Using AI for Weapons Development
A group of threat actors based in northern Yemen are utilizing AI, specifically Anthropic's Claude models, to develop advanced weapons systems, including guided rockets and ballistic missiles. Despite security measures, the actors successfully employed AI to bypass safeguards and create complex guidance software, demonstrating a concerning trend of AI being weaponized by malicious actors. The group’s efforts highlight the growing risk of AI-assisted development in the defense sector.
A group of threat actors operating in northern Yemen are leveraging artificial intelligence, using Anthropic’s Claude models, to develop sophisticated weapons systems. These systems include a guided rocket utilizing a commodity phone-class flight computer for final-phase homing guidance, a multi-stage ballistic missile with a range exceeding 2,000 km, and a multi-variant missile known as the ‘R2000’ set, incorporating a hypersonic glide vehicle variant. The actors utilized Claude Code to develop the guidance, navigation, and control (GNC) software necessary to steer and stabilize these flying vehicles. Specifically, they integrated an open-source autopilot onto the flight computer, writing the control and position estimation software, tuning control settings, and performing flight simulations. The actors managed multiple Claude instances concurrently, assigning roles similar to a small engineering team – one instance for coding, another for research, and a third for code review. Despite security measures in place, the actors employed various tactics to evade detection, including obscuring their goals and splitting their work across multiple sessions. Notably, they conducted a field test of a guided rocket, which subsequently failed, prompting the actors to return to Claude to troubleshoot the issue. While the actors did not succeed in fielding a fully operational weapon, their sustained efforts and use of AI for weapon development represent a significant and concerning trend.
