What happened

The British military is deploying AI technologies to reshape air, sea, and land operations. Britain allocated over one billion dollars to build a 'digital targeting network' integrating military and civilian data in a single command system to enable faster and more precise decision-making on intervention or response.

The military uses the AI-powered 'Domain I' programme to monitor ship movements, submarine cable routes, and detect potential maritime threats, allowing operators to send drones or ships to intercept threats semi-automatically. The programme was developed by British company Hadean, which transitioned from gaming to military AI applications.

In November, British Marines conducted training using AI to deploy swarms of drones operating as a single unit. Britain invests approximately two billion dollars annually in the 'Global Combat Aircraft' programme, a sixth-generation fighter to be developed with Japan and Italy by 2042 to operate alongside drones.

Reported impact

The expanded reliance on AI raises questions about machines' ability to discriminate between combatants and civilians. Jessica Dorsey from the University of Utrecht stated that humans ultimately bear responsibility for ensuring compliance with international humanitarian law.

Index analysis

Former British General Richard Barrons described AI as 'the backbone of the entire military structure' and stated it will soon be central to targeting operations, enabling faster information processing and decision-making under pressure.

Governance controls

Jessica Dorsey emphasised that humans remain ultimately responsible for ensuring compliance with international humanitarian law.
