France and Germany have officially stopped working together to develop a new sixth-generation fighter aircraft. This decision marks the end of one of Europe's most important defense cooperation projects.

法國與德國已正式停止合作研發新一代第六代戰鬥機。此決定標誌著歐洲最重要的國防合作計畫之一正式結束。

The Future Combat Air System (FCAS) began in 2017 and later included Spain. The goal was to replace the Rafale and Eurofighter fleets by 2040 with a system combining a crewed jet, drones, and a secure data cloud. However, the project failed because Dassault Aviation and Airbus could not agree on how to manage the work. Dassault insisted on leading the development to protect its intellectual property, whereas Airbus argued for a more equal partnership and the sharing of technology.

未來空戰系統（FCAS）始於 2017 年，隨後西班牙也加入其中。其目標是在 2040 年前，以一套結合有人機、無人機與安全數據雲的系統，取代 Rafale 與 Eurofighter 戰機機隊。然而，該計畫失敗了，因為達梭航空（Dassault Aviation）與空中巴士（Airbus）無法就工作管理方式達成共識。達梭堅持領導研發以保護其知識產權，而空中巴士則主張更平等的夥伴關係及技術共享。

In addition to industrial disagreements, the two countries had different strategic needs. France required the aircraft to be compatible with aircraft carriers and carry nuclear weapons, but German officials, including Chancellor Friedrich Merz, felt these features were unnecessary. Despite several high-level meetings between President Emmanuel Macron and Chancellor Merz, the two sides could not agree on the final specifications of the plane.

除了工業分歧，兩國的戰略需求也不同。法國要求飛機必須與航空母艦兼容並能搭載核武器，但包括總理 Friedrich Merz 在內的德國官員認為這些功能並不必要。儘管總統 Emmanuel Macron 與總理 Merz 進行了多次高層會議，雙方仍無法就飛機的最終規格達成協議。

This failure happens at a difficult time, as Russia continues its aggression in Ukraine and there is uncertainty regarding US security support under President Donald Trump. The US government has repeatedly urged European countries to spend more on defense and become more independent. Consequently, the collapse of the FCAS fighter project is seen as a major setback for the European Union's goal of creating a coordinated security system.

這次失敗發生在一個艱難的時刻，因為俄羅斯持續在烏克蘭採取侵略行動，且在總統川普領導下，美國的安全支持存在不確定性。美國政府多次敦促歐洲國家增加國防開支並提高獨立性。因此，FCAS 戰鬥機計畫的崩潰，被視為歐盟建立協調安全系統目標的一個重大挫折。

Although the project to build the fighter jet has ended, officials stated that the 'nervous system' of drones and data networking will continue under the FCAS name.

雖然研發戰鬥機的計畫已結束，但官員表示，無人機與數據網路的「神經系統」仍將在 FCAS 的名義下繼續發展。
