The article discusses the UK’s plans to use artificial intelligence (AI) and undersea cables to track Russia’s ‘shadow fleet’ of submarines and ships by 2025. The UK is leading a coalition of countries, including the US and allies, to develop an AI-powered system that can detect and monitor Russian naval activity. The system will utilize undersea cables to gather data, which will be analyzed by AI algorithms to identify and track Russian vessels. This initiative aims to counter Russia’s increasing naval presence and potential threats to undersea infrastructure. The coalition plans to have the AI system operational by 2025, providing enhanced maritime domain awareness and improving the ability to respond to potential Russian aggression. The article highlights the growing importance of AI and undersea cable networks in modern naval warfare and intelligence gathering.
