The US naval blockade of all Iranian ports and coastal areas took effect at 20:00 UTC on 14 July (4pm ET; midnight 15 July Gulf time), interdicting all vessels bound for or departing Iranian ports while permitting neutral transit of the strait to non-Iranian destinations. CENTCOM had announced the blockade a day earlier, on 13 July. More than 20 US warships were reported operating in the region to enforce it.
