Iran has maintained control over the Strait of Hormuz despite suffering naval losses from joint U.S. and Israeli strikes. Using small, fast boats collectively known as the “Mosquito Fleet,” Tehran continues to pressure U.S. forces in the region. The Islamic Revolutionary Guard Corps (IRGC) deploys these vessels separately from Iran’s regular navy, capable of launching drones and missiles from hidden coastal bases. On Friday, Iranian Foreign Minister Abbas Araghchi announced via social media that the strait had been fully reopened, a move welcomed by U.S. President Trump, who said American port blockades would remain until a peace deal is reached.

Experts describe the IRGC’s naval tactics as guerrilla-style, relying on surprise attacks rather than conventional warfare. Analysts note that many of the small boats are difficult to detect by satellite and can be deployed within minutes from concealed bases along Iran’s rocky coast. The IRGC’s maritime force, numbering around 50,000 personnel, operates across five sectors and maintains at least ten secret bases along the Gulf.

U.S. naval officials and analysts warn that these small, fast attack boats, along with drones and missiles, continue to pose a serious threat to commercial shipping in the Gulf and the Strait of Hormuz.
