Joint German‑French weapons programs often stall because, despite political alignment, the two countries have different military requirements, industrial interests, and strategic cultures. This leads to prolonged timelines, rising costs and sometimes outright cancellation.
Key issues include operational mismatches—France focuses on lighter, mobile systems for overseas missions in Africa and the Middle East, while Germany prioritises heavier equipment for European defence against Russia. In the MGCS future tank project, France pushes for a new combat system with drones and advanced weapons, whereas Germany prefers a direct Leopard 2 replacement.
Industrial competition further complicates matters, as seen in the sixth‑generation fighter FCAS where Dassault and Airbus dispute design control and technology ownership, and in MGCS where German and French firms clash over workshare. Export policy differences also cause friction: France wants unrestricted sales of joint products, while Germany’s stricter rules can block sales, creating mistrust.
Bureaucratic hurdles, slow decision‑making and differing timelines—France tolerates long‑term development, whereas post‑Ukraine war Germany seeks rapid solutions—add to the challenges.
