Military activity was most intense during the mid-1970s, at the time of the crisis of decolonisation of Western Sahara and its occupation by Morocco. Military crises in Western Africa, like the 2013 Mali intervention by France, made Gando Air Base the main air platform for operations in Western Africa area by NATO. In 2006 Spain proposed Gando Air Base as headquarters for the newly created United States Africa Command (AFRICOM), but the AFRICOM HQ was ultimately based in Stuttgart, Germany.
