Alphaliner live satellite vessel tracking shows that 48 container ships in the waters west of the Strait of Hormuz currently have their transponders switched off or are broadcasting spoofed positions, as of March 10.
Disruption in the area reached even higher levels earlier in the month. A record 65 container ships registered lost or manipulated signals on March 4, when the number of vessels with visible and disrupted transmissions was split exactly in half.
Abnormally high levels of signal disruption in the region persisted over the following days, with 62 ships recorded on March 6, 63 on March 7 and 60 on March 8.
For comparison, during the June 2025 twelve-day war, the number of container ships around Hormuz operating with disrupted signals peaked at 32 vessels.
The last container ship recorded leaving the Persian (Arabian) Gulf via the Strait of Hormuz was observed on March 5, a sub-3,000 TEU vessel. Since then, no additional container ships have exited the Gulf.
In total, 131 container ships remain stranded west of the Strait of Hormuz, according to live vessel monitoring, said Alphaliner in a report.
