The Iranian Revolutionary Guard Corps Navy (IRGCN) is a branch of the Islamic Revolutionary Guard Corps, responsible for naval operations in the Persian Gulf and surrounding waters. Established after the 1979 Iranian Revolution, its primary mission is to protect Iran's maritime interests and enforce its naval policies. The IRGCN operates a variety of vessels, including fast attack boats and submarines, and is known for its asymmetric warfare tactics. The IRGCN plays a significant role in regional security dynamics, often engaging in confrontations with foreign naval forces. It is also involved in protecting vital shipping routes, particularly through the strategic Strait of Hormuz, where a significant portion of the world's oil supply passes.
