Abstract: The article argues that India and the United States are poised to strengthen their bilateral strategic convergences, not only in the Indian Ocean but also in Pacific-Asia that lies eastwards of the Malacca Straits, and wherein India’s geo-strategic stakes as well as its military-strategic footprint are likely to increase in the coming years. This would progressively enhance the complementarities between their navies in the western Pacific and its contiguous seas, thereby enabling substantive naval cooperation towards ensuring security and stability in the broader Indo-Pacific region. Introducing the theoretical concept of ‘geo-strategic frontier’, the article examines the various factors at play and conceives the likely future scenarios of ‘high-end’ India–US naval cooperation in Pacific-Asia, in the short-, medium- and long-term timeframes
