Houthis Used Claude Code to Develop Missile Guidance Software: Anthropic
Anthropic has reported that Houthi rebels in Yemen utilized its Claude Code AI tool to assist in the development of missile guidance software and hypersonic glide vehicle concepts. The report highlights how generative AI can be used to compress complex engineering workflows for conventional weapons development.
Why it matters
This incident demonstrates a significant security risk regarding the dual-use nature of generative AI in military and weapons development.
Anthropic says operators in northern Yemen ran parallel Claude Code instances to design guidance software, simulate trajectories, and analyze a failed rocket test, effectively compressing specialist missile-engineering work into an AI-assisted workflow.

A cell in northern Yemen used Anthropic’s Claude Code to perform work that would ordinarily require a missile engineering team, developing software for guided rockets, a long-range ballistic missile and a hypersonic glide vehicle concept.
Anthropic’s September threat report describes operators running several Claude instances at the same time, dividing tasks between coding, research and technical review.
