A Gulf in Crisis: Maritime Fallout of the Iran Attack

This analysis was produced by Windward’s Maritime Intelligence Operations Center (MIOC) — a mission-critical operations center powered by Windward’s maritime intelligence experts, operating as a seamless extension of your team. This is a sample of what we deliver. For intelligence tailored to your operational theater, visit the MIOC page.

What Happened 

Coordinated U.S.-Israeli strikes on IRGC command centers and missile production facilities in Tehran, Isfahan, Qom, and Kermanshah have triggered the most severe maritime disruption in the Arabian Gulf since the 1988 Tanker War. Iran’s retaliatory “Operation True Promise-4” is now targeting U.S. military installations across Qatar, the UAE, Bahrain, and Kuwait. The consequences for global shipping are already visible in the data.

Current Operational Picture

Arabian Gulf: Dark Activity at Record Levels

Windward data recorded 464 dark activity incidents per week in the Arabian Gulf in early February — a monthly high. As of tonight, the MIOC is observing a total blackout of AIS signals in the vicinity of the Strait of Hormuz.

Despite this, Windward Remote Sensing Intelligence (SAR-derived vessel tracking) indicates that export traffic through the Strait remains broadly unchanged. Comparing satellite imagery from tonight against 14 February, ships are still moving. Vessel throughput has held a steady trend throughout the month.

The divergence between a total AIS blackout and continued physical vessel movement is itself a significant intelligence indicator. It suggests a combination of deliberate signal suppression by regional actors and precautionary AIS shutdowns by commercial operators entering an active conflict zone.

Red Sea and Bab el-Mandeb: Zero-Transit Zone

The Bab el-Mandeb Strait has effectively become a zero-transit zone for Western-linked commerce.

In the immediate aftermath of the strikes, major container lines finalized emergency protocols to keep all vessels clear of the corridor. A.P. Moller-Maersk, MSC, and Hapag-Lloyd activated standing contingency plans. CMA CGM and the Ocean Alliance — notably COSCO and Evergreen — issued urgent notices declaring the Red Sea “non-navigable” due to the risk of misidentification or retaliatory targeting.

Windward data already shows a notable decrease in commercial vessels transiting the Bab el-Mandeb.

UAE Anchorages: Mass Re-Routing Underway

Windward’s early anomaly detection has flagged an all-time high in vessels changing their stated destination while anchored in UAE waters, a 169% spike above baseline. This indicates a large-scale, real-time re-routing of vessels originally destined for ports within the Gulf.
