Anthropic says China-linked actors used Claude for military targeting and torpedo defense work
Anthropic's September 2026 threat report describes Chinese-based actors using its Claude models across at least five programs, including two tied to military applications. One actor drafted fire-control specifications for an anti-torpedo system and benchmarked it against U.S. Navy systems, while another built roughly 16 software modules for suppressing enemy air defenses, with a default scenario targeting 12 sites in Taiwan such as Patriot batteries and air bases. Metadata reviewed by Anthropic suggested links to Chinese research institutions, including the PLA Academy of Military Sciences.
