Counting options, this brings MSC's orderbook to a whopping 11 ships: eight in France and three in Italy.
Today's newbuilds will be of a 'World Class' prototype design, which MSC Cruises executive chairman Pierfrancesco Vago said will be 'quite unlike anything currently existing in the cruise industry.'
Vago promised cutting-edge design, maximized open-air space, features for adults, families and children and 'a ship for all seasons and for all regions.'
The deal, officially announced this afternoon by French President François Hollande at his Elysée Palace residence in the presence of Gianluigi Aponte, founder and executive chairman of MSC Group, and Laurent Castaing, general manager of STX France, was described as 'the order of the century' by Elysée spokesman Stephane Le Foll, on French television this morning.
The French government holds a 33.4% stake in the Saint-Nazaire yard.
The deliveries are scheduled in 2022, 2024, 2025 and 2026.
MSC already has four ships under construction at Saint-Nazaire: two in the 4,500-berth Meraviglia class to be delivered in 2017 and 2019, as well as two larger, 4,888-berth Meraviglia-Plus ships for delivery October 2019 and September 2020.
Speaking in French, Aponte cited the quality work of the French yard, the calm labor situation which ensures on-time deliveries and the vital contribution of Coface, the export credit agency. He said today's order would represent 36m hours of work and, by 2026, MSC will have invested €7bn in France and created 70m hours of work, equivalent to more than 3,000 full-time jobs over 12 years.
At Fincantieri in Italy, the company has two firmly contracted 154,000gt MSC Seaside vessels plus an option.
MSC has built 12 ships at STX since 2002. The next delivery will be 167,000gt MSC Meraviglia in June 2017. A second Meraviglia-class ship will be handed over in June 2019.
'In our memories,' President Hollande said, 'we have names such as Normandie, France, Queen Mary 2. MSC Meraviglia will be their follower.'
