Current Navigation Crisis in the Strait of Hormuz and Persian Gulf
Thousands of vessels presumed missing in the Persian Gulf due to navigation mishap
Navigational systems on over 900 vessels have been experiencing serious failures in the Strait of Hormuz and the Persian Gulf. With tankers, fishing vessels, and cargo ships displaying peculiar patterns on maps - like straight lines, zigzags, and movements on land - there's a growing concern about GPS signal interference.
According to recent reports, intense GPS signal jamming is originating from Iran's port of Bandar Abbas. This coincides with the escalating tension between Iran and Israel, although no signs yet of an impending blockade of the Strait of Hormuz have been detected [1][4].
As a result of these signal disruptions, captains are being forced to revert to traditional navigation methods like radar and compasses, increasing the danger of accidents. Some shipowners have even refused to enter the gulf, prompting a spike in insurance rates for oil transportation from the Middle East to Asia by 12% [1].
It's worth remembering that Iran was responsible for hacking Israel's air defense system [2].
Key Locations and Incidents
The Strait of Hormuz appears to be a hotspot for GPS interference. Suspected jamming can even cause ships to stray into Iranian waters, potentially leading to seizures [2]. On May 18, 2025, the UK Maritime Trade Operations reported GPS interference impacting several vessels [2].
One of the most recent incidents occurred on June 17, 2025, when the Liberia-flagged VLCC Front Eagle faced GPS jamming while transiting the Arabian Gulf and the Strait of Hormuz. The vessel's AIS signals led it close to Iran's Asaluyeh port, culminating in a collision with another tanker. While the collision wasn't directly attributed to hostile activities, GPS jamming was identified as a contributing factor [3][5].
Maritime Navigation Risks
GPS interference poses multiple dangers for safe navigation in busy maritime corridors like the Strait of Hormuz, such as:
- Collision Risks: Accurate positioning is vital for collision avoidance. GPS disruptions can lead to navigational errors, particularly in areas with high traffic volumes and complex traffic schemes [3].
- Voyage Planning: Disruptions to GPS can hinder the ability to properly plan and execute safe voyages, potentially complicating adherence to established maritime routes and schedules [3].
- Global Trade Impact: The Strait of Hormuz is a vital artery for global energy security, transporting over 20% of the world's oil and gas. GPS interference can have significant implications for energy markets and global trade stability [3].
Ongoing Worries
The growing frequency of GPS interference incidents underscores the necessity of reinforced maritime security and vigilance in the region. With geopolitical tensions on the rise, the likelihood of such disruptions is heightened, jeopardizing the safety and efficiency of maritime operations [1][4].
