Iran War Shipping Update – June 9, 2026

Since the outbreak of the Iran War on February 28, Iran’s “Ghost Fleet” has continued operating across key maritime routes and continued to load oil. However, since the U.S. blockade initiated on April 13, oil exports have dropped dramatically. UANI observed zero crude shipments passing the blockade during the month of May.

On June 8, U.S. CENTCOM posted that U.S. forces have redirected 134 commercial ships and disabled 7 ships to prevent them from entering or leaving Iranian ports, as well as allowing 42 vessels supporting humanitarian aid to pass since the commencement of the blockade.

The LPG tanker GALVIN (IMO 9387762), both OFAC-sanctioned and listed on UANI’s Ghost Armada, appeared to turn around as it approached the U.S. blockade line and headed back toward the Persian Gulf, according to its AIS broadcast, on June 9. This is at least the second time the vessel has approached the U.S. blockade line and turned around since the start of the blockade. GALVIN is reportedly carrying over 500,000 barrels of Iranian LPG, which it loaded at Assaluyeh Port, Iran, on May 3.

Status of the Strait of Hormuz

The Strait of Hormuz remains a critical flashpoint in the Iran War. Since the start of the conflict, 45 confirmed maritime incidents involving commercial vessels and offshore infrastructure have been reported across the Persian Gulf, Strait of Hormuz, and Gulf of Oman. 

CENTCOM reported that two crew members from a U.S. Army AH-64 Apache were rescued by American forces after their helicopter went down near the coast of Oman on June 8. Today, President Donald Trump blamed Iran for the downing of the Apache helicopter and said the United States would respond.

The enduring risk has created severe congestion and instability across the Persian Gulf’s shipping lanes. Prior to the outbreak of hostilities, about 138 vessels transited the Strait of Hormuz daily. Since March 1, 2026, marine traffic data shows growing clusters of loitering vessels on both sides of the Strait of Hormuz, with many refraining from transiting due to safety concerns.

IRGC efforts to restrict Freedom of Navigation

The IRGC’s newly announced so-called “Persian Gulf Strait Authority” (PGSA) published a proposed scheme for controlling and restricting freedom of navigation through the international strait.  Such measures are in direct contradiction to UNCLOS Article 44, “Duties of States bordering straits,” which states:

“States bordering straits shall not hamper transit passage and shall give appropriate publicity to any danger to navigation or overflight within or over the strait of which they have knowledge. There shall be no suspension of transit passage.”

Any attempt to impose unilateral restrictions on transit passage through an international strait undermines the internationally recognized navigational rights guaranteed under UNCLOS.

The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) took action and designated Iran’s so-called Persian Gulf Strait Authority (PGSA) on May 27.

Iranian Oil-Laden Tankers Inside the U.S. Blockade

UANI has identified at least 73 tankers laden with Iranian oil — primarily crude, but also other petroleum products and LPG — currently operating inside the U.S. blockade line which can be drawn from the Iranian-Pakistan border to the most eastern point of Oman.

Iran-linked Vessels at Kharg Island, Iran

Satellite imagery from June 5 indicates an accumulation of tankers at the Kharg Island anchorage, idle offshore. 22 tankers were spotted in the anchorage area, at least 14 of which are laden with Iranian hydrocarbons which are highlighted in red in the map below. The buildup of tankers anchored here suggests increasing disruption to Iran’s crude export flows due to the ongoing US blockade, particularly shipments destined for China’s independent “teapot” refineries. 

Number of Iranian Loadings

Since the outbreak of the conflict, UANI has tracked at least 81 Iranian oil loadings, 47 of which originated from Kharg Island, Iran. These shipments represent approximately 90 million barrels of Iranian oil, generating an estimated revenue of over $7 billion for the IRGC, which continues to fund Iran’s active missile and drone programs central to the conflict. This figure is notably higher than usual given the sharp increase in oil prices, including Iranian crude.

Iran-linked Vessels at Chabahar Port, Iran

Iran-linked vessels are loitering and anchoring outside of the Persian Gulf at Chabahar Port, Iran. On June 5, 14 tankers, including 11 Iran-flagged tankers and three dark fleet vessels, all laden with Iranian oil indicated by the red squares on the image below, as well as 15 cargo vessels, the majority of which are Iran-flagged, were observed in satellite imagery near Chabahar Port. Many of the Iran-flagged and Iranian oil-laden tankers that have attempted to cross the blockade departed from Chabahar Port, with at least eleven of these returning to port in response to a variety of U.S. enforcement actions. Several of the tankers in this anchorage have shifted locations since late May for unknown reasons, which could indicate an attempt to sail out and test the U.S. blockade before returning in response to enforcement actions.

Iran-linked Tankers at Jask Port, Iran

There is a growing cluster of tankers just east of Jask, Iran. On June 8, eight tankers were observed in the anchorage, six of them laden with Iranian crude. Four of those six laden tankers had moved from an anchorage inside the Persian Gulf near the Greater and Lesser Tunb islands between May 29 and June 3, despite having remained anchored there for more than a month. The red squares indicate laden tankers and white indicates unladen tankers.

Iran-linked Vessels near Sri Lanka

Iran-linked tankers have been anchoring about 20 km offshore from Galle, Sri Lanka, likely for logistical support from local service providers but also in response to pressure from the U.S. blockade. On June 5, four Iran-flagged tankers, all unladen, plus six ghost fleet tankers, one of which carrying Iranian crude which is indicated by the red highlight in the map below, were anchored near Galle. On June 5, the laden tanker DAVINA was interdicted by U.S. naval forces aboard a U.S. Navy expeditionary sea base (T-ESB) which is indicated by the green circle on the satellite imagery below.

Iran-flagged Tankers Globally

UANI has also monitored Iran-flagged tankers operating beyond the Persian Gulf. Since the conflict began, at least 32 Iran-flagged tankers have reached Southeast Asian waters bound for the Eastern Outer Port Limits (EOPL) anchorage off Johor, Malaysia. 

Meanwhile, at least 39 Iran-flagged tankers, reporting empty, have begun attempts to return to Iran and from the Malaysian EOPL anchorage and Southeast Asian sea lanes, since the start of the conflict.

Iran-Oil Laden Tankers off the Malaysian Coast

From February 28, the start of the conflict, to today, UANI has recorded 69 STS transfers of Iranian crude oil and 5 STS transfers of LPG in the EOPL anchorage, a ghost fleet hotspot approximately 70 km off Malaysia’s coast. All of these transshipments have been spotted in satellite imagery.

On June 9, 43 tankers listed on UANI's Ghost Armada were anchored or loitering near the EOPL area with their AIS signals active, demonstrating that ghost fleet tankers continue to operate with impunity across Southeast Asia's sea lanes. 

Iran-Flagged Cargo Ships Globally

Despite ongoing pressure of US OFAC sanctions, approximately 40 Iranian flagged vessels continue to operate openly across sea lanes, ports, and anchorages throughout the Indo-Pacific region. Enhanced pressure from the enforcement of the US blockade on Iran and disrupted access to Iranian ports appears to be affecting vessel schedules and operations on a large scale which has contributed to increased instances of ships pausing and waiting in clusters at anchorages across the region.  A new pattern of cargo ships coming from Russian and Libyan ports to Southeast Asia is emerging. There is a growing risk of Iranian flagged cargo ships carrying contraband cargo in violation of US blockade.

Multiple Iranian flagged tankers and cargo vessels continued to anchor offshore of Karachi, Pakistan. The cargo ships ARIES (IMO 9369722), MAHNAM (IMO 9213387), DELRUBA (IMO 9305207) and WARTA (IMO 9465849) were broadcasting on AIS while anchored about 60km offshore in the Pakistani Exclusive Economic Zone (EEZ). The tankers STREAM (IMO 9569633), HERBY (IMO 9362059), SOBAR (IMO 9221970) and SARAK (IMO 9226968) are also anchored nearby. The container ship TOUSKA (IMO 9328900) remained anchored just 16 km outside Karachi port, inside Pakistani territorial waters. All of these Iran-flagged vessels are OFAC sanctioned. At least 10 other non-Iranian flagged Ghost Armada tankers are also anchored in the Pakistan EEZ.

The Iran-flagged general cargo ship AREZOO (IMO 9165786) continued to sail in the Andaman Sea toward Chittagong, Bangladesh, with an estimated arrival of June 9. It briefly pinged on AIS near Myanmar on June 8 but has not yet appeared near Bangladesh.

The Iran-flagged bulk cargo ship KIAZAND (IMO 9465758) continued to sit at anchor, approximately 35km south of Phuket, just outside Thai territorial waters.

The Iran-flagged container ship NORA (IMO 9259408) loitered in the northern part of the Malacca Strait, about 90km west of Penang, and today began drifting slowly southwards. The container ship is reporting its destination as Port Klang, with an estimated arrival of June 10.

The ALOR 2 (IMO 9228538) continued to sail south in the northern part of the Malacca Strait, and is reporting its destination as Singapore, with an estimated arrival of June 11.

Both NORA and ALOR 2 previously departed Misrata, Libya in late May, and are also OFAC sanctioned.

The Iran-flagged general cargo ship RADIN (IMO 9820257) remained anchored outside Port Klang in the Malacca Strait.

On June 9, the container ship NYRA 2 (IMO 9241487) was still berthed at Westport Container Terminal.  NYRA 2 departed Misrata, Libya on May 17, after unknown cargo operations, and visited the Malaysian EOPL for approximately 24 hours over June 4 and 5.

Both Iran-flagged cargo ships are OFAC-sanctioned, so it is possible that the commercial port operator at Port Klang is openly disregarding the risk of U.S. OFAC secondary sanctions.

Five OFAC-sanctioned, Iran-flagged cargo ships remained in the Malaysian EOPL anchorage area, openly broadcasting on AIS. The cluster of vessels include bulk cargo ships ARVIN (IMO 9193202), MIAMI PRIDE (IMO 9274941), ANDIA (IMO 9193197), and the container ship OURA (IMO 9387815). The bulk cargo ship BASKAR (IMO 9405942), maneuvered to a new location west of the EOPL, and was drifting, for unknown reasons. These vessels are all likely waiting in the EOPL due to the U.S. blockade.
