The head of France's Dassault Aviation said on Wednesday, April 1 he was giving his company "two to three weeks" to see if the multibillion-euro warplane program with Germany could work as the government tries to salvage the project.

He spoke after French President Emmanuel Macron and German Chancellor Friedrich Merz voiced determination to rescue the program. Merz said last week that two mediators had been tasked with making a proposal by the end of April.
