Three Saronic Corsair one-way attack unmanned surface vessels struck Iran's Bandar Abbas Naval Base over the weekend of July 12-13, destroying a docked Ghadir-class midget submarine in what US Central Command described as the first combat employment of armed sea drones by American forces. CENTCOM said the strike degraded Iran's ability to continue attacking commercial shipping in and around the Strait of Hormuz. The attack came as US and Israeli strikes resumed following the collapse of the Islamabad Memorandum ceasefire framework agreed in mid-June.
Daily figures from IMF PortWatch around July 12, 2026; the day's value is compared with the trailing 30-day average. Week comparisons are shown only when the series covers both full weeks.
IMF PortWatch data published on GMN's Strait of Hormuz tracker shows commercial ship transits averaging 3.17 a day over 1-6 September 2026, against 85.5 a day in 2025; other counters read higher, but every independent count is a small fraction of the pre-war norm.
Iran's Revolutionary Guard said on 8 September 2026 it had recovered a US Navy Anduril Dive-LD autonomous underwater vehicle at the entrance to the Strait of Hormuz; US Central Command said the vehicle had malfunctioned more than a day earlier, and Anduril confirmed the loss.
The United States decommissioned its four Bahrain-based Avenger-class mine hunters in September 2025 and shipped the hulls home in January 2026. When Iran began mining the Strait of Hormuz two months later, according to CENTCOM, the Navy had to sail two of its last four minesweepers from Japan.
