The National Security College, with the support of the Carnegie Corporation of New York, is leading a two-year research project on strategic stability in the Indo-Pacific region, with a focus on new technologies relating to undersea warfare and nuclear deterrence looking out over a 20-year timeframe. A distinctive contribution of the project will be its consideration of these levels of analysis – nuclear strategic, maritime operational, and technology – in an Indo-Pacific regional context. The project has conducted research workshops, a major international scenario exercise and multi-disciplinary technology assessment activities. We have also commissioned a range of leading international scholars and security practitioners to outline current knowledge and expert judgements in related fields to broaden knowledge about undersea nuclear deterrence and the impact of technological advances, changes in nuclear capabilities and multipolarity on the future of strategic stability.
