We use Value Sensitive Design for the development of an ethical framework for autonomous systems in Defence in the Australian context. Two novel empirical data gathering methods are deployed for mining stakeholder's values, namely Group Decision Room (GDR) and Participatory Value Evaluation (PVE). GDR findings reveal a general concern for environmental values, geo-political and economic stability. A PVE based on these and other values is designed around an autonomous mine counter underwater vessel and an autonomous drone that drops bombs.
