The disclosures point to a national security risk created by heavy reliance on a private satellite network.

Overview

  • Internal Navy documents reviewed by Reuters tie multiple autonomous-boat test disruptions to Starlink connectivity losses.
  • During August 2025's global Starlink outage, about two dozen unmanned surface vessels off California lost contact for almost an hour.
  • A Navy safety report from April 2025 said high data needs for many vehicles strained the link and flagged limits under multi-vehicle load.
  • The Pentagon described its broader network as a mix of resilient systems but gave no details on changes to prevent repeat failures.
  • SpaceX's near-10,000-satellite network and launch dominance keep it central to U.S. programs as Congress warns about single-vendor risk and Amazon moves to buy Globalstar.
