Why national industry makes multinational combat-air programs difficult

What are the main political and industrial obstacles facing GCAP and the separate German-French-Spanish combat-air program?

The programs face hard industrial and political tradeoffs because partners want different capabilities, technology rights, export policies, and protection for their national defense industries.

The prospects for a finished Franco-German-Spanish aircraft remain uncertain in this discussion. France already has much of the desired technology and openly requires a carrier version. Clarke sides with France in the immediate dispute, while recognizing Germany's case for industrial access in return for its funding. The French concern is that technology transfer could allow a partner to displace domestic industry. Export controls create another risk if one partner can block sales on which the others depend. Those experiences also shape resistance to expanding the British-Italian-Japanese partnership. National governments remain responsible for domestic strategic industries, so a consortium's preferred compromise need not suit every participant.
