The development of uncrewed maritime vehicles [UMVs] has the potential to increase the scale of military maritime surveillance in the exclusive economic zones of foreign coastal states. This paper considers the legal implications of the expanded use of UMVs for this purpose. It shows how features of the legal regime—namely how its application depends on determining the intent of a vessel's operation (to distinguish marine scientific research from military surveillance), as well the obligation to have due regard—have a “dynamic” quality that will pose a challenge to UMVs operated by autonomous technology. The legal obligations will require equipping UMVs with the capacity to communicate something about their identity, the purpose of their mission, and to be able to have some capacity to be responsive to the economic and environmental interests of the coastal state.

However, this paper focuses on UMVs used for this activity in order to consider their use for this specific purpose.

There are twelve provisions in UNCLOS that use a “due regard” obligation (UNCLOS, supra note 1 at arts. 27(4), 39(3)(a), 56(2), 58(3), 60(3), 66(3)(a), 79(5), 87(2), 142(1), 148, 234, 267), and a further two that use the synonymous phrase “reasonable regard” (UNCLOS, supra note 1 at arts. 147(1), 147(3)) The drafting history supports the conclusion that the terms basically mean the same thing. Oxman, supra note 96 at 827 explains that the change was due to a “retranslation of the Spanish term ‘debida consideración’ (which is the Spanish equivalent of ‘reasonable regard’ in the Convention on the High Seas) as ‘due regard’ or ‘due consideration’” in the proposed texts that were drafted by the Spanish-speaking delegates.
