The biggest nuclear submarine in the world that is open to visitors

On the 29th March 1967, General de Gaulle presided over the launch of the 1st French nuclear-powered submarine, and now at La Cité de la Mer you can see it for yourselves.

Come and take a tour with an audioguide of the only nuclear submarine open to visitors in the world: visit the boiler room with propulsion systems, the torpedo storage room the “PNCO” (central navigation and manoeuvring workstation). You’ll be impressed by the sixteen missile launching tubes.

Some figures: 

  • 14,000,000 hours of labour,
  • 6,000 construction plans,
  • 7,000 tonnes of steel,
  • 6 km of welding across the outer shell,
  • 24 sections, each weighing 200 tonnes.

On this tour with audioguide (35 minutes), you’ll discover the cutting-edge technology used on a submarine and you’ll learn all about what life was like for the crew on board.

Children aged between 5 and 12 will have their own audioguide, designed especially for them, free-of-charge, to learn about this giant of the seas!
