Japan has expressed concerns that Germany’s potential involvement in the Global Combat Air Programme (GCAP) could delay the development of its next-generation fighter jet, a collaborative project with Britain and Italy. The apprehension arises following German Chancellor Friedrich Merz’s discussions with Japanese Prime Minister Sanae Takaichi in Tokyo on October 28, where Merz suggested exploring cooperation possibilities in fighter aircraft development.
The GCAP is a significant defense initiative aimed at developing an advanced fighter jet by 2035. Japan worries that Germany’s entry into the project might necessitate changes to the existing division of responsibilities, potentially disrupting the timeline agreed upon by the current partners. A source from the Japanese Defence Ministry highlighted that Germany’s participation would likely require renegotiating the work-sharing arrangements previously established by Japan, Britain, and Italy.
Despite Japan’s concerns, Britain reportedly views German involvement as a means to share development costs and lower the aircraft’s unit price by expanding potential orders. The possibility of Germany joining the program has prompted Japan to seek consultations with Britain and Italy to evaluate the extent of Germany’s potential cooperation.
One proposed solution is for Germany to join the project as an observer. This arrangement would enable Germany to exchange information and consider purchasing the aircraft without directly impacting the program’s development schedule. As discussions continue, Japan remains focused on ensuring the project stays on track for its planned 2035 deployment.
