Iran's 'mosquito fleet' comprises a flotilla of small, fast boats designed for asymmetrical warfare, primarily operated by the Islamic Revolutionary Guards Corps (IRGC). This fleet plays a crucial role in controlling the Strait of Hormuz, a vital maritime route for global oil shipments. Despite claims by the US and Israel of having destroyed many Iranian warships, the mosquito fleet continues to pose a significant threat due to its stealthy operations. These boats are modified recreational vessels equipped with rocket-propelled grenades and machine guns, capable of speeds up to 100 knots (approximately 185 kilometers per hour). The IRGC employs guerrilla tactics, relying on hit-and-run attacks rather than traditional naval engagements. Analysts estimate that while the US-Israel coalition has targeted about half of the IRGC's fast attack boats, hundreds to thousands remain operational, often hidden in fortified caves along the Iranian coastline. This makes them difficult to track and poses a persistent threat to commercial shipping in the Strait of Hormuz, complicating maritime security efforts in the region.
