Constructions Mécaniques de Normandie

Constructions Mécaniques de Normandie, commonly known as CMN, is a French shipbuilding company based in Cherbourg, Normandy. Founded in 1946 by aircraft constructor Félix Amiot, the yard developed from a small postwar vessel builder into an international producer of military and specialized ships. Its early output included wooden fishing vessels, but the company soon broadened its activities to minesweepers, coast-guard vessels, patrol boats, barges, fishing boats, and fast attack craft. The company’s historical identity is closely linked to the development of lightweight, low-signature naval platforms and to export-oriented construction programs. CMN became particularly notable during the 1960s for its use of a patented glued-laminated wood construction technique. The method was applied to minesweepers for the French and German navies and was intended to provide useful naval characteristics, including non-magnetic construction, sound absorption, and reduced acoustic reflection. The Circé-class minehunters became one of the best-known examples of this period; the first vessel was launched in December 1970, followed by four more between 1971 and 1972. The yard also expanded into fast attack craft from 1967. Its work on the La Combattante II design established a durable product family for missile and patrol warfare. CMN constructed nine boats for Israel after a German supply arrangement involving twelve vessels was curtailed under political pressure. The Israeli boats were designated as the Sa'ar 1 class, while related La Combattante II vessels were later supplied to other customers. During the 1970s, the West German Federal Navy ordered twenty La Combattante II fast attack craft. The Tiger class represented a further development of the design. In the 2000s, CMN developed the Combattante BR70 design, which became the basis for the Baynunah-class corvettes of the United Arab Emirates Navy. The lead ship was built at Cherbourg, while subsequent vessels were constructed in Abu Dhabi by Abu Dhabi Ship Building under a technology-transfer arrangement. This program illustrated CMN’s ability to combine design work, construction, and industrial cooperation with overseas shipyards. CMN’s activities extend beyond combatants. The company has built research vessels and provides naval and marine services, while its wider group is also involved in marine energy through HydroQuest. Its Cherbourg facilities include approximately 48,000 square metres of covered production space on a site of about 110,000 square metres. The yard has a slipway for vessels below 700 tonnes and a Syncrolift with lifting capacity of up to 3,000 tonnes. The company is reported to employ approximately 450 people across the specialist trades needed for ship construction. CMN is a subsidiary of the CMN Naval group, which also includes German Naval Yards in Germany, Isherwoods in the United Kingdom, and the subsidiaries HydroQuest, AMT, and ACE. The shipyard has delivered more than 450 vessels since its establishment. Its later export activity included the delivery of two warships to Saudi Arabia in 2019. In March 2026, according to the supplied reference material, CMN launched the first-of-class BR71 Mk II corvette, NRA Ekuikui II, for the Angolan Navy. The vessel was associated with an industrial arrangement involving EDGE Group’s naval division, Abu Dhabi Ship Building, with construction responsibilities distributed between Cherbourg and Abu Dhabi.

Constructions Mécaniques de Normandie was established in 1946 at Cherbourg by Félix Amiot, a French aircraft constructor. The company’s first vessel was a wooden trawler launched on 23 June 1948. From that starting point, CMN developed a broad construction portfolio that included fishing boats, barges, coast-guard vessels, patrol boats, minesweepers, and fast attack craft. During the 1960s, the company concentrated on naval applications of glued-laminated wood construction. CMN used a patented technique to build minesweepers for the French and German navies. The material and construction method offered properties suited to mine warfare, notably non-magnetic construction and reduced or controlled acoustic signatures. The Circé-class minehunters were an important program in this period. The first vessel was launched on 15 December 1970, and four additional vessels followed during 1971 and 1972. CMN entered the fast attack craft sector from 1967, using laminated, wood-cored hull construction. The international development of the La Combattante II family was influenced by the sinking of the Israeli destroyer INS Eilat by Egyptian missile boats in October 1967. Germany had originally agreed to supply Israel with twelve Jaguar-class boats, but political pressure led Germany to withdraw from the arrangement after three boats had been delivered. The remaining nine boats were instead constructed by CMN and became La Combattante II vessels designated as Sa'ar 1-class craft by Israel. The design subsequently gained further international use. In the 1970s, the West German Federal Navy ordered twenty La Combattante II fast attack craft. The Tiger class was a modified form of the French design. These programs helped establish CMN as an exporter of relatively small, fast naval combatants. In the 2000s, CMN developed the Combattante BR70 design. It served as the foundation for the Baynunah-class corvettes built for the United Arab Emirates Navy. CMN constructed the lead vessel at Cherbourg, while Abu Dhabi Ship Building built the remaining vessels in Abu Dhabi under a technology-transfer program. This represented a shift from simple vessel export toward cooperative production and local industrial participation. CMN later continued to serve military and specialized maritime customers. The company delivered two warships to Saudi Arabia in 2019. Reference material supplied for this dossier states that in March 2026 CMN launched NRA Ekuikui II, the first BR71 Mk II corvette, for the Angolan Navy. The design is described as an updated development of the Baynunah-class concept. The same material associates the program with EDGE Group’s naval business, Abu Dhabi Ship Building, and a split construction arrangement involving CMN and Abu Dhabi. Today, CMN operates from a substantial Cherbourg site and employs approximately 450 people in shipbuilding and related specialties. Its activities include military vessels, research vessels, yachts, and associated naval services. The company is part of CMN Naval, a broader group that includes German Naval Yards, Isherwoods, HydroQuest, AMT, and ACE. Since its foundation, the yard has delivered more than 450 vessels.
