This article reflects on the dynamics that underlay the circulation of military technology during the early modern phase of globalization. The debate on the development and transfer of gunpowder weaponry has been dominated by a grid of analysis which implicitly puts value on sovereign production and direct state control over the resources used for war. Focusing on the transfer of naval artillery between Europe and Asia, the article argues for the need to expand the scope of analysis of the contractor state, so far centred on Europe, and study the potential world-scale of the market for naval resources and services in the period between 1500 and 1750. It also highlights the need to replace the reading of technological transfers centred on nation-states by a more fluid and transnational vision which articulates the demand stemming from both states and non-state actors and the rise of regional clusters specialized in providing naval technology with competitive levels of prices, in an age of increasingly interconnected maritime economies. Therefore, the article aims to show why naval artillery, despite being a protagonist of old imperialistic narratives, is still a relevant object of study for the agenda of global history.
