Ship Clusters and Speeding Tankers Point to Hormuz Jamming

At least a dozen ship clusters have appeared near the Strait of Hormuz, a likely sign of electronic interference around the waterway through which most transit has halted with the US and Israeli war against Iran.

The groups, which can number more than 200 vessels for some clusters, contain ships of all types, with some that appear to be traveling at more than 100 knots, according to tracking data compiled by Bloomberg.
