. The defence of the French national airspace has always been based on 2 main aspects: * the peacetime security of the French airspace. This assignment is executed according to the fixed conditions of the French prime minister collaborating with the ministers of transport, foreign affairs, industrial, postal and communication services, interior management and colonial management. * the national military air defence consisting of all defensive and counteroffensive measures against eventual aggressors.

These units may be deployed at any time to support the fixed operational systems.
