Japan has expressed concerns over potential delays in the Global Combat Air Programme (GCAP) due to Germany’s possible involvement. The joint fighter jet project, which includes Britain and Italy alongside Japan, aims to develop a next-generation combat aircraft by 2035. German Chancellor Friedrich Merz showed interest in collaborating during talks with Japanese Prime Minister Sanae Takaichi in Tokyo on October 28, indicating that Germany and Japan would explore the feasibility of cooperation in fighter aircraft development.
The GCAP is a significant defense initiative designed to produce an advanced fighter jet. However, Japan worries that Germany’s participation could necessitate changes to the current division of responsibilities among the partner countries, potentially disrupting the project timeline. A source from the Japanese Defence Ministry noted that Germany’s involvement would likely require renegotiating the existing work-sharing agreements with Britain and Italy.
Despite these concerns, Britain reportedly sees potential benefits in Germany joining the program, as it could help share development costs and lower the aircraft’s unit price by increasing potential orders. In response to the situation, Japan plans to consult with Britain and Italy to explore the extent of Germany’s possible cooperation.
One proposed solution is for Germany to join as an observer, which would allow it to participate in information exchange and consider purchasing the aircraft, without directly impacting the program’s development schedule. This approach might mitigate Japan’s concerns about potential delays while still involving Germany in the project.
