In a sign of the growing security nerves in Europe, France has embarked on a $1.7 billion (€1.5 billion) renovation of an air base in remote hills in the east of the country so it can handle nuclear-armed bombers.
The work will take a decade but from 2035 the Luxeuil-Saint Sauveur base will be twice the size it is now and it will house new generation hypersonic missiles carried by 50 of France's Rafale fighter jets.
