The potential for autonomy (i.e. autonomous systems) is starting to become clear in the military context. However, most of the focus and research has been oriented towards the exploration of the technical aspects of autonomy and less on the cost related implications of autonomy for current and future military operations (e.g. SAS-097 Robotics Underpinning Future NATO Operations, SCI-296 Autonomy from a Systems Perspective, SCI-ET-012 Affordable Robotics for Military Operations). Moreover, in terms of costs, there is a general belief that autonomy will reduce costs1. Therefore, it is important to develop a better understanding of the cost related implications of the introduction and use of autonomy in the military environment.
