In April 1958, following a meeting of NATO defence ministers, an agreement was formed that the G.91 would be the first NATO lightweight strike fighter, and that it was to be followed in 1961 by "a developed version" of the Breguet Taon. In May 1958, a production meeting was scheduled to discuss the production of the aircraft with financial support from the United States; the Americans would provide some of the finance for the French, German and Italian aircraft, in addition to paying for the Turkish aircraft. The defence ministers reached an agreement to order 50 aircraft for each country.
