Rethinking UK Autonomy in Space Nationally Separable Capabilities

Space capabilities are deeply embedded in both allied and commercial architectures. This may be rational and effective, but it constrains national freedom of action when events demand that such freedom be maintained. Scott Mackie discusses the concept of national separability: systems designed so that, while integrated in peacetime, they can be employed under national political authority when allied or commercial cooperation is constrained. Distinguishing separability from sovereignty, this article argues that separability is a property of use rather than ownership and offers middle powers a realistic way of managing interdependence without retreating from it.
