Dark Fleet Operations¶
Status: Active workaround — government-owned vessels operating with AIS disabled, lights off, radio silence to transit near Hormuz.
What Is the Dark Fleet¶
The "dark fleet" refers to tankers that are deliberately operating with their Automatic Identification System (AIS) transponders turned off — going "dark" — to avoid detection while transiting near the Strait of Hormuz. This is distinct from the standard dark fleet used to describe Iranian and sanctioned vessels evading US sanctions; here it describes Gulf state and other non-Iranian tankers avoiding Iranian targeting and IRGC toll collection.
Operational Profile (June 2026)¶
| Parameter | Detail |
|---|---|
| AIS | Disabled |
| Navigation lights | Off |
| Radio | Silent |
| Radar use | Minimized |
| Time of transit | Nighttime |
| Route | Omani coastal route (outside Iranian territorial waters) |
| Coordination | US Navy (Project Freedom) |
| ~15 vessels/day using the route (INTERTANKO advisory) |
Who Is Operating Dark¶
According to Larry Johnson, head of freight at Mercuria Energy Group:
"They're mainly or exclusively government-owned ships that are making it through. These vessels seem to have channels of communication and means of securing safe passage somehow, some way."
Specific confirmed operators:
- Kuwait Oil Tanker Co. — at least two supertankers (2M bbl each) crossed Hormuz late May, signaling off Kuwait coast with no AIS broadcast since crossing
- ADNOC (Abu Dhabi National Oil Co.) — moved crude through Hormuz with transponders off to avoid detection
Scale¶
- ~2 mbd now flowing out of the Gulf (Rapidan Energy Group) — far below normal but significantly higher than early conflict
- Prices dropped ~30% from wartime peak — dark fleet workaround is the primary reason oil isn't at $200/bbl
- 12 STS transfers on June 6 alone with non-Iranian Middle Eastern barrels (TankerTrackers)
- 16 tankers clustered off Oman for STS transfers over the weekend of June 6–8
Why Government Ships Only¶
Private vessels cannot obtain war risk insurance at commercial rates for the Omani route. Only government-owned or government-backed vessels can make the dark transits because:
1. State insurance backstop (DFC $40B pool)
2. State communication channels with US military
3. State liability protection
Relationship to Existing KB Concepts¶
- project-freedom — US Navy coordination enabling dark transits
- sts-transfer — STS mechanism that offloads cargo from dark fleet vessels
- hormuz-tanker-loop — empty tanker return through the Strait to reload
- dfc-war-risk-insurance — financial backstop enabling participation
- irgc-toll — IRGC toll system that dark fleet avoids
