Iran has launched a fresh wave of retaliatory strikes against American targets across the Middle East, with state media and IRGC-linked outlets highlighting the use of advanced solid-fuel ballistic missiles, particularly the Kheibar Shekan. The strikes came after U.S. attacks targeted Iranian radar sites, coastal air defenses and military infrastructure near the Strait of Hormuz. Unlike older liquid-fueled missiles that require lengthy preparation and fueling procedures, solid-fuel systems such as the Kheibar Shekan remain permanently fueled and ready for launch at short notice. Mounted on highly mobile transporter-erector-launchers, these missiles can rapidly emerge from underground facilities, fire within minutes and relocate before counterstrikes arrive.
