Global Underwater Hub (GUH), the trade and development body representing the UK’s £9 billion (approximately 12.2 billion) subsea sector, has called on the Ministry of Defence (MoD) to overhaul its approach to underwater defence and begin working directly with commercial subsea companies to counter rising threats.

The statement follows the release of the UK government’s 2025 Strategic Defence Review. GUH argues that outdated MoD procurement models are no longer fit for purpose, given the rapidly evolving nature of threats facing the country.
