Safety failure Realized harm

A US Navy unmanned vessel under tow accelerated on an inadvertent command and capsized its support boat, throwing the captain into the water

AIR-2025-0051 AIR record · 2025-06-navy-usv-inadvertent-command-capsize
A real party was affected. This incident caused actual consequences, not a demonstrated capability.
From the supporting source
The Navy stopped a maritime drone test early and urgently requested support from the Coast Guard and local harbor patrol agents to help rescue a participating tugboat captain from waters off the California coast last week, multiple sources told DefenseScoop.defensescoop.com

Curator notes
The one record in the corpus where the failure is squarely at the command interface rather than in perception or planning: an autonomy stack and an onboard control system disagreed about state, and the vessel accepted and executed a throttle command while under tow. No interlock tied 'I am being towed' to 'refuse propulsion commands'. Adjacent to prompt injection in structure — an unvalidated instruction from a trusted channel producing an unsafe physical action — with no adversary involved. AI Incident Database incident 1561.
