This article attempts to situate recent developments in the land armaments industry in France in the international economic context and highlight the main consequences. The progress made by the British group BAE Systems clearly changes the landscape, previously dominated by US companies in Europe, with the emergence of a duopoly at the top, General Dynamics and BAE Systems, whose partly misleading appearance is shown. But these developments above all lead to a questioning of a certain idea of land armaments in Europe that should be taken into account, and an effort is needed to improve economic performance in this sector in France.
