Artificial intelligence is becoming increasingly central to warfighting. And the firms that build it are critical partners to militaries around the world. Once such company is Britain’s Faculty AI, whose head of defence Andrew van der Lem joins us this week. The conversation covers electronic warfare and the competition to dominate the electromagnetic spectrum; how AI can identify, classify, and act on signals no human could process in time; and the acceleration of military decision-making—a factor in US operational superiority during the recent war in the Middle East.  Andrew also draws on lessons from Ukraine, where new technology hits the battlefield every few weeks and doctrine has to adapt in real time. And he describes a major NATO exercise Faculty took part in — preparing allied forces for a potential Russian invasion of Estonia, run out of a disused London tube station. Finally, Andrew addresses the values question: why Faculty believes tech companies have a responsibility to engage with defence AI rather than leave it to others.
