Phantom Positions and Collision Risks
The oil tanker Front Tyne was navigating the waters between Iran and the United Arab Emirates on Sunday morning when it suddenly appeared — according to ship tracking data — to be in the middle of Russian farmland. Hours later, the same vessel showed up in southern Iran before fluctuating erratically across the Gulf.
This bizarre series of signals reflects a broader phenomenon affecting the region: GPS jamming in the Gulf, a growing threat to maritime navigation systems. Nearly 1,000 vessels have reported similar interference since the outbreak of conflict between Israel and Iran, according to maritime intelligence firm Windward.
Tensions escalated further last Tuesday when two oil tankers collided south of the Strait of Hormuz, one of the world’s most crucial energy chokepoints. Both vessels caught fire. One of them, the Front Eagle — a sister ship to the Front Tyne and nearly 1,000 feet in length — also showed up on tracking systems as being onshore in Iran on June 15, according to Kpler data.
“There is usually no jamming in the Strait of Hormuz — and now there is a lot,” said Windward CEO Ami Daniel. “It’s a hot area… if you don’t geolocate, there’s a bigger chance you’ll have an accident.”
Weaponizing Navigation Disruption in Conflict Zones
Ships rely on AIS (Automatic Identification System) to transmit real-time data about their location, speed, and heading. This system, akin to GPS, is essential for safe maritime operations. But when signals are intentionally disrupted by external sources — a practice known as jamming — crews can lose their ability to navigate safely.
In contrast, spoofing refers to when a ship itself manipulates its AIS data, often to hide illegal activity or evade sanctions.
According to Dimitris Ampatzidis of Kpler, the Gulf region is experiencing widespread jamming — not spoofing — likely driven by military operations aimed at concealing the movements of naval or strategic assets.
“If you don’t know where vessels are, you’re unable to target them,” Ampatzidis said.
The tactic is not confined to the Gulf. Analysts have recorded similar incidents in:
- The Black Sea, during Russian attacks on Ukrainian ports
- The Taiwan Strait
- Off the coasts of Syria and Israel
- Near Port Sudan, where some ships appeared inland last month
- And even India, where the sanctioned tanker Xi Wang Mu spoofed its position to a Hindu temple
The International Maritime Organization and other UN agencies expressed alarm in March over these rising cases of navigational interference.
As reliance on digital systems grows, the maritime sector remains highly vulnerable to such disruptions. Jim Scorer, Secretary General of the International Federation of Shipmasters’ Associations, noted:
“If your GPS is jammed, then you have no real form of navigating other than by the seat of your pants.”
GPS Jamming in the Gulf: Summary
The spike in GPS jamming across the Gulf and beyond is placing global maritime traffic at greater risk. With ships like the Front Tyne and Front Eagle exhibiting erratic and false positions, and with rising military tensions in the region, the threat to safe and transparent navigation continues to grow. As vessels increasingly rely on digital systems, the cost of disrupted geolocation — from collisions to concealed operations — becomes more severe.
