Anthropic just published what might be the most unsettling AI safety document to date: a 154-page threat intelligence report detailing how a group of Russian developers used Claude Code to build software for autonomous kamikaze drones designed to identify targets and detonate without human input.
The project, internally designated DronDoc or Serafim and tracked by Anthropic as GTG-27005, was designed to give attack drones the ability to select targets, distinguish between friendly and enemy forces, and execute terminal guidance maneuvers, all culminating in an autonomous detonation command. No human in the loop for the final kill decision.
What the developers actually built
According to Anthropic’s report, released on September 11, 2026, the Russian developers began work on the project around mid-May 2026. They leveraged Claude Code, Anthropic’s AI coding assistant, to develop a suite of capabilities that reads like a military contractor’s wish list.
The software incorporated a computer vision classifier trained on Ukrainian combat footage, with a particular focus on the Donetsk region. It could perform target selection, including the ability to differentiate between what it classified as “enemy” and “friendly” targets, and it featured terminal guidance systems for the final approach phase.
