France’s next-generation aircraft carrier will be nuclear-powered and replace the national fleet’s flagship warship, the Charles de Gaulle, in 2038, President Emmanuel Macron said on Tuesday.

The 11th carrier-vessel in the French Navy’s will be equipped with the new electromagnetic aircraft launch system developed by U.S. company General Atomics, French officials said.

The carrier will be 300 metres (984 ft) long and have a deadweight of 75,000 tons. It will be able to carry up to 30 Rafale fighter jets or the successor of the Dassault warplane currently being developed by France, Germany and Spain.

France’s military had initially lent towards a ship with conventional propulsion, but together with Macron later opted for a nuclear-powered vessel, despite heavier construction costs, for technical and strategic reasons.

-Out strategic future, our status as a great power, lies with the nuclear industry- Macron said during a visit to a nuclear sector components maker.

France is continental Europe’s only nuclear power. Britain is a nuclear power too, though its relationship with the European Union -- from trade to security -- once it leaves the EU’s orbit on Jan. 1 remains uncertain.

The French state will invest one billion euros during the first development phase that will end in 2025, the Ministry of Armed Forces said. Ministry officials declined to comment on media reports that the vessel could cost more than 5 billion euros ($6.05 billion).

Three other Western aircraft carriers have been built since the Charles de Gaulle was first deployed. The U.S. Navy’s Gerald R. Ford and America, and the British Royal Navy’s Queen Elizabeth, which cost about 3.1 billion pounds ($4.03 billion).
