 2022.
