The IRGC Aerospace Force primarily used Zolfaghar short-range ballistic missiles — a single-stage, solid-propellant weapon derived from Iran's Fateh-110 family, with a range of approximately 700 kilometers. The Zolfaghar's guidance has been upgraded to use China's BeiDou-3 satellite navigation system, which uses frequency-hopping and encryption that analysts say maintains roughly 98 percent accuracy even under heavy US electronic warfare jamming. That upgrade is what makes current Zolfaghar strikes qualitatively different from earlier Iranian ballistic-missile salvos: jamming that previously degraded missile accuracy no longer reliably does so.
