RUSI’s annual Military Technology Conference, held in London in October, presented a comprehensive picture of the technological revolution underway in the British Army and in other European militaries—a transformation that reflects the Russian threat and operational lessons emerging from the war in Ukraine. Future force design is transitioning sharply from hardware-centric to AI-driven and autonomous systems, with the strategic objective that by 2035, most combat platforms will be unmanned. Along with announcing massive investments and flagship programs, the conference identified key obstacles: bureaucratic delays, gaps between civilian AI and battlefield requirements, and legal and ethical challenges associated with integrating autonomous systems. The conference highlighted lessons learned from the war in Ukraine in shaping European military analysis, yet scarcely addressed the many lessons to be learned on Middle Eastern battlefields. The conclusion: Britain is undergoing a profound conceptual and operational shift, but its success will depend on overcoming structural barriers, accelerating innovation, and transforming advanced technological capabilities into effective military power within a short time frame.
