The German government said last Friday that France, Germany and Spain had reached agreement on starting the next phase of development of the new fighter jet dubbed FCAS, Europe's largest defence project which has an estimated cost of more than 100 billion euros ($102.32 billion).
"There was a sort of pseudo-political announcement that was made. I think that the German approvals - which were hard to get - had come out and that in turn led to some leaks. But it is not yet done," Trappier told RTL Radio.
France's Dassault Aviation, Airbus and Indra - the latter two representing Germany and Spain, respectively - are involved in the scheme to start replacing French Rafale and German and Spanish Eurofighters from 2040.
