TEHRAN, July 11 — The Islamic Revolutionary Guard Corps Navy, a branch of Iran’s military established in 1979 after the Iranian Revolution, operates as a distinct force separate from the regular Islamic Republic of Iran Navy. Its focus on asymmetric warfare, utilizing small fast boats, anti-ship missiles, and naval mines, has made it a central instrument of Tehran’s power projection in the Persian Gulf. The IRGC Navy fields approximately 20,000 personnel and maintains bases along the Persian Gulf, including at Bandar Abbas and on Abu Musa Island.
The United States designated the IRGC as a terrorist organization in April 2019, a move that underscored the growing tensions between Washington and Tehran. Rear Admiral Alireza Tangsiri, appointed as the IRGC Navy’s commander in 2018, has publicly threatened to close the Strait of Hormuz multiple times.
The strait, a narrow waterway through which a significant portion of global oil shipments pass, has been a flashpoint in Iran’s confrontations with Western powers.
Exercises and Seizures
The IRGC Navy has conducted numerous exercises under the Great Prophet series, showcasing its capabilities in the region. In July 2019, the force seized the commercial tanker Stena Impero, an action that drew international condemnation and highlighted the risks to commercial shipping in the Gulf. The force’s actions are overseen by Iran’s Supreme Leader, Ali Khamenei, who holds final authority over military strategy.
This chain of command ensures that the IRGC Navy’s operations align with the broader objectives of the Iranian regime.
Asymmetric Warfare Doctrine
The IRGC Navy’s reliance on small fast boats and anti-ship missiles reflects a doctrine designed to counter the technological advantages of the U.S. Navy and its allies. By deploying naval mines in key chokepoints, the force can disrupt maritime traffic without engaging in conventional fleet battles. Analysts have noted that the IRGC Navy’s emphasis on asymmetric tactics makes it a persistent threat to stability in the Persian Gulf.
Its ability to rapidly mobilize and strike at commercial vessels or military targets keeps the region on edge.
Looking Ahead
As of July 2026, the IRGC Navy remains a key component of Iran’s military posture. With Rear Admiral Tangsiri at the helm and the Supreme Leader’s backing, the force is likely to continue its pattern of provocative exercises and seizures. The U.S. administration, under President Donald Trump, has maintained a firm stance against the IRGC’s activities, but the risk of escalation in the Strait of Hormuz persists.
