    This report considers the problem of disruptive changes in the technologies for detection of SSBNs and how they intersect with the growing or continued reliance on submarines for retaliatory nuclear capability. In simple terms, this report answers the question: Will future science and technology make the oceans transparent? It takes a scientific perspective and considers the science and technology issues bearing on ocean sensing and the detection of submarines as anomalies in the water column. This report utilises a time horizon spanning to the 2050s, as the next generation of nuclear-armed submarines will be deployed through the 2030s and beyond. Its analysis identified broad areas of future science and technology – rather than specific ‘hot’ areas of the moment – that might have an impact on submarine detection as well as on counter-detection. This report makes two strong findings: Favourable geographies that the West took advantage of in the Atlantic during the Cold War, and more recently in the Pacific in its strategic rivalry with China, will not have the same salience in the 2050s as during the Cold War. The evolution of counter-detection technologies will not have the same salience in the 2050s as it did in earlier times. As a result, by the 2050s, this assessment shows, progress in counter-detection will only reduce the probability of detection from very likely to likely.
