US strikes degrade Iran’s Strait of Hormuz capabilities, ISW says

Key Points:

• The Institute for the Study of War (ISW) assessed that US attacks have significantly degraded Iran's ability to surveil and lay mines in the Strait of Hormuz, as evidenced by increased oil flows through the southern route on September 1.
• US officials reported that about 40 vessels carrying millions of barrels of oil transited the strait on September 1, with over 17 million barrels transported on August 31, nearing pre-war export levels.
• Iran's Islamic Revolutionary Guard Corps (IRGC) has resorted to less effective methods like shore-based rocket launchers and physical vessel identification due to degraded radar and mine-laying capabilities caused by US strikes.
• Despite Iranian claims of new mines being laid, US Central Command stated that mines have been cleared and pathways through the strait remain effective, though Iran continues efforts to rebuild its radar systems.
• On September 1, CENTCOM targeted Iranian air defense, radar, maritime, mine-laying, and communication sites, with ISW noting Iran will likely persist in attempts to control the strategic Strait of Hormuz.
