GPS Jamming in the Persian Gulf: A New Threat to Global Shipping

A few months ago, back in November, I was swimming in the beautiful waters of the Persian Gulf in Kish, enjoying its pearl-white beaches.

I would not have ever imagined that the very waters I was swimming in are now part of one of the most sophisticated electronic battlefields in the world. Hundreds of commercial vessels in and around the Strait of Hormuz are sending GPS positions that don’t make sense. Some appear in perfect clusters, others seem to be sailing on land.This is not a navigation glitch. This is electronic warfare.

Maritime analyst Michelle Wiese Bockmann from Windward has identified 35 separate clusters of vessels with distorted positions in the Gulf. Ships rely on GPS and AIS systems to avoid collisions. When those signals are disrupted, the risks grow fast. Collisions become more likely, navigation becomes unpredictable, and logistics, insurance, and energy markets are all affected.

Even a 300-meter oil tanker cannot stop or turn quickly. Any misalignment in positioning can lead to serious consequences.

GPS disruption is not a new thing. It has been seen in Eastern Europe, the Baltic Sea, and even in Europe’s airspace. But now the Middle East is entering a new phase of signal warfare.

Solutions are emerging. Anti-jamming antennas like Raytheon UK’s Landshield, GPS-independent navigation using gyroscopes, accelerometers, optical terrain matching, satellite imagery, and even star mapping, like the work of Advanced Navigation. Using multiple sensors is no longer optional. It is essential.

From a cybersecurity and critical infrastructure perspective, this is a supply-chain attack on marine shipment of oil. Modern maritime operations depend on signal accuracy and timing. When those fail, the consequences ripple across industries, infrastructure, and economies.

The oceans are becoming a digital battlefields. The next maritime incident might not start with a missile. It might start with a coordinate that is slightly wrong.

For anyone managing maritime operations, energy logistics, or critical infrastructure, the question is simple. How resilient is your navigation system?
