Anthropic, the U.S.-based AI company, disclosed in its Intelligence Threat Report that an actor group in northern Yemen attempted to use its Claude AI model to develop military guidance software for rocket systems.[^1]

The September threat report describes a cell in northern Yemen that used the company's Claude Code to develop software for guided rockets, a long-range ballistic missile, and a hypersonic glide vehicle.[^2] The group test-fired a guided rocket in Yemen, which failed, and then used AI to analyze the telemetry data to investigate the failure.[^3] The cell, controlled by Houthis, used Claude Code to develop guidance, navigation, and control software for a guided rocket, a multistage ballistic missile, and an R2000 hypersonic glide vehicle variant.[^4]
