European defence cooperation has hit another roadblock. After the collapse of the Franco-German FCAS fighter jet programme, the Main Ground Combat System (MGCS) joint tank project is now facing a similar fate. A key document from the latest Franco-German Defence and Security Council meeting contains no mention of the common tank, signalling a major strategic shift.
The MGCS programme, launched in 2017, was meant to replace the German Leopard 2 and French Leclerc tanks by 2035. In April 2024, the defence ministers of both countries signed a formal agreement, with German minister Boris Pistorius calling it a historic moment. Yet behind the scenes, national industrial rivalries and diverging strategic interests have been slowly derailing the project.
From historic agreement to stalemate
According to Polish daily Dziennik Gazeta Prawna, the final resolution of the 26th Franco-German Defence and Security Council meeting only states that both sides will “examine a system-based approach as an integral part of future multi-domain operations.” There is no commitment to a common tank platform. Observers note that the vague wording effectively freezes the MGCS programme indefinitely.
The failure is rooted in the competing priorities of France and Germany. Paris insists on retaining full sovereignty over key components while Berlin pushes for standardisation and shared production. The result has been years of deadlock, with no breakthrough in sight.
Parallel failure: the FCAS precedent
The MGCS crisis mirrors the earlier collapse of the Franco-German Future Combat Air System (FCAS) project. In June 2026, it was confirmed that Dassault and Airbus could not agree on the fighter jet’s development, despite over a decade of work. The FCAS programme, estimated at more than €100 billion, was meant to replace the Eurofighter and Rafale by 2040, integrating drones and a combat cloud network.
Both failures highlight a deeper structural problem in European defence collaboration. National champions struggle to compromise, and political will is often insufficient to overcome technical and commercial hurdles. For Poland, which is rapidly modernising its armed forces, the demise of MGCS may reinforce the logic of buying proven off-the-shelf systems from the US or South Korea.
As European powers bicker, the security landscape in Eastern Europe continues to harden. The question now is whether Berlin and Paris can salvage any of their ambitious armament plans or whether the era of joint European tank programmes is over.
