More Than 1,100 Ships Hit by Widespread GPS Disruption After Iran Strikes

A surge of maritime GPS and AIS interference affected over 1,100 vessels across the Gulf within 24 hours of the Feb 28 U.S.-Israel strike on Iran, with Windward and Lloyd’s identifying numerous new jamming clusters and widespread false vessel positions on land, airports, and sensitive sites. The activity—assessed as intentional, broad-area jamming/spoofing—poses serious navigation and compliance risks and may be linked to regional efforts to disrupt potential Iranian strikes, marking a rapid escalation in intensity and geographic spread of GNSS/AIS interference.
