Iran poses a major threat to freedom of navigation and maritime security around the world. Iran uses the Islamic Revolutionary Guard Corps’ Navy (IRGCN) to challenge global economic security and the broader regional security architecture. Iran has used international shipping companies to transport illegal weaponry for the purpose of building and sustaining its terror proxy networks in the Middle East. It has also attacked commercial vessels and taken vessels hostage to extract concessions from the international community.
Iran’s malign behavior in this sphere prompted the U.S. Department of Transportation’s Maritime Administration to issue numerous advisories with warnings for merchant vessels operating in the Persian Gulf, Strait of Hormuz, Gulf of Oman, Arabian Sea, Gulf of Aden, Bab al Mandeb Strait, Red Sea, and Western Indian Ocean.
Notwithstanding the adoption of the Joint Comprehensive Plan of Action (JCPOA) in 2015, which Obama administration officials believed would moderate the behavior of the Iranian regime, Iran continued to violate U.S. and E.U. sanctions, and U.N. Security Council resolutions in smuggling weapons and other illicit materials to Lebanon, Syria, Yemen, and Somalia via sea. To this day, the Iranian weapons shipments continue, as do dangerous and hostile actions taken by Iranian naval vessels against international commercial ships, and the U.S. Navy and Coast Guard. In addition, the Persian Gulf has become a theater in which Iran frequently carries out unmanned aerial vehicle (UAV), mine, and missile attacks on Israeli-linked vessels. Foreign shippers, therefore, risk the safety and well-being of crew members when transiting in international waters near Iran.
Since the Trump administration withdrew from the JCPOA in 2018, the U.S. government expanded sanctions on the Iranian shipping sector. For example, on October 26, 2020, the U.S. Treasury Department sanctioned the National Iranian Tanker Company (NITC), which operates a fleet of oil tankers in coordination with and to the financial benefit of the sanctions-designated Islamic Revolutionary Guard Corps (IRGC) Quds Force. Yet, oil revenue continues to fund the IRGC’s Quds Force as well as Iranian-backed proxies throughout the region, such as the Houthis and Hezbollah.
The IRGC is not only deeply involved in the shipment of oil, but the operation of Iranian ports. IRGC-owned companies, such as Tidewater Middle East Co., operate some of the most lucrative Iranian ports, including the Shahid Rajaee Container Terminal at Bandar Abbas Port, where 1.14 million 20-foot containers were loaded and unloaded between March 21 and November 6, 2021. During that time, 20.3 million tons of oil were exported through this port. Given that the IRGC owns Tidewater, the company was sanctioned in 2011 and continues to be sanctioned by the U.S. Treasury Department.
As the layers of ownership are deliberately made endlessly complex, the IRGC has masked its involvement in the Iranian shipping sector, leading international shippers to risk paying loading, docking, and other port fees to an internationally sanctioned terrorist group. Furthermore, foreign shipping companies risk unwittingly becoming entangled in shipments of oil, weapons, or other illicit materials when they choose to do business in the Iranian shipping industry. In order to halt these shipments and revenue streams, international shippers must cease their business with Iran, and the Biden administration should sanction any entity that continues to do business in the Iranian shipping industry, in violation of U.S. sanctions.
This report documents 28 specific instances in which the IRGCN hijacked, abducted, or seized seafaring vessels on international waters; 30 interdictions of Iranian weapons or drugs at sea; 24 unsafe and unprofessional maneuvers by the IRGCN in close proximity to U.S. Navy vessels; 13 IRGCN UAV, missile, or mine attacks at sea; 14 Iran-backed Houthi attacks at sea; and other high-profile instances of Iran menacing maritime channels and exploiting the shipping industry to nefarious ends. In this report, United Against Nuclear Iran (UANI) identifies 27 shipping companies that have either been the victim of Iranian machinations at sea or were involved in shipping illicit cargo to or from Iran. Some of these companies were victimized by or provided aid to Iran on multiple occasions.
The following graph depicts on a year-by-year basis the total number of instances in which Iran threatened maritime security from 2016 to the present. It is noteworthy that vessel seizures increased markedly in 2019, the same year in which the U.S. ended the significant reduction exemptions (SREs), which allowed for certain countries to import limited amounts of Iranian oil. Moreover, Iranian maritime threats more than doubled between the final year of the Trump administration to the first year of the Biden administration. Over the Trump administration’s four years in office, there were a total of 52 incidents; compared to a total of 43 incidents in just under a year and a half since Biden took office. Such an increase in maritime threats corresponded with an increase of Iranian or Iranian-backed attacks on American ground forces stationed in the Middle East.

The Islamic Revolutionary Guards Corps Navy (IRGCN) seized two Greek tankers in the Persian Gulf in retaliation for a U.S. seizure of Iranian oil from the Iranian-flagged Pegas, which Greek authorities had first impounded off the Greek coast due to European Union (E.U.) sanctions. It was unclear whether Greece impounded the cargo because it was in violation of sanctions on Iranian oil or because of the tanker’s links to a sanctions-designated Russian bank, Promsvyazbank.
One of the two seized Greek vessels, the Delta Poseidon, operated by Delta Tankers, was in international waters 22 nautical miles off the shore of Iran, when an Iranian naval helicopter landed on board the ship and took the crew hostage, according to Greece’s foreign ministry. The ministry added that a similar incident had occurred near Iran, but did not name the vessel.

Iran captured two tankers in the Strait of Hormuz, said U.S. officials. The Islamic Revolutionary Guard Corps (IRGC) claimed that it had seized a British-flagged oil tanker, Stena Impero, because it was violating “international regulations,” but denied seizing the Mesdar, a Liberian-flagged tanker that the U.S. alleged was also seized.
Stena Impero, owned by the Swedish company, Stena Bulk, could have been seized in retaliation for action taken against an Iranian tanker by the U.K. Royal Marines weeks before, though Tehran denied such allegation. The ship was released in September 2019 from the Iranian Bandar Abbas port.

The Iranians denied seizing the Liberian-flagged Mesdar, an oil tanker owned by a U.K.-based company, in the Strait of Hormuz, weeks after an Iranian official vowed retaliation for the British navy’s seizure of an Iranian tanker in Gibraltar for violating E.U. sanctions. The Iranians claimed that the Mesdar was merely stopped and warned of “safety and environmental issues.” The Mesdar was then allowed to continue on its journey.

In an act of self-defense, the U.S. Navy downed an Iranian drone in the Strait of Hormuz, said former President Donald Trump. The unmanned aerial vehicle (UAV) came within 1,000 yards of the U.S.S. Boxer, a distance which Pentagon spokesman Jonathan Hoffman referred to as a “threatening range.” This incident took place just under a month after Iran shot down a U.S. surveillance drone which it claimed was flying in its airspace. Iran denied Trump’s assertion, and released video footage purportedly showing the drone in flight after it was allegedly shot down.

U.S. officials suspect Iran seized the Panama-flagged Riah, an oil tanker that disappeared near Iranian waters after its transponder was switched off. The ship’s last known location was the Qashm Islands, where the Islamic Revolutionary Guard Corps (IRGC) has a navy base.
The Supreme Leader of Iran Ali Khamenei’s statement that Iran would retaliate for a British seizure of an Iranian supertanker in Gibraltar earlier in July added to the suspicion. British authorities seized the tanker, Grace 1, on the assumption it was transporting oil to the Assad regime in Syria in contravention of E.U. sanctions.
On July 18, Iranian state television quoted an IRGC official saying that the paramilitary had seized a tanker earlier in the month on grounds that it was smuggling Iranian fuel, though he did not identify the ship. A semi-official Iranian news agency later quoted a defense official saying that it was the Riah that was towed for repairs in Iran; and on July 27, Iran released nine of the twelve Indian crew members that were detained.

Armed boats of the Islamic Revolutionary Guard Corps Navy (IRGCN) approached the BP-owned British Heritage oil tanker in the Strait of Hormuz and ordered it into Iranian waters, but they were deterred by a British Royal Navy frigate, the HMS Montrose, which was escorting the tanker. The HMS Montrose pointed its guns at the IRGCN boats and warned them over radio, at which point they dispersed. A U.S. Navy aircraft carrier filmed the incident, but the IRGCN denied that it occurred. Iran’s then foreign minister, Mohammad Zarif, dismissed the situation as “worthless” and intended to “create tension.”

U.S. Intelligence officials determined that Iran was responsible for explosions that severely damaged two oil tankers in the Gulf of Oman – the Kokuka Courageous and the Front Altair – based on evidence of the weapons used, expertise and resources required, and similarity to other Iranian attacks on shipping vessels.
U.S. Central Command (CENTCOM) released a video showing an IRGC patrol ship pulling up alongside one of the damaged vessels after the explosions to remove unexploded limpet mines, presumably to cover up their involvement in the attack.

Iran was suspected of sabotaging four commercial vessels outside the Strait of Hormuz. The U.A.E. identified the ships as two crude oil tankers owned by the Saudi shipping firm Bahri; a UAE-flagged fuel bunker barge; and a Norwegian-registered and owned oil tanker. An Iranian lawmaker blamed “saboteurs from a third country,” while a U.S. official familiar with U.S. intelligence said that the attacks “fit [Iranian] M.O. [modus operandi].”
Former U.S. National Security Advisor and current UANI advisor John Bolton said that the attacks were “almost certainly” carried out by Iran. The attacks were thought to be Iranian retaliation for the U.S.’s decision in 2019 to end the waiver program that allowed some countries to import limited quantities of Iranian oil without facing U.S. sanctions.

Thirty Islamic Revolutionary Guard Corps (IRGC) vessels shadowed the U.S. aircraft carrier U.S.S. John C. Stennis and its strike group in the Strait of Hormuz, at one point launching rockets away from the aircraft carrier and flying a drone nearby.
The U.S. aircraft carrier was abiding by international law, as the Strait of Hormuz is viewed as an international transit route, despite the fact that it is within the territorial waters of Iran and Oman. Iran on multiple occasions has threatened to shut down this narrow passageway, through which over a third of seaborne oil flows.

Six boats under the command of the Islamic Revolutionary Guard Corps (IRGC) trailed the U.S.S. Essex in the Persian Gulf, two of which came within 300 yards of the American warship.
General Joseph Votel, who was on the U.S. vessel at the time of the incident, said to reporters that the Iranian maneuvers were commonplace and did not rise to the level of “unsafe and unprofessional” activity. Nevertheless, the Iranians appeared to photograph the U.S.S. Essex, and a U.S. official aboard the ship said that Iranian personnel had threatened to shoot down a naval helicopter flying off the U.S.S. Essex.

Despite repeated warnings via radio call to stay clear of the F/A 18-E fighter jet, which is assigned to the U.S.S. Nimitz aircraft carrier, an Iranian QOM-1 drone flew in close proximity to it while it was preparing to land after conducting flight operations in airspace above the central Arabian Gulf. As a result of the “unsafe and unprofessional actions,” which constituted a violation of international maritime laws and customs, the F/A 18-E had to swerve out of the way to avoid a collision, said a statement by U.S. Central Command (CENTCOM).
