As artificial intelligence (AI) continues to reshape the global security landscape, a new report by Kenneth Payne for the Royal United Services Institute (RUSI) outlines both the transformative potential and urgent challenges of integrating AI into the UK’s national defense infrastructure.
Titled AI and National Security: Risks and Opportunities for the UK, the March 2025 publication emphasizes that AI, much like electricity or the steam engine before it, is a general-purpose technology with vast implications across society—including defense. From autonomous drones and AI-assisted cyber defense to predictive analytics in intelligence gathering, the report details how AI is already altering strategic operations and battlefield tactics.
The UK faces a critical juncture. AI’s unmatched strengths in pattern recognition, decision speed, and data synthesis can deliver strategic advantages. But they also pose risks. Autonomous decision-making in combat scenarios raises ethical and accountability concerns, while adversaries deploying less constrained AI systems could disrupt norms the UK aims to uphold.
Payne explores intersections between AI and other emerging technologies—quantum computing, hypersonics, space systems, and biotechnology—that could accelerate defence innovation but also expand the threat surface. Tactical applications, such as AI-powered drones and battlefield management systems, are already influencing conflicts from Ukraine to Gaza. However, the report warns of a growing unease about “killer robots” and the erosion of human oversight in high-stakes environments.
Beyond the battlefield, AI is transforming intelligence operations and strategic planning. The UK’s Government Communications Headquarters (GCHQ) uses AI for cyber defense, while companies like Palantir and Hadean provide synthetic environments for crisis simulations.
Despite this, adoption in defence remains slow. The report highlights barriers including outdated military structures, a shortage of AI-skilled professionals, and the UK’s reliance on foreign tech firms for frontier research and infrastructure. Maintaining strategic autonomy will require significant investment in domestic innovation, ethical AI governance, and international regulatory leadership.
Looking ahead, Payne urges policymakers to prepare for artificial general intelligence (AGI), which—if developed—could redefine power dynamics and escalate global risks. The UK must balance innovation with caution, ensuring AI enhances rather than undermines security, democratic norms, and public trust.
As Payne concludes, the future of AI in national security is not just about tools—it’s about values, strategy, and leadership. The clock is ticking.
