Ranking the Naval Blockade's Toll: 12 Vessels Redirected, 1 Disabled in Nine Days

The US naval blockade of Iran is back, and in nine days it has already become one of the most kinetic maritime enforcement operations since the Tanker Wars.

On July 23-25, U.S. Central Command gave the same baseline stat across multiple updates: "Since resuming the naval blockade against Iran nine days ago, CentCom has redirected 12 commercial vessels and disabled 1 to prevent ships from entering or leaving Iranian ports or coastal areas."

By July 25, that number was refined: by July 25 it had redirected 12 commercial vessels attempting to reach Iranian ports, disabled two vessels that failed to comply with repeated warnings, and conducted verification boardings of two others.

Whether you count 1 or 2 disabled, the operational tempo is unprecedented for a blockade that was only re-imposed after the collapse of a short-lived memorandum of understanding from mid-June.

#### The 9-Day Toll - Ranked by Severity

1. The 12 Redirected - The Economic Weapon

This is the core of the blockade. Twelve commercial vessels attempting to reach Iranian ports were redirected. This is not a warning - it's a forced turnaround.

CENTCOM has been clear on intent: The blockade aims to economically pressure Iran by restricting its oil exports and imports through its ports.

Each redirection is a lost cargo, a broken charter party, and a spike in war-risk insurance. With 10 ships turned back in the first 48 hours alone, the early rate was 5 ships per day.

> "Ten vessels have now been turned around, and ZERO ships have broken through since the start of the US blockade on Monday," CENTCOM posted on day two.

2. The 1 (or 2) Disabled - The Escalation Signal

The disabling is where this blockade separates from a sanctions enforcement patrol.

Two cases have been named:

* M/T Lavine (Mozambique-flagged): CENTCOM confirmed action against the Mozambique-flagged tanker M/T Lavine, stating that US forces disabled the vessel in the Gulf of Oman after its crew allegedly ignored multiple warnings and repeatedly attempted to breach the blockade. The ship is no longer transiting to Iran.

* The Second Disabled Vessel: Multiple July 25 reports list a second vessel disabled after ignoring repeated warnings, including actions like precision strikes on engine rooms.

In CENTCOM language, "disabled" does not mean sunk. It means a non-lethal strike to stop propulsion - typically to the engine room or rudder - after repeated warnings.

3. The 2 Boarded - The Compliance Check

One of the vessels boarded was the Comoros-flagged tanker M/T Charminar, which was inspected in the Arabian Sea before being cleared to continue its voyage.

Boarding + clearance is crucial. It proves the blockade is not a blanket ban - it's a verification regime. Pass inspection, you go.

Why 12+1 in 9 Days Matters

In historical context:

* June 2026 peak: 121 commercial vessels redirected, 5 vessels disabled. That was over several weeks.

* This resumption: 12 redirected in 9 days puts it on pace for 40 per month - a slower but more selective enforcement than June, but with a higher disable rate.

The blockade remains fully operational, with US naval forces redirecting, boarding, and disabling ships suspected of violating restrictions.

The message to the tanker market is simple: The Strait of Hormuz is open, but Iranian ports are not. For traders, the toll is not just the 12+1 ships. It's the 100+ that never left port in the first place because they saw the post on X.
