Ship signal jamming, a global threat made worse by Strait of Hormuz crisis
The Strait of Hormuz is experiencing a significant increase in navigation signal jamming, leading to dangerous anomalies in global navigation systems. This issue has been exacerbated by the ongoing conflict in the Middle East, with nearly 1,000,000 instances of satellite positioning system interference reported since late February. The MICA Center has identified several regions, including the Baltic Sea and Arabian Gulf, as major hotspots for this interference.
- ▪Global navigation systems are showing increasing anomalies due to navigation signal jamming.
- ▪Since February 28, there have been nearly 1,000,000 instances of satellite positioning system interference in the region.
- ▪The MICA Center identified the Baltic Sea, Red Sea, Black Sea, and Arabian Gulf as major epicenters of signal interference.

Opening excerpt (first ~120 words) tap to expand
Thomas Scalabre, commander of the MICA Center maritime surveillance facility in the Breton city of Brest, outlines the situation in the Strait of Hormuz region, on March 22, 2026. VINCENT GOURIOU A 200,000-metric-ton cargo ship suddenly appeared to be floating down an airport runway. Another seemed to be moving through the desert or dropping anchor beside a nuclear power plant. Global navigation systems have recently displayed increasing numbers of such anomalies, amid a sharp increase in navigation signal jamming, which produces location data errors and raises the risk of collisions. This largely invisible threat has been amplified by the war in the Middle East.
