US Central Command redirects 62 vessels, disables three as Iran naval blockade intensifies
CENTCOM's enforcement numbers climb as the second phase of the Iran maritime blockade enters its fifth week
The US Navy is not operating quietly in the Arabian Sea. As of August 14, US Central Command has redirected 62 commercial vessels, disabled three, and boarded two since reinstating its naval blockade against Iranian ports on July 14, 2026.
How the blockade actually works
CENTCOM has deployed a combination of aircraft carriers, helicopters, and surface vessels to intercept ships attempting to reach or depart Iranian ports through the Arabian Sea and the Gulf of Oman. When a vessel ignores warnings to divert, US forces have the authority to disable it, including through the use of Hellfire missiles. Three ships have reached that threshold so far in this enforcement phase.
Boarding actions, which involve US personnel physically taking control of a vessel, have occurred twice. These are the most operationally intensive interventions and signal direct non-compliance that goes beyond simply ignoring radio warnings.
Humanitarian aid vessels are exempt from the restrictions. CENTCOM has maintained that protocol consistently across both enforcement phases, preserving some movement through the Strait of Hormuz for ships carrying food, medicine, and other aid cargo.
The blockade’s history in two acts
The first enforcement period ran from April 13 to June 18, 2026. During that stretch, 67 vessels were redirected, and more than 140 vessels were redirected in the first month alone. Humanitarian shipments were cleared for passage throughout that period as well.

A ceasefire agreement paused the blockade through late June and into early July. When that agreement collapsed, CENTCOM reinstated enforcement on July 14.
President Donald Trump framed the blockade as a mechanism for limiting Iran’s maritime trade as part of a broader pressure campaign. The strategy targets vessels specifically linked to Iranian ports rather than all shipping in the region.
What the numbers mean for the region
The Strait of Hormuz remains one of the most strategically sensitive chokepoints in global energy logistics. Roughly a fifth of the world’s oil supply passes through it under normal conditions.
CENTCOM has been updating its figures regularly through official channels and social media, which is itself a deliberate signaling strategy. Publishing running tallies of redirections, disablements, and boardings serves notice to shipping operators globally about the operational tempo and seriousness of enforcement.
