Following the publication of NATO’s “Overarching Space Policy” and the declaration of Space as an Operational Domain in 2019, this branch was established in 2020. NATO’s dependence on Space systems implies the need to ensure that resources and capabilities are available during all operational phases. The lack of Space capabilities and products could hamper the success of NATO operations.

Our Space branch supports coordinating the Global Programming Process for the best available education and training regarding needs defined by the Bi-SC directives, led an Annual Discipline Conference for Space and prepared the implementation of the Space Domain within NATO. More specifically, we not only provide support in functional areas of space (PNT, ISR, METOC, SSA, SATCOM and MD) but also offer multinational expertise to key decision-makers for effective solutions on Space Power challenges, in order to safeguard the Alliance.
