As of May 2026, the Strait of Hormuz has transformed into a high-stakes arena for asymmetric naval warfare. While Iran’s conventional navy faced significant losses earlier in the year, its "Mosquito Fleet" , a force of hundreds of high-speed, heavily armed small boats, remains largely intact and more lethal than ever. In my opinion, these vessels are the true "backbone" of Tehran’s strategy, turning the narrow waterway into a tactical nightmare for the U.S. Navy's Fifth Fleet.

Asymmetry in Action: Speed vs. Tonnage
The IRGC Navy (IRGCN) has refined a doctrine that leverages geography and cost-asymmetry. These small craft, often hidden in coastal caves and tunnels, can swarm commercial tankers and warships in minutes. I suspect that the recent deployment of Seraj-1 fast boats and missile-equipped speedboats is a deliberate move to saturate the defensive systems of U.S. destroyers like the USS Mason.

Counter-Swarm Measures: "Project Freedom"
In response to the surge in attacks, the U.S. has launched "Project Freedom" to safeguard maritime trade. I suspect that the increased use of AH-64 Apache and MH-60 Seahawk helicopters is currently the only effective way to counter these swarms.
FAQs
What is Iran's "Mosquito Fleet"? It is a force of 500 to 1,000 armed speedboats operated by the IRGC, designed for hit-and-run attacks and swarming tactics.
Can these small boats actually sink a U.S. Destroyer? While unlikely to sink a destroyer in a single hit, a coordinated "swarm" can overwhelm a ship's Close-In Weapon Systems (CIWS) and cause significant operational damage.
